Dual monitors reset on AE start-up

I'm working with a dual monitor setup with the timeline on the second monitor. Each time the program opens, the the timeline window appears centered on the main window and it needs to be repositioned over to the 2nd monitor.
I've tried saving the layout, without any effect on the issue. Otherwise everything works as expected. It's just annoying having to constantly move the window each time the program starts.
Any advice on how to keep this from happening?
Thanks.

This has nothing to do with AE usually. Such stuff is handled by your graphics driver and operating system. If you let them treat multiple monitors separately and not as one huge desktop, this behavior is to be expected.

No signal to dual monitors on start up

HP ENVY Phoenix 810-170st CTO Desktop PC, windows 8.1
Two computer monitors, same models, one connected by dvi and one by hdmi. Upon start up they will randomly fail to display anything and will say "no signal, entering power saving mode". Sometimes unplugging one while the computer is still on will allow the other to start displaying and I can log in then plug the other in. Sometimes though I need to manually power off the computer, unplug one, power back up, log in and then plug the other in. Both displays work, both cables are fine, it just seems that occasionally when I power up with both displays plugged in neither will recognize it is getting a signal. Furthermore, once actually logged in I can reconnect the second display without a problem. Any ideas?

Hello naros89,
I have read your post on how you are intermittently experiencing display issues from your dual monitor setup, and I would be happy to guide you towards a resolution! To begin, I will need to ask you a few questions:
Has your computer completed all of its important Windows Updates?
Have you updated your HP drivers using the HP Support Assistant?
Is this an on-going, or recent issue?
What is the Product and Model Number of your two monitors?
In the meantime, I recommend following this document on Using Two or More Monitors with One Computer (Windows 8). This should help stablize your dual-display setup by alloting one of your monitors as a primary display, and the other as a secondary.
Please re-post with the results of your troubleshooting, as well as the requested information above. I look forward to your reply!

IMac Dual Monitor, Mini-DP to DVI, Screen Blinking

2.4 Ghz Core 2 Duo, 4 GB Ram. ATI Radeon HD 2600 Pro graphics.
Been using Snow Leopard here at work, running dual monitors via Mini-DP to DVI cable. Never a problem previously.
Upgraded to Mavericks. Enjoying it. Until the 2nd monitor (Acer v223w) started intermittently blinking. Discovered I can trigger the blinking via the mail program on the second window - hiding and/or showing the info/mail activity left-side panel will cause the screen to blink.
Kinda befuddled. Any help?

I am having the excact same problem. With nearly if not an identicle system.
24" Mid 2007 iMac
Processor 2.8 GHz Intel Core 2 Duo
Memory 4 GB 667 MHz DDR2 SDRAM
Graphics ATI Radeon HD 2600 Pro 256 MB
Software OS X 10.9.2 (13C64)
Serial Number W87***B2ZCT
Display 1: Built-in iMac Display (1920 x 1200)
Display 2: ACER 23" Wide Screen AL2223W Display (1680 x 1050)
Since I updated to the latest version of mavericks the other night I have had frequent flickering and blacking out of my screen. It happens mostly when I mouse on or mouse off my dock menu, and open programs on the second monitor. There is also little yellow and organge flickers throughout the screen from time to time almost like an interference patter, generally 1px high and 20px wide with varying degress of static.
I have tried the following with no success:
- Reset my PRAM / NVRAM
- Reset my SMC
- Deleted com.apple display related files
- Used screenResX to try and find a different Display 2 options
- Lowered resolution of Display 2
This is extremely frustrating because I am a web designer and programmer, and having my 2nd monitor not functioning basically renders my work station useless for me.

Dual Monitor Out of Frequency

I am reposting this from another area to see if get a response here.
I have a G5 Dual 1.8 machine with a GeForce FX 5200 DVI-VGA and ADC-VGA adapters. It drives to 17in Daewoo LCD monitors.
It all worked fine with dual monitors until I upgraded to 10.4.3. First alternatively one of my monitors went out of frequency after working through most of start up. Then the next causing the same work. Then after getting it to work by swapping around the monitors and reseting the frequency down to 75hz, both monitors went out of frequency.
I reinstalled tiger and upgraded all the way to 10.4.2 and am able to use both monitors. I did this in both archive and full mode. I also upgraded in steps several times so I am confident it is a problem that ocurs with 10.4.3 upgrade.
So it looks like their is a bug in 10.4.3 that does periodically puts the frequency out of range for the monitor.
I am posting this to be helpful to others who might experience this problem and to request any suggestions that I might have missed.

