Part of LG's higher-end Opus series, this 47-inch LCD has a 1920 x 1080 resolution and a 5-millisecond response time. It features TruMotion 120Hz technology to reduce motion blur and produce smoother movement with film sources, and the Super In-Plane Switching (S-IPS) panel is designed to further reduce motion blur and improve viewing angle. The 47LBX's healthy connection panel includes three HDMI, two component video, and one PC input, plus an RF input to access the internal ATSC, NTSC, and ClearQAM tuners. Both the HDMI and component inputs accept 1080p. RS-232 and IR ports allow for integration into an advanced control system. Picture-in-picture functionality is not available. The TV's side panel sports a USB port through which you can view photos and listen to MP3s.

The menu includes six picture modes and three color-temperature options. The Intelligent Eye picture mode automatically adjusts the image based on the room's lighting conditions, and advanced white-balance controls are available. The menu also includes the option to enable and adjust LG's XD processing, with contrast, color, and noise settings. There are five aspect-ratio options, but this TV lacks the ability to view 1080i/1080p sources with no overscan.

Two speakers are subtly incorporated into the 47LBX's bottom panel. Five sound modes are available, including a user mode in which you can adjust treble and bass and choose between 3D EchoSound and SRS TruSurround XT surround modes. A volume leveler is also offered.

Highs:
- The 47LBX's good detail, color, and processing combine to produce attractive HD and SD images.
- This TV's great light output helps HD images pop in a brighter room.
- TruMotion 120Hz technology successfully reduces motion blur, and the S-IPS panel provides a better viewing angle than many LCDs.

Lows:
- The TV's black level isn't as good as the best high-end LCDs we've seen, so the picture lacks some depth and richness in a darkened room.
- Color accuracy is only average.

Conclusion:
The 47LBX is a fully featured 120Hz LCD that offers very good performance. It is especially well suited to a brighter viewing environment, and its good viewing angle gives it more placement flexibility than many LCDs.
