Hello!
I've been having this issue for a a couple of months, never had the time to work on it and made it work yesterday by installing the newest pack of drivers for my GPU (21.5.2) but undid what I did yesterday by installing the previous pack of drivers (21.4.1) because War Thunder wouldn't start...
The HDMI cable works, I used different ones, just to see if it was indeed my HDMI cable, they all work with my laptop, so it can't be the cables.
So yesterday with the 21.5.2 pack of drivers I had image via HDMI on my projector and was happy about it, so I started watching movies again. Today I tried to play War Thunder and an error was shown, unfortunately I didn't make a screenshot of it. So I installed the 21.4.1 pack of drivers again and was able to open War Thunder again and play it normally but had, like before, no image on my projector. As a test, I installed the 21.5.2 pack of drivers (latest) and here's the interesting thing: War Thunder runs with this pack of drivers (21.5.2) but now I don't have image on my projector.
