Ignorant's question: isn't it sending the signal because it has an incompatible resolution? External can display it but internal can't?

Nope, it’s generic 1024x768. With no external display I get black screen, but if I press keys to switch output I can bring game back to laptop screen, but this end up with low fps or app exit.

Okay, after some experiments I found that when laptop screen works in its native resolution (1400x1050) I’m constantly getting black screen when I launch games. Any games.

But if I set windows to other resolution, 1024x768 for eg, games will launch fine.

They also launch from windows sitting in native resolution if I set aspect ratio correction to centered, not the full screen stretched.

It was a resolution issue 😀

No idea what's going on. Both games and windows support different resolutions, but only if i sit in native one it can't display games. And it's only on custom drivers. No logic here 😀

I've been trying to make my life easier, with this issue, but still no luck. I made a quick resolution switch, so i could enter 1024x768 when i wanna play games and get back to 1400x1050 when i'm done. But even in windows, if i switch resolution fast, sometimes i get black screen and only by pressing output switch button i can get back the image.

I wonder what works wrong here.
