Dual displays cursor problem

I have a new Mac Pro and I had a 27" & 24" monitor connected to the card (Display Port, not Thunderbolt). Everything worked fine. I replaced the 24" with a new 27" (Display Port, not Thunderbolt) so now I have two 27" monitors.
The problem is that the mouse/trackpad cursor remains trapped on one screen and will not move to the other screen, nor can I move windows from one screen to another. Sometimes after rebooting, the cursor will appear on the other screen but will be trapped there as well.
I can't find anything useful on a search and looked for plist files to delete but couldn't find any that looked like it would help.
Any ideas how to cure this problem?
Thanks, denny
PS- Using Mountain Lion

Well, it looked right then I noticed that the white menu bar was on the wrong monitor. I dragged the one monitor to the opposite side and all is well now. What confused me was that all I had done was shut the machine down, swapped monitors and then repowered the machine. I guess I just assumed it would be OK as I've done this before and everything was OK.
Thanks for your help!

X1900 XT, dual display: sleep problems

Today I updated my Mac Pro from an NVIDIA 7300 GT with connected BenQ and Samsung displays to an ATI X1900 XT with two 23" Cinema HD Displays. Everything works fine except one thing:
When trying to put the system to sleep it wakes up again after 2 seconds and a few seconds later the fan goes to highest speed level and stays there. The only possibility to stop the system is to shut it down completely.
The keyboard/mouse are connected to the "first" display, no other USB or Firewire device is connected.
All OS X updates are installed including EFI Update 1.1
Any ideas how to locate the problem?
Thanks in advance,
Wolfgang

Sorry for the unprecise / wrong information. The problem could be solved by removing a USB smart card reader that was attached to the USB hub of the second display.
At the old display it worked fine but the combination Cinema display / Vivanco Smart Card reader produces a signal at the USB that wakes up the Mac Pro immediately. I do not have a clue why the Mac Pro speeds up the fans afterwards but this behavior can be reproduced easily with every USB device that is removed shortly after the Mac went to sleep.
The hint for this could be found in the system.log:

Another dual display problem - GeForce FX 5200

I've seen lots of questions about dual display problem, situation when trying to connect two non-apple vga displays to your graphic card.
I have GeForce FX 5200 graphic card, with 2 display output's. And two DELL 17" vga LCD displays.
I manage to connect 1 display regulary with dvi to vga converter, but for other display I tried several difrent converters ADC to DVI to VGA, and it just did NOT work.
G5 could see other display in display settings, in arrange option I coud see two identical displays, but I don't get anu picture (desktop) on other display???
Is it problem with output's on my graphic card (Gforce FX 5200), could it be soloved with some ADC to VGA converter?
P.S. Dr. Bott ADC VGA Extractor is not compatible with GeForce FX 5200????

Dual displays problem

Hi,
I just bought two new displays (2x BenQ FP222, 22" widescreen) to use with my new Mac Pro 2.66 (GeForce 7300 GT), but here's the problem: When only the first display is turned on the computer is fine, but when both displays are switched on the picture on both displays goes black every few seconds and then comes back.
I have connected both displays to the computer via 5-metres DVI-cables, which my dealer said would be ok. I understand that I only have the standard graphics card, but as far as I know that shouldn't be a problem unless I try to use dual 30 inch displays.
It sounds to me like it could be a problem with the computer not having enough power to run the two displays (they both use 1680x1050)? Or could it be a faulty DVI-cable?
Has someone got any idea what might be the problem?

Have you updated the firmware on the nvidia to the latest? Just a thought, but to your comment about powering all the cards...... the power supply will give only 5 volt for each PCI interface rail. The monitors get their power from the AC outlet. As robust of a machine the Mac Pro is, I doubt it will have any issues powerwise even if all of the slots are full. The ATI card requires an additional power cable because it is a much faster card and requires more power than the slot it is in can give it. The nvidia card is smaller and has no fan, only a heatsink. It isn't drawing near the current that the ATI card will, and I haven't seen many, if any posts about dual displays not working on the ATI. Flickering, yes...... but not that it doesn't work. I agree with the other folks that have posted, it's a hardware issue with your video card, or the cables used to hook up the monitors, or possibly the displays are not standard in the way they use the DVI signal.... You can troubleshoot by trying your known good Apple CD on each DVI output, then place it on one DVI and try the BenQ on the other DVI. Make sure you power down in between your tests. This is to make sure you don't blow something, and the video card can reset itself to which display is hooked up. Do either of the BenQ displays work with DVI on either output?..... once you layout your results, you may see a pattern that will help you explain the problem to Apple. I think they may need to send you a replacement video card, but I'm not there to see what is happening. Playing out the scenarios you tested usually makes them pay attention, instead of calling and saying it doesn't work. They put all these issues into a database that they search when customers call with issues. Wow, have I been long-winded!
Good luck

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.

