Backlight on disabled internal monitor
My configuration
- Yosemite 10.10.5
- DisableMonitor 1.92
- MacBook Pro (13-inch, Mid 2012)
- Graphics: Intel HD Graphics 4000 1024 MB
When I switch the internal monitor off, I can see the backlight on, like it all the screen was turned to black but not disable. My expectation was that disabling the monitor would turn it off completely.
This application is really what I was looking for, I was using the "fridge magnet" solution but I am a little bit scared about magnets on top of my laptop.
I can confirm, that display stays on, only fill of black color :).
El Capitan 10.11.1
Happened to me to, I even managed to put my mouse on the black screen and couldn't move it back to the enabled monitor... o.O It was weird.
Tried a few times, It happens when using the hot corners to pop up mission control. El Capitan 10.11 here.
Not sure this helps but confirming iMac built-in display backlight is staying on for me too. Was expecting for it to turn off completely, but honestly still unsure if the intended behavior is to dim w/ backlight still on or what I was originally expecting. The description does not make that clear. I'm assuming by this issue thread that it is supposed to disable it completely (turn off). Here are my details:
- El Capitan 10.11.3
- DisableMonitor 1.92
- iMac 10,1 (Late 2009, 21.5")
- Graphics: NVIDIA GeForce 9400 256MB
- My use case: iMac is off, connect external monitor by mini display port, turn on iMac, mirror main display to external, disable iMac screen with DisableMonitor.
Just wanted to also say THANK YOU VERY MUCH for DisableMonitor. Even in it's current functionality for my computer (monitor dark but with backlight on), it still is doing what I wanted it to do. Turning it off completely would be fantastic. I will try and donate something to you when I can. Regardless, your efforts are very much appreciated, especially for something such as the iMac where AFAIK Apple still refuses to allow the iMac screen to be turned off. I'm sure they have their valid reasons in addition to marketing/sales reasons, but there are also very many reasons for people to want to turn off their built-in screens. My personal one is that there is a manufacturing defect affecting the screen and using an external monitor is my current solution.
got the same here as well with new macbook pro 15 touchbar + usb-c lg 5k monitor
Same for me. I'm on Mac OS Sierra on a MBPr 2017 15" with touch bar + 2 Thunderbolt display. The disabled monitor isn't off completely. It has backlight.
