Can someone explain the differences between monitors designed for use as
computer displays and those intended for ordinary video?  I would like to
find a color monitor that accepts both separate RGB inputs (such as from
a computer) and conventional (NTSC composite) video.  Do computer monitors
generally require greater resolution?  Is one monitor suitable for both?

A related question: does a standard exist for RGB video signals?  Although
several "IBM PC compatible" monitors are now available, I seem to recall
hearing that normal (analog?) monitors wouldn't accept the (digital?)
signal from the PC.  Are TTL levels used at the 8-pin interface?  There
seems to be a lot of misinformation regarding compatibility.  What's the
real story?
	Thanks
