L450 - Windows 10 - Adaptive brightness problem - Display dims when dark image on screen

2016-06-16, 11:04 AM

Hello!

 

I have a Lenovo L450 laptop with Windows 10 (upgraded from Windows 7 a few months back). Since upgrading to Windows 10, I keep on having the same problem with the display brightness. Every time the display shows a dark image, video (or similar), the display dims a lot and I am not able to increase it with the function keys.

 

For example: when watching a rather dark YouTube video in full sceen, the display dims A LOT and I can not increase the brightnes with the function keys. As soon as I exit full screen, the display VERY SLOWLY returns to normal brightness and now the function keys work again. After exiting full screen the display is still so dim that, when you press the DECREASE BRIGHTNESS funcion key, it INCREASES its brightnss.

 

See photo attached.

 

PLEASE HELP ME AS THIS THING IS DRIVING ME INSANE!

 

Thanks a lot!

 

Marko
