K4sum1 Posted May 22 Share Posted May 22 I got a M4800 with a Quadro M2200, it's pretty nice but I can't seem to control the brightness from within Windows. If I use the hotkey I get the UI element of the brightness change but it remains at its current brightness. The power options slider doesn't work either. Doesn't matter if plugged in or not. Only the BIOS brightness slider appears to change anything for Windows. Oddly Linux Mint 21 runs at a very low brightness, and I can adjust it, but only down, down enough where the backlight just turns off.
