Looks to be interference when dual screen

just bought this 21.5" intel mac, got the Mini DisplayPort to DVI Adapter to dual screen and the second screen sits there flickering like theres some sort of interference from somewhere..

I work on dual screens on a new mac pro but when I do the 4 finger swipe it moves both screens, is there a way to move just the screen that is active?

Multiple desktops and dual screens really aren't meant to work together. Apple came up with this multiple desltops feature and never really thought about users that use a dual monitor setup. So use either multiple desktops OR dual monitors but not both. Also don't try to use any App in Full Screen Mode as that doesn't work with dual screen setups either.

Remembering windows positions when switching from/to dual screen display

Hello,
Most of the time, a second LCD screen is plugged in my Macbook and configured as the main display. When I arrange the windows, I keep iTunes or my mail application maximized on the macbook screen and use the bigger external screen for all other windows.
If I unplug the external display, all the windows are of course moved to the laptop display. When I plug again the external screen, all the windows are moved to the external display. But I would like the iTunes and mail application to remain on the laptop screen.
Is there any utility to remember the windows positions and arrange them automatically when I switch from/to single/dual-screen display?
Regards,
Raph

Would DisplayWatcher do what you want? I came across this a couple of weeks ago but haven't had the chance to try it out yet.

Microsoft Word consistently becomes active window when clicking between dual screens and programs

13" MBP
2.3 ghz i5
8GB Ram
Running 10.9.2
Microsoft Word 2011
Dual screens with amazon Mini Display to VGA adapter
When I am running word between an external monitor and my MBP, Microsoft word always interrupts any clicks between programs and between screens to become the active window. This is especially annoying when I am trying to navigate between MacMail and Chrome, or any other programs.
The problem doesn't exist when I click between programs on the MBP, but only when I select windows between the two screens. Or programs on the external monitor.
Word is up to date, as is my MBP.
Please don't punt me to Microsoft, they're the worst!
Thanks!

There is a workaround for this problem, which was posted by Highestwater on the Microsoft Community thread for this bug and worked for me as well:
Go to
System Preferences > Mission Control >
and UN-check the box labeled "Displays have separate Spaces" (see image below)
The original poster on this thread may already be aware of this workaround, because he/she mentioned that the "separate Spaces" option is checked. But if you can live without the extra Mavericks dual display features (like going full screen in 1 display only, switching spaces independently on each display, and having a menu bar on each display), then uncheck this option and the "stealing focus" bug seems to disappear. For me the bug is so annoying that it's worth it to lose the extra features. Just yesterday I closed a Word document I was working on by mistake because I clicked on a Finder window on my other display and immediately pressed command-w to close it, without realizing that the focus had switched to my word document which closed instead. It was saved, but this sort of stuff interrupted my work enough to be both an annoyance and a time drain.

New window opens in main monitor when using dual screen

I am using dual screens and my "main screen" is on the left. Ever since Firefox updated to 32.0.1 on Monday I've been having this issue. Before the update, I would have my main Firefox window opened on the left and, when I click on a link to open a new window, it would open on the right screen. Now, it will only open on the left screen, where the other window is. If I drag the original window to the right monitor and open a link, the new window will open on the right monitor. But once I drag the original window back to the left, new links will open in the left again.
Before if I had this problem, I would simply drag the new window to the right monitor, then back to the left and close it. Then click the link again and it would open in the right. Kind of a work around I guess. But since the update, even this will not work. Any suggestions? Or is this a new function of the updated version? Is there a way for me to go back to the previous version? Any help is appreciated!

Hi hollytotheg,
I understand that links opening in new windows are opening in the active screen, not on the right, second monitor.
This may be helpful: [https://addons.mozilla.org/en-US/firefox/addon/monitor-master/] the search recommends this.
However I would also recommend suggesting an enhancement in input about dual monitor new window restriction.

