178 degree viewing angle

With a super-wide 178 degree viewing angle, you and all of your guests will always be able to enjoy the movie no matter where anyone is sitting in the room.

CCFL - Cold Cathode Fluorescent Lamp

Enjoy brighter, more true-to-life pictures and vivid colors that will simply amaze you. SAMSUNG LCD HDTVs give you 92% coverage of the National Television System Committee's standard as compared to the 72% that competitors offer. That translates to brilliant images that really enhance your entertainment experience.

5 ms response time

One of the most important features for an LCD panel is the pixel response time. Response time refers to how long it takes pixels to turn from completely white to black and back again - the lower the milliseconds (ms), the faster the response time is. A fast 5 ms response time virtually eliminates any blurring and gives you smooth-motion action scenes.

ENERGY STAR compliant

By being ENERGY STAR compliant you are assured that your SAMSUNG model is helping the environment by using less energy while saving you money. ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy promoting energy efficiency.

Wide Color Enhancer

Experience more brilliant colors - even when blue and green shaded areas of the picture are washed out on conventional screens. Simply imagine a wider range of colors than you ever thought possible.

30,000:1 contrast ratio

Contrast and brightness levels achieve new heights in this LCD TV. Get a more realistic, sharper picture quality that's sure to catch your eye and watch movies and shows come to life.

Hidden Bottom Speakers

Less is more. Just because you can't see the stylishly concealed speakers doesn't mean you won't hear the unbelievably clear sound radiating from them.
