Our take on the LG 55SJ8500

If you're going to upgrade from HD to 4K, do it right and choose a TV with solid support for HDR (High Dynamic Range), too. The 55SJ8500 combines 4K and HDR to deliver pinpoint picture detail, a richer color palette, and more lifelike contrast.

Make the leap to quality 4K

If you're going to upgrade from HD to 4K, do it right and choose a TV with solid support for HDR (High Dynamic Range), too. The 55SJ8500 combines 4K and HDR to deliver pinpoint picture detail, a richer color palette, and more lifelike contrast.

To see this TV at its very best, connect it to an Ultra HD Blu-ray player and watch a 4K disc. And thanks to LG's advanced video processing, every other source you watch will look clearer and more vibrant than you've ever seen it.

LG gives the HDR experience extra oomph

HDR allows compatible TVs to display deeper blacks and brighter highlights. Special instructions called "metadata" are embedded in the signals of HDR-enhanced video — both Ultra HD Blu-ray discs and streamed 4K video from services like Netflix® and Amazon Instant Video. These instructions tell the TV when to get extra dark or extra bright.

The 55SJ8500 supports the two most common HDR formats: HDR 10 and Dolby Vision™. HDR 10 is a static system which establishes the contrast settings at the beginning of a movie or TV show and maintains them. Dolby Vision is a dynamic system that can adjust brightness in response to the video signal on a scene-by-scene or even frame-by-frame basis. LG's Active HDR circuitry analyzes and optimizes HDR 10 content scene by scene, bringing it closer to what Dolby Vision achieves.

A bigger viewing sweet spot makes this TV a crowd-pleaser

If you frequently watch TV with a bunch of friends or family, you'll probably want your new TV to provide good off-axis viewing. That's typically one of the biggest weaknesses of LCD TVs, but LG has an effective solution: their IPS panel technology. It keeps picture contrast and color looking crisp even for viewers seated around to the sides of the screen. The trade-off is contrast and black levels that aren't quite top-notch. It means the 55SJ8500 is best enjoyed with at least some room lights on.

Smart TV features made point-and-click easy

The 55SJ8500's built-in web apps give you instant access to a nearly limitless selection of entertainment. The latest version of LG's colorful webOS interface lets you customize your home screen to quickly get to the apps you use most. And LG's motion-sensing Magic Remote is simple and fun to use. You can point, click, scroll and even speak into the remote to find exactly what you want, searching across apps, movies, TV shows and the web.

    A great TV! I might knock it down a 1/2 for being a little tricky/hard to set up but that makes it essential to reading the manual thoroughly!! Great product and great price from Crutchfield!



    Not the OLED, but the next best thing.

    Matt from Somerset, PA on 10/13/2017

    Crutchfield Customer Review (What's this?)

    I did a lot of research before finally deciding on this TV. For more money you can get the OLED, but this TV is the next best thing. I've watched old movies from the 60s that are black and white, and even those videos are up scaled and the picture is extremely clear. I can't comment on the sound because we never use the sound. We have everything hooked into an AV receiver and the sound goes straight to the speakers.

    Pros: 120 refresh rate, 4K


    Good deal

    Arni from Charleston, SC on 9/13/2017

    Crutchfield Customer Review (What's this?)

    I'm really happy with this TV. I wanted to get the OLED but when this TV came on sale I took the chance. It is likely that the picture isn't quite as good as an OLED but at half the price I am extremely impressed.

    Pros: Great price. Very sharp picture and bright room performance. Good colors. Very wide viewing angle. Have been using the Smart features and like them a lot; may decide not to upgrade my Roku.

    Cons: Not as good blacks as the OLED but was on sale for half the price.

    Video Features

    Nano Cell Display Technology: The LG Super UHD TV with Nano Cell technology delivers consistent colors at wider viewing angles. LG's proprietary Nano Cell technology is a breakthrough in display technology that advances the LCD TV viewing experience by combining an expanded color gamut with the ability to more accurately create those colors, resulting in superior picture quality regardless of viewing angle. A Nano Cell display offers a technological advantage by employing uniformly-sized particles approximately one nanometer in diameter to create more subtle, accurate colors that can be viewed from wider angles than other LCD TVs.

    More Color, Contrast, & Brightness: The LG Super UHD TV delivers superior color, contrast & brightness through its Nano Cell display, local dimming and LG's Ultra Luminance technology.

    • Billion Rich Colors w/ True Color Accuracy: The Nano Cell display reveals a billion lifelike colors, 64x richer than conventional TV. This ability to produce a full spectrum of color results in superior picture quality. True Color Accuracy uses advanced color mapping technology to effectively correct any color distortions and delivers a picture that is accurate, natural, and lifelike.
    • Local Dimming: The TV provides even greater control of brightness & contrast through local dimming to deliver deeper blacks, amazing clarity, and color detail. LG's local dimming technology analyzes the signal of the input video by areas of the screen, and then adjusts the backlight to improve the contrast ratio. This increased contrast ratio in turn enhances overall picture quality with greater clarity, plus bolder colors.
    • Ultra Luminance: LG's new Nano Cell Super UHD TV uses improved Ultra Luminance technology to deliver brighter, crisper image highlights. Ultra-HD picture quality becomes even more dynamic with an extended range of brightness (up to 1000 nits), thanks to LG's Ultra Luminance technology. By enabling higher peak brightness and an enhanced contrast ratio, Ultra Luminance makes 4K & HDR images even more striking.

