GTX 970 - Dual Monitor Black Screen in-game

pmmarcino · Jul 24, 2018

Hello, I have a problem which I fight over a year - getting black screen on second monitor while in-game (in furmark after 1 sec.)

GTX 970 G1 Gaming
398.36

What have I done during last year :

- Change system Win7 -> Win10 and Win10 -> Win7 (still problem)
- Clean, reinstall drivers
- Install older versions of drivers (seems working a lil bit longer but doesn't fix the problem)
- Install drivers without GExp
- Bought a new mobo (GB Aorus Z370 K3 Gaming)
- Bought new CPU (i7-8700k)
- Bought new PSU (Seasonic Focus Gold 80+ 550FX)
- Switching from fullscreen -> windowed
- Disabling desktop comp.
- Disabling scaling
- I think i tried everything

Both monitors are VGA. One VGA->DVI second one VGA->HDMI/DP (doesn't matter - in both case problems).
Problem even exist when i plug-in my 1st monitor to CPU Intel GPU and 2nd one still in GTX.

Problem solved when i plug-off 1 monitor or when I downgrade my card spec to almost zero in afterburner (but still cant play fullscreen)

How to live ? ... GPU works perfectly on high spec when using only 1 monitor ...

I cry everyday and night please help ;(

The monitor that's not in use should go to a black screen, specifically when you're gaming in full screen mode. When you're in full screen mode, you're telling the system to only focus on that screen that's playing the game, so the computer will make the other monitor go black.

I have 3 monitors, some games work well across all three at 5760x1080 resolution, some games don't. The ones that don't, I still play them on full screen at 1920x1080 and when I do, only the center screen has the game on it. The left and right screens go black.

The only game that I play in windowed mode (not borderless window) is LoL. I actually play it at 1680x1050 resolution so the window fits nice into my center monitor. I then have the left and right monitor to do other things - usually I'll have some movie/video running on one and the other has a web browser open so I can check things out while I'm waiting for matches to start.

I'm on Win 7 with a 980Ti. I'm not sure on the driver, I haven't updated it in a while so it's probably something from 6+ months back.

I would suggest you try playing a game in Windowed Mode and set the resolution a step below your monitor's native resolution. So if you're monitor is 1920x1080, try it at 1680x1050.

Both monitors go black screen, only hard reset helps.

I must downgrade spec with afterburner to even play in widowed mode ...

My mistake, I misunderstood the exact issue you were trying to explain. Since you've already replaced/upgraded a bunch of hardware, perhaps it's time to look in a different direction a bit.

Do you have access to a different video card you could try on your computer? Any GPU from the recent years should be able to connect to multiple monitors - heck, even my paltry GT 730 can connect two monitors to it.

Or do you have different monitors you might have access to test with that utilize something newer than VGA connection?
My three monitors support DVI and HDMI connections, so I have mine connected in such a fashion:
1 via DVI
1 via HDMI
1 via HDMI w/ DP adapter

No i don't have any other monitor/GPU

Everything works perfect with only 1 monitor no matter which adapter i use dvi/dp/hdmi.. Ultra settings etc ..

VGA is analog.
DVI is digital.

I think you can only get one signal to convert to VGA. The one that goes from DVI (on the GPU) to VGA (monitor) should be easy enough with how you're already connecting them. It's the other monitor you're trying to connect that is causing the problem.

If you're forcing the system to convert both signals from the GPU from digital (DVI-D) to VGA without an active converter, that could be your issue. You may need to get something like this (https://www.amazon.com/Cable-Matters-Adapter-Converter-White/dp/B007SM7O2U ) for the second monitor to convert from HDMI (GPU) to VGA (monitor).

I'm not saying this will fix your issue, but it's the only thing I can think of and I don't have any way to test it myself to verify.

What if the problem still exists when i plugin 1st monitor to CPU (INTEL) and 2nd to GPU (NVIDIA) :>
Btw. I have 2 adapters like this u posted - One HDMI second DisplayP

Without more hardware to test with (spare GPU or different monitors) I can't say there's much more you can do. Getting a spare GPU to test might be the easiest thing for you - do you know anyone that has any kind of GPU you might be able to borrow? If not, you're kind of stuck.

I'm strongly leaning towards the fact that you're trying to run two VGA monitors off the card and it's having issues with it. I'd suggest getting monitors with newer video outputs, but it's a hard idea to push upon you when you have working monitors (as long as you're not connecting them both at the same time) right in front of you.
