Graphic Cards :: Single Monitor Detected As Multiple Monitors?
Feb 17, 2013
I have just rebuilt my PC and decided to make the jump from Windows XP to Windows 8. The jump has not been smooth, but it looks like I have ironed out my biggest problem (incorrect installation due to not creating a system partition therefore Windows 8 = no DVD, no boot; rookie error).
Now I am stuck with an issue - windows detects my only screen as more than one. Sometimes it thinks I have two, more often it thinks I have 3 or 4. Installing the current nVidia drivers did not work.
What I have at the moment is 2 generic non-PnP monitors and 2 generic PnP monitors detected, according to device manager. nVidia control panel calls them Dell SX2210, VGA display, (i can't recall the 3rd one, I'm on my laptop now), and TV. Windows display setup calls two of the SX2210, and the other two are either generic non-PnP or PnP monitors. In nVidia control panel it looks as though I have a clone setup (2 screens enabled) with the Dell SX2210 and the VGA display. In windows display setup it looks as though I have a clone setup (2 screens enabled) with Dell SX2210 and generic monitor.
I have repeatedly unchecked the secondary monitors in both nVidia control panel and windows display setup, leaving me with what should be a single monitor arrangement and 3 disabled monitors. This works until I restart my computer, which then reverts back to what it was before. This is OK as a workaround most of the time, but sometimes when I boot up the computer it detects the wrong screen as the primary and I get a monitor which goes to power save mode. The solution to this is Win Key + P and change the display selection while blind, which works now I know how. Sometimes my screen will refresh (installing programs or drivers) and I get the same result. Detect displays also results in no signal to my monitor.
Currently using DVI from the graphics card to DVI on the monitor.
CPU: Intel 3570K (stock clock)
MB: ASRock Extreme4 Z77
RAM: 4 x 4GB 2133 GSkill
VIDEO: Gigabyte GTX260 OC
MONITOR: Dell SX2210 @ 1920 x 1080
OS: Windows 8 64bit
*Yes I know the 260 is an older card, it has come from my old system for economics reasons (to be upgraded later), but it was working perfect on that machine.
I've been looking at some of the MATROX graphic cards for multi-monitor output -- up to 8 possible !!
Now any decent software to run these -- the standard software seems OK at running TWO monitors but I want to be able to run several more. You can run more but it gets a bit complicated managing this from within the standard windows system itself.
Five Best Tools for Managing Your Multi-Monitor Setup
I have a brand-new HDCP supporting monitor (native resolution 1920 x 1080,) on which I play the latest blu ray movies from the computers built-in blu ray drive, and a 9 year old flat screen non-HD plasma TV (on which I watch You Tube, BBC iPlayer and 4OD, streamed from the PC via a VGA cable,) both connected to my GT610 NVidia graphics card.
It seems I can only get them at the same resolution. My desktop does however have it's own on board graphics processor. Is it possible to run these two devices at different resolutions? (Since the ancient flat screen can only handle resolutions up to 1600 x 1200.)
I was having some problems with my dual monitor setup and while messing around with the settings I am afraid I messed it up a lot worse than my previous problems were. To keep it short, one of my monitors was not popping up (it ended up being the cable), but when I was in the settings I clicked the monitor to pick a "unknown device" as it was never detected. Now, when my computer boots up the main screen is the "unknown device" and the secondary screen is one of my two monitors. Because of this my screen only launches up as a blank gray screen. Typically one of my screens show this, while the primary one gives me the option to put in my password to login. Because this monitor which is my main monitor does not exist, I cannot get to my login screen. I know I am still on dual monitors because it will let me run the cursor off the screen as it does when I am using my monitors.
Basically, I want to boot up not on extended and only on my monitor (I tried the Win+P but it doesn't work on the gray screen). I also tried booting up in safe mode, but was unable to access it with Shift F8. Any simple solution to this before I have to do a reinstall of Windows 8.
