Go to SolutionDell Precision 7540 - brightness is not working
I have just one (but BIG) problem with my new Precision 7540 - brightness is not working, at all. When I press Fn + arrow down or up I can see that scale of brightness is changing but it doesn't effect the screen. I have try to change brightness in BIOS, but still no effect on the screen. I have updated all I can. I've try also on BIOS 1.0.0 and 1.1.3 - no effect... It hurt my eyes (brightness is very strong now). Only "Night light" works.
Win 10Pro - version 1909, OS build 18363.476
UHD Graphic 630 - driver version 26.20.100.7262
Nvidia Quadro RTX3000 - driver version 26.21.14.4128
BIOS - 1.3.3
Procesor i9-9980HK
How they can sell so expensive workstation where basic feature is NOT WORKING !?!?!
Any idea how to fix this problem? Thanks in advance.

Same issue here too! Except mine is stuck too dim. Any solution?
The brightness bar moves but no change in the actual brightness.
I saw a DELL fix that said to check for duplicate monitors in device manager, but I don't have any.

Resolved the issue by reverting to an older Monitor driver