Acroread full screen problem - dual display on Linux machine

Hi:
I am running Linux Fedora core 15 on an HP laptop that I use for presentations. I have dual displays set up and run my presentation software (opera and acroreader) in the external monitor in full screen mode. This works fine for opera, but when I try to use acroreader, it only appears on the laptop's built in monitor when in full screen mode. Any suggestions on how to get it on the external display?
Thanks.

When you normally play iTunes on a secondary monitor (23" Cinema on the side) and then disconnect to go mobile, there's a problem - can't get video window to show up anywhere without changing preferences to have video display in iTunes window or art window. Disabling spaces, checking display, "detect displays", nothing else works.

Dual Display Problem with new MacBook Pro

Hi All,
I just got a new MacBook Pro Core 2 Duo and a 30" Dell LCD Monitor. Both are AWESOME products, BTW. But I am having a weird issue with running both displays.
If I sleep/wake the computer so that I'm never running with dual displays, everything seems fine. However, no matter what I try, I eventually get a system hang if both displays are active at once.
For example, if I turn the MBP off, attach the monitor, and power up, the MBP will get to the login screen. As soon as it hits the logon screen, it hangs.
If I hot-plug the monitor while the system is running, it will detect the new display and activate it as a secondary desktop. But, in anywhere from 5 seconds to 15 minutes (varies each time) the MBP display will turn off and the system hangs.
To me, it seems like a video driver bug or something similar to that?
Thanks!

To those of you that inquired, NO, I have not yet resolved this problem.
I took the laptop into the Apple store, and they decided that it needed a new logic board. Then, once they received the part, and I took the laptop in for repair, they didn't replace the logic board. The guy on the bench reset the PRAM and decided that the problem was resolved. I took it home, and within about 20 minutes the same thing happened.
When I took it back to the store, I was unable to reproduce the problem for the mac Genius.
It still does it, I I just haven't had a chance to take it back to the store to try to reproduce the problem again.

10.10.3 dual display problems

Like a few other on 10.10.3 with multiple displays i have started having issues with Dual display in that i have a third party application (Freeway Pro 7) which has been working fine, I use the second display to display a variety of other windows, since 10.10.3, OSX cannot seem to remember where these windows should be between sessions of using the App.
So i can use the third party app, then switch to Mail , then back to the third party app and the various windows are all on the main display and the second display has nothing on it at all.
What is going on Apple.

I did not mention this before, but i have another system based on the MacBook Pro and this issue does not appear on this unit.
This system is a registered system on the Public Beta program so i thought it may not be relevant.

Dual display color and other related issues...

I have posted this on painter forums, though some of the issues coming together here are directly related to issues w/ Snow Leopard and dual displays. Thought I would try here....
This is so bizarre. When I ever I run P11(I think this is going on in P10 too?) w/ the OS X (snow leopard, 10.6.2 on quad core Intel Xeon Mac Pro, 10 GB of RAM) menu bar on my Eizo(making it the main display), and the Apple Cinema display left as the #2 monitor, I get very annoying brush cursor artifcats left randomly on the Eizo screen after strokes. One cannot predict when the cursor will leave it's gray "marks", but it will do it, sometimes 5 strokes in a row, sometimes after 15 strokes or so? If I move my brush back over them, or change the image percantage view, they vanish, obviously new ones coming back, as I work.
However I put the OS menu bar on the AC display, yet work back on the Eizo, this does NOT happen. No cursor artifacts. Well, at least I can summon the issue
The reason I am doing this is Snow Leopard has bad color issues w/ dual displays (well documented, much to Photoshop CS4 users frustrations, and mine). Apple needs to fix it... but for me to see the right color on the Eizo(this is my main color and superior display), it needs to be the main monitor(menu bar) in 10.6.2.
So, you can see my trap - Accurate color, or annoying cursor artifacts left on the screen (sorry, it really bugs me as I work) as I work in Painter.
Attempted fixes: Trashed all of Painter's prefs, all of Wacom's Intuos 4(latest driver) prefs and software, switched plug ins on the back of the mac for the displays(lots of restarts), ran cache cleaning Cocktail and DiskWarrior, etc. -- no change, as I can duplicate the issue w/ the above set up. A sidebar or maybe be very related note: I have an iMac w/ max amount of ram (model not very old -- maybe 1 or 2 old) and I have had a long standing issue working on the iMacs we have had w/ this brush cursor artifact problem (in Leopard and Snow Leopard). I am on one monitor w/ the iMac, so you know here the menu bar is...hmmmmmmmm.....?
Thanks!, T