In a few weeks (I can't wait! ) I will replace my laptop with the Surface Pro.
Right now, though, I have my laptop connected to two monitors: One via VGA and other via DVI. I'm running Windows 8 Pro x64, so this all works great.
So the big question is whether it is possible to have multi-monitor support via the one-and-only DisplayPort that is on the Surface Pro? If so, what--if any--additional hardware would I need?
When I'm docked at home and using my Surface Pro as laptop, I really need to keep the functionality of using both external monitors (one is 31" and the other 29"). I would really hate to go back to only being able to use one.
I just installed the Windows 8.1 Preview 64-bit last night and am loving the improvements over Windows 7 Pro 64-bit!!! I am running it on a Dell Optiplex 745 Tower.
My only problem is that my ATI FireGL V3100 is not being recognized by windows at all. I checked in the device manager and it doesn't even show up. I currently have a monitor hooked up to the card and it is working fine. Unfortunately, AMD doesn't have a driver for Windows 8. For that matter it didn't have on for Windows 7 either, only a Vista driver, but it worked fine in Windows 7. Same thing with the Dell drivers, worked for Windows 7, but not for Windows 8, even though the drivers were for Vista 64-bit.
I am wanting to hook up a second monitor, but when I do, it doesn't even detect the second monitor. All it does mirror the first display onto the second monitor. I looked into the Screen Resolution settings and even tried clicking Detect. Nothing. It found my first monitor, a Acer AL1916. Even when I unplug the Acer, it thinks the other monitor, a HP LP1965, is the same thing, it doesn't change the name of the monitor. I even tried going to HP to get a driver for my second monitor and installed that, to no avail.
Here is the problem... everything boots just fine and runs with 2 of the GPU's installed. I have the latest AMD 13.12 drivers, and the AMD APP SKD installed. When I add the 3rd GPU though, windows will auto detect it as a Radeon 7900 with the caution sign, AND/OR a r9 200 series card, also with the caution sign, most times BOTH. Then it randomly freezes the system. A couple of times I got it to run long enough just by luck I guess, to install the 13.12 drivers on the 3rd GPU, but then in a few minuites the system would freeze again.
2 GPU's run just fine, the problem only shows up when the 3rd card is installed, and it happens on any of the 4 16x slots, or both 1x slots on the MOBO. It doesn't matter if the GPU's are directly on the MOBO, or on 1x16 risers. There are plenty of folks running this set up with up to 6 GPU's, so I know it can be done, but I must be missing something somewhere in the windows set up.
-Running my PC with a Radeon HD 7700 on Windows 8, main display is monitor in DVI port, secondary display is HDMI running to my LG TV for playing videos (only enabled some of the time in AMD Catalyst Control Center under "Desktop Management>Creating and Arranging Desktops")
-Normally, I enable the 2nd desktop (my TV) through the HDMI output of my video card easily. However, about a week ago I ran into an issue: while the OS detected the display, it only recognized it as a monitor in 640x480 resolution.
-I tried several things to fix the display issue, but was finally successful by changing the HDMI cable connected to the TV side to the second HDMI port on the back of the TV (that is, going from HDMI 1 to HDMI 2). This fixed the issue immediately.
-Good till yesterday. Now the HDMI 2 is no longer detected as a valid display. HDMI 1 (the original connected port) is still detectable, but it's still having the 640x480 max resolution issue (and no audio output as well).
-HDMI 3 on the TV currently works, but that is the final HDMI port on the TV, and I don't want to continue moving the cable without resolving the issue. I have tested the TV HDMI 1 and HDMI 2 ports with other hardware, and they seem to be working without fault with a DVD player or Media box, so I doubt the issue is surrounding my TV.
Last night my laptop (running Windows 8 x64 with a secondary monitor) was working fine. I put it to sleep and when it woke up this morning the secondary monitor is flickering a lot like this:
I have tried uninstalling the AMD driver and restarting then installing the latest version but it still doesn't work. The screen even flickered when the AMD driver was not present. I connected the monitor to another laptop and it worked fine.I played about with the refresh rate in the catalyst control center and it ended up making the laptop screen flicker instead so I reverted the settings back.
