About the Samsung LN37A450

Whether you're looking for a new living room HDTV or a second set for another room in your home, consider the Samsung LN37A450. Its 37-inch screen size is big enough for a modest home theater system, while its slender cabinet allows it to fit easily in many bedrooms and home offices.

Whether you're looking for a new living room HDTV or a second set for another room in your home, consider the Samsung LN37A450. Its 37-inch screen size is big enough for a modest home theater system, while its slender cabinet allows it to fit easily in many bedrooms and home offices.

This versatile HDTV has built-in tuners for both digital and analog over-the-air broadcasts (antenna required). These tuners ensure that you'll continue to get a clean, vibrant picture during the current transition period and after the switchover to digital is completed in 2009. And if you're a cable TV subscriber, you can take advantage of the LN37A450's built-in "QAM" digital cable tuner to watch unscrambled channels without using a separate set-top box. HDTV programs look amazing, and non-HD channels look surprisingly good as well, thanks to Samsung's advanced video processing.

The LN37A450 gives you a wealth of inputs for connecting both high-definition and standard-definition sources, including three HDMI inputs for hooking up compatible components such as satellite receivers and video game consoles. A standard PC input lets this set pull double duty as a computer monitor.
