Screen sharing resolution

Hi,
I'm having a problem with screen sharing...
Before installing OSX Mountain Lion, when controlling my new mac book air, I used to be able to go into a hradware or virtual mode and change the screen resolution so I could have a far large resolution on my big iMac 27" screen.
Now the option is not available at all sinse moving to new OSX ML??
Any ideas would be great - it's driving me nuts!

Might try installing DisplayConfigX on the Server...

Mavericks: Screen Sharing Resolution changed to low-res

I just updated my two slave macs (Mac Pro, Mac Mini) to Mavericks (main mac still on 10.8.5), and when I do screen-sharing by connecting to each, suddenly I'm getting each slave mac in a square screen at low-res -- 1280x1024. THere are no other options to return these to full 1920x1080-sized windows.
Some other forums recommended a free app called Display Menu that puts a screen resolution in the upper menu bar, but when I select 1920x1080 as the resolution for the sharing window (which it has always been), I get a black screen in that window and the only fix is to turn off the slave mac manually, and when it comes back on and I reconnect to it, it reconnects with the square 1280x1024 monitor window.
It used to be that I got the 16:9 screen share window and I could scale/resize it by dragging corners but that option is gone.
Anyone know how to get that old 1920x1080 resolution back in my screen-shared windows?

Ok so the solution was to user a different VNC client in Ubuntu. "Vinagre" allows you to view your remote session scaled to any size you like. It will however retain the dimentions of your MacBook screen.
One thing to be aware of is that when authentication your VNC session (entering your username and password) Vinagre only allows you to enter a password of 8 characters max. So if your password is longer then 8 characters you will have to shorten it to user Vinagre... A bit annoying but at least it works.
Techy notes:
It is actially the VNC server Vino that Vinagre uses that is enforcing the password length limit. So if using an alternative client that uses Vino as it's VNC server this limit will apply for that client also.
Even though you are scaling the client session down VNC sends the host's full resolution so you will still transfer a lot of data over the network.

Screen Sharing resolution - Mavericks

I am remoting into my MacBook Pro from an Ubuntu VNC client. The screens I have are much lower resolution then my retina display so the VNC session window is enormous. Is there any way I can reduce the resolution for remote screen management or perhaps use a client that allows the window session window in Ubuntu to be scaled so I can view the entire retina desktop on one screen?

Screen Sharing issues MacBook Pro Retina

Loving my brand spanking new MacBook Pro Retina 15" running Mavericks. Display set to 1900x1200. The only thing it doesn't do, is play full screen YouTube video from my Mac Mini (2011), as soon as I put that in full screen mode on the Mini. Mouse and keyboard no longer respond, the only option is to wait untill it is finished or use the controls on the Mini. My screen sharing is set to all adaptive settings.
What I have done to do checks:
remote control MacBook Pro Retina from Mini (same settings for screen sharing, resolution on Mini is 1080p) and play full screen HD YouTube video: no issues, scaling works flawlessly;
check all network settings on both computer - no issues, both connecting full speed (400mpbs), wireless file exchange proves this;
reinstalled Mavericks both on the macbook and Mini;
removed all plists and preferences on both machines;
saved files to external HD, emptied harddrives, and clean installed Mavericks on both(!) computers
Installed all updates to december 12th 2013 (including the december screen sharing update).
All to no avail. So I figured to draw some new variables in the equasion and do some control testing.
I have done a test from an older MacBook Pro 17" (2010), display set to 1900x1200 as well. No problem at all controlling either computer. Scaling works flawlessly. Dito from an older iMac 21" running Mountain Lion. Like a charm, correctly scaling to meet the screen and network confitions.
So I figured shrinking the size of the application window on the MacBook to about 1/4 of the surface, and guess what: there she flies. Enlarging the application window on the MacBook Pro has a linear effect on the responsiveness of the screen sharing application, trying to view full screen video the Mini.
Verified this by controlling the older MacBook Pro 17" (1920x1200) from the MacBook Pro Retina 15". Confirmed that the above problems persist. Shrinking the screen again smoothens things out.
This quite definite to me, it is the screen sharing application that is not able to handle scaling on the hardware or interact with the software drivers of the Intel Iris Pro/NVidia GeForce GT750M combo. I hope this gets fixed soon!!

Setting Low Res on the apps didn't seem to help, however (as has been mentioned elsewhere) changing the display settings to non-HDPI does fix it, for GoToMeeting at least. (Also it let's you appreciate how nice the retina display is, in case you've already gotten used to it!)
You need an app for that however. SetResX from http://www.sendspace.com/file/mef6sk works well for me. To return to nice Retina/HDPI mode you have to go back to Display Preferences (and the "Show in Menu Bar" option for Display Preferences is sadly AWOL in Retina/Lion so you have to navigate through System Preferences.)

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 (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.

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.

Screen Sharing Screen Resolution

I use Screen Sharing to control my headless Mac Mini with my 17" MBP. With previous versions of OSX I could get a large screen view, but now I am constained to 1280x1024. How can I improve this?

