Multiple Monitors Detected & Utilised When Only Have 1
Jul 9, 2009
I have a new machine that I have installed Windows 7 64bit (build 7100) and am having issues with the system detecting and selecting as my primary display monitors that dont exist.
I am running 2 Gigabyte GTX275s in SLI and have a Samsung 2443BW LCD via a single DVI cable. Nothing is plugged into the other connectors.
I wouldn't usually care if there were other disconnected displays being detected but my problem is it seems to randomly detect a range of monitors at each startup and pick one to be the primary display leaving my monitor blank. The screen will flash 3 or 4 times making the windows sound when you connect new hardware.
I have tried another monitor and get the same result. It is quite frustrating when you have to reboot the system often 3 times before you can get a desktop (an extended one still) so you can get to the display properties and make corrections that dont seem to last after a reboot. I have tried both the 186.18 and 190.15 Nvidia drivers.
Sometimes even into either the change the screen resolution or nvidia control panel will sometimes cause it to refresh all the monitors it detects and i can be left with a blank screen.
I hope I have given enough detail for someone to be able to assist.

I have attached a second monitor to my laptop which runs Windows 7, however, I need to set different resolutions for different monitors, because the display does not fit to fill the screen on both monitors.
It is also noted that the display is replicated, and I would like to have the effect of having different desktops e.g. being able to use different applications such as debugging code on one monitor on an IDE such as Visual Studio, and, viewing the browser on the other monitor.
Currently it does not seem possible since the behavior seems to be that the same resolution is replicated on both monitors.

Maybe someone can help me. I have a GTX295, and my main monitor is plugged into the right plug while my TV into the left. For Nvidia the right plug (when facing front of the computer) was always considered Monitor #1, for what ever reason...
The strange thing is that these new Nvidia drivers seem to mess things up... Although While booting the post shows only on (2nd plug) which is monitor 1, while in Windows it detects it backwards... It detencs 2nd plug as monitor 2. Does this make any sense?? It's really annoying. Is there a way of changing this?

I would like to setup 2 monitors on my computer. I know my computer is older but it is very fast and I don't plan on using the monitors on resource hogging stuff
My specs are:
Intel pentium 4 3ghz HT ENABLED
4gb ram
1tb hdd
Nvidia gt 520 1gb
windows 7
My monitors are 2 different inputs / outputs
If I just plugged them both in to the plugin on my gpu would it work and have to adjust stuff? I have never used dual monitors so I don't know. One monitor has a 1600x900 (I plan on this being main monitor)
Other is 1024x768. One of them is dvi and other is vga.

I do currency trading from my home, and need to have a full screen dedicated to each currency I trade, each screen/currency running off the same PC at the same time. I know I can attach multiple monitors to my Windows 7 PC, but am not sure how to have the same program running simultaneously on 3 different monitors (that's the only way to get the 3 currencies to show as a full screen and have the ability to submit trade tickets independently based on respective currency). Seems as though the same image will appear on each monitor.Is this at all possible, or will I have to buy 2 additional PCs to put Monitors 2 and 3 on to accomplish this?

So I recently found my copy of Battle for Middle Earth 2, and decided to give it a whirl for nostalgia's sake. Only, the moment I get into a game, I'm met with a glaring issue - I cannot scroll across the map in one direction, because my mouse simply moves onto the other monitor.
So, what I have tried, is fiddling with the resolution settings on the game itself - no change. I don't have the option to run it in a window, or move it to my other monitor to see if it persists there. how I might be able to fix this, short of just disabling the other monitor during gameplay?

It seems like a few programs, such as Adobe Photoshop CS4 and Adobe Dreamweaver CS4 (seems to be limited to Adobe), expand past my main monitor, and reach the monitors to the left and right.
This happens when the programs are maximized.
I've included two screenshots of this issue. Notice the additional black border around the main screen (middle one).

