I think it's generally agreed upon that standard definition sets are best for classic gaming. I can officially agree now that I got our old (2 year-old) Sony 27-inch SD CRT TV down from our garage apartment where relatives had been staying and using the set for the past 6 months.
I recently bought a Sony XBR HDTV at about the time I took the 27-inch SDTV up there to the apartment while we had relatives staying with us from Europe. Playing games for systems such as SNES, Genesis, NES (pretty much any system with anything other than a Component/VGA/HDMI connection) on the HDTV was fine and dandy, but there was just something 'off' about the way it looked. Maybe the LCD screen showed too many of the flaws. Also, even with "Game Mode" turned on, which bumps resolultion down to 480i (I think), there was very, very slight lag. Better than most HDTVs, but with twitchy games such as Mario where timing is everything, I still suspected slight lag. Even classic games downloaded on the Virtual Console, though they look brilliant and crisp on the Wii with component cables, seem to play slightly more smoothly control-wise on their native systems connected to a SD television.
What are your opnions. Anyone else have specific classic gaming preferences?
