Although we are at end cycle of most of these models, I just came cross the March issue of ConsumerReports magazine which they evaluated bunch of LCDs from 55 to 32 inch. And in term of picture quality Vizio along with Sony and Samsung top the chart.

As you can see from the rankings below, Vizio received "Excellent" picture quality rating in every screen size catagory it was in. I'm not a Vizio fan boy, but have to say a job well done.

LCDs are ranked by picture quality in HD and SD mode from EXCELLENT (4 stars), VERY GOOD (3 stars), Good (2 star) to FAIR (1 star) rating. TVs with *asterisk received only 3 stars in SD mode.
