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.

Does anyone have any ideas about this? – Neil Nov 16 '10 at 1:53

I use grandr for monitor management.

apt-get install grandr

It has a handy GUI, which you can start from terminal and offers the functionality you need.

I'm use Nvidia TwinView and the proprietary nvidia driver, so grandr only sees one screen that's two screens big. It won't work. – Neil Feb 15 '10 at 5:53
