Laptops and Notebooks with Panels not using PWM Flicker

[mtbvfr]

Hi Everyone,

Please post the Brand and Model Number of your Laptop or Notebook if its Display Panel does not use PWM (Pulse Width Modulation) to control the dimming of the backlight.

For those of you not familiar with PWM and the problems it can cause, please read the following article.

I honestly can't imagine not using PWM for dimming, especially in a laptop. PWM isn't the problem anyway, it's low frequency PWM that can cause flickering.

The Thinkpad T520 with the base 1376x768 screen circa Oct 2011 does not appear to use PWM. I am also looking for new laptops without PWM but information is sparse.
