Sorry to not detail that much.
I can't see different colors on my pc, like red, orange is more like yellow, i can see dark green, but not neon green. I can see blue and purple too. Some colors got changed into white/black.
I'm sorry that I can't really describe what is going on. I noticed that my printscreen didn't work because other people can see it normal.
I didn't press any buttons on the monitor.
Can anyone help me? I'm kinda scared to System restore cause i never did something like that.
