How do you completely disable adaptive brightness on Windows 8?
Have a Thinkpad x120e; upgraded to Windows 8 last week and have tried EVERYTHING to get rid of this craptastic adaptive brightness.
The screen gets brighter on a white backdrop and slowly dims on darker images. I feel like I'm tripping when I'm reading articles online.
Yes, I've turned adaptive brightness off (battery and AC options). Yes, I've tried every power plan. Yes, I created my own power plan, through the Lenovo "power manager" and through Window's "control panel." Yes, I've optimized the display, I've updated the driver for the monitor. I've done everything. Even spent an hour chatting with Microsoft support (who basically said nothing is wrong and restart my laptop). I swear this thing is going out the window if I have to deal with the damn labile brightness.
Your Intel graphics chip is probably the culprit, a setting called "Adaptive Contrast Enhancement"
1. Search for and launch "Intel Graphics and Media Control Panel"
2. Click Advanced and click OK
3. Media -> Image Enhancement
4. Uncheck "Adaptive Contrast Enhancement" and "Film Mode Detection" then click apply
That should fix your problem.
If your problem is with the brightness on your laptop changing randomly when "Adaptive brightness" is disabled, here's the solution:
1. Launch "Power Options"
2. Cover your light sensor (small lens somewhere near the keyboard)
3. Wait for your screen to dim
4. Drag the "Screen brightness" slider all the way to the right while still covering the sensor
5. Uncover the sensor
That seems to reset your brightness to max regardless of if the sensor is covered.
