Black Screen on Display Capture WITHOUT two GPUs

Higgs · Jul 10, 2020

Hi,

I'm using a desktop computer equipped with an AMD Ryzen 9 3900X CPU and an Nvidia RTX 2070 Super GPU. I'm running the latest versions of Windows 10, the Nvidia GPU drivers, and OBS Studio.

When I try using "Display Capture", I get a black screen. The advice given on this thread doesn't apply for me, since I only have the one GPU - the Ryzen 9 3900X doesn't have a built-in GPU, so there isn't an issue of OBS Studio seeing the wrong GPU. Still, I am getting a black screen. I can see my mouse moving, but nothing else.

Any ideas how to solve this?

Thanks in advance!

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Check that you don't have any programs running that are known conflicts. Also, run OBS as administrator.

Higgs · Jul 10, 2020

Thanks. Already tried running as Administrator and it didn't help. I have never used any of the apps listed there except MSI Afterburner, but I uninstalled it and nothing changed... Any other suggestions? :(

carlmmii · Jul 10, 2020

Do you happen to have Hardware Accelerated GPU Scheduling enabled? That is currently causing all sorts of issues with captures, and should be disabled currently.

Higgs · Jul 10, 2020

I disabled it (and restarted). Now something weird is happening: I see a black screen, but if I press record and minimize OBS Studio, it does record my screen - except it only records the desktop wallpaper and taskbar, not any open windows. If I open a window, I can see the mouse move as I click on various things in the window, but the window itself doesn't appear in the recording at all. Tried this with several different apps. Weirder still, OBS Studio itself appears on the taskbar when I open it (i.e. there's a button with the window title), but other apps don't appear on the taskbar, as if I did not open them at all! (They do appear on the actual taskbar, just not on the recorded taskbar.) WTF..?

carlmmii · Jul 10, 2020

Really not sure what would cause this. @R1CH might have some insight into this behavior.

What happens if you revert to a previous GPU driver version? (anything pre- 451.48)

Higgs · Jul 10, 2020

Reverting to older version doesn't help, nor does changing between the Game Ready and Studio drivers.

Higgs · Jul 11, 2020

Update: Disabling HDR solved the problem! OBS Studio is now working without any issues. Is HDR support planned to be implemented in the future?