Using Keynote with Podcast Capture and Dual Screens

Hi everyone,
We are trying to use a dual screen setup to record some Keynote presentations using Podcast Capture (i.e Dual mode, with the Keynote presentation in one screen and the presenter in the other).
The problem we are having is that when in full screen mode, Keynote takes control of both displays, thus stopping the Podcast application from being displayed. Even if we switch off the Presenter Display on the second screen, the second screen turns black.
I know we can start and stop recording with hotkeys, but we would prefer to be able to see the Capture app in one window with the presentation full screen in the other.
Perhaps this is just an oversight on Apple's part, but I'm finding it hard to believe its not possible. If anyone else has a workaround then please share.
Thanks.

Other applications are not visible when Keynote is playing back. Keynote takes over control of the graphics system when playing back presentations to enable Keynote to display properly.
When I play back Keynote and I want to look at a second application, I use a second Mac.

MSI gtx 570 twin frozr III - Dual Screen Windowed mode issues

Ok, so... I was running a solo monitor 1440x900 resolution, i recently purchased a brand new asus 24 inch 1900x1080 monitor. Basically what is happening is when i play WoW or Battlefield 3 in windowed mode on the 1080p monitor the colors are not perfect. When i go full-screen on the new monitor no issues, but that is not what i want to have to live with. When i say the colors are not perfect what i mean is, for example when i look @ the sky instead of being a smooth transition or blend from one shade of the sky to the next it is bars or stripes of each shade as if i am looking at the sky in 8 bit color instead of 32 bit color. Another thing to note is that when i login to windows 7 the blue screen where i input the password has the same effect. The 1440x900 monitor is running everything just fine. the only issue is with the 1080p monitor.
I am using DVI cabling for both, and have swapped them around to see if that was the issue, and sadly it is not. I am running the updated gpu driver, which i uninstalled and re-downloaded and installed again tonight.
When i use the HDMI cable, that fixes the issue but i need the HDMI for my 42 inch tv.
Also in windows, just to cover my bases with this post, i have the native resolutions properly configured, as well as in the game for the given monitor it is being played on.
Anyone know of a fix for this?
i7 2600k
asus PBZ68-v Pro/Gen3
Msi gtx 570
Samsung syncmaster 953bw (1440x900)
Asus VS248 (1900x1080)
I am more than happy to re-explain anything that may not be as descriptive or clear to you just let me know!
EDIT!
When i run the 24 inch 1080p new monitor as my only monitor on the system, everything runs perfectly...
Edit #2
Ok so i have pin pointed a possible cause
This msi gtx 570 struggles with operating multiple displays with different resolutions, while dual screening with my 1080p television and the 1080p display, everything runs as expected. Having to also render a 1440x900 display is probably the reason i am having the graphic issues. Is there any type of utility, setting, or other fix to this type issue? also this gpu is certainly less than 2 weeks since i purchased i could get a different card to remedy this... any suggestion? if you suggest a different card can you say so with certainty that it will work properly under the condition in which 2 resolutions will be required?

Ok, the problem is fixed and Svet i skipped a step or two. I installed the new driver with the clean install to save time for an initial attempt. What is interesting is that with the Geforce driver, only one 1920x1080 resolution was available
The msi driver gave me 2 options, 1920x1080 and 1920x1080 (native). The latter resolution fixed the issue for whatever reason.
The solution to this problem is so easy, when i purchased battlefield 3 it prompted me to download the geforce.com driver and i did not think anything of it at the time, lesson learned.

Maximising 2 programs using dual screen on mac mini.

I am using a mac mini with 2 screens and am trying to use it like my pc. I want to maximise a program on one screen and keep the second screen free to do the same. This works well on pc but not with my mini?
When I mazimise one program it creates a grey image on my second screen, making it useless for anything else.
Is it possible to maximise 2 programs (one on each screen) as is easily done on a pc?
How does this work?
Thank you.

It depends on the App's and setup that you are using..?
Have a look at > Using Dual Displays on Mac OS X: The Experience
or something at > Dual Monitor Setup with Apple Mac Mini-YouTube
It's hard to fully explain, but from what I'm seeing not all App's allow full screen mode without interfering with the dual screen setup and you might have to run most App's in maximum window size instead.

