Blackout lets you turn off your displays with just a single click!

I added a large 32" second monitor to my iMac. I want to be able to blank the second monitor when not in use. This app is perfect. Puts an icon at the top status line on the iMac. Click and blank the second monitor. Perfect. Best $1.99 I ever spent. As another reviewer indicated, this just blanks the monitor, it does not remove the monitor from the system. The second monitor still shows in system preferences - exactly what I want. I wouold give this app 10-stars if I could. Perfect for what it does. You want to remove a second monitor, unplug it!

Works well

Would be nice to have options.

- Keyboard shortcuts (individual, all)
- Hide mouse cursor

Super simple

Great for just blacking out displays. Needs shortcuts though.
