And another part of the difficulty with discussing this is that most of 
the newer LCD and plasma displays are not like TV's at all.
If there is an HDMI input, then it will likely work from a VGA output

bets are off...And my TV was built in 1982...I need something with a 
balun transformer on the end!!
