The LT-42P789 is part of JVC's TeleDock line of LCDs, which includes four models (32, 42, 47, and 52 inches) that feature an integrated iPod dock. Through the TeleDock, which is discreetly nestled between the two speakers that run along the TV's bottom panel, you can watch videos, view photos, and listen to music - including all copy-protected content purchased through the iTunes Store - and control playback using the JVC remote. The 42-inch LT-42P789 has a 1080p resolution, uses a traditional fluorescent backlight (as opposed to LED backlighting), and does not offer a 120Hz frame rate to reduce motion blur or judder in film-based sources.

The back panel includes three HDMI inputs, two component video inputs, and one RF input to access the internal NTSC, ATSC, and Clear-QAM tuners. The HDMI inputs accept a 1080p/60 signal, but not a 1080p/24 signal. There is no PC input, nor does JVC locate any HD-capable inputs on the side or front panel for easy access. The side panel does sport a USB port through which you can view JPEG photos. The TV lacks picture-in-picture functionality.
The LT-42P789's setup menu includes the basic picture controls that we would expect to find in an LCD, including an adjustable backlight, noise reduction, four preset picture modes (standard, dynamic, game, and theater), and three color-temperature choices (cool, natural, and warm). However, it lacks many of the advanced options found in higher-end models, such as white-balance controls and precise gamma and color-management controls. Likewise, the audio setup options are solid but not extensive. You can choose from four preset audio modes (speech, jazz, classic, and rock) or tailor the sound quality using a five-band equalizer. There's also a generic surround mode, with options for movie, music, news, and mono. This TV features a solid assortment of aspect-ratio choices; there are four aspect ratios for SD sources and five for HD sources, including a full native mode that lets you watch 1080i and 1080p sources with no overscan.
The TeleDock onscreen navigation interface provides only general playback and shuffle options for music and video; its menu structure does not mimic that of the iPod itself, and you can't search for specific songs, artists, playlists, or videos. If you'd prefer to navigate content directly via the iPod, JVC does provide an option to do so; this direct method offers more complete access to your song and video libraries and allows you to view photo slideshows, but you have to physically walk over to the TV to navigate the menus.
