I recently noticed that a column of pixels on my TV was becoming more and more noticeable. I did some research and it appeared that a column of pixels was simply “stuck.” I stumbled upon UDPixel and figured I would give it a shot, as the alternative is to purchase a new TV. It works by flashing the primary RGB colors as well as white and black. I ran it for about 2 minutes and it seemingly fixed the problem.
