I have a RPi5 hooked up to a TV, and I watch movies or TV programs or what
have you by streaming them on the Pi and sending them to the TV via HDMI.
 I assume this is something that most of you have done at some point.
yes with xbmc/kodi

I turn the TV off (really it goes into its low power mode) and leave the
RPi on.
 Occasionally, when I turn the TV on to watch something, there are two
things wrong:
(1) The video no longer matches the TV screen size (1920x1080 in this case).
     The video is slightly larger, in that the edges of the picture are
     off-screen.
sounds like the TV is selecting overscan mode, does its remote have an aspect ratio button, there's usually an option for "exact scan" or "pc mode"

(2) The sound is no longer coming through the HDMI (or, at least, the TV
     remains silent).
 I can get things working again by running the command
         xrandr --size 800x600  ;  sleep 1 ; xrandr --size 1920x1080
(I have no idea why this gets the sound working.)
 Having a work-around is fine, but I'm wondering if anyone else has seen
this issue.  I don't know whether it is
-> a Pi hardware issue
-> a Pi software issue, or
-> a glitch in my TV (Sony Bravia, FWIW).
