I frequently watch movies on my computer, but I have two screens. So having something displayed on the other monitor is annoying.
I currently use this to turn off my monitors:
xset dpms force off
I was wondering if there's any way to turn off monitors independently, without having to physically press a button on the monitor, of course.
A program that tells the other monitor to display nothing but black would suffice, but I'd really prefer not to waste the power.
I also have Nvidia TwinView, so applications like
grandr aren't aware of both monitors as being independent.