Can I display EyeTV's live TV over HDMI-out and be able to see my desktop using screen-sharing on a headless mac-mini used as a media-box?

Hi,
I'm thinking of buying a new mac-mini to replace my current one which acts as an iTunes server and records TV programs using eyeTV. I connect using screen-sharing/VNC to be able to do stuff on it (like handbrake etc.)
I have eyeTV with a satelite receiver and I want to change the setup so that:
- the new mac-mini continues to work as an iTunes server (and handbrake workhorse)
- I can use the HDMI output (inc. audio) to show eyeTV's live TV full-screen app
- I can connect using screen-sharing/VNC to the mac-mini and see my normal desktop to be able to maintain it etc. but this is a headless display (no screen is connected to the display-port).
- recorded media I'd play through the appleTV2 still + rentals etc. unless anyone knows if eyeTV software can offer up iTunes content? I don't like the eyeTV recordings in general as it seems very slow to me for access when there are lots of recordings and wouldn't be available in other apleTVs in the house AFAIK.
The main benefit that this gives me is that I'd no longer need a seperate satelite box to watch live TV and can add more eyeTV hardware to get additional TV channels all through the same HUD on the TV for ease of access.
Does this seem possible in theory & practice (ie are there any gotcha's to consider?)
- can I force the HDMI output resolution to 1080i as I go via an amp to the TV and the appleTV2 drops to low-res in this configuration so I have had to find a workaround for that.
- does the mac-mini have IR input that can be programmed?
- Does eyeTV software remain stable for long periods?
- Does the HDMI out have any handshake issues that would need a reset of the display (somehow)?
thanks in advance for any thoughts/contributions
Lee

I think the easiest way to do this is to have the EyeTV app running in one user account and sent via HDMI to the TV, and use a separate user account for Screen Sharing. Both logins can be active at the same time and with Lion you can connect via screen sharing to which ever login you need.
With regards to the Mac video resolution changing, when it is not the current input on your AV receiver. This is 'normal', if the Mac sees no signal it drops down the a lower level. What you need is to buy a HDMI Detective Plus which tricks the Mac in to always seeing a signal and hence it will not drop down the resolution. See http://www.gefen.com/kvm/dproduct.jsp?prod_id=8005
The Mac mini does have an IR receiver. This can be used with the EyeTV app, iTunes, and similar. Yes I believe EyeTV would run for prolonged periods quite happily, it is has been around for a long time and had most of the rough edges polished off. However one issue you will have to deal with is that it does not automatically update its program guide data. For this you might have to write or modify an AppleScript. Elgato support or their user forums will be a lot of help.
You can set EyeTV to convert recordings to an iTunes (Apple TV) compatible format and then delete them from EyeTV.
The HDMI Detective should solve your handshaking problems.

Screen sharing and time machine

I have a mini without a monitor. I also have a 17" G4 PowerBook. Both are running Leopard. I use screen sharing to control the mini from the PowerBook.
When I open Time Machine on the mini the screen sharing goes all white... Is this because all the nifty graphics in the Time Machine app are too much for screen sharing to handle?

What screen resolution has your headless machine defaulted to ? Since you can get in via screen sharing, see what it's defaulted to.
Consider that TM probably has a required resolution (like, Workgroup Manager requires 1024x768 minimum).
If you need to have the resolution default to a different setting on reboot, try this that I put together:
http://www.afp548.com/article.php?story=20070211165654615
It's not my work just easy-to-use packaging of existing software (read the article).
It's Universal and there's a link there for a double-clickable installer.
For those bemoaning their experience jumping ahead with 10.5 server in a production environment:
well, that's your doing. Did you do full pre-testing in a non-production setting and confirm for yourself that it's ready for your needs ?
If you think 10.4.0 was perfect you are living in a fantasy. 10.4 server was a very rocky road til around 10.4.3 and there were still many fixes needed that came with later revisions.
10.3 had plenty of problems (!!) and 10.2 was a beast til 10.2.8 and I don't miss it.

How to set Screen Sharing to greyscale on Leopard 10.5

The new screen sharing feature (just a built in VNC client) is decent, although I would've liked it better if it gave an option to view the connected computer in greyscale (like Apple Remote Desktop can), so as to make the screen redrawing much quicker. This is how you do that:
To change this setting manually, open up the Terminal and type in the following command:
defaults write com.apple.ScreenSharing controlObserveQuality 2
This changes the controlObserveQuality setting within this plist file: “~/Library/Preferences/com.apple.ScreenSharing.plist” file to 2, which is grey scale. To change it to a different resolution, substitute the number 2 with one of the following numbers:
1 = black and white
2 = grey scale
3 = 8 bit color
4 = 16 bit color
5 = full color
However, when you've connected and you're all happy that you have greyscale, if you then choose Adaptive Quality from the View menu in Screen Sharing, this will set the default back to 3 (8 bit color), and you'll have to run the Terminal command or edit the .plist file again - so, just leave it when you initially set it and all will be well!

