Dear supporters,
1. The problem of not being able to adjust the brightness in "multi adapter mode"
Adjusting the pull high resistance of RV466 (499 ohms to 2.2K ohms) can adjust the brightness.
I want to ask why?
2.
When RV466 is 499 ohms,
(1) GPIO7_BL_PWM_GPU -> can be High Low
(2) DGFF_BIA_PWM_1P8 -> keep High
Result:Cannot adjust brightness Fail
3.
When RV466 is 2.2K ohms
(1)GPIO7_BL_PWM_GPU -> can be High Low
(2)DGFF_BIA_PWM_1P8 -> can be High Low
Result:Brightness can be adjusted PASS
