I just noticed that this went as a direct reply.  Resending, FWIW, to list.

A lot of work was done in master around the 2020 New Year that affected
this sort of thing, and I don't know if that has reached v30.  But 
frontend setup has settings for framed/unframed windows and for
identical or separate UI/Video geometries that you might need to adjust.

I used framed 'frontend setup' windows on a monitor, and a -nw 
--geometry override to put the display onto the TV; but I haven't 
returned to using HDMI with TV since something bricked my TV#1...
