| The Bottom Line | The 46-inch Vizio GV46L HDTV costs less than the big-screen LCD competition, but its picture quality isn't up to par with the company's other bargain efforts. | The Vizio SV470XVT represents a viable alternative for LCD TV bargain hunters who want 120Hz processing. | Sure, it has a few flaws, but nothing fatal prevents the local dimming, LED-backlit Vizio VF551XVT from exhibiting excellent LCD picture quality for the buck. | It costs a mint, but Samsung's local dimming, LED-based UNB8500 series delivers the best picture quality of any LCD we've tested. | Although its image quality still can't compete with the plasma competition, the 1080p Vizio GV47LF HDTV is a fine bargain for folks who want an LCD TV. |
