Vizio 1080p for PC . Any good for movies too?

It's costs $399 and is a joy to look at with a glass screen. I plan to connect a PS3 for gaming/movie's.
As long as your movie playback source can be connected via HDMI, you'll get a signal. How much fine-tuning/tweaking you can do on picture quality is another question.
Looks like it would be very nice for what you want to do. The 3ms refresh time is blazing fast, video games and sports on TV should look terrific. I'd say go for it!
