Screen Sharing (video resolution?)

I have tried Screen Sharing both to a bigger monitor and a smaller one. Sharing to a smaller monitor seems problematic because the mouse becomes hyper sensitive. It's near impossible controlling the mouse. Sharing to a bigger monitor the mouse works great, but the image is smaller and at times barely readable. I suspect this is a monitor-to-monitor resolution issue and am wondering if there is any work around or fix for this problem. Thank you.

Hi,
In iChat Menu > Preferences > video section set the Bandwidth at both ends to 500kbps as a starting point.
You could go as low as 200kbps as Screen Sharing is supposed to come in lower than this.
The Open the Connection Doctor during a Chat (Video menu)
This will tell you the Bit rate from your end and the Buddy's
Move the Bandwidth up at one end and see when the Buffering settles to a new speed (bit rate)
Adjust one end at a time allowing for the Buffering to work until you have the highest setting you can at both ends with a decent pic.
iChat 3 and 4 was capped at 1.5 Mbps by the Quicktime Streaming setting (System Preferences > Quicktime).
This setting is not there in Snow Leopard and iChat 5 "sees" all your connection speed.
If you and your Buddy have vastly different Upload speeds (the deciding factor) there can be issues with the iChat Buffering.
This applies to Video chats as well as Data intensive Screen Sharing.

  • Can't start Screen Sharing, Video Chat, or Audio Chat

    Hi there,
    I've been through countless Apple Discussion and other website threads, but I can't figure this out.
    I just got my dad a brand-new iMac with Mountain Lion 10.8.3 on it. I'm using a MacBook Pro, also with 10.8.3 on it. We're both using the Messages app, signed into our respective Google Talk accounts (not Apple IDs with Google email addresses).
    But for the both of us, "Invite to Video Chat," "Invite to Audio Chat," and "Share Screen With..." are grayed out in the Buddies menu, even though both of us have "Video Chat Enabled," "Audio Chat Enabled," and "Screen Sharing Enabled" checked off. I unchecked the option to consolidate the various Buddy Lists in the Messages > Preferences > General pane, and when I go to my Gmail account's Buddy List, I see the four buttons underneath the list (with my dad's name highlighted), but only the "A" button is clickable--not the other buttons for Audio (the phone icon), Video (the camera icon), or Screen Sharing (the two rectangles layered over one another icon).
    Does anyone have any ideas on how to remedy this (short of using a completely different method of screen sharing)?

    HI,
    On your GoogleMail Page pull down your own Name/ID
    Click Account
    Choose "Products" from Menu.
    Enable "Talk" (Sign in to Dashboard far right)
    This is separate from the settings to actions on the Web Mail Page accessed in the Settings icon.
    However I am not sure if the setting absent there if TALK has not been enabled as it was done some time ago for for me as well.
    Jabber apps can have  Priority Setting to allow people to be logged in via several devices and be sure a messages goes to the right device at the time.
    iChat version 3 through 5 had the same Priority as the Web Browser login and would stop text Messages getting through.
    iChat would show the Buddy still on line if they were logged in via the web page at a later stage
    but the Video and Audio green icons would disappear from the Buddy List and the icons at the bottom would be greyed out.
    Messages has a default priority of 0 compared to iChat's 23.
    However I have never managed to work out which end of the scale outranks the other.
    Essentially logging in to Google Mail web page to Check things is likely to stop the ability to Video chat.
    This is because Jabber app use a Protocol  called Jingle to connect and this is not compatible with the SIP iChat and Messages uses.
    It is included in the Web Browser Plug-in you can get from Google.
    The default setting for the Bandwidth setting is the NONE one.
    However it can pay to set it to 500kbps.
    This helps when  internet speeds that are faster vary too much for the Buffering in iChat and Messages to work.
    In broad terms a 5% variance in a 10Mbps download speed can be 500kbps.
    Forcing Message to only use 500kbps is fast enough for 4 way video chats but is well below any variance interference.
    It can also help where the ISP slows the connection as it thinks it is a Peer-to-Peer file sharing event.
    Video and Audio chats (including Screen Sharing) are peer-to-Peer connections.

