Dual monitor setup broken in Leopard

There are numerous problems running an external Cinema Display from a MacBook Pro using Leopard. I've tried with 2 MacBook Pros (one 15", one 17") and 2 different Cinema Displays (24" and 30"). Not to mention everything was fine under Tiger. Both Leopard installations were "clean installs".
1. Closing the lid of the MBP doesn’t remove the screen from Leopard (Or Spaces).
2. When the MBP sleeps with a Display attached it never comes back onto the Display, only the MBP’s LCD.
3. Periodically the MBP refuses to wake when it’s connected to the display.
4. I can no longer use the power button on the Display to sleep/shutdown the MBP.
5. Simply plugging the Display sometimes causes it to wake (while the MBP is closed). In Tiger, I had to have the Power Adapter connected to wake my Sleeping MBP with the lid closed (as stated in the documentation).
Wonder if all this will be fixed in 10.5.1 (hoping)?

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 Using just the 5770 would work but I do not think the 4000 would be doing anything, and the 5770 has been replaced by the 5870.more bandwidth.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 - need laptop on the left

Hi All
I'm running a dual monitor setup - specifically a HP G72 laptop and a widescreen monitor. I use the monitor as the default and sometimes I want to use the Laptop as a secondary screen for watching TV etc. My desktop is Enlightenment, I just changed to it from Gnome. My issue is that I want the laptop to be on the left of the monitor - that's how it is physically positioned - but when I switch the Laptop screen on all my applications shift over to the laptop screen. I've written 2 scripts, attached to hotkeys, one to turn the laptop off and the other to turn the laptop on. The script to turn the laptop on is as follows:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --left-of LVDS1
This works fine, applications stay where they should be, except that the physical position is incorrect; VGA1 should be to the right of LVDS1 like this:
xrandr --output LVDS1 --mode 1600x900 --pos 1600x0 --rotate normal
--output VGA1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --right-of LVDS1
However, when I use the second script all of the applications shift to the laptop but at least the physical position is correct. The issue appears to be something to do with laptops, almost as though when it's a laptop the default monitor is forced to be on the left. Has anybody got any suggestions how to get around this issue?
Thanks
Richard

This is due to your window manager treating the two monitors as a larger 'desktop' area - that combined with your specification of the pos=0x0 you are telling it to do this.
If you have only the VGA output on, the top left corner of the VGA monitor is 0x0. If you open a window, and it is placed 10 pixels in and down from the top left, it is at coordinates 10x10 in the x session. Then you turn on the laptop monitor and specify that the top left corner of the laptop monitor should now bo considered 0x0 - but nothing is done to move the windows, so the window with coordinates 10x10 is now near the top left of the laptop monitor.
I see 3 possible ways of acheiving what you want:
1) swap the "pos" parameters in your xrandr commands so that the monitor on the left is always at 0x0 and the one on the right is always at 1920x0 (or whatever). This will leave a large area of available X desktop that is not visible - I don't know how your window manager will treat this. It might try to map windows on the laptop screen space even though that screen is not on. I know openbox is easy to configure where it tries to place windows.
2) Keep the VGA monitor always at 0x0, but place the laptop monitor at a negative offset when you want it on. I don't actually know if X allows negative coordinates like that, but it's worth a shot.
3) Configure your window manager, or use a different window manager, so that it is aware of the two screens and treats them reasonably (e.g. moves windows when the desktop area is changed).

Maximising Safari on a dual-monitor setup (GUI behaviour in Window XP Pro)

When I maximise Safari on the 2nd monitor of my two-monitor setup, it disappears off-screen (but its icon still remains in the XP taskbar) and I am unable to bring it back into the viewable area. Consequently, I have to close Safari and reopen it to continue.
When I maximise Safari on the 1st monitor it fills the screen as I'd expect.
Windows XP Pro

Confirmed on another Dell D610/Windows XP dual-monitor setup.
However, when I maximise safari on the secondary monitor it still appears on the task bar, enabling me to right-click and Restore the window (whereupon it reappears).

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/
Dell U2414H = http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&sku=860-BB CG
Do i have a chance this could work?
I'm looking forward to hearing from you all.
Thanks!
Kind regards,

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 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?

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?

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.

In dual monitor setup firefox 9.01 menus blink in and out

Every version of firefox AFTER the 3.6 series has problems in dual monitor setups and I want to be able to keep all tabs I had open when I close firefox so when I open again they are there. In dual monitor if I use monitor 2 for firefox (which is the way I use it) the menu blink rapidly when I click on them and make very hard to navigate. What is it with the video setup in win7 I have to use an older version of winamp due to tearing in the second monitor? Have all you companies not fully learned who to implement dual monitor setups properly or is that not really a concern?

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
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200

800x600 0.0

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.

I have a dual monitor setup. When I paste develop settings from one image to another, Lightroom switches the active window.

Strange problem. Lightroom 5.5. Windows 8.1. Dual monitor setup.
I'm processing a large batch of photos. I have Monitor #1 set as my main develop window, with Monitor #2 set only to display a larger version of the image I'm working with. If I copy the develop settings off of one image and try to paste them onto another image, Lightroom will switch from Monitor #1 to Monitor #2 as the main develop window, and will not display anything on Monitor #1.
If I then try to paste develop settings onto another image on Monitor #2, LR will then display a larger version of the image I'm working with on Monitor #1.
To work the way I want to, I have to continually drag my develop window back to Monitor #1 every time I try to paste develop settings onto a new image. How can I make this stop?

I just tried what I think you’re saying you’re doing and I don’t have the problem with LR 5.5 on Windows 7 SP 2.
Does the same thing happen whether you use the key shortcuts vs the Settings / Copy/Paste options on the menu?
I ask this because if you’re using the keyboard shortcuts, maybe you have some display-manager program that has bound itself to the Ctrl-Shift-V (paste settings) to the function of move-to-other-monitor which would do at least part of what you describe.
You can also test this theory by doing a Ctrl-Shift-V with an application other than LR as the active window and see if it moves. I suppose Ctrl-Shift-C might also play into it so try both of these hot-key combinations with a program that isn’t LR.
If none of this sheds any light on the situation, then give a more detailed description of the low-level functions you’re doing to accomplish the copy-paste of settings, so someone else could replicate the steps exactly.
Specific detailed steps, like:
left-click on source photo’s thumbnail in the filmstrip
press Ctrl-Shift-C to copy the settings
click Check-None
enable the white-balance and calibration checkboxes
click Ok
left-click on destination photo's thumbnail in the filmstrip
click on Settings / Paste Settings in LR’s menus to paste the settings to the selected photo

Dual monitor setup and intel help

Hello
I am trying to set up and dual monitor setup here, with a monitor and a tv, the monitors resolution is 1680x1050, the tv's resolution is 1360x720, which results in that the desktop will have an resolution on 3040x1050.
When I try to do this with GNOME's xrandr gui, I get this:
required virtual size does not fit available size: requested=(3040, 1050), minimum=(320, 200), maximum=(1920, 1920)
When looking in the motherboards manual, it states that each out of my graphics card can do a resolution of 1980x1080. Is the intel driver missunderstanding something? Since both the dvi and hdmi output only delivers 1360x720 and 1680x1050, 3040x1050 is only an virtual resolution.
Any suggestions?
