VIZIO introduced more new flat panel displays at CES than any poor scribe should have to deal with. So I'll mention only the largest sets in both the plasma and LCD premier lines. The 1920x1080p VP504F is a 50" plasma ($1699) with Silicon Optix REON video processing. As of now the VP504F is the only set in the new VIZIO line, either LCD or plasma, that uses the REON, though more are possible before the new lines start showing up in stores in May and June. A contrast ratio of 30,000:1 is claimed.
