Does not work in Yosemite.

I tried this with my two external monitors on iMac 5k. It did disable the monitor but came back right in couple of seconds.

Which one did you disabled Internal or External?

I'm experiencing the same issue when disabling the internal (iMac display), running v1.92 on OS X 10.10.3. Just tested disabling the external display, same results. Also, interestingly, after trying to disable the displays, re-enabling and repeating, the displays seem to be flipped (left display not positioned to the right). Trying to disable display 1 again will result in display 2 being disabled... weird. I also tried old releases of disableMonitor to no avail (1.8, 1.9).

Same issue, same setup.

iMac 5k w/ external thunderbolt monitor on 1.92

Selecting "disable" for external thunderbolt display hides windows, blacks out display, and then display turns back on 1-2 seconds later.

I'm running 10.10.4 and as you might have noticed, one wallpaper is overlapping the other.

Apart from that, I must say its working fine. It would help it that little thing could be fixed.

Also, in helping to debug the issue. Here is the screenshot of Expose (or Mission Control as its called now), which shows the desktop overlaying effect and disregarding OS X commands.

This happened almost everyday. Also sometimes when I disable the mac monitor it blocks the screen to type the password.

I found two more issues.

1. When you turn off integrated display (Color LCD), the brightness setting on the display remains the same. So, there is no image on the screen, but you can notice the backlight powering the display.

2. If for some reason your keyboard backlight remained active, when you press F5 to turn the light all the way down, the notification icon (semi transparent rounded square with dashes) is shown outside the viewing area, somewhere between the 1st and 2nd display. Image attached.

I love this app, but these three issues: the background, the display brightness and keyboard backlight notification. Once they are fixed, this app is golden.

Not sure if this helps anyone or not, but this was happening to me when I first started using this app (the screen turning back on after a few seconds) and I resolved it by first mirroring the displays, then disabling the desired monitor.

[ChrisMayhew]

That's a good idea afrat but for me it defeats the object of the app, I am was using the app to make it easy to disable the monitor to use on another computer. But like i said it's a good idea.

@ChrisMayhew ah, I see. I'm using this app to disable my Macbook display and just my external.

I'm unable to turn off the internal monitor while the laptop is running on battery. Also noticed the same brightness setting issue as sirNemanjapro.

v1.92 running on OSX 10.10.4.

Shutting off the screen works fine but I'm also running into the duplicate wallpaper problem mentioned above. I'm using a MacBook Pro (Retina, 15-inch, Mid 2014) on 10.10.5 and a DELL P2715Q Display.

Possible overlapping wallpaper fix; Disable the "Displays have separate Spaces" option in Mission Control settings. This resolved the problem for me but you'll need to reboot for it to take effect.
