The lower part of my screen is updated one frame earlier than the upper part. I was able to isolate the error to the HDMI output of my laptop. The screen or cable is not broken, as I don’t get these errors with other connected devices. I am assuming it is some hardware defect. Does anyone know what it could be and how I could fix it? Here are a few pictures that show the problem: pixelfed
Solved: Ok, it seems to have been a software problem. That had to do with the sync. I have installed ubuntu on the laptop for now and everything works again. Some update seems to have shot something. I am now using a LTS version.
Very weird looking tearing, but if you are playing 24, 25, or 50 FPS content on a TV or monitor that is locked to 60HZ it is going to tear, some handle it better than others.
I suspect your output is set to 60hz or something and you are watching content that isn’t at either 30 or 60 and your playback software isnt doing autoswitching (kodi, plex etc do this, but not web browsers or apps like netflix)
So it’s not a hardware fault, its just the reality of watching media on a computer with an external display, so it’s a software configuration problem.
Also, considering the severity of it, are your video drivers up to date? that amount of tearing is close to what you’d see when running standard vesa drivers like when you have no video driver installed at all.
