Or people who turn the brightness up on their monitor to "make the sun look dim in comparison".

My TV has its backlight set to '0' (OLED, and a non-real property to set as no 'backlight', but still a metric). If I set it to 100 my eyes bleed. My current monitor with a real backlight has it set to 5. Yes, 5 out of 100.

I think grey on grey works, if the very walls behind you are being bleached by the intensity of the light coming off the monitor.

And those monitors aren't any monitors, they're glossy expensive Apple monitors.
