Display sleep with dual monitor setup

I'm running a 17" studio display and a 20" studio display as a two momitor setup on a dual G5 2.0. The menu bar is on the 17". Unless I have display sleep in energy saver set to never, the 17" will go to sleep at the interval set in the preference panel, even when the system is in use. So far the only way I've found to get the display back off sleep is to put the computer itself to sleep - keyboard shortcut or by using the power button on the 17" and then wake it up.
I think this only started with 10.4.6. I can't upgrade to 10.4.7 yet - I run Avid Xpress Pro on the system and 10.4.7 gives dongle trouble. I've thrown away preference files, set and reset the sleep parameters. As it happens, I've had to reinstall the system a couple of weeks back, but the 17" studio still goes to sleep when it shouldn't.
The problem doesn't occur if the menu bar is on the 20" cinema display, but that's not the way I want it.
Anyone with the same problem,, or better a suggested solution?

finally found the solution (apple i hope your reading
this as this is a mad bug!)
you need to have the dock on the bottom of the main
screen in order to view the image on that screen.
Wierd, I have my dock on the left side of my main screen... which is to the left of my secondary screen. Perhaps you cannot have the dock in-between screens?
kgelner, how have you noticed the performance of your
card when working with aperture? Im seriously
debating upgrading mine as its just slow and annoying
I find it usable but I'm also only working with TIFF files (my camera is not supported). I am also pretty strongly thinking about going with the X800xt card, which should be at least twice as fast. Some operations (like a lot of Spot & Patch repairs combined with Shadows/Highlights) do make things a bit laggy.
I also have the 256MB version of the 9800, which I think helps with some of the larger images and operations.

MSI N560GTX-Ti Hawk PerfCap with Dual Monitor setup

Hi guys,
as far as I'm concerned, there shouldn't be a PerfCap when running a setup with two monitors on extend desktop setting, am I right? However, my GTX560-Ti does PerfCap and sometimes even does this while gaming (which is incredibly annoying). The only way to get it to clock up again is to reboot my PC.
My question is, why is that and how can I get rid of this behavior? I already tried updating the VBIOS but it didn't help.
Thanks in advance
Monsterkater

I'm sorry, I thought "PerfCap" would be a known term.
As the title states, it's a MSI N560GTX-Ti Hawk. The Card is clocking down, GPU-Z reports "PerfCap Reason: Util" which is, according to Google Search, because it isn't challenged enough. However, when running a dual monitor setup it should (again according to Google Search) always run at the default speeds (950/1050/1900 Core/Memory/Shader). I have updated my signature to show my system details as listed in the Posting Guide.
The temperatures under load are okay, the highest I have seen was 76°C GPU, 74°C Memory and 69°C VRM (all of them measured with MSI Afterburner). I have tried several drivers including Beta drivers and always checked "perform a clean installation". I also tried updating the VBIOS. I didn't know what else to try because Google Search doesn't yield much results for this.

Using this xorg.conf file, only my NEC LCD analog monitor could display KDE while the Samsung digital can't.
Any suggestions?

Thanks for your help guys, I'm halfway there.
The second monitor shows the KDE desktop, but it isn't exactly what I expected. Right now, both monitors display at 1024x768 (each) or 2048x768 (total). The larger monitor stretches and distorts the display of 1024x768 to its natural resolution at 1440x900 and it isn't what I wanted. Other than that, the dual desktop setup behaves what I expected to.

IChat screensharing won't fully connect with dual-monitor setup

I've read through several threads but none seem to match the peculiar problem I am having.
My mum just got a new "13 MacBook Air and an external LG LED (E2240T) monitor. I ran software update on it so her system is current, as is mine (late 2009 MBP/24" ACD).
Screensharing works fine when her external monitor is not connected but when it is plugged in and we try to screenshare the audio connection is established but sharing won't fully load and stops with this:
We tried unplugging the monitor and then plugging it in once the screensharing connection was established and that ended up with the image on my end freezing.
Anybody else have a similar problem? Any suggestions?
For what it's worth with her old (2006) MBP and old LG LCD we had no problems.

