The Bottom Line CNET did not review the Samsung LN40A550, but we did review a larger model in the series. The midlevel Samsung LN46A550 LCD TV strikes an excellent balance between price and performance. 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 commendable picture quality of Sony's entry-level 120Hz-equipped LCD makes it a very good value.