  • IChat screen sharing and video not working on MacBook but works on Mac pro

    I have a MacBook and MacBook pro. Both have the lion os 10.7.2. I can use iChat on the MacBook pro for screen sharing, video chat, and text chatting, with others remote to me. However, I can only do texting with the MacBook.  I can do screen sharing via Finder between my MacBook and MacBook pro. I can do FaceTime between both systems. I can also do FaceTime between the MacBook and anyone remotely.
    I also tried installing teamviewer on the MacBook, and on a remote MacBook..... And I get the same results where I cannot share the screen, from the one that has not been working.
    I have checked the settings under system preference and made sure screen sharing was enabled. I have checked under iChat under video to make sure screen sharing was checked.
    The macbook that is having this problem is configured for AIM for iChat
    I have run out of ideas. Any suggestions on what I might try?
    Thanks

    Ok,
    I will list the ports in greater detail and point out when iChat uses them.
    AIM Login and 1-1 Text Chatting
    iChat version 1  through 5 will Log in to the AIM server on port 5190 (TCP Protocol) by default.
    Since iChat 2 we have been posting here that the AIM servers allow a Login on almost any port and have been suggesting port 443.
    This is used by both Web Browsers for secure Login to some sites and by the Mail app with some mail servers.
    It is also below port 1024  (most domestic routers have the ports above this figure closed)  In some campus situations using port 443 will normally allow at least Login and Text chatting.
    iChat 6 uses port 443 by default.
    File Transfers (AIM)
    When doing File Transfers with AIM Buddies iChat will move to using Port 5190 on the UDP Protocol.
    This cannot be changed.  (This invokes the little Message about Starting Direct IM in an open Chat)
    It also uses this port for Pics-in-chats, dropping Files on a Buddy's name with out a Chat or sending other files that are not pics.
    In the case of Port Forwarding some devices don't like port 5190 being forwarded "twice" which is another reason for moving the login and Text chat port.
    Jabber Logins
    No matter what Jabber server you use ichat will use one of two ports (5222 and 5223)
    Which one it uses is dependent on whether it needs and is using an SSL Login or not.
    SSL Logins use port 5223 and NON SSL one use 5222 (ticking or Unticking the SSL box on a Jabber account will automatically change the port).
    Google Talk is the exception in that it allow a Login on port 443 as well.
    The First Apple Doc I linked you to says iChat uses port 5220 in Jabber.
    I run Little Snitch and have never seen any version of iChat use this port at any time.
    Bonjour
    Any Mac to Mac Connection or Mac to any Bonjour able peripheral will be on port 5353.
    This is normally opened (Preset) in the Mac Firewall for the Finder/System side of Sharing.
    iChat needs and uses two other ports  (5297 UDP and 5298 on both TCP and UDP)
    As they an LAN Side connections the router would normally pass them.
    At iChat 3 there were issues with the Mac Firewall (it included UDP set up and the preset in the firewall only listed them and TCP so we had people add all the iChat ports  (you had to manually enter them in Tiger)
    A/V Chats
    No matter which Buddy List you start from iChat will do A/V chats the same way.
    The Visible Invite you or your Buddy sends is on port 5678 (UDP)
    In iChat 3 and earlier iChat then moves to port 5060 to send the SIP Connection Process invite behind the scenes  (SIP = Session Initiation Protocol)
    Port 5060 is one of 4 ports internationally agreed for SIP (How VoIP phones connect) (5060-5063).
    Although ISPs were not supposed to block Through traffic many started blocking End users  and then Charging them to open these ports (Many ISP were telecom companies that were losing long distant Telephone calls monies).
    The SIP process then in iChat 3 contacts a server run by Apple for this purpose (Snatmap.mac.com to give it it's full name).
    This acts like a old fashioned telephone operator connecting the call.
    SIP is a text based process.
    Your end "Calls" the operator.
    The Operator "Calls" Buddy.
    Buddy Accepts
    iChat then negotiates the ports to be used.
    In iChat 2 and 3 it uses 4 ports (vid in Vid out, Audio In and Audio Out) from "the group of 20" starting at the bottom (16384 to 16387 normally)
    Three and 4 way chats uses more ports (which is why 20 are set aside)
    In iChat 4 Apple realised the issue with the 5060 port and changed the way iChat worked
    Since then it has Sent the invite on Port 5678 but then moved to port 16402 (it starts at the top of a smaller group of 20)
