We still have our old TV, and we aren’t sure we are gonna replace it when it goes.
However, my mother has a flat panel (not hooked up to anything) and when she heads out to CA for the winter, it comes over here.
I used a VCR(tuner) into a composite-2-VGA converter into a used 23” CRT monitor as a TV for quite a few years until 1080P flat panels dropped into my price range.