Now I just tried 10.4.5. Still the same problem. So again I went back to 10.4.2 and the problem goes away.
Given the lack of responses to my posting, I am puzzled - there must be someone else out there with a fx 5200 nvidia and vga monitors - why am I the only one with this challenge?

Bridge Dual Monitors CS3 Workspace Questions

I can't seem to figure out a few things regarding running dual monitors. Run windows XP, have the latest bridge/cs 3 updates. Sometimes everything works fine, other times it doesn't.
I like having my preview pane on monitor #1, directly in front of me. I also like opening the selected photo in RAW from monitor #1 and having the RAW window come up on monitor #1.
Most often the RAW window will open up on Monitor #2, which I do not want to happen. On Monitor #2, I have my content pane and my metadata & folders showing.
I've reversed 1:2 and 2:2 and can't get it to work right either. Could someone provide some guidance? Been searching options and can't figure it out.
Another topic that is not related to dual montiors. Sometimes my preview tab, will not show the selected photo in it. I usually reset Bridge on start up and it'll be there...but sometimes the photo disappears. The tab will still be there. Any help/ideas would be appreciated.
Thank you.

I discovered that with dual monitors if the window is maximized it has no preview image (default workspace), just a green pane. If you use the double headed arrow and pull back the dividing line between thumb/preview pane or preview/metadata pane it revels dozens of "copies" of underneath. The preview will only show up when the thumb window pane is moved quite a ways to the left. It is almost like the real workspace is on the bottom and the others are on top.
The solution I have found is to click RESTORE DOWN (middle window icon) and then everything works correctly, even if I enlarge the window to full monitor. If I maximize it reverts again. Am using Vista and 2 monitors. Can work with this now that I know what to do, but a little puzzling. For anyone not seeing a preview image, or metadata, might be worth while to see if maximize window mode is the problem.
Perhaps you could experiment with maximize - restore down and see if it helps with your problem.
Probably get a better response if you post questions in Bridge question forum rather than feature forum.

Gnome Crashes on Login after messing with dual monitor settings

Gnome displays the sad monitor and has the error message "..something has gone wrong..~" and will force me to log out. I've only started to experience this after messing with dual monitor settings in nvidia. The dual setup(twinview) worked but once I rebooted, I couldn't get it going for awhile.
Here's my xorg.conf

Extra Notes: I have another desktop session with awesome installed(uninstalled now) and could log into that no problem. Awesome was giving me troubles so I uninstalled it. I have 2 gnome desktop sessions, my regular gnome session(the one that crashes), and the other with no window manager(never crashed on startup).
I installed awesome around the same time as configuring the dual monitor setup.
Thanks.

Update.
The crashes are to be expected now. I'm circumventing the whole thing by logging into my other Gnome session without a window manager, logging out and then logging back into my regular Gnome with Metacity.
I've noticed the tty1 sessions(not sure what's it's called) is strange. Apparently my session runs on tty8 but when I try logging in, it'll crash me and tty7 gives me a blank screen with a blinking underscore. The other tty1s work regularly. Not sure if this has anything to do with it.
Is there a way to just reset the Gnome settings?

HT5918 Mac Pro (Late 2013) Dual monitors freeze on startup?

I've got 2 monitors, 1 HDMI and 1 MiniDisplayPort/DVI into Thunderbolt, and the computer can't start, it crashes during the boot process. The main screen freezes just as the login comes up, the MDP screen is scrambled, and the mouse cursor is a spinning pizza.
The only solution so far is to remove the MDP cable during startup, but that is a dealbreaker because dual monitors is the sole reason I bought this, and c'mon it's a really expensive computer -- even my old MacBook could handle 2 monitors!
Any insights or solutions appreciated.

Have you tried another cable and adapter?
Try another DVI monitor to help determine the cause
Are you using a Thunderbolt port not shared with the HDMI port?

How to set up dual monitors with a Mac Mini

The Mac Mini has only one video output port. I very nearly didn't buy a Mac Mini system because I need to work with two monitors. I use the second monitor to display information in Web pages, PDFs, and Word documents while I am working in the main window.
However, I discovered after quite a bit of Googling that it is possible to set up dual monitors using an inexpensive USB video adapter (about $70).
So I bought my Mini (1.83Ghz, 2GB RAM, 200GB 7200rpm Seagate Momentus), and I also bought a USB video adapter called the EVGA Plus.
I've installed this system and used it now for a week, and I am quite pleased with it. So I thought I'd pass this information along to anyone who's interested. Please note that, although this is my first post to this forum, this isn't spam -- I have no financial relationship with any of the companies mentioned here, other than as a customer.
LINKS
EVGA Plus:
http://www.evga.com/articles/409.asp
Their literature does not mention Mac OS X compatibility. However, the underlying technology is made by Display Link. You can download beta Mac OS X drivers from their site:
Go to Display Link to download the beta Mac OS support -- see
http://www.displaylink.com/macbetadrivers.html
The disk image includes a very well written PDF document that explains the driver's status and limitations.