    All Video and Audio traffic is also now on one port  (so no need for 20 ports and iChat now lists 10).
    NOTES so Far.
    File Sharing during a Chat converts the Chat to Direct IM for AIM Logins
    This is Peer-to-Peer in AIM
    A/V Chats are Peer-To-Peer and you can actually log out of the Buddy list and continue the chat. (The exception is using iChat 6's  AIM Video relay option)
    Screen Sharing
    Screen Sharing is an Audio Chat with a VNC connection along side.
    Both bits have to wok to avoid the Pop-up to send to Apple and the Log that contains.
    The Audio part is on port 16402 and the VNC part is random. (So random it is different every time you do it)
    The reason it is classed as an Audio Chat+ is so the AppleScript for Auto Accept can  filter out Screen Sharing connection and Not Auto Accept them.
    This does have a knock on effect as far as your Router is concerned as already mentioned earlier.
    You cannot Forward or Trigger the random Port so you have to use UPnP in your router to open the ports.
    NOTES
    Jabber File sharing may possibly be on port 1080 as listed in the Server Article I linked you to (I have also seen it written about in other stuff I have come across)
    However Little Snitch does not seem to confirm this either.
    Most time it will be peer-to-peer like the AIM connections for this.
    However some Jabber servers do not seem to allow this and have this Jabber65 Proxy set up which passes things Server to Server in between it leaving your end and arriving at a Buddy.
    This on  Port 7777 but you do not need to open this port (unless you are running a Jabber server)
    I have yet to test File Transfers using a Yahoo Buddy List in iChat 6.
    AppleCare and Geniuses.
    Previously I have been contacted by Geniuses in Stores asking to test customer's iChat.
    They and the Applecare people have details about Apple wants an designed the App to work.
    What they don't have is the knowledge about what it takes to set it up in the "real world".
    There are literally thousands of Makes and Models of routers.
    Some like the Thomson-Alcatel brand state they are SIP/VoIP ready but this means the router strips out all SIP Data trying to send it to a Phone.
    Early models of Alcatels can get around this with a tweak. Later models can't.
    Motorola devices tend not to have UPnP.
    Apple Base Stations have Port Mapping Protocol instead of UPnP and this needs setting up.
    The Zyxel range definitely does not like the dual use of port 5190 and does much better using UPnP (You almost certainly have to do your AIM login on port 443 with these).
    1. I have two computers (MacPro and MacBook Pro) that are both running Lion 10.7.2 and both running iChat 6.0.1.  <<-- Fine
    2. The Netgear router model is: WNDR3700.    <<<<---  With any Brand there are exceptions and I do wonder about this one
    3. The firewall for both Macs is turned on and in the advanced area iChat is listed as being "allowed."  <<<<---- Fine
    4. In iChat, under the video options, "Screen Sharing Allowed" is checked.                                        <<<<<---- Fine
    5. In System Preferences, "Screen Sharing" is checked and this is for "All Users" at present.               <<<<<---- Not Required
    6. There are two separate AIM accounts being used for iChat purposes.                                            <<<<<----  OK
    7. In iChat preferences, each AIM account is "Enabled" under "Account Information" and the "Server Settings" show the Server as "api.oscar.aol.com" and the Port is "443" and "Use SSL" is checked.                                <<<<---- As it should be
    From this and the other info in the first port it was only the router set up that seem to throw some light on a possible cause (Port Forwarding and UPnP conflict)
    If just doing Port Forwarding the ports listed would have covered things (Except the Screen Sharing's random port)
    Regarding your latest post.
    I have  table similar to that on my Sagem 2504Fast Modem/router combined device and it too seems to list a different port on the external side on occasions.
    I would try the router with the Disable SIP ALG unticked (so it is not disabled). If the Help info on the right gives any info about what this Netgear version does it would be helpful.
    Some are like the Thomson-Alcatels I was talking about in that it points the SIP data to a specific place (Possibly a Phone socket on the device)
    Others seem to provide an "boost"  to enable SIP to work and don't seem to get in the way of iChat.
    Try adding the Names in Table 1 from this page and see if you can Video to those.
    There are 6 names in total (I am actually only seeing one on Line as I type)

