Our take on the LG 50PK550

If you thought plasma wasn't for you, the 50PK550 should make you reconsider. Plasma TVs are known for their remarkably realistic, vibrant picture quality, and this LG is no exception. You'll love its deep, dark black levels and punchy, true-to-life colors. It's plasma, so you can count on blur-free video motion, along with impressive picture depth and dimensionality. And with it's ultra-slim, gloss-black bezel, this TV looks beautiful off as well as on.

Get the best picture, without the guesswork
LG knows that when you take your TV out of the box, it's not necessarily set up to look its best in your room. That's why the 50PK550 has a simple screen calibration system built in. It helps you dial in key settings like black level, color, and sharpness, so the picture's optimized for your room and tastes. And since the TV can automatically adjust the brightness of the picture to best match the light levels in your room, the picture will look consistently vivid and detailed.

My 2-cents

Todd from Florida on 3/2/2011

Crutchfield Customer Review (What's this?)

So far so good. Have owned the set since 2-15-2011and it is impressive for the relative small amount paid.Colors seem very accurate with out being over saturated and the reflection is not as bad as I thought by reading other reviews. I have not even tried to dig deep into the picture settings yet waiting for the 100 hour break in period. My one complaint is the ir remote, you have to practically aim it at the ir port on the TV to get it to respond,guess that's what a good universal remote is for . p.s looks like the set is discontinued at crutchfield people will have to step-up to the 60in.

DavidT from Apex, NC on 2/3/2011

Crutchfield Customer Review (What's this?)

This was my first experience with a flat screen. After much research I decided on this plasma from LG. I have been extremely impressed so far. The picture quality is excellent. I tried using the energy saver mode, but found that the screen just wasn't bright enough. As soon as I turned that off, the picture is amazing. Burn-in has not been an issue at all so far, but I've tried to be very careful not to leave the same image on the screen longer than a few minutes. The screen is kind of reflective, but it's really not that noticeable when you are watching a show. Haven't used the TV speakers at all because I have the sound going through my AVR, so I can't speak to that. Overall, this is an excellent TV at a great value. Highly recommended.

ChefJim from Elgin, IL on 1/28/2011

Crutchfield Customer Review (What's this?)

Awesome picture quality and easy to operate; plenty of HDMI and other connection points made it an easy install. We were concerned about the comments on plasma screens losing clarity in bright rooms being an issue but we have not noticed any big reduction in screen quality in bright light; we have patio door blinds and just closing them slightly to redirect the sunlight brings the picture quality back to 100%. The first set arrived in pieces due to shipping and Crutchfield was quick to replace it. Needed some technical support during the install to get our stereo system to integrate and that was a 3 minute phone call to get the info we needed. This set is a definite best buy in our book and the Crutchfield team did not disappoint us!




Rob M. from winchendon mass. on 1/9/2011

Crutchfield Customer Review (What's this?)

This TV is awsome. Very easy set up. The controls are easy to navigate. I was choosing between the Samsung,Sony or the LG. We found the LG had the best light, not to brite, not to dark. We have it in a room with little natural light. The picture is great. The kids think it's the best. Also upgraded to HD. WOW. Cruchfield was a great place to buy. Rhonda was very helpful. The articals on the web site are very good. I had my TV in a few days.They also helped decide on a new receiver to replace my 20 year old sony. Thanks Cruchfield for a positive buying experiance.



This is the best value in TV's

Monty D from Highlands Ranch, CO on 12/16/2010

Crutchfield Customer Review (What's this?)

Years ago Plasma TV's got a bad rap because of altitude issues, heavy and uses lots of electricity. All of that has gone out the window. This is a great value TV with it being energy efficient, light weight and an incredible picture quality. I have a 55" Samsung LED TV also and this LG 50" offers just as good of a picture. Check out the hour life of this TV, it's much higher than any other TV on the Market.

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.

Note: The television's HDMI inputs do not accept 480i video signals.

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.

Picture Modes (Presets): There are factory presets for picture settings available in the user menu. You can use these preset modes or change each picture setting manually.