I am running Windows 8 on a Samsung 350V5C laptop 6GB RAM.
I'm struggling connecting to a second monitor, the problem being my laptop connects OK VGA to VGA but doesn't stay connected. After 5 seconds i get the disconnected 'beep beep' then it immediately reconnects and again after 5 seconds disconnects again. I did get it to stay connected the other day so i know it works but is was pure luck and just trial and error, however, when i went to connect again i got the same problem, also when it did stay connected i just got 'duplicate screen' when i just want 'Second Monitor Only'.
Here's what I did: Control Panel > Hardware & Sound > Display > Project to a second screen, then i have tried all 4 options PC only/Extend/Duplicate/Second only and i get the disconnect then reconnect every 5 seconds again.
Do I have to change any other settings, either on monitor or laptop?
I have 3 monitors, BenQ RL2450, two of them via DVI and one via HDMI.
Issue, HDMI connected monitor goes black every now and then. Not really a pattern in it. Sometimes it can flicker black once every 5 min, sometimes once every 30 minutes. Monitors are ok, checked with other computers, cables are OK, tested on different monitors and HDMI on TV.
I am suspecting drivers, so did a complete uninstall with graphic removal tool, then installed latest WHQL and beta drivers, still the same. Seen several users with the same issue, but no solution.
Graphic card keeps 40-50 Celsius while gaming, so that's not the issue.
Just can't remember back when I did not have this issue, hasn't been there forever.
All monitors on 60Hz, and with the same resolution.
Have a 32" HD TV which I use as my Primary Monitor(connected using HDMI) and a Lenova 17" as a Secondary (connected with vga cable). I shut the desktop down, unplugged the 17" to use on another pc. When I reconnect the 17" to my main desktop it now does not pick up
I have seen some posts on internet, concerning connecting an external CRT Monitor with a Laptop computer. They pretty much said that there might be a blue cable with, and one can use it to connect that monitor with laptop. Now I am confused that mine monitor has two cables; one of which is blue and the other one is white, having three larger pins inside. Both these wires are connected to my desktop CPU. Now my question is that, it is obvious that the blue wire can be connected to my laptop but what about the other one, this wire is connected to the power supply of my desktop pc, and when it comes to laptop, would mere one wire (blue) suffice for the electricity or other things?
My friend's new Sony laptop has an external monitor connected via HDMI. When he restarts the computer, about half the time the external monitor is not getting a signal, it is blank. He then restarts it until it works. I've only connected remotely to it, and I've been able to get it to go on by playing with the settings in Display properties. Possibly if I was in front of the computer I could try Fn + F5 to see if that works, but he is the kind of guy who does not want to press keys to make it work, he wants it to just work. What might be done to make the second monitor get a signal on a more consistent basis?
I have three monitors setup in Windows 8. Two of them to a Radeon 4670 and the third to the onboard HD graphics 4000. They work quite well in Windows 8. When I upgraded to 8.1 the HD 4000 monitor no longer comes up. The adapter is recognized and device mangler says it is working and has the most recent driver.
This is important to my work flow and is just one of a number of things not to love about 8.1. I would like to get this functioning before I tackle less important issues. Win 8.1 is installed on a test drive.
I am running Windows 8.1 preview and whenever I play certain games my monitor locks up and my GPU fans stop and the only way for it to work is by restarting my PC. I don't think my card is defective because I was able to run the game once until it crashed. I am running on 32 bit if that makes any difference. And I don't believe it overheats because I keep MSI Afterburner running the whole time. This also happened on Windows 7 32 bit.
I have a laptop with one VGA port but I wanted to connect it to two extra monitors so that I could create a triple monitor system. I bought a VGA splitter to be able to connect all monitors but what I discovered is that it still recognizes it as a second monitor. I have the screen on my laptop extended with the second one but I cant extend the second one to the third one. It just duplicates it. Is there any way I can download software to make it recognize the third monitor?
