PWM on the 4k screen of thinkpad x1 yoga Gen 5

2020-07-04, 22:13 PM

Hi guys,

 

I wonder whether the x1 yoga Gen 5 use PWM to adjust the brightness of the screen in the 4k screen model (When you see the screen by your phone camera, can you see the moving lines?).  

I know in the x1 carbon gen 7, they use PWM on their 4k screen and cause headache after long time use.

 

like this 

Someone can help? thanks

First,Nobody can see your privacy video.

 

I guess, your UHD panel manufactured by BOE.

when brightness setting <99%,this panel use PWM.

so you can see flickering on your phone camera.
