Hello everyone !
This is my first post in the toms-hardware so sorry if I'm good at this business :D
So I have a SAMSUNG SyncMaster P2370MS(I know its kind of old) and It works well,Until I change resolution in a game like CS:GO for example.
If I play the game on native resolution then I choose 1080x1920.
Thing is,I play CS:GO on 1024x768 because its better for me...
When I change it to 4:3(from 16:9 obviously) and choose 1024x768(or any other resolution that is 4:3) then everything looks grey.
The best way to describe it is-as if you look at the sunlight and it looks good,then you put sunglasses and it loses the color,now imagine the same thing but the main menu(and the rest of the game) looking grey instead of blue(CS:GO's main menu for example)...
Does someone know how to fix it ?
Merry Xmas and Happy Hanukkah everyone !