NOTES
* The DisplayLink driver is beta. It doesn't support 2D or 3D accelerated graphics. You can't use it to display iPhoto slide shows, for example. However, I need to be able to display a Web page, document, or PDF in the second monitor while I am working in the first. I've found this solution to be quite acceptable for this purpose.
* Several other companies make USB video units that use the same DisplayLink support, so they should work, too. However, they are more expensive -- largely because they're set up to function as port expanders, I believe. The EVGA Plus was the only unit priced under $100 when I did my search.
* USB does not have very much bandwidth, so you might be surprised that to hear that it's possible to use USB to drive a monitor! You'll find that the display isn't as fast as DVI, but for my purposes, I've found it quite acceptable.
* The EVGA Plus comes with a terrible USB to mini USB cable that will cause all sorts of display problems. Replace it with the type of cable that is used to hook up digital cameras to a USB port.
* Once everything is installed, you can use the Displays in System Preferences (or just click the icon on the menu bar) to adjust the second monitor. You can choose display resolutions (depending on your monitor's ability, of course). Rotation works. You can also right-click the second monitor and choose a different background color or graphic.
Don't expect miracles. Don't go this route if you want to run videos or games in the second monitor. And if you get an EVGA Plus, replace that horrible cable!
I hope this information is helpful.
Bryan

There has been quite a lot of discussion here about driving twin displays with the mini, and more recently about the potential for USB video adapters to facilitate this, particularly in the light of several vendors claiming they have suitable MacOS devices and drivers 'almost ready'.
The DisplayLink solution seems to be the one most suggested as viable, though it's a pity they have not yet been able to move their drivers from beta - I suspect that puts a few people off. It's therefore good to hear of a real-world experience that should help others decide whether or not to go this route!

I get that ^^: looks like the VGA screen IS 1280x1024, but for some reason ratpoison thinks it's 1280x800 (all open windows have that size).
this does not happen in DWM, but should work ok with ratpoison too...so I'm guessing it's a wrong setup on my part.
Enabling Xinerama in xorg.conf doesn't even start X at all...it segfaults
What other steps should I take to makea working dual monitor environment? I would like to have 2 X screens btw (my laptop to be screen :1 and CRT screen :0 (the default))

Scratch that..it was working..but silly me forgot to use ":nextscreen" in Ratpoison..so the windows would open at 1280x800 since the damn thing though I'm still on the first monitor

DUAL MONITOR BUG: One Picture – One Monitor – Different Colors!

There have been several threads discussing that Photoshop CS4 and OS 10.6. show wrong colors in dual monitor setups.
The first one to prove this with a screen capture was jb510-LJ0JJQ in August 2009: http://forums.adobe.com/message/2207312#2207312
Eight months and three OS updates later the problem is still there and makes professional work with more than one monitor a nuisance.
Here's another actual example: A picture and its 100% identical copy showing different colors on one screen!
Here's how to repeat it – try this at home ;-)
1) In the finder make a copy of a rgb picture.
2) Open one of the two identical pics in photoshop.
3) Drag it to the other monitor.
When releasing the mouse button you may see the bug already: the colors will "switch".
4) To verify this go to system presets - monitors - and change the primary monitor (by dragging the menu bar to the other)
5) Now open the identical copy you made in step 1) and see the difference!
Here's a synopsis of suggested workarounds:
1) disable open GL (which seem to makes no difference on my setup)
2) click "desaturate monitor colors" but set desaturation to 0 (which prevents visual switching in step 3) (only if openGL is ON) but also leads to a wrong display in step 4+5
3) make the hardware calibrated monitor your default monitor and strictly avoid changes or dragging pics to the other monitor (which seems to be the only reliable method)
4) some guys even force both monitors to use the profile of their hardware-calibrated monitor (using color sync) to make sure they see what they should see on at least that one monitor. What a stone-age workaround for the the world's leading imaging program!
Considering that reliable colors in professional (=multi monitor) settings should be the most basic function of photoshop this mayor malfunction should be solved with CS5! Otherwise we might have to live with it for some more years...
Have Adobe and Apple realized this bug and on their agenda? Will it be gone with OS 10.6.3? Can anyone explain the reasons for this bad bug? Is there a "officially" recommended workaround?
Thanks, regards,
Eric

There have been several threads dealing with this malfunction. But most faded out in silence or acceptance of the workarounds.

