I'm using a Sapphire HD 7950 with an Asus VG248QE connected via DisplayPort running @ 144Hz and a Samsung 225BW connected via HDMI. When I try to stream via Twitch in the AMD Gaming Evolved program OR if I watch hardware-accelerated videos on EITHER monitor, I get screen corruption on my Asus VG248QE monitor. Sometimes it'll get to the point where the computer locks up completely and I have to manually reset. The corruption does not appear on the Samsung monitor. This used to happen in Firefox with YouTube videos, but after I disabled hardware acceleration in Flash, it hasn't been a problem while browsing. Here's a video of the corruption in action: https://www.youtube.com/watch?v=85QNj0-SHL0 This has persisted across driver installs. I haven't tried a reformat yet, but that might be the next step. Was curious if anyone else had experienced anything like this?
I guess you are using intel QuickSync for encoding. AMD Gaming Evolved is likely using GPU. Edit: Have not even realize it was bot message. (semir) To OP, try to take GPU clock to 1050/1000MHz and vram to 1375MHz. As Compute tasks use parts of GPU more intensively than gaming.
