Dejvik Choosing display profile M32QC results in same colors as Current Monitor
This is because apparently the same profile is used.
Dejvik I did download a driver for the monitor from the gigabyte website, could that have something to do with it?
Could be.
You just need to match the Affinity profile so that the colors are similar to Godot.
Just for info: yesterday I bought an AOC AGON PRO AG276QZD OLED monitor.

Looks like it's the first batch in our northern palestines. The paper at the bottom is the Color Calibration Factory Report. This used to be an attribute of professional monitors.
There is absolutely no need to worry about accurate color reproduction in indie games. It is very laborious (taiga, jungle), expensive and does not justify itself. It is enough that the colors were at least remotely similar.
