I've had my AW3418DW for a year or two now (since June 7, 2018) and it's an amazing monitor. I've been blown away by the color depth and the absolute clarity of colors. AFTER Nvidia color management, I know this monitor has no gamma controls but I feel I may have gotten an extremely off panel. Out of the box and for other things, such as my PS4, the colors are extremely green and washed out. I've tried recommended TFT settings and different profiles but the only way I can get this monitor to look as good as I know it can is by heavily modifying my colors via Nvidia control panel. I have to turn down a lot of the colors and gamma individually until I can get it looking as neutral black and white as I can. Without this, it's entirely washed out and the whole screen looks green, even the monitor's OSD looks green, and with other panels I have seen of the same model the OSD is supposed to be blue/grey and I've tried everything I can within the monitors settings alone besides using a calibrating hardware as I have not been able to buy one.

TLDR, is my panel a dud, or is there something I can do to fix this?