  • Video/Screen Sharing via 3G connection not possible - port restrictions?

    I'm running Jabber-based iChat AV 5.0.3 sessions from my MBP connected to the Internet via a wireless USB modem 3G/UMTS (German Telekom D1 network). My buddies are connected to the Internet via regular broadband connections (DSL). I have set up a hosted Jabber server via Dreamhost (without SSL, port 5222 used).
    Status Quo:
    - Contact status of remote Jabber users shows up properly. All buttons (text chat, screen sharing, video) are available (not greyed out) on both sides.
    - Text chat works fine.
    - Video chat and screen sharing can be invoked from both sides (confirmation window shows up), but after confirmation the initiation process doesn't finish successfully. The video/screen sharing session doesn't run. *iChat AV shows a message indicating that it doesn't receive an answer from the remote user device.* If the iChat session is initiated from a buddy's computer, the buddy gets the same message respectively.
    - For testing purposes, I changed the internet connection on my MBP from the mobile 3G USB modem to a regular *DSL broadband connection (same ISP, German Telekom). In this scenario, video/audio calls and screen sharing work flawlessly!* Therefore, I assume that the problems in 3G connection mode is caused by the ISP (German Telekom) blocking/restricting ports required by iChat AV for initiating the video call and streaming the data on their 3G network.
    Is there any way to bypass ISP restrictions, by either changing specific iChat AV port settings on both ends (client devices) or by port forwarding? If yes, which settings should I change? Unfortunately, it's couldn't find any document indicating which ports are opened/allowed by German Telekom's 2G/3G (GSM/UMTS) network.

    Hi,
    Does this 3G device have any set up functions that are on your Mac ?
    If it does not it is likely that it is wide open to all Port (65535 of them).
    I presume that in System Preferences > Network you see a Public IP when using this device ?
    Again this would tend to pint to all the ports being open.
    Is there anything on the ISP's web site that suggests this device is unsuitable to be used with VoIP or SIP connections ?
    VoIP (Voice over the Internet) uses the SIP connection process the way iChat does.
    Most likely the issues is the way packets are sent.
    When you do a download, for instance, do you find the speed increases in the first few minutes ?
    When some data packets are sent over the Internet the next one is not sent until confirmation that the first has arrived.
    This Latency effects Point to Point WiFi (antenna to Dish on House) and satellite connections mostly particularly when it is a two way thing.
    It can effect Mobile/Cell phone type connections.
    What sort of Speeds are you getting on the 3G device ?
    http://www.speedtest.net/
    Do these seem to get faster as the time proceeds ? (this can be difficult to spot).
    The Log mentions one end being at just over 2Gbps although it does not make it clear which end.
    As the Remote end is the end that reports "Router: Port Restricted" and it works over standard DSL we have to presume they have the ports open.
    You could try restricting iChat 's Bandwidth in iChat menu > Preferences > Video Section to 500kbps (try it at both ends)
    If that does not work try 200kbps
    This may stop iChat from trying to send data too Fast for the Network Connections.
    Realistically there are a few too many variables here.
    It could be Speed of data throughout at the Initiation point. (Slow Start up of data transfer)
    It could be an Internal setting preventing SIP.
    It could be that the 3G network sends and receives data by different routes.
    (I have seen this once when a ISP was repairing some Cabling. To maintain end user speeds they managed their own network to split Incoming and outgoing data to the end point.)
    iChat does not like this as it checks the IPs and the Hops (number of intermediate stages/servers) and if the data is different it will not connect (Man in the Middle attack protection).
    I can't remember the last time I knew of someone being successful with either an 3G USB dongle or a 3G phone as Modem (internet Sharing).
    Despite my ideas I think you will be unlucky and this will not work.

