Hey, I recently bought this monitor and I have one red sub pixel in the bottom center of the screen. I already tried some tools on the web to fix it, but nothing changes. Maybe I need to do it a bit longer.. It is only appearing on a white screen or on colors without red (like green) in it. Overall I found no other issues, only minimal backlight bleed, but no scanlines, dse, dust etc.. Do you think it is worth the hassle to RMA it and maybe get a more faulty one?
