The Basics:
The D92U Series is one of Sharp’s highest-end LCD lines, and its marquee feature is the use of 120Hz technology, which doubles the TV’s frame rate from 60 to 120Hz in order to reduce the appearance of judder and render smoother motion. The LC-46D92U is a 46-inch, 1080p model with a traditional CCFL backlight, gloss-black frame and slim, detachable speaker bar.

The TV has a solid connection panel that includes three side-facing HDMI inputs, two component video inputs and a DVI input for PC sources, all of which accept 1080p/60 but not 1080p/24. An RS-232 port is on board to integrate the TV into an advanced control system.

There’s a nice assortment of picture controls, including an adjustable backlight that lets you tailor the TV’s light output and black level to your viewing conditions. The OPC feature automatically adjusts image brightness based on your room’s lighting conditions. Aspect ratio options include a Dot by Dot mode for viewing 1080i/1080p images with no overscan.

The Upside:
This TV offers excellent detail, good color and a better overall contrast ratio than many traditional LCDs. It can accommodate a variety of viewing conditions: you can turn up the backlight and get a lot of brightness for a well-lit room or turn it down and get very good black levels for a darkened theater. The 120Hz technology does a nice job of reducing motion blur without making film sources appear overly smooth.
The Downside:
The TV’s viewing angle and de-interlacing/scaling functions are only average and the unit suffers from noticeable screen uniformity issues. The color temperature is somewhat cool and you can’t calibrate the TV.

The LC-46D92U is a very good performer, with a few limitations that keep it from competing with the best flat panels. The 120Hz technology adds a price premium to the LC-46D92U; it does its job subtly but effectively in terms of reducing motion blur, but it doesn’t affect movement as dramatically as other 120Hz technologies, which some people will consider a detriment, others a plus.
