SUMMARY

KDE already has the ability to identify the external screen that is attached (by brand/model) and to apply some setting based on the specific screen (e.g. resolution, magnification, etc.)

Would be great to have the possibility to configure a wall paper for a specific screen.

Rationale: having a different wallpaper on the projector screen to give a presentation (e.g. institutional) than the one you have when you dock the laptop to your monitor (e.g. personal).

I think you may be mistaken; we aren't actually applying settings based on the specific monitor model. And there's a reason for this: we tried to implement that feature in the past, but it just can't work due to how difficult it is to persistently identify specific monitors. You might expect this to be easy, but in the real world it turns out to be practically impossible to do reliably.

Monitors should have something like a Mac address, sad they don't!
