Hello everyone, the LCD screen of my Dell Precision M4800 changes continuously contrast (based on what is on screen) when in battery mode. I work with photos and graphics and this behaviour is unacceptable.
Serching on this forum I found causes and solutions, but none actually works for me.
Causes (found on this forum):
- The problem seems to be caused by a Dell Laptop display behaviour (in fact I can't see this issue on my girlfriend other-brand laptop running the same Win 8.1 os)
- The problem seems to be related to power saving management (it shows up only in battery mode)
Solutions (none works for me):
- Disabling Display Power Management in the Intel Graphics properties solve the issue (this is indeed true, but I disabled in the bios the Video card switch because I want to use only the nVidia Quadro K1100, so this solution doesn't apply to my case).
- There should be an option somewhere to disabling a feature called "Dell Intelligent Display" that seems to cause this issue, but I can't find it anywhere (it should be in the Dell Power Management but I can't find it!)
I need help because I can't work with my Dell workstation in battery mode due to this really bad issue.
