| The Bottom Line | The HP LC4776N has 1080p resolution and a good selection of inputs, but its middling picture quality and features make it difficult to recommend. | CNET did not review the HP LC4276N, but we did review a larger model in the series. | Deep black levels and accurate color help propel the LED-backlit LG LH90 series into the front row of the LCD picture quality class. | The commendable picture quality of Sony's entry-level 120Hz-equipped LCD makes it a very good value. | The high-end Panasonic TC-PV10 series of plasmas delivers the overall best picture quality of any flat-panel HDTV we've tested so far this year. |