Hi,
I have an old 17" Studio Display (The one with the ADC connector) and a 19" CRT Screen that I have On sometimes with my G4/1Ghz Dual Processor.
This is running Snow Leopard.
If I share Screens using iChat with my MacBook Pro, the MacBook Pro puts the Screens Side by side as one picture (You cannot view just one screen).
iChat has a Software "Camera" that deals with the "Desktop" or what ever is on it as the pic for the Screen Sharing feed.
I have tried several Resolution settings on the CRT and iChat seems to cope (They are in a fairly narrow band though).
It might be possible that iChat is having difficulty if the two screens are vastly different in Size or resolution settings.
You seem to be describing using a 13" screen and the 21'5" one which may explain it.
There may also be differences in the Ratio.

ITunes Full Screen with Dual Monitor Setup?

This seems like a poor design choice but I can't figure out any way to turn it off. Seems stupid if you can't...
If you have two monitors plugged in and try to watch a movie in itunes (or the visualizer) in fullscreen, it will go full screen on one monitor fine, but it also makes the other one go black and unusable.
Does anyone know a way to make iTunes go full screen in only one monitor without pointlessly rendering my second monitor useless? It would be nice to be able to browse the web or do work on one monitor while having the iTunes visualizer (or watch a TV show) on the other monitor. Quicktime pro does this without any issues.
Thanks.

For your wallpaper drag the window to cover it.
What I mean is that I don't see how you can do what you want, cause when you watch someting full screen you usually don't want to see your wallpaper on your second screen. And that if you want to work on your second screen you won't mind not having it full screen.
QT pro will allow what you want cause it assume that you are working on your movie.

I have 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute?

I just bought a 12 core with Quatro 4000 and 5770, I want to use dual monitor setup, monitors are NEC with Spectraview-II. How do I connect? 4000 only has 1 Display Port and 1 DVI. 5770 has 2 of each, if I use both 5770 Display Ports, does the 4000 contribute any work at all? I read where on a PC they would work together, but on a MAC they do not.
I read that Display Port has higher band width than DVI, NEC monitors for best performance they recommend using DIsplay Port.
When I was setting this up I looked at a Nvidia Quadro 4000, unfortunately it was for PC, it had 2 Display Ports, in the Mac version they reduce it to one. I did not think there could be a difference.
Mainly want to use it for CS6 and LR4.
How to proceed???
I do not want to use the Quadro 4000 for both, that would not optimize both monitors, one DP and 1 DVI. Using just the 5770 would work but I do not think the 4000 would be doing anything, and the 5770 has been replaced by the 5870.more bandwidth.
Any ideas, I am a Mac newbie, have not ever tried a Mac Pro, just bought off ebay and now I have these problems.
As a last resort I could sell both and get a 5870. That would work, I'm sure of that, it's just that I wanted the better graphics card.
Thanks,
Bill

The Hatter,
I am a novice at Mac so I read all I can. From what I understand the NEC monitors I bought require Display Port for their maximum performance. The GTX 680 only has DVI outputs. Difference from what I understand is larger bandwidth with the DP.
You said I have the 4000 for CUDA. I am not all that familiar with CUDA and when I do read about it I do not understand it.
A concern I have is, that if I connect the 2 high end NEC monitors via the 5770, using it's 2 Display Ports I would have nothing connected to the 4000. Is the 4000 doing anything with nothing connected? I read where in a PC system the 2 cards would interact but in a Mac system they do not.
Bottom line, as I see it, the 4000 will not be useful at all to me, since I want a dual monitor set-up.
So far the 5870 seems the best choice, higher band width than the 5770, and it has 2 Display Ports to optimize the NEC monitors.
I'm not sure how fine I am splitting hairs, nor do I know how important those hairs are. I am just trying to set up a really fast reliable system that will mainly be used for CS6 and LR4. Those NEC monitors are supposed to be top notch.

