Sharp's Slim-line D64U Series is so named because the cabinet has 25 percent less depth and 20 percent less weight than previous Sharp LCDs, and there's only about 1.5 inches of bezel surrounding the 46-inch screen. This 1080p LCD has a 4-millisecond response time and a healthy connection panel that includes three HDMI, two component video, and one PC input, plus a single RF input for access to the internal ATSC, NTSC, and Clear-QAM tuners. Both the HDMI and component video inputs accept 1080p/60 but not 1080p/24, and Sharp has put one HDMI and component video input on the side panel for easy access. Picture-in-picture is not available, but an RS-232 port is included, so you can integrate the TV into an advanced control system. This TV does not include the 120Hz technology found in Sharp's higher-end LCD lines.

In addition to a whopping eight picture modes and five color-temperature settings, the LC-46D64U features a Color Management System that lets you precisely adjust the hue and saturation of the six color points. The OPC feature automatically adjusts image brightness based on your room's lighting conditions. However, advanced white-balance and gamma controls are not available. The TV features four aspect-ratio options for both HD and SD sources, including a Dot by Dot mode for viewing 1080i/1080p images with no overscan.

A thin, silver speaker bar runs along the bottom of the panel. The audio menu includes treble, bass, and balance controls, as well as a generic surround mode and bass enhancer and the option to turn off the screen and only output an audio signal.

High Points
• The LC-46D64U produces a wonderfully detailed 1080p image, and colors look natural.
• Its great light output makes it well suited for a brighter viewing environment.
• The Slim-line form successfully draws your eyes to the screen and helps you fit a larger screen in a smaller space.

Low Points
• The LC-46D64U's color temperature is somewhat uneven, and the TV can't be calibrated.
• The black level is good but not exceptional, so the image doesn't look quite as rich in a dark room.
• The viewing angle is average, and the screen suffers from uniformity issues.

Conclusion
The LC-46D64U is a solid everyday performer that is especially well suited for a brighter, daytime viewing environment. High-definition images look great, and the TV has a well-rounded connection panel.
