I have been having this problem for a while now. I am using 2 monitors, one is using a VGA connection and my main screen is using an HDMI. When I load up my computer all of the colours are really dark and horrible and I have to change the resolution in the control panel of Nvidia down to a frequency of 59Hz refresh for the colours to return to normal again. This wouldnt bother me as much if it only happened once, but after I load up a game or close down a game or program which requires full screen mode the colours turn horrible again so I have to carry out the temporary fix after loading up every program which is very frustrating! I would really appreciate it if someone could help
