The same thing I had years ago. When
VGA became common, in electronic catalogs you could pick up 13 inch CGA monitors for cheap. Myself and just about everyone at the TV stations bought a couple.
One of the most common uses was hooked to the output of a VCR on composite video (you had to buy a CGA with composite input and sound).
So with a VCR and CGA monitor, one had a TV that could record and play back.
Substitute today's
CECB and viola, same thing, new day....