Clipped screen on dual screen+compiz+nvidia

Hello everybody,
I am connecting an external display to my laptop. The laptop display is 1280x800, while the external display is 1280x1024.
NVIDIA is configured to run two separate Xscreens, opposed to the TwinView alternative.
Compiz works on either screens without slowdowns, but the lower area of the external display is black.
It seems that Compiz is running on each screen at 1280x800, and since the external display is larger, a black band is shown at the bottom. How do I configure Compiz to use the full resolution on the external display?
Metacity isn't affected by this issue.
Did you ever experience that? There's not much on Google about that (or too much, searching for compiz+nvidia+dual screen gives too much results )
Forgot to say: this applies to Compiz 0.7.8 and Compiz 0.8.0 upgraded today. Affects Ubuntu and Arch either using NVIDIA 177.x or 180.x.
Cheers,
eaZy

I still haven't found a solution, but I managed to work with Compiz on the main screen (in my case the laptop) and Metacity on the other screen...
I'm starting compiz with
DISPLAY=:0.0 compiz --replace --only-current-screen
and metacity with
DISPLAY=:0.1 metacity --replace
This is working, apart of small focus bugs: changing from an active window on a screen to an active window to another screen is impossible, the only solution is clicking on a unfocused object and returning the focus to the target window.
That's actually the work around I was looking for! Thanks a lot. I'm using a 26" tv as the secondary display and compiz is kind of pointless on that, at least to me. For some odd reason I've also noticed that when I set the larger display to a resolution lower than the main display (the laptop lcd), there is no bar with compiz. I don't know how solid this is because after a few restarts it went back to the intended resolution, but since doing the same step again it's been working for now.
To illustrate what I mean:
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "AddARGBGLXVisuals" "True"
Option "TwinView" "0"
Option "metamodes" "DFP-0: 1280x800_60 +0+0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
Section "Screen"
# Removed Option "metamodes" "DFP-0: 1280x800_60 +0+0"
Identifier "Screen1"

Monitor "Monitor1"
DefaultDepth 24

Dual screen - at a loss

Hello all. Is there anything special at all to dual-screening mega 180?
I Installed everything, the CD. Then I powered it off, plugged my second screen in the secondary VGA plug.
While XP was booting, both screens showed - perfectly - the booting screens.
Then when windows was fully loaded, the secondary screen fried. It is NOT a screen failure, as when I plug the primary screen in the secondary VGA plug, it won't work either, though it won't fry. I can test that because the secondary screen will still show windows, though badly distorted so I just have to exchange their positions to test.
So is that a Mega 180 RMA? Or is it something I forgot to do? Does anyone know how to get my screen back? Symptoms are as follow:
the image is WAY too large (inches more than the screen left, and right, with H-size set to minimum). It seems the problem stems from the H frequency:
the correct screen shows H-50Hz V-60Hz the incorrect one shows H-40Hz V-60Hz
Any programs can set those values?
Anyways thanks and good day to you all!

As an update, I tried switching the main display to the MBP. Nothing changed.
However, I changed the rotation to 90 degrees and everything is back to Normal! Aside from the fact that I'm looking a 24" screen in the vertical position.

WINE and my Dual-screens

I have looked around, quite a bit, haven't found a answer that i've been really looking for...
I'm a big gamer, and I run two 17" flatpanel monitors at 1280x1024 on a NVIDIA GeForce GTS250.
When I run apps in WINE, it tries pushing each app out in 2560x1024, such as World of Warcraft... now, for WoW, it doesn't bother me. because my UI scales to 1280x1024 for some reason anyway.
As for games, like PoRTaL and Left4Dead.... it's trying to squeeze 2560x1024 into one monitor, making them pretty much unable to play..
I have tried emulating the app in a virtual environment, at 1280x1024... and I really don't wanna disable my other monitor every time.... Because I use them for Cheats, or a guide, whatever I tend to use it for...
Is there a way to push these apps into 1280x1024 instead of my dual-screen resolution?
It's one of the main issues for me keeping Winblows 7 on my computer... pretty sure once I figure this out, i can get rid of it.
Sorry if this has been answered elsewhere, probably wasn't searching the right terms and what not.

