Screen sharing shows a second display

I have installed a graphics card in my Xserve G5, an ATI Radeon 9200, with a monitor attached with the DVI-cable. When I use Screen Sharing or ARD, then it shows two monitors, the second (without the monitor) being of a lower resolution. I have tried to mirror these, but then I only get the lower resolution. How do I get rid of the fake second display? Once a window gets over there, then I have to use Screen Sharing to relocate it and place it back on the real monitor. Frustrating.

Hi,
Change the resolution on the Older OS.
It is the only workaround we have found at the moment.

Why doesn't Screen Sharing work across multiple displays anymore in Mavericks?

Hey Guys,
I'm having a problem with Screen Sharing in Mavericks. It wasn't a problem in Mountain Lion, so I'm wondering if you could help me.
I use a Mac Pro with multiple displays to connect to another Mac Pro with multiple displays. Here's how it looks at first:
Two remote desktops shown in one window on one display locally. (Note: there are two different displays connected to this Mac Pro.)
In Mountain Lion, I used to be able to scale this up across displays. When I do that now, the remote desktop scales down to the lower-left corner. Observe:
When I mouse over it, there's some screen tearing (artifacts):
Any ideas?
Notes:
Yes, I've Google'd it.
I don't have Mavericks' multi-display support enabled. I disabled it to spread out Avid Media Composer and Adobe After Effects usage.
Thank you,
Isaac T.

Screen Sharing shows red screen

Hello, I connect to several machines via Screen Sharing. All work fine except one, a mini that is at a hosting center. When I log into it the screen is red. Like everything has a red filter over it. If I reboot the mini the login screen is fine but after it's logged in again the red returns.
Anyone know what would cause this or how to get rid of it? Thanks.
I am using OS 10.5.6 and the mini is 10.4.11.

I'm having a similar problem: When trying to sync my iPod or iPhone the screen turns red (however, it's more similar to the acid filter on some photo editing software or the pop-art filter in photo booth). I'm having a new iMac and the newest updates.

Screen Sharing (10.6 viewing 10.5) shows a screen of horizontal lines

I use Screen Sharing 1.1.1 on 10.6.4 to access my iBook G4 and my wife's Power Mac G4 (both running 10.5.8).
A week ago I attempted to view the G4 screen. Instead of the normal display, Screen Sharing showed a screen of colored horizontal lines of varying heights. There were a few random blocks with different color lines. Nothing on the screen was recognizable.
The same display problem just occurred with an iChat screen sharing session (iChat 5.0.3 viewing iChat 4.0.8 on the G4). Restarting the G4 cleared up the problem.
My search of Apple Discussions has not turned up a report of this problem.

Hi,
I have not seen this either.
I have 10.5.8 on my G4 and a MacBook Pro running Snow Leopard.
I have heard of issues and can recreate them if my G4 has a second Monitor/screen connected and Mirroring is not On as the iChat Screen Share tries to fit both on to the Shared view (i.e two Screens wide instead of only one.)
I presume the Screen Sharing app would be the same.
Do the G4 users have the Screen Zoomed or any other option set in Universal Access ?
Does changing the resolution in System Preferences > Displays change anything ?

Screen sharing only in one way

Hi, I'm doing screen sharing everyday -mostly for helping other with their macs- with no problem but with one person (an uncle of mine).
He uses a new 20" iMac (the late one), we can text chat, videoconferencing, audioconferencing and screen sharing in one way, I can let him control my mac but it's impossible to let me control his Mac.
The fourth button in ichat (where to ask for permission or give permission to screen sharing) is half enable, only one of the options is enabled to click on, the option for "ask for screen sharing" isn't. So I can give him permission to control my mac but not to control his mac.
How can this be possible? I asume screen sharing works in the same protocols in both ways, above all when we can do video and audio conferencing.
Thanks in advance for your help

Hi Ralph,
When you have ticked the screen sharing option in iChat>video>screen sharing and your buddy "high lights" (one click) your screen name the screen sharing icon will be displayed in black on his end indicating "enabled".
This way he can ask for your permission to share your screen.
When your contact has not ticked the screen sharing option the screen sharing icon in your contact list will be grey.
When your contact has ticked the screen sharing option as well the screen sharing icon in your contact list will be black as well.
Of course all other requirements for iChat screen sharing have to be met.
More important: I wish you a very happy new year!