I tried the malisphoto.com solution it but it didn't work for me.
I even tried the one at entropy.com but that also didn't work.
I was very careful and successful in the command line (bash) and afterwards, phpInfo() showed that the GD library was installed, however, my localhost GD (gif draw) scripts still kept showing the same old error messages on my localhost (and not online): "Fatal error: Call to undefined function imagecreatefromgif()"
Perhaps I'm just wrong to think PHP GD will work on my localhost pages after performing these installations - perhaps I'm misunderstanding something? Am I'm trying to change a light-bulb with a jack-hammer?
I should also point out that both solutions made my localhost run extremely slow. After restoring my system, it's all working fine (but without php GD).
My system is a Power Mac 10.5.8 Leopard
This is really lame. Is Apple trying to shut out PHP now? Is PHP the new "Flash"?

Screen Sharing

I have two computers, a dual quad core 2.93 GHz MacPro equipped with 24 GB of RAM and 2.5GHz Core 2 Duo MacBook Pro equipped with 4 GB of RAM. Both computers are running OS 10.6.8. The two computers are connected via DLink Gigabit Ethernet switch and have been assigned static IP addresses. Originally I had an Apple 23" Cinema Display attached to the Mac Pro and was easily able to use Screen Sharing whenever I wished. Recently I acquired a Samsung Syncmaster Model S27A850D 27" monitor with a resolution of 2560 X 1440. The Samsung monitor is attached to the MacBook Pro. However, when I attempt to induce screen sharing using the screensharing application on the MacBook Pro, I get a dialog box stating that it is "connecting to the correct IP address but never connects.If I connect by double clicking on the MacPro under "Shared" I am presented with all hard drives connected to the MacPro and all home folders. I can access all documents on the MacPro. nWhile for many purposes a simple KVM switch allowing me to use one keyboard and mouse with both computers would be sufficient, there are situations where screen sharing would be helpful. I simply don't understand why it has ceased to work. Interestingly enough, if I attempt to invoke screen sharing from the MacPro, it does work after a fashion although because of the difference in resolution the screen is a mess. Anywone with an idea of how to solve this problem? Thanks in advance

Thanks rgman
Unfortunately following these directions - - which I'd already done, did not help. Still get an endless the "Connecting to "IP address" dialog box. So I can't share screens at the moment - - although as I noted earlier, it was no problem prior to installing the new Samsung monitor. I may try reversing the monitor/computer connections to see if have any etter luck, but that still won't be the setup I want to have.

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.

Messages Screen Sharing Ends with a "Hanging" Desktop Screen

Since the OS X 10.8.1 update, Messages screen sharing – that used to work well in my environment – everytime ends up with a hanging desktop screen. That means: The screen of the desktop, where Messages screen sharing took place, freezes. I have to swipe to another desktop in order to successfully quit Messages via the dock context menu. After that, its desktop screen is responsive again.
This happens independant of who ends the screen sharing session.
It used to work seemlessly before OS X 10.8.1. So I think there is an issue with this update, Messages and the screens (desktops) management.

Hi,
As Screen Sharing does tend to involve a change from the Shared Screen at one resolution changing to your screen at possibly another (which for some produces the White Screen In Sharing) I thought it might pay to look at the method when wanting to go back to your own screen during a Screen Sharing Chat
I would still report it here
http://www.apple.com/feedback/ichat.html
Obviously you have to use some of the free text area to state your OS version and Messages version at it will not appears in any of the drop downs.

Unable to resize Screen Sharing screen

Hi,
I am seeing two issues with Screen Sharing when accessing a desktop Mac from a MacBook Pro with a 20in external monitor attached to the laptop.
Using the Screen Sharing application to remotely control the Mac Pro when I connect the size of the Screen Sharing window varies, most of the time it is small (about half screen width and two thirds screen height) but sometimes it is almost full size on the monitor. The Fit Screen in Window button setting does not seem to affect this.
Furthermore when I try and drag the bottom right hand corner to increase the size of the Screen Sharing window it will not allow the window size to be increased.
In 10.5 Leopard the Screen Sharing app could be configured using defaults but Apple in their, err, wisdom, have disabled them it seems in 10.6 Snow Leopard. So...
(1) Is there any way to make/configure the app to always display a maximized screen size when connecting to a remote Mac?
(2) Why can I not resize the window by dragging the right corner using the standard Mac window resizing mechanism?
Thanks.
Tim

Try playing around with the window positioning. There is no definite way to keep a window's size/position, but try playing around with it.
I have dragged the window around but it makes no difference.
(2) Why can I not resize the window by dragging the right corner using the standard Mac window resizing mechanism?
You may not be able to make it bigger, but can you make it smaller?
Yes I can make it smaller but when I drag to make larger again it stops at the original size and you cannot drag further.
I noted that the screen resolution setting in the monitors preference pane of the Mac Pro had been set at 800 x 600 but it was set to 1680 x 1050 (the res of the 20in monitor) so perhaps Screen Sharing does not support that res and it gets reset when you create the connection?
