| The Bottom Line | CNET did not review the Samsung LN40A650, but we did review a larger model in the series. | If you don't mind its red frame, the Samsung LN52A650 LCD TV will reward you with a massive feature set and excellent picture quality. | While not up to the picture quality of Samsung's topflight models, the feature-rich, uniquely styled LNB650 series still outperforms most LCDs on the market. | The Samsung LNB750 series can't beat the picture quality of the best plasmas and LED-based LCDs, but for a conventional LCD, it's one of the best we've tested. | It costs a mint, but Samsung's local dimming, LED-based UNB8500 series delivers the best picture quality of any LCD we've tested. |
