[Feature Request] Use screen filter for displays without DDC/CI Support (Or Multiple Monitors) #487

Open tdw46 opened 2 years ago

tdw46 commented 2 years ago

I would like to use brightness slider with several monitors at a time.

To fix this, I recommend creating a pixel filter that overlays all apps, taskbar, start that can dim pixels. A slightly gray/black transparent filter should do the trick.

It seems like this should be a simple/elegant solution, but I'm sure the development behind this approach is more difficult than I assume as a novice.

Thanks for all your effort!

I passed by to open the same feature request; this indeed makes the app 10x more universal and useful! A number of macOS brightness apps allow you to "software dim" an external monitor not supporting DDC/CI, which I really miss in the Windows world.

While I do see the value in this concept, there are several issues that have deterred me from implementing this previously:

While I do see the value in this concept, there are several issues that have deterred me from implementing this previously:

  • Certain apps marked as "always on top" may bypass the filter.
  • Certain apps may lose focus or not detect mouse events correct with the filter active.
  • Exclusive fullscreen apps (such as games) may bypass the filter.
  • Exclusive fullscreen apps my lose focus or minimize with the filter active.
  • Games may incorrectly detect the filter as a cheat, kicking (or banning) users from multiplayer.

Thanks for this reply, is there a reason two monitors that normally work individually for DDC/CI brightness wouldn't work in tandem? I read some other posts that cite problems when using a hub adapter with HDMI. This isn't the case for me, I'm directly plugged into the HDMI and DP connections on my graphics adapter.

Thanks!

You can use f.lux for this purpose, if you do not like the color shifting you can modify the settings and use it as a software dimming filter.