Just installed Windows 7. and everytime i start up a game (like left 4 dead)
all screens go black(like when they do when you set a other resolution) and back to normal resolution. when game resolution isn't different from the desktop resolution. and cause i ussually have a series running on one of my other monitors i can't see them cause well desktop thinks it not on its desktop resolution(or for what ever other reason it is that video won't show on second monitor if there is a game up on your main monitor that is not on ur normal desktop resolution).
this doesn't happen with every game though and can't really figure it out. if u need any info, or have no idea what i'm talking about(don't really know how to explain this very wel) post for more details.

3 Viewsonic 22" monitors and one Dell 24 inch monitor all running DVI cables.
I have three of the video cards in the computer to run multiple monitors. Windows 7 has a feature where when you plug in a monitor, it auto detects it and then enables it and sets its proper screen resolution. The problem is that when I plug in more than one monitor, I get inconsistent results.
Here are some examples:
Example 1 that happens: I have two monitors plugged in and I plug in a third monitor. It enables it within Windows 7, but the monitor does not actually turn on. If I restart the computer, somtimes it will stay enabled and boot up with all three monitors on.
sometimes when I reboot it, it again shows all three enabled but only two are actually on. This happens also when I plug a fourth or fifth monitor on. Sometimes two or three monitors will be on whereas one or two others will not be on but will show enabled in display properties.
Example 2 that happens: Sometimes when I plug in a second, third, or fouth monitor, it will actually show an additional monitor as disabled. For example, if I have three monitors plugged in and it shows three monitors enabled (regardless if all three are on and working), and I plug a fourth monitor in, then it enables the fourth monitor, sometimes it turns on, sometimes it doesnt, and it also shows a "generic non-pnp monitor" as number FIVE.
Even though only four displays are plugged in. I've seen this happen even if I plug in a third monitor (shows four, with 3 or number 4 disabled). If I try to enable that FIFTH "ghost" monitor, and click apply, it says "cannot save settings." You can see an example of this as an attachment.
When I plugged in another monitor, it shrunk 2 and there is also a 5 the same size but disabled. Strangely enough, the 2 says the pnp monitor and 5 says the model number of the monitor. However, enabling 5 does not actually enable it and says that it cannot save settings.
I have tried downloading the latest drivers from ATI 9-10 as well as Catalyst Control Center as well as Hydravision from ATI and also Ultramon multiple monitor software. I have tried deleting the ATI 3600 drivers WDDM 1.0 (maybe 1.1) from device manager, only to reboot and then it installed the drivers, reboot again and it brings back all of the whacky settings.
I have a couple of times got all four monitors enabled and all four monitors on where the cursor moves across them properly. EXACTLY what I want to have happen. If I restart it almost always comes back on as EXAMPLE 1 where only two of the four monitors will turn on, but it shows them enabled in display properties, or if all four monitors do come back on, they are not in the same order that I had them in and it actually shows FIVE in display properties.
To make this all even stranger, believe it or not, i've even had it boot and one of the monitors is BLACK & WHITE. What is so strange about this is that the Windows 7 logo when booting, the color Windows 7 logo, is indeed COLOR on that screen, but once it is actually in Windows 7, it is BLACK & WHITE.
If I do a restart, it sometimes comes back in full color. What this means is that there is color while Windows is loading, and then once in Windows one of the monitors is BLACK & WHITE throwing out the possibility of a bad video card.
Has anyone else experienced anything like this? Is there KNOWN issues with Windows 7 and ATI video cards or drivers? How about Windows 7 and Viewsonic or Dell monitors? This is extremely frustrating and looking for some guidance on the subject matter. I believe that the drivers, whether Windows WDDM default or ATI's are simply not correct with Windows 7. I never had this problem with Windows XP.
PLEASE See "win7_monitors.jpg" file to see what I am talking about concerning EXAMPLE 2.
Edit: I need to add that on example 1, where it shows enabled but the monitor does not come on, I have noticed that about 50% of the time when I put the Windows 7 into SLEEP mode, and take it out, the monitor(s) that were off are now on.