Wacom tablet on dual display dual card setup...

...and the cards are as follows, one Geforce GTX 460 (nvidia driver), one Radeon x1650 (radeon driver) As such, I have to use Xinerama and not RandR for my dual display setup. I have configured the driver to use my main display (Dell CRT on GTX 460) and the cursor shows up where it's supposed to, but when I draw, the cursor "splits" into two, the actual cursor, and the drawing cursor. The regular cursor moves as if it's on my main display, but the drawing cursor spans both desktops.
I've tried all kinds of things to make it work, no luck though.
xsetwacom set "Wacom Graphire4 6x8 stylus" Area 0 0 30408 12064
xsetwacom get "Wacom Graphire4 6x8 stylus" MapToOutput HEAD-0
Both of those commands produce the same result, which is shown in the video below.
xorg.conf
http://pastebin.com/d0TSwNrR
And a lovely video showing what I mean.

MisterAnderson wrote:Honestly no clue how to help you, but I am interested in your setup. Are you using the proprietary drivers for your nvidia card and the opensource radeon for your ati? How did you get this setup working? I've been trying for ages!
If I remember correctly, I just used --nodeps and maybe --force when installing the nvidia driver, that way it didn't force me to uninstall the radeon driver when I install the nvidia driver. Then, look at my xorg.conf. there's no acceleration of any sort on the ati card, but I can use it for terminals and browser windows, text editors and the like. Can't watch flash videos on it though, and I don't think mplayer works on it either, I'm not at my arch box atm, so I can't verify that.
Also, as mentioned in my opening post, no composting either. The same setup works pretty good in Ubuntu with a similar config, but no compositing there either, Unity clones 1680x1050 of my main 2048x1536 display, can't split the desktops, and I just end up using Xfce4 because it handles Xinerma pretty well.. I have to turn off the compositing extension in the config on arch to get X to even start up.
:edit:
back in arch, should note that whenever I install a new package, I receive this warning. Everything still works tghough as I describes. And back on topic, anyone have any clue as to why my tablet behaves this way?

Dual Display on Mac Mini

Hi there,
I want to have a dual display setup with my Mac Mini. There's also a twist. One of the displays is a regular monitor. The other display is a 46" TV. I am not too technically minded - is there a splitter or some kind of dual display "kit" I can pick up?
Thanks!

Which Mac mini? The new one has two video outputs on it, so two displays is not a problem.

Dual Displays and Windows XP

Hello,
I have a MBP with the Radeon X1600 graphics card. Under OS X I can run dual displays without a problem, either extended or mirrored. Using Bootcamp to boot to Win XP, I can only get the 2nd monitor to run extended, I can't get it to run mirrored. What really drives me nuts (short trip) is that I have run it in mirrored mode before when I teach. I go to the Display dialog box and "see" both monitors, but the only way I can get anything now on the 2nd is to run extended? I could update Radeon driver on the Windows side, but I thought BootCamp took care of that and I don't want to mess up my laptop?

It is definitely best to reinstall anytime you make a major system change. You will have to do at least a windows repair although I am not sure if it will fully enable the dual core.
Good Luck
Jeremy

Dual Display, 2 Monitors - Extended Desktop

Hello Everyone:
There isn't a clear cut answer or solution in connected a Macbook Air to 2 external monitors in an attempt to create an extended desktop. I have read older posts that it's either doable or not doable. My questions are the following:
-Is it possible to connect a new Macbook Air to 2 external monitors for extended desktop purposes?
-Some users have reported lag issues (mouse dragging , delays, etc.). Will this happen for sure with a Macbook Air or is it a monitor issue?
-What's the best non-Apple monitor brand that would work best with a Macbook Air for dual display purposes? I've read that Dells have a problem in this regard.
-What would be the advantage or disadvantage of using a dock station in setting up a dual display environment? Would this add to the lag, latency factor?
I'm thinking of investing in a new Macbook Air, but I want to make sure I dont end up with silly issues - such as latency, monitors, etc.
Thank you for all your help and advise.
Best,
G.

