Dual-Display Issue: Mavericks selects primary screen randomly

I am using to Displays with my Mac Pro connected with 2 internal graphic-cards (2 original mac specific GT 120 ounted at PCIe Slot 1 and Slot 3). It worked like a charme till i updated to Mavericks.
Currently on every system-(re)start the primary screen is swapped/selected randomly. Sometims the left one, sometimes the right one is primary. No matter the display settings i made.
I need a solution for this.
Best regards
Volker
Btw:
When will colors come back to Mac OS? Everythings grey and colorless since Lion. Imho a usability setback. Especially the Finder could benefit of some colored Icons again.

This has been happening to me regularly since buying one of the new mid-2009 MacBook Pros. It had never happened with my previous early-2008 MacBook Pro.
Additionally, the detect displays functionality is not triggered as it should be by dis/connecting the display. I have to manually “detect displays“ every time. Very frustrating, and pretty weird.

    How do I use dual displays to have a full screen app on one monitor and another full screen app or the desktop on the other?
    I want to have my itunes visualizer on my TV which is connected via HDMI adapter, and still have access to full screen itunes and my desktop on the main display.
    Any suggestions?  App downloads that can do this?  Please let me know.

    You can't do it.  This has been an issue since Lion.

  • Intermittent Dual Display Issue - Random "Detect Displays"?

    Have an MBP w/ Samsung SyncMaster T220, attached via DVI. In recent week, or so, the two monitors will 'fade to blue' (like it will if you attach another display while the MBP is already up an running) then return back to 'normal' as if nothing has happened. When this happens it may stay on the 'blue background' for a split second, or for up to five seconds.
    It is as if it 'looses' the dual display then gains it back. And the 'blue screen' seems the equivalent of "Detect Displays" being randomly instantiated.
    [NOTE: the 'blue screen' is not the screen of death nor does the MBP lock up. In fact, as I've typed in this posting, it has happened approx. six times, I can keep typing and when the screen returns the stuff I typed in while the screen is blue is all there.)
    I've checked the cables, the connectors, the power sources, etc.
    Thoughts?

  • Cisco Profile 52/55 Dual - displays video on only one screen after software upgrade 7.1.4

    Hi,
    I've upgraded the Profile 52/55 Dual system to TC 7.1.4 and it no longer shows video on both screens during a conference. It displays content on the second screen fine. It worked in version 6 so I wonder if something changed in the software or the endpoint requires some additional configuration.
    I've checked settings under Configuration > System Configuration > Video > Monitors and it's set to Dual. I've changed it few times and set it back to Dual but this didn't resolve the issue. I can't see any dual screen option key added under system information but I assume it has a dual screen option hence it's a dual screen system.
    Do I need to change any settings?

    Hi Patrick
    Thank you very much for your response.
    The system doesn’t have a remote control as such, it’s an MX700 so it has the 10inch touch panel, I had some engineers onsite attempting to bring the self-view image up using the panel but the only image that they managed to retrieve was a self-view PIP on the main image.
    If I change the self-view settings in the configuration nothing appears to happen on the codec, the second monitor will only display the presentation, it’s as if the system is stuck in dual screen presentation only, even though when I set the system to dual screen, flick it back to single screen, set it to dual screen, back to the same situation no image unless there is a presentation being sent.
    I have ensured that these settings are forced on the system
    xconfig Video Monitors: Dual
    xconfig Video CamCtrlPip CallSetup Mode: Off
    xconfig Video SelfviewDefault Mode: Off
    xconfig Video SelfviewDefault OnMonitorRole: Second
    xconfig Video SelfviewDefault FullscreenMode: On
    But no matter what I do I am unable to get the behaviour that I expect, this is why I have posted on this forum, I seem to think that the problem may be related to a software bug, however I am unable to downgrade as that would stop the control panel from working (this system doesn’t have a remote), and I see no mention of a second monitor issue reading the release notes, I have checked the online bugs and cannot find anything there either. so I am wondering if someone in Cisco has any idea as to what is happening here.
    I thought about trying to use TC console to see if I could force a layout via this tool / or at least see what layouts are on the system, however the TC console version 6 will not connect to this system (I think this is more firewall related than system, as standard telnet and ssh attempts fail also).
    Again I appreciate any and all assistance provided greatly, I am completely baffled as to what is happening here.
    Cheers

  • Lightroom 4 (beta and current release) - Issue with Select Catalog screen - catalogs not displaying

    I noticed this during the beta test version of LR4 and was hoping it would be corrected in the actual release (which I installed yesterday).  Here's the issue:
    When the Select Catalog window opens, catalogs will not display unless I click in the empty space in the window (first screenshot)...then they will appear one by one as I start to click (second screenshot) until all are displayed.
    Does anyone have any suggestions??  These catalogs are NOT on a network drive, they are on my desktop machine (Win Vista 64-bit).

