| Samsung enhances the clarity of select LCD HDTVs by replacing the light-diffusing plastic face of traditional LCD HDTVs with a natural black panel with a clear anti-glare shield. Reduced reflection of external light creates a new dimension in image clarity, highlighting black and darkened areas, enabling vibrant, more compelling colors and a brighter, clearer picture. Black will never again appear grayish. Black details will show in vivid black even in dark scenes.
The latest version of Samsung’s breakthrough super clear panel technology makes colors appear more vibrant and blacks even deeper than ever. Enhanced films reduce glare and optimize off-angle viewing.

Wide Color Enhancer/Cold Cathode Fluorescent Lamp
The NTSC (National Television Systems Committee) has established the color standards all TVs in America try to meet. And typical LCD TVs only meet about 72% of this standard. Samsung LCD HDTVs use Cold Cathode Fluorescent Lamp back lights to give you 92% coverage of the NTSC standard, ensuring truer, more breathlessly vivid colors.
Samsung’s exclusive Wide Color Enhancer technology delivers more brilliant colors, even in bright areas of the picture where blues and greens are washed out on conventional screens. The system displays wider color reproduction, showing you truer colors – the fresh green of spring foliage, the intense blue of the summer sky. |

Super Patterned Vertical Alignment

TruSurround is a patented SRS technology that solves the problem of playing 5.1 multichannel content over two speakers. TruSurround delivers a compelling, virtual surround sound experience through any two-speaker playback system, including internal television speakers and headphones. It is fully compatible with all multichannel formats up to 5.1 channels. High-quality virtual surround sound can be experienced with just the two hidden, downward-firing side-mounted 2.2-channel dome speakers built into the TV.
SRS TruSurround XT technology delivers an amazing, simulated 3D effect with clear dialog and powerful bass.
TruSurround XT audio also adds three audio enhancement technologies to produce an amazingly immersive sound experience.
- Dialog Clarity brings movie dialog into Focus during the playback of any surround-encoded material to make speech much clearer and crisper.
- TruBass creates incredible deep rich bass allowing a person to perceive significantly deeper, richer low bass tones that are far beyond the physical low frequency capabilities of the speaker itself.
- The SRS WOW feature widens the sound stage by processing standard two-channel stereo material as well as multi-channel encoded material for a dramatic improvement in the playback of any stereo audio over a two-speaker system.
Stereo broadcast reception is offered for MTS and SAP with 181-channel capacity. A sound leveler keeps audio volume consistent during channel picchanging.
Which Size HDTV is Right for My Room?
| With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience. If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get. - Minimum size = Viewing distance/3
- Maximum size=Viewing distance/1.5
