Hello VanishingBlaze! Do you see the lines everywhere? Or only in videos? Because I can't see any lines in the screenshot you provided.

Only on video. It should be noticable around the guys face. It's kind of hard to tell but it's there and I haven't found a solution. I thought it was my tv but I used another browser and it didn't show up

After a closer look, those lines seem to be caused by compression of the video. There is nothing we can do to fix those lines. I hope this helps and if it does, please mark this post as solved.

I thought something was wrong with the video as well at 1st but then I tried another browser and those lines didn't appear. I know i'm probably the only 1 with the problem or just able to notice it. I just don't know whats causing it

That are artifacts caused by Firefox downscaling the image. The lines disappear once I look at the image in its natural dimensions and reappear if I zoom out. Firefox is always not very good with downscaling images.

How would I fix this? My zoom it at 100%

This specific image is 1360x768 if I inspect the image in a tab. If I display the image with these native dimensions then I do not see these artifacts.

I put my monitor into 720P (what the video was label as) and that seemed to help, but the screen is blurry altogether when I do that. So there is no way to fix this unless I use 720p?
