My monitor goes like 70% dark from time to time example when I open Irfanview but I have not loaded a image yet it goes like 70% how do I fix it so the monitor never goes dark??
I do not have f.lux installed I have only had this computer like 3 1/2 months and I never had this problem with any other computer I have had. It is only happening with programs that are black when first opened.
I just updated the video card driver and restarted my computer it is still doing the same thing. IMHO it is acting like the computer is going into a power save mode.
Try a different monitor, different cable, possibly video card. Check your installed programs to see if there is anything that may do this. If there is, it would bug the hell out of me.
What brand of monitor do you have? I had a similar issue, mine is an Asus, there was a setting that was causing it, I think it was eco mode or something similar.
