The overscan settings are described here:

I also put these into my 'config.txt':
I am now getting 1080p, that is, 1920x1080 pixels, on my TV screen. It is a 20 inch TV.

Ah, no, at bootup, my TV reports that input is 1080i.

Anyway, my old eyes prefer everything to be bigger, so I have added this:

Note, I did try "hdmi_mode=4" which is 720p 60Hz, but got a blank screen.
Ah yes, very easy on the eyes.
