Windows 10: multi monitor issue - screen staying black

So I have 2 monitors connected to an rtx 2070, one via hdmi (4k) and 1 via displayport (1440p). I mirror the screens so both display the same content.

This usually works, however for reasons I can not isolate one or both monitors show only black screens sometimes at random. This is always after a period of inactivity, for example when I leave the computer on and go out for a bit. Sometimes I can leave it all day and the problem does not happen.
On the 4k monitor the screen will not return until the computer is reset no matter what, on the 1440p screen the display will not return sometimes until a computer reset but other times pressing ctrl alt and delete causes the display to instantly resume operation as normal. No other button combinations seem to do this.

I have disabled all power saving settings, there is no screensaver enabled, sleep and hibernation are disabled and the cables and monitors are not at fault. I have also reinstalled windows and there is no change to the situation.

Any ideas?

Hi Frank,

Thank you for your interest in Windows 10.

I understand the you have tried to resolve the issue and tried many steps. I really appreciate your efforts in resolving this issue. As you have mentioned that switching the cables make both the monitor
work so I believe its not the driver issue. I would suggest you to try connecting another cable and check if the issue persists.

Below is the Microsoft help article on How to connect a second monitor/ Multi monitors.

Note: The steps for Windows 8/8.1 applies to Windows 10.

Hello,

Thank you for posting your query on Microsoft Community Forums.

I would appreciate, if you can provide us the following information to help us understand the issue better?

What is the make and model of your system?

I would suggest you to uninstall and reinstall Graphic card drivers and check.

Uninstall and re-install the Graphic card device driver

a) Press “Windows Logo” + “X” keys on the keyboard.

b) Click on “Device Manager” from that list.

c) Go to Display adaptor and expand it and you would see the Graphics Card device, right click on it and then select “Uninstall”.

d) On the un-installation window, if you have an option: “Delete the driver software for this device” you may select that and then remove the corrupted drivers from the computer.

e) Follow the on-screen instructions to complete it and the restart the computer if prompted.

After the restart, go to the Device Manager again by following the steps mentioned above and then click on the “Scan for hardware changes” button. Check if Windows detects the Graphics Card device and installs an appropriate driver automatically.

If it doesn’t install the driver, I would suggest you to go to the manufacture website and install the latest graphic card drivers.

Hope this information is helpful. Do let us know if you need any further assistance, we'll be glad to assist you.
