Before opening the issue, have you...?

Searched for existing issues
Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

I disabled "smooth transitions" and the transition still takes multiple seconds on my external display.

Note that I indeed see a change in transitions when touching brightness of the internal monitor (the smooth one being waaay faster on the internal monitor than on the external one).

Steps to reproduce

Configure the app as in this screenshot:

Opening the app
Clicking on the transition bar on the other side of the current brightness on the external monitor

Expected behavior

Should jump to the selected brightness

Anything else?

No response

I am not sure how this looks visually. Some displays do have their own smoothing algorithm for DDC control - this setting will not affect that.