    I have the identical problem.
    LR3 worked perfectly. LR4 won't refresh the Catalog screen at startup without me clicking on each entry. Only when an entry is selected will it appear.
    I have an nvidia GeForce 9800GT video card, supporting dual monitors.
    I'm using Vista 64.
    I just upgraded to LR4 64bit, and immediately had this problem.
    I installed the most current video driver (2/12/2012) with no change in problem (or performance).
    I have not noticed any other program having issues, and have not changed any hardware recently.
    I am also noticing that LR4 is visibly slower than LR3, to the point where most sliders don't slide evenly, but jump in increments unless I move VERY slowly.
    I've watched the processor load using resource monitor: it is not peaking over about 65% during slider actvitivity.
    I have an Intel Core2 Quad CPU Q9550 @ 2.83GHz with 8 gb of ram.

    Hello wmbell247,
    It sounds like you are getting some graphical anomolies after updating to Mac OS X Mavericks. I recommend these troubleshooting steps from the following article named:
    Apple computers: Troubleshooting issues with video on internal or external displays
    http://support.apple.com/kb/ht1573
    Reset the system
    You can reset the Mac's parameter RAM and SMC.
    Reset the resolution
    Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.
    Also you can test the issue in Safe Mode, which the article references and see if the issue happens there. If not then a 3rd party login item may be causing an issue with the system:
    OS X Mavericks: If you think you have incompatible login items

    Thank you for using Apple Support Communities.
    Take care,

    Phirefenix,
    Welcome to the discussions. First question: are you sure it is a Mac compatible video card? If not, the second comment will not work.
    During startup, after the studio display lights up but before the software starts to load, hit the reset button on the front of the computer. This will give what I call a 'warm boot' and eliminate some esoteric issues. If that works, buy a new PRAM battery. If that does not work, verify question one.

    Version: 10.6.8
    Build:10K549
    I have a iLuv Mini DisplayPort Cable, a 9-Pin to 9-Pin Firewire Cable, a M/M USB Cable and an ethernet cable.  What I have been trying to do is link these two computers together so that each can be used as a seperate processor but their screens can be shared.  Before anyone tells me this is impossible, these two monitors have in the past been connected together so there was the ability to dual use the computer monitors.  I do not remember if I actually had the processing power of both available.  When I plug the minidisplay port cable from one computer to the other the screen on Machine 2 will blink black to blue and then go back to an independent screen.  The displays tab on neither computer shows two displays and none of the command f2 or f3 prompts are causing either computer to respond.  I have tried connecting them with firewire and USB and can only get disk transfer mode from the Firewire.  I know these computers used to be able to support being connected to one another and now I have no idea what is going on.  I don't personally remember having a minidisplay port cable in the beginning so its possible I am going about this all wrong.  I have called Apple Support many times and they suggested an OSX reinstall.  I found the reinstallation software for 10.6.3 for a macbook 13 inch and each computer recognized the disc but said that the operating system could not be installed.  At this point I have done everything I can think of including running a hardware test through the diagnostic tool at startup and on both computers the test came up with no error codes.  Please please help me get these computers working again for my boss!

    Both the 9,1 (Early 2009) and 10,1 (Late 2009) iMac's only support Target Disk Mode using FireWire.
    see > Target Disk Mode vs. FireWire networking | Macworld
    or > Apple Tips Using Target Disk Mode
    Adding that if the Late 2009 is a 27" then it supports Mini DisplayPort input for use as a monitor from another Mini DisplayPort Mac.
    see > iMac: How to use your iMac as a Target Display Mode display
    An Ethernet cable can be used for Networking and File Sharing the two iMac's.
    see > Mac Basics: File Sharing
    Plus connecting two iMac's together with a USB cable, will do nothing except trip the USB port overloads or something worse.

