7370 adjusting brightness on light backgrounds
Hi all,
I have a 7370 and the auto brightness is doing my head in. I know I solved this before but its since had a new mobo and a reinstall.
The problem is when switching between light and dark things on the screen the brightness adjusts, its NOT a case that it adjusts based on ambient light
I've been through everything on this thread which seems to be quite comprehensive!
I've been through everything in advanced power settings, intel settings as well as the registry hacks.

Thank you, doesn't look like there is a patch for this unfortunately :(
It is definitely Content Adaptive Brightness Control, and so far, I've not found a solution.

This is a feature called "CABC". Dell does not advertise this feature anywhere but you get to find out about it after buying the laptop after which you have no recourse except to hope that dell releases a fix for it. This same feature exists in the XPS line for which they have released a fix. They haven't yet for this laptop, nor there is any communication that they plan to. When I contacted dell I was told that it's working "as designed" and basically to deal with it. I own the 7373 and facing the same issue.

Sounds like this could be Content Adaptive Brightness Control, which is separate from the more typically discussed adaptive brightness (which varies based on ambient light) and Intel Display Power Saving Technology (which washes out colors to preserve battery life).