But man, this is no minor bug! Consistent colors are the by far most important basic function of photoshop. If you cannot rely on the colors in photoshop you can as well use "Preview" and "Word" for print production ;-)
Carson, how did Apple react to your complaint? What do you mean with "they don't get it". Do they not see it? Or can't they get it right?
Shall we open a thread at apple forums to point out that it's not the problem of a single user?

Dual Monitor Startup Problem on MacPro - Solved

I have a model 53135LL/A = mid 2010 MacPro with 8 cores, DUAL monitor cards and monitors, 24GB memory, running Lion 10.7.3. It is important to note that I am also using the Apple bluetooth Magic Mouse and the smaller, bluetooth keyboard (no numeric keypad). This unit was supplied with Lion in December 2011 and has had a startup problem from the beginning as follows:
1 - when starting from a cold start the dual monitor positions are reversed from the correct position
2 - additionally the USB and firewire connected devices (e.g. Wacom tablet, 2 card readers) do not function properly.
The workaround for me has been to start the system, wait for the logon screen, then click restart. Upon restart everything comes up and functions correctly.
Specifics on my setup and starting problems:
1 - My main monitor (Monitor #2) is a large gamut monitor that is located to the right. This monitor is connected to card slot 1 as that is the faster card slot (pcx16). The second monitor (Monitor #1) is an ordinary unit and connected to card slot 2 (pcx4). The monitors are set up as an extended desktop.
2. The Wacom tablet (Intuous 3 wide) is connected to USB port on rear of machine. CF card reader by Delkin is connected to Firewire on rear of machine, and an SD card reader is connected to USB on the rear of the machine.
3. My dock is positioned on the left side of the left monitor. The menu bar is along the top of the left monitor, and all desktop icons are on the left monitor. The right monitor has no items on it.
On a typical cold start, as mentioned above, the apple logo appears on the right and then the logon screen appears on the right.
If I proceed to logon at that point, all the desktop items move to the right monitor and the computer thinks the positions are reversed. In other words, it behaves as though the right monitor (#2) is on the left of the desktop and left monitor (#1) is on the right.
Additionally, the Wacom tablet using either pen or mouse does not map over the full desktop range. If I use either card reader and then eject the card, no further card insertions will be recognized.
To fix this, I simply restart the machine thru the apple menu and everything comes up correctly.
I had discovered, that instead of completing the logon on a bad cold start, I could simply restart from the logon screen and all would work correctly.
On occasion, the logon screen would come up on the left monitor (as it should do) and in that case, if I log on all works correctly.
I have worked with Apple support on the phone, clearing setup ram etc. Have had the unit in to Apple store for hardware check, all OK. Next suggestion was reload OS and start over - no thanks.
SO - Here is the latest.
If I turn off my keyboard and mouse before starting the machine, then wait for the logon screen to appear - It starts correctly, with the logon screen on the left. I can then turn on my keyboard and mouse and all works as it should.
Bottom line - there appears to be a startup issue with Bluetooth devices from a cold start. Note that once the machine has been used for a bit, I can turn it off for short periods of time (e.g. 30 minutes) and it will start correctly even with the mouse and keyboard turned on.

That's how dwm behaves. I believe dwm's multihead support is rather lackluster out of the box. You might want to check out some of the patches they have, and ask around in the dwm hackers thread.
I currently have dwm simply draw status on all monitors, but I'm investigating separate status bars per monitor. We'll see where that takes me. Dwm is a tinker's WM!

Dual monitor setup - primary monitor blank upon startup

Hello -
This has been vexing me for some time now. I've seen hints of this issue from other people but never the exact same circumstances and never do I see a definitive answer.
I have a dual monitor arrangement on my 8 core Clovertown (first generation) Mac Pro. After shutting the machine down, when I start it back up, the primary monitor almost always flickers very quickly then goes black while the machine boots, and the secondary monitor kicks on. Note - this never happens on restarts or waking up from sleep mode; just after starting up after completely shutting the machine down.
Exact specs are:
The afore mentioned first-gen 8 core Mac Pro (spring 2007), combined with an ATI 4870 graphics card, with the 24 inch Cinema Display LED serving as primary monitor (the one that's useless upon starting up), and my older 23 inch LCD as secondary display. Also worth noting - I'm aware the ATI 4870 is not officially supported in this generation of Mac Pro, however there were so many reports on the web of it working that I did the swap-out myself, and ended up getting the 24 inch LED since I then had the Mini Displayport on the back of my machine.
The only way I manage to get my machine working after starting back up is to restart it several times - literally up to over a dozen attempts sometimes, before the primary display finally does start functioning and I can begin working as normal.
Because there were many reports of the ATI 4870 working fine with this Mac Pro and word of other flickering monitor problems, I thought I'd ask despite the graphics card not being officially supported. Any ideas on how to remedy this problem so I don't have to keep restarting over and over before both my screens eventually work?
Thank you in advance.

So I have the same issue. I run dual 23" Apple Cinema Displays. For a while now the main monitor has had trouble waking up. I have also been unable to put the Display to sleep from the power button on the display. The other monitor seems to go to sleep fine. So when I get it to sleep and it won't start up, I usually restart and everything is fine. Today I can't get that monitor to come up at all. In addition, I have swapped ports on the video card switching the order of the monitors, no change. I also checked in my System Preferences>Display, and the system is still recognizing two monitors. So I am guessing my issue is related to the Display itself. What can be done at this point?

Dual monitor setup problems... help.

Hi all,
(Arch 0.8 & NVIDIA drivers)
I'm having some troubles setting up a dual monitor set-up on my machine... every time I save the settings after configuring them in the NVIDIA control panel they don't seem to save when I start the OS! I've also messed with the config file, so how do I set it back. At the mo it picks up the CRT monitor only & not the LCD.
There are Two monitors hooked to it, one LCD (main DVI) & the other CRT (to the right of the LCD). I want the LCD one to be the primary one.
LCD spec:

Thanks for you help & expertise here.

Dual monitor setup flashes constantly

I am trying to set up a dual monitor setup with a Lenovo Thinkcentre Edge computer. I reset the BIOS to enable multimonitor support and IGD Active Video. One monitor is plugged into the VGA port. But when I plug the second monitor into the DVI-D port, both monitors flash constantly and the speakers make the sound of a device being disconnected. Unplugging the DVI-D monitor stops the problem on the VGA monitor. I checked the drivers and they are all up to date. Any ideas?

Bad cable?

Systemd as user, dual monitor, awesome, popups (long desc inside)?

Okay, this is quite difficult to describe, so please bear with me.
I run systemd as user and awesomewm on a laptop which is normally plugged in to an external monitor for a dual screen. 64-bit Arch, fully updated, running [testing]
I've got my own homebrew script which basically just runs the appropriate xrandr command to enable all the current connected monitors (since AFAIK we still can't make that happen automatically at plugin/out of the VGA cable).
Additionally (may or may not be related), I run unagi for compositing and animated wallpapers using xscreensaver and xwinwrap. unagi is started as a systemd user service (as is awesome itself), as are the animated wallpapers (basically a homebrew service file calling a bash script). Also, I'm using infinality-bundle from bohoomil. None of this (I think) is important.
Now, not sure when this started happening, because I rarely do this, but if I start my laptop up with the external monitor plugged in, it mirrors the display at a fairly low res (I'm assuming 1024x768) which I don't bother about, because I just hit the keybinding for the above-mentioned script and get my full res dual monitor setup.
However, once this happens, any app which pops up, which in my case is synapse (app launcher), gmrun (launcher, run via xbindkeys) and keypassx (when requesting passwords) will always pop up on the primary screen. If launched from the primary screen, it'll turn up right in the center as expected. If launched from the second screen (on the right), it'll turn up on the primary screen, but centered in position w.r.t the second screen (different resolution) and to the right-most edge of the primary screen.
If I start the laptop without an external monitor and add it later on (plug in and then run xrandr) everything works as expected, popups are centered properly.
If I start awesome using gdm (and external monitor plugged in) it doesn't show the mirrored displays and everything works as expected.
Because of the last two statements, I doubt the awesomewm configuration is the problem, but I can't imagine how to proceed debugging this. Any suggestions?
EDIT: And as usual, immediately after worrying at this for a day and then posting this thread, I found something that 'works'. Restarting awesome in this case fixes it, and it remains fixed thereafter (till the next restart).
This raises another question though, I remember awesome would automatically restart with xrandr screen changes before, why isn't it doing so now? Or is it doing so too early perhaps?

Done.
Well shit. I guess I didn't need to do all that other stuff. I only wish I'd known about this before wasting most of my day. Thank you very much, everything appears to be working flawlessly now.
