HDTV Tuner: The TV has built-in over-the-air HDTV (ATSC) and
Digital Cable (QAM) tuners, so you don't need a separate set-top box to receive
and decode over-the-air HDTV/SDTV or unencrypted Digital Cable signals.
1080p Resolution: The LG 50PK550 Plasma TV has a display
resolution of 1920 x 1080. All of the television's video inputs are displayed at

Satellite Set-top box with an HDMI output. The HDMI 1 input can also be used
to connect a device with a DVI output (a DVI-to-HDMI adapter cable is
necessary). If a DVI-equipped device is used, a separate audio cable will
also be needed from the device to the "PC/DVI Audio In" 3.5mm stereo audio
jack. No audio cables are needed for an HDMI-equipped device. The HDMI jacks
will accept 1080p (60/24Hz),1080i, 720p, and 480p video signals; as well as

Intelligent Sensor: The LG Plasma TV's
Intelligent Sensor automatically optimizes the picture to the lighting
and color conditions in the room for a more enjoyable viewing experience. Unlike
other sensors which can only sense brightness of
ambient light, LG's "Intelligent Sensor" uses 4,096 sensing steps to
evaluate its surroundings. Using a sophisticated algorithm, the LG processes
picture quality elements including brightness, contrast, color, sharpness and
white balance. The result is a picture optimized for it's surroundings, more
pleasing to watch and which can also save up to 50% in power consumption.
