How to change Steam link aspect ratio to 4:3 or mobile screan resolution?

[CheG]

1 As steam link doesn't run all over the phone screen (Fold4) I still see a blurry wallpaper underneath and before playing I have to change the wallpaper to a black screen so it doesn't interfere with the game which is annoying, is it possible to change this somehow?

2. is it possible to change the resolution and aspect ratio of the screen in the steam link app? Because as I have an aspect ratio of 16:9 on my laptop Steam link persistently pushes me such an aspect ratio, and when playing on Fold 4 I would like a different screen ratio preferably 5:4 but can also be 4:3, do you have a solution for this?

probably the most direct approach.
Steam settings -> Remote Play -> Advanced Host Options -> check "Change Desktop resolution to match..."
on client change alter the resolution to fit your needs.

Also make sure the desired resolution is in your display driver, and if not add it as a custom resolution.
