Graphic Cards :: Triple Monitor Setup (Display Port)
Jul 25, 2014
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 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.

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 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 recently broke the screen to my asus n56vz. I ended up removing the whole top panel and removing the inverter cord.
I plugged in a external monitor and it worked fine at first. When i restarted i noticed that it starting running hotter and displayed a second option on a 768p monitor. My 1080 aoc was made the main display seen though its not the first monitor its second.
I tried to delete or disable the second monitor but i could not. What should i do?
I used to have 33c temps idle and not its 50c. It used to display only the external monitor. Now it displays 2 and the 2 is my main.
I dont have any recovery or 8.1 disks... I tried a refresh and it said "missing files" so i cant even do that...

I just purchased a new windows 8 PC. I was attempting to hook the computer up to my tv through hdmi (the pc has no VGA input) and when I went through the normal paces to put the display on my tv (display desktop only on 2), the signal did not transfer and there is no display on either my tv or pc! how to revert the display back to my pc monitor without being able to see anything? Acer support was less than useful. It's an acer aspire z3-605 all-in-one pc.

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.

I have a Lenovo Flex 14 - win 8.1 (64 bit).I have restored my pc and after the recovery the option to adjust the display brightness has "disappeared". The option is no longer in place in the charms bar or in Power Option and the adjustment keys (F11 and F12) are not working either.

I just upgraded to 8.1 and now a game that I play called theHunter wont launch. When I run the launcher it comes up with an error saying 'No Appropriate Display Modes'. It was working fine on Windows 8. The support at the Hunter hasn't been very useful and despite trying a number of different things I can't seem to solve this issue.

I'm having a terrible time after reformatting my 8.1 machine (desktop).Every time I try to adjust a display setting, such as gamma, some other process overrides it in real-time. Meaning I can't calibrate my display in windows color calibration, or even in my nvidia control panel, it instantly resets it while you're adjusting the slider. I don't know what this could possibly be, but I've uninstalled the Dell display manager, so I assume it's not the monitor overriding it. I also have nvidia control panel set to 'use other applications' for display configuration.

I use Windows 8 on a rMBP, but frequently use an external monitor that's 1080p. Since it scales 200% for the HiDPI of the rMBP, it's way too big on the external. Is there a way I can have it scale only the internal monitor, and leave the external one at 100%?

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 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?

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.

I know how to select the second screen options, however, my Surface Pro and our Samsung Laptop both running Windows 8 cannot detect a second monitor/screen. We are connecting via the HDMI port, but it will not display no matter what option we choose nor whether we run it from the desktop or apps. This is what we use for work to display presentations for clients.

Original error message: "Display driver NVIDIA Kernel Mode Driver, Version 314.22 stopped responding and has succesfully recovered"
I'm getting this error again and again, mainly in games. (Which seems logic, they use the graphics card most) Games without DX11 will continue after a black screen has occured, but at very low FPS.
Games with DX11 will just crash and stop working after the same black screen.

Both primary and secondary displays are 1080p, native. Windows says both are running at 1920x1080, but I can visually see the secondary display is running a lower resolution. The GPU is GeForce GTX 560M, with the latest drivers. I didn't have this issue with Windows 7.

My problem is that I can't change resolution on my laptop's display with win 8. It's quite an old, Toshiba Satellite M70. I installed win 8 directly from XP. Everything is working fine except this. I tried to install the old drivers in compatibility mode, but says the system requirement is not enough. Do I have any chance to make it work?
