I have their 42" Gallevia edition and love it. I use it for pc gaming and HD dvd's. The liquid crystals make a nice pecher.

 

Dell does make some great pc's for certain things.

I'm what you would consider a pretty big Home Theater buff..........so to answer your questions about Vizio..........




A couple hundred dollars more and you are in range of 42" 1080p Toshiba Regza's , or 40" 1080p Sony Bravia's..........which have a significant build-quality difference, picture quality and depth difference, as well as a deeper black level without degrading the color saturation, or the vividness of the picture.

Sony and Toshiba really have picture quality down right now. Samsung's are still wary with me considering they have a VERY grainy picture compared to the Sony and Toshiba screens. Not to mention, they're all mostly glossy-screened..........it the worst thing to have during any kind of daytime viewing........The glare (even in a room without windows) is unbearable.

But I'm VERY picky with my Home Theater products.

 

Here's a screenshot taking from my vizio. Looks good to me.
