i notice that some people complains about "gamma" issues in some games that people here do/develop.
Said taht i post bellow a link that you can check and of course re calibrate your monitor according to mainstream "gamma and color " monitors, so you can deliver your games without being to dark or too bright
The website is very user friendly and requires no advanced knowledge, you just need to adjust your monitor according to best comparison to the site page panels.
in my line of work i have do deal with RGB, Adobe , Fogra , and others color profiles, parring industrial printing machines DSLR cameras and stuff , with my and other monitors and with a lot of shit issues
That, you all do not want to know
But again this site has a simple way to deal with "color correction" issues
Hope it's useful
