That's another dilemma: do I go for "authentic" composite video
at broadcast TV rates, or do I use a VGA monitor? If I choose
TV output, the quality's poor and the design only works right for
UK TV systems (625 line, 50Hz, PAL). It would need to be changed
if anyone wanted a US version (525 line, 60Hz, NTSC). But if
I go for VGA, well, that's 15 years old now, I suppose... just
seems too "modern", somehow.
What I'd really like to do is run the display in portrait mode.
