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 problem

Having a problem setting up dual montors.
http://www.microsoft.com/windowsxp/using/setup/learnmore/multimonitor.mspx Followed everything at this link and everything went fine except a few things.
1st. The comp, was responding really slow and/or not responding at all.
2nd. The comp, takes a big performance hit per 1st problem.
3rd, How can i get explorer to work on the other monitor (secondary)like it shows on the primary one.
Also one monitor is a 19" Lcd and the secondary monitor is a 17" crt, i'm plugging the crt into the dvi-i port with the dvi-i/vga adapter, i also tried dragging items from one screen to the secondary but didnt work Any ideas on what to do to make this setup perform better, Thank you, DOK

OK here goes for everyone that has said to use drive cleaner my hat is off to all, I'm an idiot for not listening or paying attention, so if your reading this and saying noob, ding dong, dummy or what ever i deserve it, many apologise. Well i have fixed above problem and downloaded a fresh copy of 81.98 and used drive cleaner as per instructed and guess what to my surprise, the system works great, per Tiresmokes referall i have posted new results in the section that was suggested, Thanks DOK

HP Pavilion p6240f Dual Monitor setup problems

My HP Pavilion p6240f desktop has two on board monitor conections. VGA and DVI. Can I connect two monitors to my computer? My operating system is windows 8. Only my VGA monitor is working. Only one monitor shows up in Device Manager.I also tried using detect in display settings. Please help

dighaysus,
Yes, your HP Pavilion p6240f Desktop Computer can support two monitors at the same time. One monitor must accept a VGA analog signal and the other monitor must accept a DVI-D (HDMI with adapter) digital signal.
Please provide the brand and models of the two monitors, so we can determine if you have a supported configuration.

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?

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.

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 MBA 2013

Hello Everyone,

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?

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?

Firefox doesn't always play well with a multiple monitor setup and hardware acceleration.
Try to disable hardware acceleration.

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

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 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

Separate workspaces on dual monitor setup?

Sorry if I leave out any details -- just ask if you need anymore.
A little background information before I begin: I am using 3.12-ck x86_64 kernel, using Cinnamon, and have a dual monitor setup via one graphics card, which is an NVIDIA 560 Ti, and I'm using nvidia-ck-bulldozer
I'm trying to have each monitor have its own Workspace instead of just being one large desktop, but I'm not exactly sure how. The only solution I've found so far is:
1) Right click the panels on Monitor #1 and choose "New Panel" -- (This is where my problem lies; there is no "New Panel" option)
2) Then hold Alt and click and drag the new panel to Monitor #2 -- (I also cannot even move my current panel from monitor via clicking + key combos; I have to change the primary monitor in Cinnamon System Settings)
But, as I said, this solution doesn't work for me. What exactly should I do?
Edit:
Forgot to mention, I'm using Cinnamon version 2.0.14

I am using the same version as you right now, but I couldn't find out what you are searching for. I think this is because this feature doesn't exist yet. See https://github.com/linuxmint/Cinnamon/issues/130

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 .
