I’ve got an Acer ed242qr where the left half of the screen has a strange color shift. I tried disassembling the unit and reconnecting all cables with no change. I don’t think the issue is with the panel because I powered the monitor up with one of the main board cables unplugged and the monitor cycled through a red/blue/green full screen and those colors seemed perfectly normal. Is this likely an issue with the main board, cables, panel board or other? I have no idea where to begin with this. Here’s a photo of the issue: https://imgur.com/a/kARt3bS
Hi @cdaly , Have you tried adjusting the monitor’s colours using the OSD menu > color > 6 axis hue or 6 axis saturate to see if you can resolve the problem? The pure red, blue, green may have been OK because when testing these colours only the appropriate colour pixel i.e. red, blue or green would have been turned on whereas all the colours are made up of a combination of the 3 colours at different power levels i.e. a pure white colour = 100% red, + 100% blue + 100% green. Here’s a link that shows the % ratio of the three colours for most of the common colours. If you can’t fix it by adjustment most likely it is a solarization problem with the mainboard (assuming it hasn’t got a tcon board - board between mainboard and screen) that feeds that half of the screen.
