What about those new LCD or Plasma-TVs with VGA or DVI-in ? Do they 
really act like a computer monitor (hi-res, progressive), or do they 
interlace the input to fit PAL standard before feeding it to the panel ?
What I'm personally doing is getting more-or-less acceptable output from 
the TV-out port of the VGA card (far better than analog TV, btw), just 
as a transition before I get a brand new plasma TV when prices have 
dropped enough... Then I will totally forget all those interlacing 
problems...
Hum, will I ?
