Monitor / TV Issues (Backround Switched)

Hey there
My Situation is as follows,
My Computer is in my Living Room next to my TV i got my Samsung G9 in duel screen mode (DP1 21:9, DP2 4:3) and my TV HDMI 1 (16:9).
For Steam Big Picture (couch Mode) the Tv Has to be Primary but wehn i am at my desk (Work Mode) i want DP1 to be primary.
Issue:
Wehn Primary (TV) is turned off for work mode, the backrounds are changed because now DP1 is Primary and for some Reason the backround allocation is based on the Screen Priority and not the screen name or Port Connected and since the Screen Sizes and Ratios are all Different none of the Backrounds match anymore.
Question
Is there a way to make backround settings tied to the monitor name or Port like DP1?

or maybe a way to force big picture to open on the tv if its on and force any newly open app(games) to open there too but if the tv is not on, open them on dp1

Hi! Am I understanding the question correctly, that you’re wondering if it’s possible to have the background wallpaper not be connected to a display priority, but to a physical device?

If so, that connection is intentional, as the wallpaper follows along with other aspects of the “primary” display, including icons, panels and widgets: 482347 – Switching primary screen swaps wallpaper

If not, I apologize - a screenshot or picture of the situation and what you’re looking to change about it might help :slight_smile:

yeah you understood me correctly and i was afraid of that, do you have a workaround idea for my setup maybe? i dont want to have to build a seperate mini pc just for my tv thats littarely right next to my pc and kvm dont work either because the resolution changes and the screen ratios…

waht i would love is a option to make my monitor primary but wehn my tv is on all applications that i start open up on the tv instead of the primary
