Video Features

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 1920 x 1080 (1080p).

Video Inputs: The LG Plasma HDTV features HDMI, Component, and Composite video inputs.

• HDMI (ver.1.3): The three HDMI inputs (2 rear/1 side) can be used to connect a DVD player, Blu-ray player, HDTV or 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 support Deep Color and x.v.Color.
• Component Video: The two rear-panel Component Video inputs will accept 1080p (60/24Hz), 1080i, 720p, 480p, and 480i signals.
• Composite: The TV features a rear-panel and side-panel composite video input which will accept a 480i video signal.

Dual XD Engine: The 50PK550 combines two of LG's exclusive XD Engines to maximize picture quality for any type of video content. By combining XD Engine processors, panel performance is optimized ensuring higher color accuracy and more realistic images.

600Hz Max Sub Field Driving: The television's 600Hz refresh rate virtually eliminates motion blur for an incredible viewing experience of fact action sports, movies, and video games.

3,000,000:1 Mega Dynamic Contrast: The Plasma TV delivers a Mega Dynamic Contrast Ratio of 3,000,000:1; which provides stunning colors and deep black, so your picture's details don't get lost in the shadows.

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.

Picture Size (Aspect Ratio): This feature lets you choose the way an analog picture with a 4:3 aspect ratio is displayed on your TV. You can select a different aspect ratio depending on input source (analog broadcasting, digital broadcasting, video input). You can select from:

• 4:3: Choose 4:3 when you want to view a picture with an original 4:3 aspect ratio.
• 16:9: Adjust the picture horizontally, in a linear proportion to fill the entire screen.
• Just Scan: Normally the edges of video signals are cropped 1-2%. Just Scan turns off this cropping and shows the complete video.
• Zoom: Choose Zoom when you want to view the picture without any alteration. However, the top and bottom portions of the picture will be cropped.
• Cinema Zoom: Choose Cinema Zoom when you want to enlarge the picture in correct proportion. This enlarges an image with cinemascope aspect ratio (2.35:1) without distortion.
• Set By Program: Selects the proper picture proportion to match the source's image (16:9 or 4:3).

Picture Wizard (Picture Control): This feature lets you adjust the picture quality of the original image. The LG 50PK550 TV's Picture Wizard (Easy Picture Calibration) offers self-calibration with on-screen reference points for key picture quality elements such as black level, color, tint, sharpness and backlight levels. This features takes the guesswork out of picture adjustments.

ISFccc Mode: This TV contains the detailed calibrations necessary for professional certification by the Imaging Science Foundation. The resulting ISF "day" and "night" modes will then be accessible by the user to experience the best this LG HDTV has to offer.

Please contact your local dealer to inquire about an ISF certified technician.

Image Sticking Minimization (ISM): A frozen still picture displayed on the screen for prolonged periods can result in a ghost image. You can use Orbiter to help prevent image sticking. The other two functions are for removing a ghost image.

• Normal: If image sticking is never a problem, ISM is not necessary - set to Normal.

• Color Wash: The color block with the screen moved a little and the white pattern are alternately displayed. It is difficult to see the after image on all colors. Once it has been corrected it will not be visible in any color.