  • Has anyone else had the issue of the the screen randomly flashing black only when using Messages app in landscape?

    I have been having an issue with the screen flashing black for several seconds then turning back on. This olny occurs in the Messages app and only in landscape mode. I have never noticed the issue in any other app. The issue is 100% repeatable. Has anyone else had this issue or know of any solutions to what seems to be a bug?

    I think this is an issue with the phone's proximity sensor (the one that turns the screen off when you hold it up to your ear). It's a bug that seems to occur when you switch to another app (any app) while still on a phone call. You'll notice in Messages that the screen goes dark when you move your thumb over the earpiece/iSight camera, but not when you move your other thumb.
    Simplest solution is to force-quit the Messages app (double-click the home button, and swipe up on the app). The problem should resolve itself when you restart Messages.

  • Ps4 display issue black and white screen

    Hi,
    So to cut it short I was watching TV fine before. PS4 was fine when I switched it off last night.I turn it on this morning to no colour in the picture. I've checked the TV settings, switched all hdmi related. Reset in safe mode display and default settings changed the HDMI lead even switched TV same issue.
    I'm starting to think it's definitely a machine issue. I hope it's something simple because it's barely over a year old.
    Help please someone

    Didnt need to go through the Initialisation, Simply disconnected the power of ps4 and Bravia Tv and connected them back on after 10 Mins. Temporarily lost hdcp features but probably thats why it worked. 

  • Cinnamon dual display issue

    I have a perfectly working setup with KDE and I decided to try adding cinnamon to give it a try.  I added the cinnamon package, switched to slim rather than KDM as my display manager, that all works fine, I can log into a cinnamon session no problem and everything seems to work great, it's nice and fast.  However, I get the following error when trying to use the cinnamon control panel to set up my displays.
    cinnamon GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface 'org.cinnamon.SettingsDaemon.XRANDR_2' on object at path /org/cinnamon/SettingsDaemon/XRANDR
    I'm using intel onboard graphics with xf86-video-intel drivers.  SNA rendering with tearfree enabled, with by the book settings from the wiki.  I can't seem to find anything googling this issue other than a few ubuntu references that don't apply to my situation.
    I can set multi monitors up from the console using xrandr no problem.  And the KDE display applet works fine over in KDE.  But I'd like to get the built in cinnamon controls working, so has anyone experienced this?

    That is the issue...I cannot get into the ACER menu as it stays in sleep mode...I have tried powering off and on again and it says "no signal" and goes into sleep mode.

  • Lightroom & dual display issue

    I have a MacBook Pro and an external NEC MultiSync monitor. I'm running on the latest Version of Yosemite. I keep my MacBook Pro as home base so to speak and the external monitor secondary. i used to be able to keep Lightroom as a floating window and that feature seems to have disappeared. What is really frustrating is that if I make the wrong move with my mouse Lightroom winds up on the other monitor. Sometimes I can get it to return with a mouse click on my laptop but not always, So then I have to quit lightroom and start over. this may be considered an Apple issue but I away have this problem with Lightroom. I've had it with both versions 5 and now 6. Anyone know the right way to deal with this.

    What I do is I open up the main Lightroom panel on my MacBook Pro and then I open the secondary display on my NEC monitor. and use it in the loupe function when I get down to doing critical work and adjusting exposure. The problem with the laptop monitor is that viewing angle is critical. What was frustrating for me was not being able to use Lightroom as a floating window. Started out that way and then with the wrong keystrokes I lost that ability and then what would happen is that if I tapped my mouse or did something wrong way on the second monitor the Lightroom panel would switch to the second monitor but I wouldn’t be able to access the drop-down menus and occasionally I could get it to switch back when I found myself rebooting more often than I care to mention. And then I couldn’t access my doc file if Lightroom was the active app. so it’s been a pain in the butt when you told me has been a big help so thanks

  • Dual Display issues with Mac Pro 1,1

    I am running two 19 inch displays, the main display works fine but the second display comes up black. The computer recognizes both displays and I can change the settings but no image will appear on the second monitor. Now, It seems to always think there are two diplays connected even after I disconnect the second monitor. I have a MacPro 1,1 2.66GHz with the Nvidia 7300 Gt Video Card.