Screen Sharing not working from Yosemite 10.10.2 = Mavericks

Seemingly after the upgrade from 10.10.1 to 10.10.2 my workstation can no longer connect to the workstations that I had successfully before been connecting to before the upgrade. I have already tried formatting my hard drive and transferring files from a previous Time Machine backup.
From the terminal if I issue this command:
open vnc://192.168.1.201
Below you can find the relevant logging to /var/log/system.log (including leading and trailing logs for potentialy relevance)
http://tny.cz/69b303b6
I can succesfully connect to that URL from a machine running mavericks version 10.9.4 on the same wireless network.
Clearly something is crashing on the newer Yosemite machine – potentially relevant lines are:
"Screen Sharing[309]: No valid display name"
"acquire_kerberos failed com.apple.idms.appleid.prd"
"-[SSAddress url]: unrecognized selector sent to instance 0x7fad60e77510"
Another thing to note is that I can only perform that operation one time and achieve that stacktrace. Every other time I issue that command Screen Sharing.app fails silently.
Thanks!
James

Hi Bill,
You could try removing all the installed components manually and then try again (install, don't open but update right away).
According to the installer the files are located in:
/Applications/Remote Desktop.app (that one was hard to find )
/Library/Application Support/Apple/Remote Desktop/
/Library/Preferences/com.Apple.ARDAgent.plist
/Library/Preferences/com.Apple.RemoteDesktop.plist
/Library/Receipts/
/Library/Widgets/RemoteDesktop.wdgt
(not sure if the following files tie into other parts of the OS so removing them may cause issues)
/System/Library/CoreServices/RemoteManagement
/usr/bin/share/man/man1
perhaps a permission repair after all parts have been deleted and a restart before trying again.

IMac 11.3 as second display in Maverick, just shows a black screen

I'm trying to reuse my iMac 11.3 mid 2010 (ATI HD 5750) as second display for my MacPro 1.1 (ATI HD5770 + 24" Cinema) through a mini display cable. This used to work fine in 10.8. Now both computers are upgraded to 10.9 and iMac only shows a black screen when pressing Cmd+F2 on the iMac.
Any hints appreciated besides this is only supported for +2011 models

Yes I agree it is something wrong with Safari, but WHAT?
I have two macs sitting beside each other, both running Safari pointed at a .pdf file; one runs adobe just fine, the other shows black.
No amount of pawing through the Preferences tree shows me anything remotely relevant.

Screen sharing and dual displays

Hi, i added a second display on an iMac and often screen share using my MacBook but since adding the second screen i've had issues screen sharing. It will briefly show both the iMac's displays on my MacBook but then cut out with "connection lost", then find the connection again, then lose it etc etc. Sometimes i can select just the first display and it'll be fine but usually the connection keeps dropping and firing up so quickly that i can't get it to just show the one screen.
I unplugged the second display and everything worked fine as it always has done. Is this a known issue to be resolved in 10.5.3? If not is there a way i can change the default in screen sharing so that it'll just show me the first display? I don't need to see the second display particularly so that doesn't bother me.
Thanks, Simon

It may or may not be a common problem, since I screen share a 2-screen Mac Pro from a MacBook Pro and have not seen this problem. I always get both screens.

Screen Sharing issues with ML and SL with dual displays??

Don't know if this is a ML issue or was present in Lion (which I never upgraded to)
Setup...
Old setup was 2010ish MBP and only 2006 iMac. Both with SL 10.6.8 and both have two monitors...no issues.
Upgraded to ML on the MBP on release. Realtively painless process. I tried screen sharing today and I get odd responses with the MBP to the iMac. Just so everyone knows, screen 1 is the main iMac screen and screen 2 is the additional monitor. When showing both screens I could see all screen realestate. However, when I changed to only display screen 1 I started having issues. I couldn't get the entire screen to fit within the window nor scroll to show areas not displayed. Sometimes switching between fit in window and no fit, I would get a blank screen. Screen 2 only displayed and all is fine. I noticed on screen 1 that there was a little black bar or open space on the bottom of the window that was exactly the same size that was missing from the top. No ability to fit or scroll would allow the black space to move so that the menu bar on the top of the main monitor would display.
After doing a bit of searching with no luck and scratching my head, I took a look at the Arrangement screen in the display settings. Wouldn't you know it that the main screen (having a smaller resolution than screen 2) was aligned so that the top of each display was even with each other leaving a small space on the bottom of screen 1 compared to screen 2. When I moved screen 1 in the arrangement screen to a more drastic alignment to verify this was the problem...screen sharing crashed when going from both screens to only display screen 1. Tried screen sharing again going from two displays to one, crashed again.
It appears there is some sort of bug or maybe ML and SL screen sharing doesn't like each other when the remote computer has two monitors.
Submitting bug report to Apple but was curious if anyone else has seen this or knows a work around.
Mike