I am trying to get my wife's new computer up and running without any BSOD or program failures. Note that the system was not initially set up to capture the dmp files so all the earliest ones are missing. I presented the initial problems to the original seller who recommended sticking with MSE and uninstalling Norton 360 and I did that. Another forum suggested that Virtual Memory was the problem and I disabled and restored VM. Still having multiple crashes and I am hoping that I can get real help here. I do note that all the crashes have ntoskrnl.exe in the driver stack although sometimes alone and sometimes with other drivers.[CODE]

We have three medical clinics and the front desk staff float from clinic to clinic depending on their schedule. I only started here a few months ago and I am working on upgrading their Dell xp systems to Windows 7 systems.The problem begins to crop up when say a user named Sally will come in and sit down at this system for the first time.. Well, she needs to login, click on outlook icon, let it find her exchange PST and copy settings to her user profile, then she launches the application for the scanner that she uses to scan in ID's and insurance cards for every patient coming in.. The scanner is set to default settings and needs to be tweaked on color depth and double sided, etc.. Then after that, she needs to launch her Medical EMR application.. and then choose various options in the citrix client, ..TL;DR - Each user needs to spend 20 minutes resetting the defaults at this updated system.
Well this is fine except, I am planning on updating 2 front desk systems at each clinic, the user Sally will need to do all these things EACH time she finds herself sitting down at a system I just swapped out the previous evening.My thought is this, put a single system down in one clinic and let it sit a week giving most of the float users a chance to work on it for a day, setting all of their preferences etc.Once I get a bunch of them with user profiles on the local drive, grab an image of that drive and just deploy that to each system I roll out..Couple issues I am running into:First would be that I would have to register each Windows 7 copy with a new serial, which I have The next issue is, we have a mis-mash of Dell optiplex systems. 330's - 380's even a couple 320's..

I have been getting a fairly random blue screens and I cannot pin point it myself. I know a bit about diagnosing and repairing issues but this one is just a pain in my butt. I am uploading the dump files and I hope someone can give me a hand I am running a sfc scan right now to test for any problems too. Also got this off the TSG SysInfo Program.

I'm having a bit of trouble trying to get two monitors, a small 1024x768 LCD, and a 46" 1920x1080 TV, to display the same wallpaper at different resolutions. My graphics card is older, a Nvidia Quadro FX 1700, but it is perfectly capable of driving both displays at the same time. It's a minor annoyance, but I'd like to get it working if it's possible.

I've got a setup that is running 2 ATI 5850s with dual monitors. I tried to add a 3rd monitor but when I do, I get the error message "to extend the desktop, a desktop or display must be disabled". Basically it's only letting me run 2 at a time, any 2 works.I've got 2 monitors using the DVI??? (whatever the white port is) and one using HDMI. I have tried running all 3 from one card, and I've tried doing various combinations using both cards and I can only get 2 monitors to run.

I'm thinking of having 3 monitors. Right now I have two, and my setup is so that the desktop scales across both so I can just drag a window from one screen to another.
If I put in a second video card and setup a 3rd monitor, will it scale on over one more time? I'm not sure how to set that up since I've never seen it in person before.
Any ideas on how that would work? I currently have an 8800GT that's got the two hooked into it, and I'm planning on getting some other cheap nVidia card just for the 3rd monitor. I just want to make sure it will scale on across to the 3rd monitor as well.

Has anyone here had experience with 3D monitors? I've just seen on Engadget that JVC are launching a 46" 3D HDTV for around $7,000.
I'm really excited for when true 3D content really takes off
I started a PhD on autostereoscopic monitors just a couple of years ago, which is a type of 3D display that doesn't need any glasses to view 3D images (but has some drawbacks compared to polarised displays, like the JVC one above).
Most nVidia graphics cards are capable of displaying many existing 3D games on a 3D monitor/TV without much extra configuration. So you could be playing Flight Sim, Team Fortress or other 3D games quite easily in true 3D
Admitedly, it's more novel than useful for many games - but flight sim is amazing in 3D. I'd love to have a setup like this in my living room!