    Why not send the 7300GT to the shelf and give it a rest, time for ATI 5770 after all this time, which can be found on Apple Store $249.
    Might want to inspect the 7300 for damage, dust, (whole case) and of course temps.

  • Dual Display Problems - No Signal After Sleep

    So, I just set up my hexacore Mac Pro with stock ram and the ATi 5870. To go along with it, I purchased two Dell U2311H monitors from Dell so that I could finally have dual displays. I then purchased two 6' minidisplayport to displayport cables from Monoprice. Also went with the Apple wireless keyboard and Magic Mouse.
    Upon initial start-up, everything worked fine. The monitors needed to be calibrated, but dual display mode worked perfectly without any extra steps. I had some fun messing around for a little bit and then decided to take a break. I put the computer to sleep.
    I came back 15 minutes later (couldn't stay away for long), and clicked the mouse to wake the computer back up. I heard the tower humming, but the monitors stayed black. I tapped the keyboard. Still black. Assuming it was some issue I wasn't prepared for with the wireless peripherals, I futzed around with them for a while and had no luck. Still not image on the monitors. I turned the monitors off and then back on only to get an error message explaining that the monitor was in Power Save mode. Some further exploration revealed that the monitors were allegedly getting NO SIGNAL from the computer.
    Restarting didn't help any. The only thing that has "worked" is shutting down the computer and connecting a single monitor through the DVI-D cable that came with it. I can then reconnect the displayport cable and switch the input to re-establish dual displays, but this is obviously pretty annoying. It seems like I can eliminate questions with the monitors themselves or the cables. In doing some research, I've found some threads on different sites about people having similar dual display issues attributed to faulty graphics cards. I certainly hope this isn't the case, but I'm at a loss for what the problem might be. It seems odd that dual displays would work briefly only to fail after going to sleep for 15 minutes.
    Sorry if this is the dumbest question ever. Is there something stupid that I'm doing wrong? Anyone have any insight?
    Any guidance you guys can provide would be greatly appreciated. Thanks in advance!

    I have the exact same issue. Here's the forum I've got going: http://discussions.apple.com/thread.jspa?threadID=2686085&tstart=90
    I called AppleCare because this issue was out of the box. Engineering wanted to capture some logger information so I ran the logger and sent it off to them.
    I am running a Dell 27" via a DisplayPort to Mini-DisplayPort cable (also purchased through Monoprice) and a Dell 22" via DVI to DVI (have also tried with the DVI to DVI cable connected to an Apple DVI-MiniDisplayPort adapter and the same issue arrises). When I boot the computer with any of these cables, I get no video. Only when I boot with a Dual-Link DVI (DVI-D) cable from the 27" monitor do I get any video on screen. At this point, I can then plug in the DisplayPort to Mini-DisplayPort cable and the regular DVI (not Dual-Link) after unplugging the DVI-D cable and I get video. If I restart the computer, no problem. However, if the computer goes to sleep or if I power down and then power back up, I am back to square one with no video and have to resort to using the Dual-Link DVI cable.
    Because this was DOA out of the box, they ended up just RMA'ing the machine and re-ordering my CTO Mac Pro 6-core. Still waiting for it to be built, I'll let you know how it goes on the second machine when it arrives.

  • Mac Pro Display Issue

    Mac Pro Display Issue - Unexpectedly Sleeps and Freezes
    Just since a couple of days my Mac Pro desktop has been having display issues. Unexpectedly the screens go into sleep mode, it turns black and freezes, the computer doesnot respond to the keyboard or mouse.
    At first I thought this was related to Chrome, and switched to Firefox, but the computer is still having the same issue. I have to shut down and restart each time it gets stuck.
    I even went into preferences and changed the energy saver settings to "Never" allow display or harddrive to sleep. But this problem is stil happening.
    Does anyone have the same problems? Or a solution?

    I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
    So I followed your advice and installed:
    Temperature Monitor
    http://www.bresink.de/osx/TemperatureMonitor.html
    Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.
    Then I installed:
    smc fan controller
    http://www.macupdate.com/app/mac/23049/smcfancontrol
    and increased the memory_cpu fan speed which lowered the temperature of the ram to 60'C (143'F).
    I even changed this ram's placement and put it in different slots.This ram was the same temperature in the new placements.
    Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
    Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
    Thank you for all your help!
