Samsung LN40A550 40" 1080p LCD HDTV

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.

Pictures with high-impact color and contrast
High-definition sources look spectacular on the LN40A550, and standard-definition sources look great too, thanks to Samsung's powerful image processing that enhances contrast, detail, and white balance while reducing noise. Wide Color Enhancer optimizes hues, so colors look rich and vibrant, yet very natural. Samsung also improved their TVs' contrast and black level performance. Dark scenes often look washed-out on LCDs when you turn down the room lights, but not on this model.

A wide array of inputs for versatile viewing
With three HDMI and two component video inputs, it's easy to add multiple high-definition video sources like an HD satellite tuner or video game console. The LN40A550's HDMI connections include "CEC" control capability, which lets you operate other compatible HDMI-equipped Samsung components using only the TV's remote. That's really convenient — especially if you keep your components out of sight in a cabinet or closet. You can also super-size the view from your laptop by plugging it into this set's PC input. And the USB port makes it easy to share digital photos stored on a thumb drive with friends and family.
