Basically, I have my PC connected to my TV (secondary monitor), and often watch movies (VLC/Netflix) or play games on the TV in the evening and having my bright-IPS monitor blaring out isn't ideal. I have backlights (Prismatik) installed on my TV which requires both displays to be active (ie I can't just completely turn off my primary monitor) - so, I'm looking for a way to automatically put my primary monitor to sleep or at least dim it whenever a window is active on my secondary monitor, and if not a tray icon that I can activate to sleep/dim my primary monitor - is this possible? Cheers!

That's exactly what I was looking for, no idea how I missed it - thank you!

Great function. Thank you for implementing this

Hi, is there a way to automatically dim other monitors only when focus to a fullscreen game/video instead of "non-currrent monitors" & "non-primary monitors"?

I'm using "non-currrent monitors" with toggle hotkey as temporary solution, but sometime taskbar of other monitor won't dim (attachment), is that a bug?

Hi.
"Fade Everything Except Current Window" doesn't fit my need. Most of the time I don't need Fade function, it cause a flash light when switching between monitors that hurt my eyes.
As mentioned, I just want to fade other monitors while focus to a fullscreen task (fullscreen youtube, fullscreen vlc, fullscreen game), or a special process (someSoftware.exe)
-----
Whenever i click on DF's taskbar (on sub monitor) then focus to main monitor: DF's taskbar won't fade until Start menu is opened. Windows's taskbar (on my main monitor) don't meet this problem

Thank you, hoping that feature will available soon.