I have a similar configuration (Lion 2011 MBP and SL 2009 iMac w/ second display). After installing the recent Remote Desktop update things went awry when trying to share the iMac SL displays with the MPB Lion.
The displays on the iMac are the same resolution, however the second display physically sits a bit lower than the iMac display, so I had adjusted the arrangement to compensate the different heights. The second display is located physically to the left of the iMac display, but that shouldn't have any effect as far as I'm concerned. Screen sharing had worked in this config until the recent Remote Desktop update (on Lion).
I thought about what you mentioned about the display screen arrangement, so I decided to just test it for myself, arranging both displays side-by-side on the displays arrangement control panel. Surprisingly, it worked!
I do consider the Remote Desktop update to be the culprit and there must be some bug associated with that. I'm getting ready to submit a bug report, so hopefully we'll see a fix soon.

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.

How to see only one of two displays in Snow Leopard Screen Sharing?

I am trying to set up screen sharing and find that since I have two monitors working on the machine that I want to connect to, two monitors show up on the client that I am connecting with. This causes a problem in that the scaled screen image that appears on my macbook pro is too hard to see and work on.
Is there a way to specify only one monitor image to appear in screen sharing?

On my Mac OS X Screen Sharing display, it has a display selection pop-up in the upper left side of the Screen Sharing display
Both Displays: 3760 x 1920
Display 1: 2560 x 1440
Display 2: 1200 x 1920

Display is not working But Through Screen Sharing I can Access my computer

Ok. After turning my computer off and then turning it back on a couple hours later the screen would not turn on. Im still able to log in. With screen Sharing I can acces my computer and system profiler shows that my RAM cards are OK. However when I click on Graphics/Display it unexpectedly quits.
What could the problem be? Any help is greatly appreciated : )
Ps. I wrote this through screen sharing out of my account on the display-less computer.

Welcome to Apple Discussions!
I wonder if you could have the NVIDIA chip problem?
http://support.apple.com/kb/TS2377
Is the display totally dead, or can you see your desktop if you shine a strong light through the apple on the back of the display? If so, you may have a different issue with just the internal display. A good test would be to see what happens with an external display connected directly to the MBP.
Good luck!

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.

Mac pro cinema display cuts out and can't access Mac with screen sharing

Hi
A weird thing has started happening to my Mac Pro today. After using it for a few minutes the cinema display it is attached to on the Mac Pro just goes black. The Mac Pro is clearly still on - the light is on and i can hear the fans. The Mac Pro shows up on my local network and i can connect to it and access files from my Macbook, but screen sharing doesn't work (i just get the message 'contacting mac pro' and nothing else) and i can't connect to shared iTunes library either, which makes me think it is not just a display issue. I cannot wake the computer with the mouse or keyboard, which makes me think it isn't just a sleep issue. All i can do is physically turn the Mac Pro off, start it up and it will start up successfully and then work for a few more minutes before i get the same problem. I have reset the PRAM and SMC and still have the same problems. Can anyone suggest anything else i can try?
I should mention that i have another problem with the Mac Pro in that it has been spontaneously waking up from sleep and starting up from shutdown, and i still haven't resolved this. I don't know if it is connected to the above issue.
thanks
nick

I have experienced almost the exact same thing with my new 2008 Mac Pro and my 30" Apple display. It has happened to me twice in the last few weeks. The first time I chalked it up to a fluke, but now that it's happened again I searched the forums. In both cases I've had music playing in iTunes which continues playing, goes on to the next track, and so on. So the machine has not crashed in full. I too can connect to the files via another computer on the network, but cannot share the screen.
I have not had the sleep issues you have had.
I'll look at the link you provided in your next post to see where that gets me, but I wanted to let you know you were not alone on this one.
