installed UT 2 days ago on 1+ Nord N10 (BE2026).
UT talks about 'Desktop Convergence', so I tried to see if my phone could reproduce my Linux Mint LibreOffice 'desktop experience'.
Easy to connect to WIRELESS external display (limited to 1080P), as long as that display runs Miracast (my LG TV's do).
Then I connected Acasis multiport USB-C hub, with PD charging, a wired keyboard, wired mouse, Gigabit ethernet adapter and USB-A Flash drive.
I installed LibreOffice via snap. (direct, no libertine required).
I opened a spreadsheet that had been created on main PC.
not as quick as main PC, but workable.
Image on TV was a bit 'wavy', moving top to bottom, as it refreshed, or something.
A phone model with WIRED external display capability probably fixes the 'wavy'.
I did NOT exhaustively test this.
It was just to see if it would work.
If you have a specific thing to try, let me know. I might be able to give a quick test.
