PWM and flicker-free LCD displays on Librem notebooks?

Wow! Thank you very much, @nicole.faerber , this is a very unexpected (and GREAT!) possible solution.
( Replying to your post in the other thread. )
Can someone test here?

I’ll test on my ntb, but dont have librem yet.

A few questions arise:

  • will the HW allow the changes?
  • then why wouldn’t the manufacturer set the better (higher) freq already?
  • what are the implications of rising the PWM frequency? higher power draw of the display?