  • Screen Sharing, audio, and video chat not working with certain people

    My ichat application will suddenly stop working after just a few seconds of starting wither screen sharing, video chat, or audio chat. I get the error message "No data has been received for the last 10 seconds." How do i go about fixing this?

    Hi,
    This message can be caused two ways.
    1) a loss of Internet Connection through a Physical means.
    (turning Off Airport card, Pulling out Ethernet Cable, modem or router failure, loss of service from ISP)
    2) A router or modem Software intervention.
    This most commonly happens in Video chats. The device has a feature called DOS (Denial of Service) which with modern Internet Speeds and Video Streams gets to the threshold where it cuts in. It requires that you turn the feature Off as there is not adjustment in the threshold at which it works.
    A similar feature with a similar result is SPI (Stateful Packet Inspection).
    Having said that, it very unusual to have it effect Audio only chat or Screen Sharing.
    This means the issue could be at the Buddies end.
    NOTES:
    iChat creates Logs of Connection Failures of which there are about 5 types, caused by various issues in the connection Process.
    The 10 Sec Error message covers those things where the connect End but iChat did not receive a "BYE" message (a controlled End to the Chat) or get a failure of another sort.
    Basically you were connected properly (even if you did not hear or see the Buddy) and so other event cut the connection that was not iChat related.
    Can you do Video chats with any of the 6 names in Table 1 ?
    http://www.ralphjohns.co.uk/ContactTesters.html
    Some of those will respond to Audio Only invites.
    (I just tested 4 of them and three play music and one the Audio form the Jonathon Ive Video)
    Do any of those work ?
    That will exclude a Modem or Router Issue with DOS or SPI on the remote end.

  • Why is Messages screen sharing icon grayed out?

    Trying to do remote screen sharing with my mom's Mac using the new feature in Yosemite.
    If you're not familiar with it, the new method does not require AIM, Jabber, etc and is independent of screen sharing settings in System Preferences (per Messages Help).
    The procedure is:
    In the main Messages window, select the name of the person you want to share with or, if you haven't previously exchanged messages, do so now.
    Click 'details' on the right of the top bar of the main window.
    In the menu that pops up, there are three icons: screen sharing, video chat, and audio chat/phone call. Click the screen sharing icon and send a request.
    Today, my mom signed into her Messages account and we successfully exchanged iMessage messages (not SMS).
    When I clicked 'details' the screen sharing and phone call icons were grayed out (or, more accurately, 'blued out' - they were a fainter shade of blue).
    I clicked another name in the Conversations list and then clicked back to my mom's name. When I clicked 'details' this time, the screen sharing icon was no longer grayed out, so I sent a request to share her screen. She didn't receive the request, so I canceled it.
    When I clicked on 'Details' again, the screen sharing icon was grayed out again. As far as I know, nothing had changed on my mom's end.
    What could cause the screen sharing icon to be grayed out? And what could cause it to toggle back and forth between grayed out and normal?
    Both computers are running the latest version of Yosemite, 10.10.3. Mine is a 2009 Mac Pro 8-core with 16 GB RAM, hers is a MacBook Pro from around 2012 or 2013.
    Thanks!

