    hi,
    i want to try the github project designed to increase the displays' PWM frequency.
    https://github.com/tpurtell/PWM
    i'm using my own SSD hard drive for this. afterwards i'll replace it back to the original hard drive. can anyone say if this kind of software leaves any "evidence" in the bios event log etc'?

    Description of the utility:
    " This is a utility to allow for adjust the PWM driver frequency delivered from Intel Graphics embedded GPU to the embedded LCD panel.
    I think the value it reads back and writes is the frequency in Hz. The actual output was not checked via high speed camera or anything like that, but it seems to have the same behavior as sending those intel_reg_write commands from linux with the computed values. The driver actually has two configuration DWORDs, the default for me for these two values in decimal is 2 and 200. This utility just keeps the first value as read back from the driver and changes only the second value. It's possible the first value is duty cycle or mode related, or something completely different. "


    thanks
