Graphics, sound and multimedia • Using non-integer scale setting for Screen

Hi all,

My first post here. Please correct if this is the wrong place to ask.

I have bought a 500+ Kit recently. Very nice! It came with Bookworm pre-installed on the SSD so my first activity was to install Trixie on it. That went smooth using Network install.

I am using a 32" 4K monitor as my display. The Pi uses the 4K resolution of this display as default. In the Control Centre you can change the display settings via Screens.

I would like to select 4K resolution with a Scaling of 1.5x. I see 1.0x, 1.5x, 2.0x and 3.0x. If I choose 2.0x it works, but I get too big text and too little screen estate. Therefor I would like to select 1.5x. However 1.5x is greyed out (cannot be selected).

I've found some posts that explain how to specify display settings via the terminal in ~/.config/kanshi/config
When I change the "scale 2.000000" to "scale 1.500000" and reboot, the screen remains black (no GUI).

Are non-integer scaling factors not supported yet?
If they are, how can I obtain a 1.5x scale with my 32" 4K monitor?
