fyi, since many people don't know this exists:
Almost all computer screens made in the last decade support DDC/CI. (The Display Data Channel Command Interface).
You can use it to control stuff like the backlight brightness without fiddling with the awful screen buttons and OSD.
On Linux once you load the ddcci kernel module the screens appear in /sys/class/backlights and can be controlled like a laptop screen.
