RDP Resolution issues with desktop scaling

I can not figure out how to proper set resolution

My Windows Desktop is set to 200% with a resolution of 3840 * 2160 (UHD)

Somehow RDP connections are affected by that 200% in EMBEDDED mode
they get scaled down - to 1920x1080

if i change windows desktop scaling to 150% Session resolution changes to some higher res. and when i select 100% it has almost full UHD

so, of course i do not want use 100% windows desktop size because its insane small
but neiter do i want to have 1920x1080 RDP size
and if i use 150% its kinda blurry

tldr; i have insane high windows desktop resolution, i want to connect to other computers with RDP, when i select fullscreen, it shall be almost UHD, if i select 1920x1080 it should be in a window within the workspace (or maybe zoomed) but not some random resolution scaled to somehow fit the workarea
