Whenever I am doing something that has a dark background, my main monitor automatically dims itself. At first I thought it was dynamic contrast, but it's not turned on. I also tried disabling sensor monitoring service, but to no avail. The problem seems to only happen to whatever monitor I set as my main. So if I set my second monitor as the main one and open up a video with a dark background, only that monitor dims. I've been trying to figure out what's wrong for a few days now, but nothing seems to work. I sent BenQ an email regarding this problem, but all they responded with was an RMA request. If possible, please help.
Specs:
- Windows 10 64-bit
- i5 4690k
- 8 GB RAM
- Asus Z97-A
- Two BenQ GL2460 monitors
- AMD r9 290x
- 1 TB WD HDD
- 120 GB Crucial SSD.
How can I get my monitor brightness to remain constant?