This problem started a few months ago when I updated the video drivers on my NVIDIA card. What happens is that when the pc goes to sleep, either by my command or after timing out for inactivity, the pc will wake up when prompted by mouse or keyboard, but the monitors don't. I know the pc wakes because when tapping on keys or clicking the mouse button I will occasionally hear pings from the pc. I'm not convinced that the problem is NVIDIA's, but this does coincide with an updated driver of theirs.Ultimately, in order to get my machine working again I have to press the power button and restart cold. Also, and I'm not sure if this is worth noting, upon cold start, my Kaspersky and clock gadgets, which are normally placed in the upper-right corner of the right monitor, display in the left monitor somewhere off-center.
I'm diligent with keeping drivers updated, but I really have no idea what to do now.

I have a HP dc7900 desktop computer (Intel E8400 3 GHz, / GB RAM with windows 7 ultimate x64).
I would like to use 4 monitors. I have a nvidia 8800 GTS in the PCI-e slot. This card is so big, so I cannot insert an other card to the second PCI-e slot.
If I try to enable the onboard VGA card, the windows won't boot up.
So I bought a nvidia 6200 64BIT PCI card, put it to the PCi slot, but the same happened.

Since I am a musician, I must practice at home and with the modern hardware it became impossible to have total silence in the room, specially a small one. Tried everything an after all, my solution was radical but very effective: My cpu is in my living room with my LCD TV and a keyboard and mouse and, after drilling a wall, I have a LCD monitor, keyboard, mouse, USB hub and a USB CDRom in my studio.
This is perfect because I have total silence to practice and a Home Theater PC in the living room. Under windows XP using the NView software I was able to create a hotkeys combination(ctrl+y) that allowed me to switch monitors without any confirmations, right clicks or dropdown menus. Just click those two keys together and that's it. Now, not even a MultiDisplay Wizard is available.
Sorry for writing so much, but here is the question: How can I switch monitors like I use to do? Is it possible to create a shortcut or hot key or, in a worse case, use the usual way in windows seven but in a way that a confirmation is not required? When I change resolution asking to show only in one of the screens I must run to the other room the confirm the change.
This is the main reason I did not install Vista, but I hope it will be a solution in Windows 7.

I am a new Windows 7 user and so far I really like it. I had XP before and I recently bought a new computer. I am trying to set up triple monitors like I had before. The three monitors are as follows:
1) Acer 19" widescreen #1
2) Acer 19" widescreen #2
3) 40" Sony Bravia LCD TV
I had this working fine on my old computer. I had the two monitors plugged into an added video card, and then the TV plugged into the motherboard. On this new computer, I have one graphics card with all three monitors being plugged into it (one through VGA, one through DVI, and one through S-Video.) I get the two main monitors to work properly, but I can't get windows to extend the Desktop to my third monitor (My TV), like I had before.
When I go to the screen resolution option, it recognizes all of the monitors, only it will only let me select two to actively use. I would even be satisfied if I could get the second AND third monitor to show the same thing. Does anyone have any suggestions as to what I can do?

I have dual monitors, one on my laptop and another bigger monitor for when I am docked and at the office.
Under XP I had it set so that when I closed the lid on my laptop, the lapto screen was shut off and all files that were subsequently opend were opened to the main big screen.
It appears now that when I close the lid the screen stays on and if there was a window showing on the laptop when the lid is closed it does not automatically switch to the big monitor. It used to under XP. Is there a way to duplicate this behavior in Windows 7?
There are times when I want to use just one monitor and shut the monitor built-in to the lap top - off. Is there an easy way to do so?

I have an external LCD monitor connected to my notebook via HDMI. I’d like to be able to turn off the laptop screen or make it go black or run a screensaver ONLY on it, while I’m working/watching a film on my external display. Going into my notebooks settings and toggling from 2 displays to 1, works but is not a process I want to do as frequently as I’m having to do now.
Basically I’d like to be able to turn on and off (or blackout the screen or run screensaver) my notebooks display, as quickly as possible, while not effecting whatever is going on, on the external display.