    Hi,
    (He did say that he'd heard that due to changes in Google's system that their accounts no longer work with Messages.)
    What he has heard and what are true are two different things
    Logged in Google account
    There are issues with Messages using SSL to login to the Google Talk server and Google saying SSL is Less Secure (there is a  setting to Enable Less Secure apps like Mail that also uses SSL and Messages).
    Some people find that 2 step Verification cannot be set at Google's Account settings if your want to use the Less Secure Apps setting.
    1. I deleted my AIM account from Messages and had my mom do the same. The result is that we each only have two items in the Accounts window of Messages: an iMessage account (signed in with our Apple IDs) and a Bonjour account.
    2. Clicking on the Details menu, the screen sharing icon was available for both of us. It was not grayed out.
    This is using two different Methods of Screen Sharing in Messages (It is silly it has two but there we go)
    For AIM use the Buddy List and the icons at the bottom or highlight the Buddy and use the Buddies Menu
    DO NOT USE the Details option.
    For iMessages start text chat then use the Detail Option an NOT THE BUDDIES Menu.
    For the iMessages Method you have to Enable System Preferences > Sharing > Screen Sharing to allow the App to be Invoked.
    (It is like FaceTime is invoked but only works to Macs)
    As you mention the Connection Doctor only refers to the older "iChat Method for Aim and Jabber and Bonjour - if you can Video you should be able to Screen Share with that method.

  • Can't share screen or video chat with AIM

    I'm trying to set up screen sharing and video chat with other AIM 'buddies' but the little icons for both remain greyed out when I select the buddy if the buddy is an AIM account. I also have messages configured for my GMail account. When I click on a GMAIL 'buddy' those icons switch from grey to active. So it looks like I can start a screen sharing/video chat session with GMail but not AIM folks. Any thoughts on what could be the problem? I've already deleted all iChat related preferences from my ~/Library/Preferences folder.  This system was an upgrade from Lion which had had iMessages beta on it.
    Thoughts? Thanks,
    -Noah

    Hi,
    Video Chat requires that you have a enough Internet Speed.
    A minimum of 128kbps upload (normally the lower) is required.
    However this is the Apple declared minimum and  a real world figure of 256kbps is best.  (it is several times the fastest possible Dial up speed).
    As Screen Sharing in iChat is basically an Audio Chat + then you have to be able to Video Chat (Same min speed requirement) first.
    Screen Sharing also requires a random internet port that means using UPnP in your router or Modem to Open ports.
    If the icons at the Bottom of the Buddy List are greyed out go to the Video Menu.
    Check the Video Chat Enabled is ticked and the same for Screen Sharing.
    If they are then open the Connection Doctor from the same Menu and check Capabilities.  (report these)
    Having said that the Internet Speed you have and the Settings would effect both types of Buddy list.
    That leaves the type of Applications the Buddy is using.
    Jabber (In this case GoogleTalk ) Buddy lists will not video or Audio chat to people logged in via a Browser or the Google Talk App for PCs or other Non iChat/Messages  but Jabber able apps on PCs or Macs (it is only iChat or Messages the Buddy has to have).
    An AIM Buddy could be logged in via AIM Express (Access via a Browser)
    This would tend to have them Not show the Video or Audio iCons (green ones in the Buddy list) rather than "disable" the Buddy List icons.
    Having laid it all out with some suggestions I am now confused.
    Go to the General Section of the Messages Preferences an untick the item about gathering all Accounts into one list.
    This will create at least two Buddy Lists (Jabber/Google and AIM).
    The settings in the Video menu should effect both Buddy lists.
    If you toggle Off and On again the Video, Audio and Screen Sharing options does anything change ?
    The Messages Beta issue will not be a factor.

  • Linksys Router and Screen Sharing Problems

    Hello,
    I know that problems with Linksys routers and ichat video/screen sharing have been covered here and there in this forum, but I couldn't find a definitive answer.
    If I can connect find on a LAN between two Macs, but then get a connection error when attempting screen sharing/video over the internet, what settings should I change on the Linksys?
    Thanks in advance.

    The Linksys Firewall is normally Off by default.
    There are those that try Pinging IP addresses for various reasons.
    A Malformed Ping (Ping of Death) can bring down your connection.
    To a certain extent this does then become a question of whether you are a big enough target or if someone discovers your IP and tries to do anything about it.
    Most will be looking for access to Windows computers so your Mac it that sense will protect itself.
    In about 6 years on Broadband with a Constant On Connection none of the modems I have had have reported a a Ping attack and I have had thousands of contacts with people via iChat some of which will have my IP in their Logs.
    Significant Decrease ? No

  • Ichat video not working when screen sharing into iMac in target display

    I have my MBP (current model) plugged into my 27" iMac and using it as an external monitor. If I screen share into the running iMac from my MBP, several things aren't working properly. When I try to use iChat video, iChat crashes. Full size images don't show up in iPhoto or Preview. Both of these things do work on the iMac when it is not acting as my display when screen sharing into it. Is there a fix for this? As I would still like to be able to use some functions on my iMac through screen sharing when it is being used as my display for the MBP.

