I have a Windows 10 Dell XPS 15 (9530) laptop which is working fine except for the fact that when plugged in (not on battery) the screen dims whenever I view a dark image/content on the screen.

Note that the screen brightness does not change when ambient lighting changes in the room (I already turned off adaptive brightness from the Control Panel). The issue is that it changes when I am viewing dark contents/images (e.g. viewing a nighttime photo, or visiting a website with a dark background) on the screen. This is a big issue for me as I do a lot of video and photo editing and I need the screen brightness to remain the same at all times.

I seem to be having a similar issue as highlighted in this post:

Screen Brightness Changes Depending on Screen Contents - how do i turn it off?

However, those solutions don't work for me (including turning Display Power Saving Technology off from within the Intel Graphics Properties). Any advice would be greatly appreciated.

Many thanks in advance.

  • Do you have "DELL Premier Color" or "DELL True Color" installed? – Yorik Dec 13 '17 at 18:15
  • Nope, I don't... – user2347540 Dec 13 '17 at 18:46
  • I think the term to use for narrowing your search is "Dynamic Backlight Control" or "DBC." it is deifferent than the windows powercfg setting. Dell has firmware updates for other XPS models ( dell.com/support/article/is/en/isbsdt1/sln304876/… ). Doesn't look like it is exposed for the 9530, but perhaps you can dig up something. Post and accept your answer if you solve it. – Yorik Dec 13 '17 at 19:05
  • it might be exposed via either gpu driver interface... – Yorik Dec 13 '17 at 19:06
  • No problem, thanks for following up with the solution – Yorik Dec 14 '17 at 15:26

I actually solved the issue by following this link and downloading all firmware updates for my laptop model:
