I recently build a pc, a pretty good One. And bought a 1440p 144hz Monitor Should definitly Not be under powered. Turning it on works Great but when Eber i Drag a Windows of Anything there is a very clear screenthear and i dont know Why. I havent connected it to the Internet yet but i dont think that will change anything. The Monitor Gas Free Sync and Supports v Sync and yes i habe a amd graphics Card 5700xt to be exact. So is there any driver i have to install First or is it a mechanical Problem.
