Flicker free / No PWM backlight laptop
Hi,
For some reason, the screens with LED backlights that use PWM for dimming, produce me severe eye strain and nausea. It's not something usual, but it seems I'm not the only one with this problem.
My question is if Dell produces any laptop with a screen that doesn't use PWM. Ideally with 15" display but 17" would be acceptable too.
PWM explanation: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm
Thank you

Can you suggest such laptop with no PWM, or with PWM with very high frequency? It is important for me also.

Good to see that such a list exists. The laptops are all very expensive though, so if Dell could produce a flicker-free laptop that is less pricy this would be much appreciated

Bumped into this tftcentral.co.uk article by accident. It pretty much explains the intermittent flickering I noticed in my XPS 15 9550. DELL support could not figure that out themselves.
The temp solution was then to go to my driver colour settings and decrease the contrast and the brightness.
