| The Bottom Line | CNET did not review the Samsung LN-T5781F, but we did review a smaller model in the series. | A breakthrough in LCD picture quality with some issues, the LED-powered Samsung LN-T4681F will nonetheless impress the staunchest videophiles. | It costs a mint, but Samsung's local dimming, LED-based UNB8500 series delivers the best picture quality of any LCD we've tested. | 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. | Deep black levels and accurate color help propel the LED-backlit LG LH90 series into the front row of the LCD picture quality class. |
