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
default connected 1600x1200+0+0 0mm x 0mm
1600x1200 0.0*
1280x1024 0.0
1024x768 0.0
800x600 0.0
640x480 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.

I hope I've provided enough information. Thanks in advance.

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!

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 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...

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.

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.

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?

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 .

HP Pavilion dv7-2250ed and dual monitor setup

Good evening,
Currently I own a HP Pavilion dv7-2250ed notebook using a dual monitor setup (notebook display + extra monitor)
I wondered if it would be possible to hook 2 monitors to this laptop? (notebook display + extra monitor + extra monitor)
If this causes the problem, the notebook display isn't requered.
Also, if not, is there a dockingstation for this brand which supports the above?
Kind Regards,
Cor van Noorloos

I have attempted to connect one monitor via HDMI and the other one via the VGA interface.
Using Windows 7 OS and "default configurations" (Control Panel\Appearance and Personalization\Display\Screen Resolution) it is possible to use both external monitors as desktop. However the laptop screen will go blank. So at any time it appears to be possible to have an extended desktop with only two screens.
- Does HP have any drivers/solutions that make it possible to extend the desktop from "Mobile PC" display to two additional desktops?
- Has anyone tried third party software (e.g.. UltraMon)?
- Is there a technical restriction (e.g.. Videocard capability)?
- How about using a Linux OS (e.g.. Ubuntu)?
- What external Hardware exists that would enable me to extend my desktop to three or more monitors simultaneously?
Many thanks in advance.
It's the graphics card and the number of physical connections available. You might have 3 connections (notebook display being one) but the graphics card likely does not support more than 2 monitors. Intel graphics only support 2, however you may be able to find some AMD chips that will support more however that would be a major upgrade.

Captivate and Dual Monitor Setups

I am running a dual monitor setup and it seems captivate does
not play too well in this environment. When i record a project, i
select the window that i want to record which is our software
product that is open in full screen. Resolution on the monitor is
1024x768. Id i click the button for Snap to fit, it does not snap
around the program, it captures some of the second monitor and the
Recording size shows 1032x746. I am unable to record a project in
1024x768. Anyone else have this issue??

I have dual monitors and capture on it frequently. I'm not
sure I've had
the problem you describe, but I almost always just set the
size manually
(which maybe I do because I had problems with the auto
settings).
So I select Custom Size the resize the red border to my
monitor settings...

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 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?
