I was considering a Vizio when I was shopping for my HDTV, but after reading numerous horror stories about the screen turning green or the TV quitting completely after a year, I decided to get a better brand.
Also, they make PC monitors that size that have higher resolutions than most HDTV's. If you're gonna use one as a TV, though, make sure the DVI port can do the HDCP Handshaking protocol. If it can, all you need is a DVI-HDMI cable.