Dual monitor setup with seperate resolutions

hey guys!
i currentley run thye latest version of archlinux with the cinnamon desktop environment and an nvidia geforce 7300SE graphics card.
im running a dual monitor setup with one 27" 1920x1080 monitor and one 27" 1024X768 monitor
because they have the same physical size they line up perfectley but because the resolution is different programs/mouse cursor movement doesnt, is there any way (without changing the resolutions) to compensate this effect so that in the eyes of linux/cinnamon the monitors line up so that for example dragging a window goes seamlessley between the 2 monitors.
i HAVE found out the panning option in the nvidia x server settings, but that really isnt what i am looking for...

A magnifier following the window down to the pixel, zooming to the exact size of 540 pixels the 384 pixels window could create an illusion of just that. It would be highly impractical however, not mention all the hacking time. Even if you would manage to get two screen with different sized icons, so that they match visually, the windows and fonts resizing on the fly, wmctrl might help with windows alone, no their themes (buttons, borders thickness etc.), you would still be left with a visually differently sized mouse cursor. Technically such a feat should be possible, but who is going to code it? Nvidia?

Does LR handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?

Does LR 5 handle a dual monitor setup with different aspect ratios (16:9 and 16:10)?
I'm planing to buy a 27" 16:9 monitor and use it as primary together with a 22" 16:10. Does any have any idea?
Thanks

Moreover, the two monitors can have completely different characteristics. As always, you really need to calibrate/profile any monitor (with a hardware tool - Spyder, Colormunki etc). That's no more important with two monitors, but you see for sure if you don't, as two dissimilar monitors will then probably look different.

Is a dual monitor setup with 2graphic cards possible?

HI.
What i want to do is run Archlinux on my Desktop but i dont want to miss my second monitor.
I could use both monitor on my nvidia graphiccard but i want to use the energy saving features too (wich dont work with 2monitor on one card) therefore my windows setup is big monitor on nvidia and the smaller one on the intel onboard card.
They both get recognized by lspci but only the onboard cards isy being used (the onboard card is the first card on windows too).
So is it possible to get it to work? Id really want to use ARchlinux on my Desktop too but i dont want to use it with one screen or without energy saving?
Working compositing is a must, i want to use gnome3 wich is the only reason to swich to linux for the Desktop (arch is running on the laptop for ages^^) but i dont need to, Win7 is working flawlessly fine and i didnt have to pay for it (msdnaa).
Thanks in advance!

hy do you need to clock down your card?
Most gpu have a function that clocks down the card@idle and or desktop.
In my case thats down from 850mhz(560ti)to 200mhz while using windows and 50mhz if the gpu load is low.
Thats about 20watts less then with full clock.
The problem is, that the gpu wont clock down with 2monitors on it, it stays at 850mhz.
Theres some driver tweaks for amd cards wich "fix" thatfix this (i believe its intentionl, 2monitors equals more load but its no problem with new cards...
Thats one reason i use my onboard gpu for the second monitor, it works well with windows and also means that swiching off fullscreen (games) to the desktop works a lot better, the second monitor can play a movie while playing wich doesnt work with one gpu and fullscreen.
I really dont need that with Linux since i use it for work and multimedia only but the energy saving feature is nice if the pc is on 8hours and more wich is often the case.
Can you tell which one do you run? I'm going to buy one for dual-monitor setup, and I'm looking for something that will work for shure.
As said dual monitor on one gpu works, amd can do 3monitors while nvidia can do 2 at once, that means if u intend to use 3monitors some day with ur card u have to buy an amd card.
i took the nvidia because is can use it to render videos with cuda support (its not working with all tools yet but its getting better and if it works its a lot faster then my cpu rendering).
PS: Thats one hread about the power saviing with 2monitors:http://forums.nvidia.com/index.php?showtopic=197557
since my monitors dont share the same resolution it seems that theres no way to make it work .

