And plenty of places won't have just one TV being watched too.

Then you'll have two channels to pick out of the total household
consumption - no different to a radio receiver picking out one signal
from hundreds of others.

Very different to a radio receiver because there is no turning mechanism.

The tuning(sic) mechanism is digital signal processing, which produces
the same effect as analogue signal processing with inductor/capacitor
circuits/PLLs etc.

FWIW I've got an old 19-inch Dell "Ultrasharp" monitor in the other
room that's a little furnace.

None of my monitors are.

Because their overall power consumption is lower, not because the
percentage used for the backlight is less.
