Now that monitors are all fancy and digital, display manufacturers lost sight of the utility of the brightness knob. Of course I can go fiddle with the now-cumbersome digital brightness settings buried somewhere in the menus of each monitor, after I curse at my monitor because I hit the auto calibrate button by accident. Then onto the right-hand-side monitor. You get the idea.
Anyhow, is there any equivalent on a desktop PC to the proprietary key combinations laptop manufacturers use to quickly and easily adjust display brightness?