I bought a new laptop without OS, it's a XMG advanced with i7 4700MQ CPU, an Intel HD grafics 4600 chip and an NVIDIA geforce 765M GTX.
I installed win 8.1 and updated all drivers. The laptop itself works fine. Now I wanted to connect an external Monitor ( HP w2207h) The laptop recognizes that there is an external Monitor and that it is an HP w2207h and tries to extend the desktop to it, but the monitor itself says that there is no input signal via the HDMI input and it goes to sleepmode.
When I connect my old Laptop to it, it is no Problem, the monitor shows the extendes Desktop, so the monitor an all cables are OK. (old Laptop : Win7 core 2 duo CPU geforce 9600M GT )
With the new Laptop I have the same problem, when I try to connect it to my LG TV set via HDMI, the Laptop recognizes the TV and tries to extend the desktop ( I can move the mouse out of the internal display to the TV ) but the TV says there is no input signal.
I have set the Output to 60 Hz and different resolutions and tried to duplicate the display or only use the external one. Nothing worked.
I can't force the Laptop to use the Gforce, he decides which one he wants to use.
A friend bought the same laptop and made the same installation, but when he connects to his external moniotr everything is fine, but I don't know what kind of monitor he has and I have not connected my laptop to his monitor.
I power up the PC and monitor, i can see the POST on the monitor, and the windows 8 loading, then my monitor starts to shut down for 1-2 seconds, its not a complete shut down, like you change resolution or refresh rate, then after 1-2 seconds i can use my PC normally.
I uninstalled my nvidia drivers, and i don't have anymore this problem....
I booted windows 8 in safe mode, and i don't have the problem....
My gpu is a gtx680 and a XL2411T monitor, with dual link DVI cable...
I have a new Dell XPS with Windows 8. I was just starting to use it when I tried to explore bringing up a second monitor. For some reason the system doesn't recognize the second monitor. I then accidentally selected "second monitor only".
now I am without any monitor. When the system boots it recognizes the primary monitor (DVI) but then goes off to look for the second monitor. My system has AMD DVi video card as the primary video. The other video port is VGA, but I cannot get any monitor I have to work from it.
Is there a way to reset the video selection without having to use the mouse to navigate to the Devices selection?
My dual monitor system has been working fine since new several months ago. The other day, I started experiencing a problem upon startup or reboot: The left of my dual monitors would be blank (no picture). After switching the monitor off and back on again (sometimes more than once), the picture would appear. No further problems during session. At next reboot or startup the blank screen recurred. It is not consistently blank every time. and It almost always now takes two times of switching monitor off and on again for image to appear.
I suspected a bad monitor so i switched the cables on my AMD Radeon HD 7700 graphics card. The left monitor is still the one where the problem occurs. So it is not a bad monitor.
I have tried deleting devices, reinstalling drivers, to no avail. I cannot find any options in Windows 8 for additonal options after trying everything under options/display.
I currently have a 15" PC with a 3200x1800 resolution. Using Windows 8.1. I have the scaling to highest.
My 2nd external monitor is 1920 x 1200.
I am trying to extend my desktop to the 2nd monitor but is there a way to use different scaling for both the PC and monitor?
I have unchecked "use scaling for all my displays" but no matter what, I still can't change the scaling on the external display. It uses the scaling settings of my PC (scaling set to highest because of 3200x1800 resolution) and because of that, the monitor scaling shows everything large.
I am on a laptop with a gtx 765m. I am trying to connect a thunderbolt port to a display port monitor. My understanding is that thunderbolt is backwards compatible with display port. But, for the life of me I can not get it to work.
I am using a minidisplay port -> display port cord.
I have ended up hooking the monitor up with an hdmi cord for now. FYI the monitor is a 2560x1440 monitor if that matters.
