When I watch youtube, I like watching gaming videos. When the screen moves, the has these noticeable lines like a cut in the video. When the video is still or not looking around, then there are no lines. It only started happening when I got a 1080p monitor. It's very annoying. I am using a GTX 1050ti graphics card connected with HDMI. It doesn't happen when I play games or scroll through a forum or such. Only video playback. If I watch the video in windowed mode, it doesn't happen. Any help will be appreciated.
