I haven't played any games for a while on my PC. Recently, though, I upgraded my CPU, RAM, and motherboard so I decided to test the new CPU out. Almost every game I have tried is having the same problem. If I run it anything higher than 1080 @ 60hz I will start to see white snow/static on the screen. It will just be a flash at first but it will gradually get worse. Then it turns to a green screen. Alt-tabbing out of the game usually fixes it but it starts again as soon as I get back into the game. There are a few older games (like AoE 3 and Half Life Lost Coast) that don't do it even at the higher resolutions but it seems that every newer game does it (Metro 2033, Shadow of the Tomb Raider, Battlefield 3 and 4, Witcher 3). I've tried different drivers. I've tried reseating the GPU. I've tried different HDMI cables. I've even tried putting the card in a different slot. I haven't tried a different monitor, yet. The only other 4k monitor I have is my TCL TV. I'm gonna drag my PC into the TV room on my day off and try that. Has anyone else had this problem? Anyone find a fix for it, yet? The only thing I can think of is that it's the VRAM and I'm only noticing it at the higher resolutions because it's not filling up at the lower ones. But, then again, if I run the games at 4k and lower the refresh rate to 30hz, the problem goes away. It only happens at higher resolutions AND higher refresh rates combined. The monitor is a Westinghouse 50" 4k TV that I got on sale two Black Fridays ago, if that helps. Edit: I should add that the display is fine in 2D. It's only in games that it happens.
