Take command of your multiscreen Mac setup with Screen Commander. Quickly and effortlessly blank your other displays while watching a movie, playing a game, or focusing on some work on a particular screen.

Screen Commander is a simple utility that lives in your menubar and provides screen blanking options at the click of your mouse:

• Blank/unblank the current screen
• Blank/unblank your other screens (while leaving the current one as is)
• Blank/unbank all screens at once

While Screen Commander works with even just one display, it is best suited to a multiscreen setup with two or more displays.

Just darkening, not 'off'

Essentially what this does is draw a screen "black". With some future OLED or similar type desktop display that might actually be good enough to be entirely dark, but with the LCD screens we're all using it still leaves plenty of light bleed, just the nature of the technology. I don't blame the author for this, telling macOS to turn off a video out ala energy saver without doing it to another is likely non-trivial if it's possible at all, and I appreciate the desire behind this to fix what Apple completely screwed up in in 10.9 or so and later (multiple screens worked perfectly with desktops in 10.8). Unfortunately this just isn't a complete solution, at least for now. Still potentially useful during the daytime though, depending on exactly how much bleed through your screens have. And the implementation itself is slick.

Wish I'd found this earlier

I've been wanting something like this for a while, to help focus my work and not distract when watching a movie. You can turn the brightness down manually on your macbook, but that takesa while and only the macbook. This is a quick clik for any monitor. Awesome. Thanks :)

As advertised

Agree with other reviews - download and it worked. Just what I needed blank a screen when I am not using it. I also went 4 stars because with keyboard shorts it isn’t perfect. But still just the ticket if you have this need.
