The input panel includes four HDMI, three component video, and one RF input to access the internal ATSC and ClearQAM tuners (there is no dedicated PC input). The HDMI inputs accept 1080p/60 and 1080p/24 signals, and all four are located on the TV's back panel. One of the component video inputs is located on the side panel for easy access, as is a USB port that supports photo and music playback. The back panel includes an Ethernet port to access Mitsubishi's new Web portal, which includes the VUDU HD video-on-demand platform, as well as YouTube, Flickr, Picasa, Pandora, and an "On Demand TV" section. The Ethernet port is accompanied by two USB ports that allow you to add VUDU's wireless accessory bridge.
The setup menu includes a somewhat more thorough assortment of picture controls than you'll find on lower-level Mitsubishi offerings. You get six picture modes, including ISF Day and Night modes that provide access to more advanced calibration options. The general picture menu offers just two color-temperature choices (high and low), but you can adjust white balance more precisely in the ISF modes. Gamma adjustment is absent, but you do get noise reduction and the PerfectColor/PerfectTint system to adjust the hue and saturation of the six main color points. Mitsubishi's Variable Smooth240 technology addresses both motion blur and film judder; the LT-46249's setup menu differs from some lower-level Mitsubishi TVs: instead of high, standard, and off settings, you can perform incremental adjustment to produce the desired level of smoothness in film motion. The TV offers six aspect-ratio options for SD content and three options for HD content, including a full native mode to view 1080i/1080p signals with no overscan.
The integrated sound projector is attached to the TV's bottom panel and receives its audio signals directly via the TV's input panel. Audio signals can be input via the HDMI inputs, the RF/antenna connection, or a coaxial digital audio input. The LT-46249's back panel includes a subwoofer output to direct the low frequencies to an outboard subwoofer. The 18-speaker ISP is designed to present the complete multichannel soundfield, creating a sense of surround envelopment by bouncing sound waves off of room boundaries. The sound projector's setup menu includes manual and automatic setup options, and a microphone is supplied to perform the auto setup. The TV has internal Dolby Digital 5.1 and Pro Logic decoders to handle soundtracks from your DVD player or set-top box. Other audio setup options include four preset sound modes (stereo, surround, music and night), as well as bass, treble, and balance controls and a level sound feature to minimize volume discrepancies.
Finally, the back panel features an RS-232 port to integrate the TV into an advanced control system, as well as an IR jack that can serve as either an input for an external control system or an output, if you set up the TV's NetCommand system to control other devices.Read about the high points and the low points of the LT-46249 on Page 2.
