i'm having troubles viewing my laptop thanks to low frequency pwm. i'm considering to try the pwm utility from github website (https://github.com/tpurtell/PWM), but i have a few doubts.
the creator of the utility warns that Adjusting the value from the default may affect the lifetime of the lamp in your screen. assuming that that's a possible outcome:
1. will it be fixable by replacing the panel?
2. i have some technical questions. can anyone please refer me to a solid laptops hardware forum?
not in high priority, but i have another technical question just in case:
any ideas if this utility can harm the laptop (besides the lifespan of the led)?
according to the creator:
"This is a utility to allow for adjust the PWM driver frequency delivered from Intel Graphics embedded GPU to the embedded LCD panel. It shows you the existing value and lets you pick a new one. 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.