    You are on your MBP. You have the iMac in Target Display Mode. You are using the iMac's display with the MBP with TDM. At the same time you are using Screen Sharing on the MBP to access your iMac.
    Screen Sharing is never a full size view, it is always a window on the Mac's display with a smaller than full size resolution.
    The 27" iMac's iSight is not available to use when the iMac is in Target Display Mode. Neither are its USB or FireWire ports.

  • HDMI: Mini - Receiver - TV resolution bugs triggered by Screen Sharing

    Hi all,
    I'm having an issue when connecting my Mini to my Samsung TV when running it through a receiver (Pioneer).  Before we had the receiver in the mix, this issue never came around.  Now that the receiver is involved, I believe this may be an issue related to the "handshake" that I've been reading about when HDMI devices try to connect to eachother.
    What works:
    - If I sit down on the living room couch, turn on the TV, receiver, and Mini, there are no issues.  The resolution is correct.
    - If I leave the TV off, receiver on, boot up the mini, and connect to it via OSX Screen Sharing... I am able to use it as a media center and play music through the mini and receiver, leaving the TV off to save power.
    What doesn't work:
    If I try to switch between "living room" mode (couch / TV) and "Screen Sharing" mode, the resolution gets all fouled up and I need to reboot the mini in order to make it usable.  Here is a screenshot showing how it looks when trying to go from "living room" mode to "Screen Sharing" mode:
    The only way to get out of here is to hold down the power button, forcing the mini to shut off abruptly, then reboot.
    Conversely, if I try to switch from "Screen Sharing" mode to "living room" mode, it's a little different - the top and bottom of the screen is cut off.  Part of the dock is off of the screen, and the menu at the top of the screen is virtually gone.  With this method, I'm actually able to move the mouse off the screen and navigate to "Apple -> Restart" so that it reboots and starts working fine again.
    I've been on the phone with Apple (yes, I have Apple Care) and they pointed me to Pioneer, saying that the mini was receiving instruction from the receiver.  When I called Pioneer, they had me turn off some "HDMI auto detect" features in the receiver but this did not resolve my problem.
    Any suggestions?  Any help would be much appreciated!
    Thanks,
    -Nate

    this is not an elegant solution but here goes.  there may be something in the pioneer that would fix you but here is a solution around the receiver.   plug the computer video into an input on the tv.  if you use hdmi - you will need a separate audio out of the computer to the receiver.  program your remote control so that it switches the audio on the receiver to the separate audio from the mini and program the remote so it switches the tv input to the hdmi.  if you keep the hdmi to the receiver you will need a different video out of the mini to the tv.  its a little complicated but it should work.

  • IChat Screen Sharing:  Audio works but video is a white screen.

    I am having a problem using iChat screen sharing with a specific computer.  We are both running OS 10.7.4.   I have a Mac Book Pro (fall 2011) and he has a iMac one to two years old.  We have tried contacting apple support but no luck yet.  We tried setting up a test user to see if the problem was user specific but encountered the same problem.  Again, video and text chat work fine.  He can share my screen with no issues.  Only when I ask to share his screen do I get a blank white screen.  Audio works and I can manipulate his curser but all I have is a white screen.  I have tried changing the resolution on his iMac but this has not helped.  Also we are both using Google Talk as the chat server. 

    Hi,
    Historically iChat Updates came in OS updates.
    Not every OS update had an iChat update but that was the way they were delivered.
    Only twice during the lifetime of iChat 3 have there ever been standalone Updates outside of this.
    Most Updates are now through the App Store but Software Update can still be used (I have mine set on Daily despite Apple's Updates normally coming on Tuesdays)
    One person stated he thought there had been a change with OS 10.8.1 saying the Build number of Messages had changed.
    In my experience it has not and when Apple do update something the build Number and Version number change.
    It is widely know that Apple send Developers and others advance copies of the OS to try out.
    Those people sign NDAs (Non Disclosure Agreements) so you will not see any discussion of any up and coming stuff on this site.

