I agree 100% with what Bingo13 said.  I just bought a Samsung 170T LCD, and it uses all the latest LCD technology.  So far I have noticed zero ghosting, and very limited motion artifacts playing Tribes 2, Black and White lately.  Even when I use the scaling feature to fill the screen in non-native resolutions, I noticed a slight picture quality difference, but it was far from unuseable, or horrible looking.  Currently I'm using the analog connection, can't wait for my replacement cable to arrive from Samsung so I can try out the DVI connection.
