This should fix the FN+F9/FN+F10 screen brightness or screen dimming not working issue. Drivers: Working Driver (As of 3/4/23):www.nvidia.com... Dell Driver(did not work): www.dell.com/s...
I've sent my laptop into Dell twice for this same issue. Its been less than a year and I'm having the same dimming issue once again. I was hoping this video fix would do the trick but no luck.
