Greetings,
I've just installed on a Pi4.
The Pi correctly identifies the monitor as 4k:
kali@kali:~$ /opt/vc/bin/tvservice -s
state 0xa [HDMI CEA (95) RGB lim 16:9], 3840x2160 @ 30.00Hz, progressive
However, the desktop appears in 1080p and doesn't offer any other resolutions.
Any hints on where to look to get the desktop in 4k?
Thanks!
