I’ve just connected my SGS10 to external display.
For now it just mirrors the screen, which is fine for the beginning.
that would be great if it was possible to have a toggle to turn off phone display + horizontal orientation force in such a case.

Maybe…
Developer Options → force desktop mode
sorry for late answer. took me time to update to T13.
I’ve just forced desktop mode.
Importunately didn’t find the option for turning off phone display.
Besides, the desktop mode works better and … battery has option not to be loaded when phone is connecte to usb-c, which is very nice.
