How do you stand a brightness that high? I have mine currently set to 45%. :OTo those unhappy with this monitor out the box.
I got mine this week and it's now set up right next to an Acer 1440p 144hz IPS. Out the box it looked worse, it was definitely oversaturated.
Try using the ICC profile from the Rtings.com review. All I did was apply that and up the brightness from 75% to 80%. Made it look 10x better and is now the colours are slightly better than the Acer, but it also goes MUCH brighter so is overall a much better looking monitor. For entirely accurate colours for photo work etc you've probably chosen the wrong monitor, but the colours do look fantastic for regular activities and gaming.
