DESC: Enjoy a pixel-perfect 1080p picture with the Samsung LN40A550. For most HD broadcasts, and especially for high-def discs, you need a 1080p display like this one to fully appreciate that you-are-there detail and depth. Built-in tuners give you easy access to both digital and analog over-the-air broadcasts (antenna required). And the "QAM" digital cable tuner lets cable TV subscribers watch unscrambled channels without using a separate set-top box.