Well I have been having issues with my monitor. I had a Toshiba laptop I had hooked up to my monitor, everything worked great. It then crashed, I got a new Dell with Windows 8 64bit and Intel graphics. I have an HDMI to VGA adapter cause my laptop doesn't have a VGA port and monitor doesn't have HDMI. So I hook it up and get it to work but "Input Not Supported" was floating around the screen.
So I changed the resolution. The only resolution that makes the "Input Not Supported" to go away is 1600X200. Well its clear picture but I have the annoying black bars on the side of my screen. I have looked around and everyone says to go to the CCC but I can't find it on here and from what I understand that is for AMD only(if I'm mistaken how to make it work cause I have attempted it). So is there an Intel version or how do I fix it?
So I recently bought a new computer. I was using the GTS 450 on the old one no problem not even a month ago. I have attempted to install it on my new pc. Switched out to a Thermaltake TR2 600W PSU which is operating just fine. I placed the video card into the primary pci slot and powered it with the 6-pin connector. Put everything back together and started her up. PC turns on fine, with even the fan going on the video card. But no video output. I'm stuck. What can I do? The drivers won't install themselves without the hardware.
So I'm running 2xR9 290X (crossfire) with 3xQnix Qx2710 monitors. One of the qnix monitors was purchased with HDMI/DisplayPort connectors along with the usual DVI connector (normally these monitors only come with the D-DVI input)
I had a 2 monitor (with just the two DVI-only monitors) setup for a while that was working fine.
Since installing the third monitor I'm experiencing several weird things:
- On boot, until the Windows login screen comes up (Windows 8.1), there is nothing on the non-primary DVI monitor (so my setup is my primary monitor is one of the two DVI monitors, and then the left and right monitors is another DVI-only and the DP monitor).
- If the monitors go to sleep, or I put the computer to sleep and wake it up, any windows that were on the non-primary DVI monitor are moved over to the primary DVI monitor. Windows on the DP monitor do not move in this configuration.
- Within CCC, after sleep / monitors off, I have to restart CCC's control of the color settings for the non-primary DVI monitor. (I'm forgetting what the actual button says, but it's the button under the Display color controls settings where you can manipulate the R/G/B channels - I have to use the GPU for color matching since the monitors don't have any inherent ways to change R/G/B levels
If I only connect the two DVI monitors this is not an issue.
If I connect one DVI and the DP monitor, after sleep/wake any windows that were on the DP monitor are moved over to the primary monitor (again, note that this didn't happen when all 3 monitors were connected).
I have tried the newest version of CCC, as well as the current beta version - same behavior in both.
I have tried using HDMI instead of DP - same behavior
Aspects of this sound similar to the issues discussed in this post : [URL] ......
What I don't understand is why the second DVI monitor is acting so oddly when all 3 monitors are connected. Why would there be no picture when the computer boots?
I am running Microsoft Office Home & Student 2010 on Windows 8.1 Preview.
Yesterday, I had to purchase a new desktop PC monitor. It's a Samsung S22C300H .
The resolution is higher than my previous monitor. As a result, when I open Microsoft Word and have it display in Print Layout mode, the page has shifted from the center of the screen to the far left.
(The resolution on the new monitor is 1920 x 1080.)
I've been used to the page being in the center of the screen for the past 20 years! I've lowered the resolution, which did center the page in Word, but the resolution is nowhere near as sharp as the high resolution mode.
Is there a way to get the Print Layout page in Word to be centered on the screen in this high resolution? If so, what is the procedure?
I have a game (ATCSimulator 2) that is not written for widescreen. The game tells me that in order to work in the mode I want the display must be set to a standard 4:3 setting. It gives the options of 1280x800, 1440x900 or 1680x1050. I tried to do this, but apparently my video card does not support any standard resolutions. I thought it might just show the screen stretched, but the game will not even go into the mode I want to use.
How I can change the resolution to display properly or possibly a workaround for this?