Perhaps, if you are interested, you could setup a new xorg.conf which has separate X sessions for each window (rather than TwinView), such that you could open up what you want on one window, then play your game on the other. Even if that is beyond what you want, you could check out ways to dynamically turn off screens:
https://bbs.archlinux.org/viewtopic.php?id=81310
For a while there I would launch games via scripts, which called xrandr first to turn off my second screen, but these days I launch everything with xinit to avoid turning off/on compiz for max performance.
I'm interested to see what you decide on, post back here
I have thought about both options, and I'm not sure if I wanna do either of them,
I mean, I want WINE apps to go into 1280x1024 which makes sense that I won't be able to unless I disable a monitor or run two separate X sessions, which I'll probably set it up to run two separate X sessions.
Still doing some research and making my decision.

Dual screen HP Pavillon P6-2427eb

Hi,
I have recenty bought a HP Pavillon P6-2427eb PC.
It has a seperate video card with a DVI + HDMI connection.
I want to use dual screen, but when I connect both screens it doesn't work.
The first screen is a fujutsi siemens screen wich is connected on the DVI connecter.
The second one is a HP 23" screen with Displayport connection (also has DVI + VGA) but I get no signal on it.
When I connect the DVI to the HP screen, this one works, but I can't get them both to work.
On the motherboard there are 2 DVI connectors, so I removed the seperate video card and connected both screens on DVI, they both work but duplicate the image.
When I look in the settings of my screens, and try to activated dual screen it says only one monitor is connected.
Any suggestions?

Hi JumJonckers, You have an ATI graphic card right? have you installed the latest ATI driver for your graphic card?
Please have a look on your graphic card multimonitor FAQ:

Mountain Lion Dual screen window Full screen problem?

I could not upgrade from Snow Leopard to Lion on my iMac because dual screen operation was broken when a window on one screen was set to full screen. Has this been fixed in Mountain Lion?

Hey Cuckoo
i Use an iMac with 2 dual screens and the problem you are describing is fixed in the final build release of ML.
i have not seen the breaking of activity when switching too full screen on even all 3 monitors. so looking good in the multiscreen support.
cheers

'Interference' when switching users

I recently encountered this problem where, when switching users, the screen looks like TV interference for a split second instead of the cube effect. It doesn't always happen, just sporadically. After looking on the forum and contacting the helpline chat with the support team, the iMac was taken in and a new logic board fitted.
Upon returning home I discovered that it stills happens, still sporadically but it happens. This would seem to eliminate the fact that it could have been the start of the leaking capacitors as this is a brand new board ( I did check that it was different from the last one ).
I have also read on here that it could be a software issue in Tiger, as with others I don't recall it happening with Panther, but my mind might be playing tricks ?!?!
Has anyone come across this, gone through the same solution process, and still have the issue ? Have you come across a solution ?
Many thanks.

Just to be clear, I installed the 2GB of RAM the day that I bought my iMac and neveer saw the problem until just before my midplane failed. Given all the info about the industry-wide capacitor problem, I seriously doubt that the RAM is related to any of this, including the interference.
The midplane issue involves failing capacitors which could affect many parts of the midplane, including the video. The failing caps might be related to the video issue. All I know for sure is that I saw the scattered picture, then my midpplane went. After it was replaced, I didn't see it for a while, but it did eventually return with no other symptoms, so my assumption is that it is unrelated.

KVM Between Mac Mini and Dual Screen PC????

Hello All,
I was wondering if one of you has the answer this.....
For work I am now working remotely from home. I have a ThinkPad W520 with Dock and two 19" ViewSonic monitors both with DVI cables. Since space in my place is an issue, I want to share my sons desk wich has a Mac Mini with an HDMI to DVI cable to a 19" Monitor.
My question is......is there a KVM switch out there that will allow for my setup plus keyboard and mouse to be used with the Mini? Then he can run dual screens on the Mini when I am not working.
Thanks for the help with this one!
Alex

I am not aware of any KVM which can share two screens. The best you are likely to be able to do is put one of the screens with the keyboard and mouse on a KVM and share those.