Dual monitor setup MBA 2013

Hello Everyone,
This is my first post on the Apple Support Community.
Nice to meet al of you!
System information:
Macbook Air medio 2013
Model MacBookAir6,2
Intel Core i7 1,7GHZ
8GB
512GB SSD
I am wondering if it is possible to have a dual monitor setup using the thunderbolt feature daisy-chain.
The configuration i am looking for is:
MBA --> Belkin Thunderbolt™ Express Dock (for using gigabit ethernet) --> Dell U2414H --> Dell U2414H
Specs:
Belkin Thunderbolt™ Express Dock = http://www.belkin.com/us/p/P-F4U055/

Do i have a chance this could work?
I'm looking forward to hearing from you all.
Thanks!

Hello,
I had the same problem with a nVidia GT120 card (2009 Mac Pro standard). OSX wouldn't show the gray screen on the 3090, even when it was connected alone (to the DVI port). Also, the login screen would always revert to the secondary display (connected thru the mini display port to DVI adapter).
After login, all was well.
Now I've solved the problem with an nVidia GTX 285 card. The 3090 is connected to the n.1 DVI port and the secondary display (a 1600x1200 Eizo L997) to the n.2 DVI port, and the Mac Pro boots correctly on the 3090 (gray screen and everything, at full 2560x1600 resolution).
Note that the first time I booted up the Mac after replacing the GT120 with the GTX 285 I had the same problem, and solved it by disconnecting the secondary display and then rebooting with the 3090 alone. Now everything works as it should.
Dont't know if there is a bug somewhere (EFI, maybe) of if the GT120 and your ATI are simply unable to work at full resolution before OSX desktop loading.

Dual monitor setup without using the ADC?

Would it be possible to run a dual monitor setup using a DVI splitter cable from my (2009)Mac Pro?
I've seen some old forums referring to the 2006 models saying that this wouldn't work and instead you'd get the same image on both screens but the newer Mac Pros state they have "Dual-Link DVI ports".
Just wondering whether this means what I think it means and you can connect two monitors via a dual link cable and get essentially, two monitors running independently as opposed to the same thing on both??
Hope it's staightforward and me just being slow.

The GT120 features one Dual Link DVI-I port and one Mini DisplayPort .
The DVI-I is Dual Link capable, and also can be directly adapted to VGA.
Single-Link DVI is a serial interface that carries three data bits in each signaling interval, as well as control signals. In general, Single-Link supports displays up to 1920 wide. Dual Link DVI is the same except that it carries six data bits in each signaling interval, supporting displays over 1920 wide.
DVI screen drawing is very similar to VGA screen drawing, and the data sent are digital "scan lines" left-to-right row data, top-to-bottom with entire screen data sent about every 60 Hertz. Analog VGA signals are sent at the same time on a separate set of pins.
DisplayPort and its Mini variant are inherently a packet interface, but can be coerced to produce a "Dual Mode" signal that approximates Single-Link DVI. Getting Dual-Link DVI or VGA from DisplayPort interface requires a non-trivial converter than contains chips and requires power.
Executive Summary:
If you have one display that is wider than 1920 or VGA, attach to the DVI-I connector with an appropriate cable.
Running a Mini DisplayPort display from the Mini DisplayPort requires only a cable.
Single-Link DVI can be had from the Mini DisplayPort with a cheap adapter.
Dual-Link DVI or VGA requires an expensive Active Powered converter which can cost US$100.

Dual Monitor setup for Mac Mini???

