In analog, there is no pixel clocking. So the TV has to guess at what the
number of pixels is, or let the user figure it out through the clock rate
control.

It is plausible to make some guesses. The TV logic could assume the computer
is outputting 4:3 and adjust the pixels accordingly, using the left and right
video edges to find the first and last pixel.

How that would behave on a non-computer video source I cannot say.