  • Corrupt video when screen sharing

    When I take control of another screen (the test computer has a smaller resolution) with my computer running the messages beta, I get corrupt video (see attachment).  Happens when the target machine is either running 10.7.3 Lion iChat, or the iMessage beta.  This makes screen sharing completely unusable.

    HI,
    It would be worth flipping that pic Vertically to see which Desktop is the one that is messed up behind the the proper display.
    Judging by the Finder's Airdrop icon and the Browser's green icon next to the Home Button I would guess it is the one on View.
    However the Home Button appears "Live" in the broken up image.
    Slingbox and "ott Neher" might provide other clues.
    As the Computer screen that is On view is from a Laptop (Battery is Charged) is it using a second Screen/Display ?

  • How can I set up a screen screen sharing VNC at a resolution higher than display?

    I have a mid 2010 MacBook Pro 13in, and i have set up screen sharing to access over VNC. I want to view my mac on my 1920x1080 display hooked up to my PC. But when i do it is not full screen, it is the same resolution as my MBP. how can i run it at a higher resolution only over VNC?

    As Cvid suggests, I create my "frames" in Photoshop. Not sure about all versions, but my PS has several Actions, just for frames, and I have made a few more, with a different "look."
    I Save_As PSD, and just Import those as Footage (I do not need the capability to work with the individual Layers).
    Good luck,

  • Screen Sharing and Video Chat

    Hi! I have 2 computers right next to eachother, and I felt like testing out the new Video Effects and Screen Sharing abilities of Leopard.
    So, I logged on to each of the computers in iChat (with 2 different accounts), and attempted to do this. However, whenever I attempt to Video Conference or Share Screen, I get an error, saying the other person (the one that accepted the request), cancelled the conference.
    So what's up with that?!
    I am sorry if this isn't clear, and I will post back with any additional info you need.
    Thanks!

    iChat requirements
    * Audio chats require a microphone and a 56-Kbps Internet connection.
    * Video chats require an iSight camera (built-in or external), USB video class (UVC) camera, or FireWire DV camcorder; and 128-Kbps upstream and downstream Internet connection.
    * Photo Booth and backdrop effects require an Intel Core Duo or faster processor.
    * Backdrop effects when using a DV camcorder require fixed focus, exposure, and white balance.
    * Some iChat features offer better performance and quality with higher system capabilities.

  • Screen Sharing and video chats don't work

    I've been searching this forum for awhile and I haven't found a concrete answer to my problem, so if this question has been answered please excuse me. Ok, So here's my situation am running iChat on Mac OS 10.5.1. Whenever I am using my laptop at my school on the network their, I am able to use both screen sharing and video chat. But when I am at home, I am unable to use either one. It begins to try to start the session, but then i receive a message that tells me that a connection could not be established. I know that I have internet access, but I don't know what could be wrong with it.

    After investing far to long in looking at this exact issue on my end, reading the seemingly endless threads on the exact same error, trying all the various tweeks and QT settings, bandwidth limit settings, etc etc. proposed here, I have now solved this problem, and the none of the above were part of the solution.
    I have perhaps one of the the most common routers on the market, Linksys WRT54GL.
    In a totally unrelated network problem (a printing issue), Linksys tech support advised me to reset my router. There is a small button on the bottom. I depressed it for 30 seconds. Rebooted everything and my printer miraculously worked. Yea, I had to reenter my WAP passkey, router admin password etc., but that took 2 secs. So, what does this have to do with iChat?.... The very next time I tried iChat video and turned on and enabled my camera, the recipient immedialty saw me. No connection error.
    Problem solved, for me art least. Not sure if anyone has tried this, but makes sooooo much more sense than the other unApple like suggestions I previous tried. Hope this helps.
