The connection panel includes four HDMI inputs but only one component video input--a trend we're seeing with many new higher-end TVs. It also has a PC input and an RF input to access the internal ATSC and Clear-QAM tuners. The HDMI inputs accept both 1080p/60 and 1080p/24 signals, one supports the Audio Return Channel function of the HDMI 1.4 spec, and all four are side-facing for easy access. Two USB ports are available for music and photo playback. As I mentioned, an Ethernet port is available for network connectivity, and there's also an RS-232 port to integrate the TV into an advanced control system.
The LC-46LE820UN has a solid array of picture adjustments, but you don't get quite as many advanced options as you'll find in other higher-end TVs. Among the choices are: nine preset AV Modes; an adjustable backlight and an OPC function that automatically adjusts the picture's brightness based on your room's lighting conditions; five preset color-temperature options plus global RGB controls to fine-tune white balance; advanced color management that lets you adjust the hue, saturation, and value of the six main color points; gamma adjustment; and digital noise reduction. The Fine Motion Enhanced 120Hz menu includes off, low and high options. The LC-46LE820UN has four aspect-ratio options for SD content and five options for HD, including a Dot by Dot mode for viewing 1080i/1080p images with no overscan.
The audio setup menu includes bass, treble, and balance controls, plus auto volume, surround, bass enhancer and clear voice options. The LC-46LE820UN does not offer advanced volume-leveling technology from a company like Dolby or SRS.
Finally, the Power Control menu includes power-saving settings to reduce power consumption, as well as an Audio Only option lets you turn off the video signal when you're only listening to an audio source (like a digital music channel or MP3s through the USB port). There are also settings to automatically turn off the TV when no signal or no operation is present for a designated time period.
