Display changing brightness issue

I’ve noticed that when my laptop gets a tiny bit of direct sunlight (specifically in my case in a moving car for the past few hours) , the screen adjusts/changes it’s brightness. This is great and all, except it makes the screen quite a bit blown out. The light/white objects on screen can be a bit hard to make out.

I disabled automatic brightness changing in windows 10, but that doesn’t seem to change the screen’s behavior? I’ve identified the brightness sensor as the small light grey hole next to the camera (as when I cover it the screen goes back to normal)

Any suggestions?

Annoyingly, Intel has a setting called “Local Adaptive Contrast Enhancement” that they enable by default in their driver. You can open the Intel Graphics Command Center, click in the display tab, and then turn it off:

Does anyone know how to access the Intel graphics settings from Ubuntu? I had already replaced windows 10 with ubuntu when I noticed this issue.

@Anna_Ordog does turning off “Automatic Brightness” in Settings > Power fix it?

Thank you so much @jeshikat! My screen was practically flickering every time the ambient light level changed slightly, and this fixed it!

You make my day @nrp thank you !

Really just wanted to come in here and say thanks @nrp this was tripping me up and I couldn’t figure it out. Some of Intel’s display decisions just confuse me, such as the contrast adjustment to save battery life, which makes bright sections slowly dim and stuff.

I also noticed when looking for a similar issue that the display changes the brightness that there is another option in the intel graphic control center for toggling adaptive brightness.

Can’t wait for the AMD mainboard.

Thank you so much for the fix!

Sorry, I’m resurrecting this thread in mid-2024, but has this setting changed location?

I have a Framework 13 Intel 13th Gen and this is happening to me.

But when I go to the Display → General section in the Intel Graphics Command Center, the settings list is looking pretty bare.

Yeah, that just opens the Display Settings in Windows 11, but I don’t see anywhere to disable this adaptive contrast feature.

I don’t want to turn off Adaptive Brightness, I want to turn off Adaptive Contrast. One is adjusting the brightness of my screen, which is fine. The other is adjusting the colours of my screen which I don’t want.

My original screenshot shows that Lighting Aware Contrast Enhancement isn’t in my list of options. That is the specific setting that I am wanting to disable, but it is not under Display → General as @nrp initially showed on the first reply to this thread. That was the whole point of my original comment on this thread.

I’m wanting to stop the contrast from changing when the light sensor detects a high amount of light.