Yes, extended desktop works with monitors set to differant resoultions. the Monitors pref pane allows you to select relative arrangements and rez of all monitors composing the extended desktop.
personally I run a dell CRT at 2304 X 1728 @ 60Hz along with an NEC 6FG a 2048 X 1280 @ 60Hz off a radeon 9800pro on an MDD.

Mac mini dual display - blue screen flashes frequently

I recently purchased a mac mini i7 model, with fusion drive.
I have upgraded the RAM to 16GB.
I have also purchased 2 monitors, both are LG 22EA63V LED.
I connected one monitor direct HDMI to HDMI.
The other monitor is connected from Thunderbolt to HDMI.
Everything worked amazingly well for the first few weeks. Now, not so much....
I frequently have the screen freeze and flash blue, and then resume as normal dual display mode.
Other times the screen will flash blue and then come back as a single display. In this case the Thunderbolt to HDMI display appears as primary display, while the HDMI display loses connection.
If I unplug the HDMI display completely, the blue screen flashing does not happen at all.
So, what could be causing this problem, and how do i fix it?

Hi Matt,
See if there's some setting on the HDMI monitor for Input Source, or things like Auto-tune.

Colour management warning for dual display users

For those of you who require a colour managed workflow and have more than one display, be very careful in Mountain Lion. It appears to have a bizarre bug where images loaded and shown on the primary display (e.g. in Preview) are initially rendered with the colour profile from the secondary display, or something along those lines. Dragging the display window to the secondary display and back again sorts things out. I've filed a bug report.
If your two (or more) monitors have the same colour profile, you won't have a problem. The only workaround I can see is to set your least important display(s) to all have the same profile as your (probably calibrated, if these things matter to you) primary display, at least until (if?) the bug gets fixed.
If you want to see it for yourself, set your two displays to differing profiles - e.g. NTSC (1953) on the primary and Wide Gamut RGB on the secondary. Then load an image into Preview - something with lots of shades of red "works" well for the colour profiles mentioned. Take a screenshot of the Preview window as a reference. Move the window to the secondary display; note the colour shift as it gets re-rendered. Now drag it back to the primary display. It'll look quite different compared to the screenshot you took earlier, despite the fact it's the same image being shown by the same application on the same display in the same window... All you did was drag the window between two monitors and back again.
It doesn't seem to matter if the image in question has a colour profile embedded in it or not. When comparing with your screenshot, feel free to drag the screenshot between the monitors too - after all, it'll be suffering the same rendering bug! You'll still see a different result; in fact it may even be magnified by the accumulated rendering errors.
Preview isn't the only application affected; I've seen identical issues under harder to replicate circumstances in Safari, for example.
Given this fault and others I've seen with colour rendering in Lion, plus several new bugs found in Mountain Lion, I'm afraid that if a colour managed workflow is important to you - well - Snow Leopard or Windows...?! Ugh, what a mess

I've encountered many of the same woes with color management being a graphic designer, but here's my issue:
Have a 15" (Early 2011) Macbook Pro. It is turned on with me hooked up to my Dell U2410 and display open for a dual display configuration. The Dell is my primary monitor.
I then unplug my MBP to use it around the house. I go to plug it back into the Dell for my dual monitor. I notice that the color on the Dell looks good, but now the MBP has a very blue color temperature. Like moving from the preconfigured 'Color LCD' profile to 'sRGB' which definitely shifts to a blue color on the MBP.
I check the color profiles in System Settings and the Color profiles are correct. 'Dell U2410' for my Dell and 'Color LCD' for my MBP. But as I said, it's much bluer than standard. I try to change the color profiles around on the MBP and no matter which I select it's always the same color with no shifts I would expect to see.
Only solution I have found is to restart my computer. Upon restarting all is well again in the world.
It's pretty annoying having to restart my computer everytime I plug it back into my workstation with Dell and keyboard.
Related note: USB does not work when I plug things back and again have to restart to fix this.
