Fixed my monitor. My BenQ monitor had an annoying delamination on the left side, an encroaching noticeable white area (when the screen was white). I tore it all apart and noticed a section of the defuser panel was sticky and transparent in a spot. I cleaned it and the glass and just put Scotch tape over that area. It's not a 100% better but probably about 85% better. It's a small miracle I got it back together working and looking better. Quite surprised. :)
