scalling under kde wayland


i use kde with wayland
i have a 4k screen to the left of my laptop lenovo t450 (1600x900)

scaling in the kde center is only 1 or 2

is there a way to get 1.25 (fractional scalling)?
would like to do it only for my 4k screen.


My 2 cents: KDE on Wayland is just not ready yet. Are you able to get what you want to achieve on KDE on X11 ?

not really because on x11 you can put scalling different on every screen