I just bought a VGA Y-cable and split my monitor signal to two monitors. Unfortunatley the same thing is displayed on both screens where as I was looking for an extension to my desktop.
I found this http://www.national-tech.com/catalog/dvisplitter.htm (the top one for $ 146)
I was wondering if I split the signal with a dvi splitter rather than a vga splitter if i could have a dual monitor setup with more screen space...
Thanks,

Monitor Profile incorrect on Dual Monitor Setup

Hello,
I've searched the forums and I can't find an answer to my problem. I've read about dual monitor setups in Windows and how to set the defaults and whatnot, but it doesn't seem to fix my problem.
I am running on an nVidia GeForce 8600M GT, Windows 7 x64, Photoshop CS4 x64. I calibrated my main display (Dell Vostro 1700) as well as the attached monitor (ASUS VK246H) using Datacolor Spyder3Elite. Both monitor profiles seem to load just fine. I've also went into Windows' color manager and set the system defaults for each monitor respectively. The problem I'm having is that if I were to load Photoshop on the 2nd monitor, Photoshop only uses the main display's color profile (Vostro 1700) and not the ASUS VK246H profile. What could be going wrong?
Just to clarify, what I mean by "loading PS on the 2nd monitor" is that when I execute Photoshop.exe, the splash screen and main window shows up on the 2nd monitor, not the main monitor (which is what I want).

function(){return A.apply(null,[this].concat($A(arguments)))}
Chris Cox wrote:
What if the image is in between two monitors?
The piece on each display is corrected for the display it is on.
Is it supposed to work that way? Because it doesn't. Not with Photoshop CS5 x64 at least.
As a test I intentionally misconfigured the profile for my Monitor #1 (left) so that it's REALLY OBVIOUS which profile is being used. When set this way, on Monitor #1 red colors will appear pale orange.
An open document, floating in a window:
If COMPLETELY displayed on Monitor #1, Photoshop will use the Monitor #1 profile.
If even 1 pixel of the edge of the image is moved onto Monitor #2, it will use the Monitor #2 profile on the entire image.

Dual-monitor setup + screen rotation

Hello, I want to use my desktop computer with a dual-monitor setup. I have connected both monitors successfully, but problems arise after this point.
The first problem is that they both just display the same screen and that xrandr only detects one screen called "Screen 0". I can change the screen resolution with it, so at least it sees things correctly, but I don't know how to extend my screen area to a new desktop. Not sure if this is relevant, but they're both monitors of the same model.
output of xrandr wrote:[user@archbang ~]$ xrandr
xrandr: Failed to get size of gamma for output default

The second problem is that I can't rotate my screen (I want this because it has pivot functionality). I'm using the xf86-video-ati driver.

Question about dual-monitor setup - advanced dock + PCIe card

I just got a Z60t at work. I had been using a dual monitor setup, but it doesn't look like my current config is going to fly w/ the new machine. Anyway, here's what I've got:
Primary monitor: Acer AL2416W (1920x1200 DVI)
Secondary monitor: Dell 1901FP (1280x1024 VGA)
I've read that the advanced dock might be able to let me use this setup with the Z60t if i put a PCIe video card in it. So here are my questions:
1. Will the advanced dock + PCIe video card allow me to run the two monitors listed above (I don't use the laptop screen at all)?
2. Which PCIe cards are compatible with the advanced dock?
3. Can I achieve the same resolutions with the advanced dock + PCIe card?
4. Will I need to split the VGA output, or can i use VGA + DVI like I do now (since the Z60t has no native DVI support)?
thanks!

Gary -- don't turn on the OS Display Mirroring. Turn it off.
You want Aperture to control how it uses your dual monitors. (You do not want the OS to determine it.)
Once you've turned off the OS "Display Mirroring", the set-up I specified above should give you what you want.
That set-up is:
"View → Main Viewer → {anything}", and
"View → Secondary Viewer → Alternate"
You must have the Viewer active (not the Browser) in order to change the "Secondary Viewer" setting. If you are in the Browser, activate the Viewer by double-clicking an Image.
Let me know if that doesn't work.
