x98 plus Guide: PWM screen flickering work around !



Hello,

Another guide from me , actually a tweak to solve the very annoying flickering issue with the screen of the x98 tablet with Intel integrated graphics chipset. You can easily detect this if you point the camera of your phone toward the screen.

The reason of the problem is called PWM which is set to only 200hz in our tablets as default. You can find exhaustive explanation of the issue here: http://www.flatpanelshd.com/focus.ph...&id=1362457985

And the solution is actually very simple: increase the value of PWM to 4000hz (yes much much more than the default value) with this great open source Windows program: https://github.com/tpurtell/PWM

Now our screen will not flicker anymore, I can set the screen light value to 25% and have the same level of colors contrast, without the need of playing with the brightness control of Intel (that would result in a loss of contrast).

Enjoy your new screen!
