They didn't used to be. OMG the Component video quality when the 360 launched! BLEH!
I wouldn't know now. I leveled up and moved onto Plasma when Panasonic bought Pioneer's "Kuro" tech on the cheap and started doing sets that previously cost £2500+ for £600 :D
If I never had to look at an LCD screen again I'd be happy. But sadly my laptop has one and my screens at work are also LCD :( disgusting tech that should have been left behind last decade were it not for the race to the bottom for cheap big displays :/