  • Standard: This mode provides optimum viewing for general use.
  • Vivid: Maximizes the effect of the video by strengthening the contrast, brightness, color, and sharpness.
  • Cinema: Optimizes video for watching videos.
  • Sport: Emphasizes dynamic video and primary color for optimum sports watching.
  • Game: Provides fast response speed for fast gaming system.
  • User: This mode allows you to adjust the video quality settings manually. You can adjust the following.
    • Contrast: Increase or decrease the gradient of the video signal. You may use Contrast when the bright part of the picture is saturated.
    • Brightness: Adjusts the base level of the signal in the picture. You may use Brightness when the dark part of the picture is saturated.
    • Sharpness: Adjusts the level of crispness in the edges between the light and dark areas of the picture. The lower the level, the softer the image.
    • Color: Adjusts intensity of all colors.
    • Tint: Adjusts the balance between red and green levels.
    • Color Temp: Set to warm to enhance hotter colors such as red, or set to cool to enhance cooler colors such as blue.

Picture Improvement Technology (Advanced Control): Advanced Control allows you to adjust some of the advanced video features of the LG Plasma TV.

  • Dynamic Contrast: Adjusts the contrast to keep it at the best level according to the brightness of the screen. The picture is improved by making bright parts brighter and dark parts darker.
  • Dynamic Color: Adjusts screen colors so that they look livelier, richer and clearer. This feature enhances hue, saturation and luminance so that red, blue and green will look more vivid.
  • Noise Reduction: Reduces screen noise without compromising video quality.
  • Gamma: You can adjust the brightness of dark areas and middle gray level areas of the picture.
  • Black Level: Sets the black level of the screen to the proper level.
  • 24p Real Cinema (Film Mode): Makes video clips recorded in a film look more natural by eliminating judder effect.
  • Color Gamut: Maximizes the utilization of color to increase color quality.
  • Edge Enhancer: Shows clearer and distinctive, yet natural corners of the video.
  • Color Standard: Converts the color of a different video to HD color.
  • White Balance: This function is used to adjust the overall color of the screen.
  • Color Management System: A tool that allows you to make adjustments by using test patterns; this does not affect other colors, but can be used to selectively adjust the 6 color areas (Red/Green/Blue/Cyan/Mgt/Yellow).

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. Sophisticated and detailed calibrations can be made through the ISFccc mode. Detailed calibration requires a licensed technician. 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.
  • Orbiter: Orbiter may help prevent ghost images. However, it is best not to allow any fixed image to remain on the screen. To avoid a ghost image on the screen, the image will move every 2 minutes.
  • 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.
  • White Wash: White Wash removes ghost images from the screen. Use sparingly. Watch the TV normally for a while before using this feature to see if the ghost image disappears on its own.

Audio Features

Invisible Speakers: The LG 50PK550 contains a unique invisible speaker system, tuned by renowned audio expert, Mr. Mark Levinson. The TV's speakers are embedded in strategic spots behind the front-cabinet and use minute vibrations to turn the entire front bezel into the speaker system. The result is a clean, polished look, and enhanced audio by increasing the "sweet-spot", giving a wider and richer sound field.

Sound Modes: Sound Mode lets you enjoy the best sound without any special adjustment using factory presets. Standard, Music, Cinema, Sport, and Game are preset for optimum sound quality. There is also a User Mode which allows you to adjust the television's Bass & Treble.

Clear Voice II: Clear Voice II enhances and amplifies the frequency range of the human voice to help keep dialogue audible when background noise swells.

Infinite Sound: Infinite Sound is a patented LG proprietary sound processing technology that delivers immersive 5.1 surround sound with just two front speakers.

Auto Volume: Auto Volume makes sure that the volume level remains consistent whether you are watching a commercial or a regular TV program. Because each broadcasting station has its own signal conditions, volume adjustment may be needed every time the channel is changed. This feature allows users to enjoy stable volume levels by making automatic adjustments for each program.

Digital Audio Output: An optical digital output is provided to allow you to connect the unit to a surround processor. The TV's digital audio output terminal outputs a Dolby Digital or 2-channel down-mixed PCM signal for use with an external Dolby Digital decoder or other external audio system with an optical audio input.

Note: There is no analog audio output.

PC/USB Functions

This input consists of a stereo mini-jack and an analog RGB (D-Sub 15-pin) jack. This jack allows you to connect a personal computer with a D-Sub 15-pin output. When using the RGB (D-Sub 15-pin) jack, you must use the PC Audio 3.5mm input for your audio connection. Any HDMI input can also be used with a computer. The TV can be set to automatically adjust to the video signals received, or you can use the setup menu to adjust the screen's Position, Size, and Phase.