    IPS Panel: LG's IPS (In-Plane Switching) panel makes any seat the best in the house, with a clearer and more consistent image at wide viewing angles compared to conventional screens. IPS delivers authentic colors, virtually identical to the original image. Witness colors as true-to-life as nature intended, vibrant across even a large screen, with the stunning clarity of 4K resolution.

    TruMotion 240Hz: The Super UHD TV employs LG's proprietary TruMotion 240Hz backlight scanning system to enhance the TV's 120Hz native panel refresh rate to reduce blur and yield crisper details; even during the most high-action sequences - from sports to action movies.

    Ultra HD 4K Resolution w/ Upscaler: The LG Super UHD TV has a display resolution of 3,840 x 2,160 (4K) and will display all video at that resolution through its built-in upscaler, regardless of input signal. 4K provides four times higher resolution than current 1080p high-definition TVs with a total of 8.3 million pixels. Its detail is so vivid and crisp, even when viewed from close distances; it's nearly impossible to discern a single pixel, even from inches away. Enjoy incredibly flawless images, vivid colors, and picture details as never before. More benefits of Ultra-HD 4K include:

    • Greater Sense Of Depth: At 4K, distant objects in a  scene can be rendered with greater clarity than at 2K, with more nuances of light and shadow and focus for a greater sense of perceived  depth.
    • Better Color: Because pixels are units of colored light, their greater quantity in 4K enables more layered transitions and subtler gradations of tones, so the hues we see up on screen will be truer to what we see in nature.
    • Sit Even Closer: 2K HD TVs carry a recommended viewing distance of three times (3X) the TV screen height, but with a 4K display you can move in to one-and-a-half times (1.5X) screen height without exposing individual pixels. Sitting closer better fills your field of vision, assuring total immersion in whatever you're watching.

    HDR (High Dynamic Range) Video: The LG Super UHD TV supports a variety of HDR technologies including HDR10, HLG HDR, and Dolby Vision. HDR reproduces a greater dynamic range of luminosity or brightness levels, bringing greater contrast & wider color spectrum to the screen. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. Previously hidden areas of dark shadow and sunlight are now full of clarity and detail.

    • Active HDR (for HDR10 & HLG): Active HDR analyzes and optimizes High Dynamic Range video content scene-by-scene for an even more striking, more breathtaking HDR video experience. This process allows the TV to offer the best picture possible, even when playing HDR10 content which only contains static metadata, or HLG content which uses no metadata at all.
    • Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses not metadata, Dolby Vision adjusts brightness, color, and contrast automatically for each scene. Dynamic metadata carries information that maps every image to your TV's display capabilities, so you see more of what the content creator intended. As a result, Dolby Vision delivers incredible brightness, color, contrast, detail, and dimensionality. 
    • HDR Effect: The TV's new HDR Effect feature raises image quality for SDR content to near HDR quality. With the HDR Effect feature, SDR images are processed frame-by-frame to improve brightness in specific areas, enhance contrast ratios and render more precise images.

     Video Inputs: The LG Super UHD television features HDMI 2.0a and Composite video inputs. All of the television's video inputs are displayed at 3,840 x 2,160 (4K).

    • HDMI 2.0a: The four HDMI 2.0a inputs will accept 4K (60/30Hz), 1080p (60/24Hz), 1080i, 720p, and 480p video signals. The HDMI inputs not only allow you to connect your Blu-ray/DVD player or Satellite/Cable receiver to the TV, but also a laptop or computer. The television's HDMI inputs do not accept 480i video signals.
      • HDCP 2.2: HDCP 2.2 is supported by all of the TV's HDMI inputs. HDCP 2.2 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with 4K Blu-ray players and 4K Satellite/Cable providers.
      • 4:4:4 Color Subsampling: All of the HDMI inputs will support up to 4:4:4 chroma subsampling for full color data rendering of 4K video (30/60fps). With 4:4:4 color, luminance (brightness) and chroma (color) are sampled at the same rate, resulting in an RGB color palette as big as the video sampling rate for a video image with more total colors, plus greater color accuracy and detail. You will need to enable this feature in the menu. 4:2:2 (30/60fps) and 4:2:0 (60fps) are also supported by any of the HDMI inputs, by default.
    • Composite Video: There is a single composite video input that will accept 480i only. The composite video input consists of a 3.5mm AV minijack and comes with a composite video/stereo RCA adapter. This TV does not contain a component video input.
    Note: The LG TV features a built-in over-the-air HDTV (ATSC) and Clear QAM tuner, so you don't need a separate set-top box to receive and decode over-the-air HDTV/SDTV or unencrypted Digital Cable signals (up to 1080i); subscription still required to receive cable channels. A single RF-type coaxial input is use to connect an external indoor/outdoor antenna (sold separately).

    Picture Settings: The LG Super UHD TV provides preset, user, and expert adjustment of the television's picture settings.

    • Picture Size: You can select a different aspect ratio depending on input source (analog broadcasting, digital broadcasting, video input).

      • Expert: the TV is ISFccc Ready and contains the detailed standards necessary for professional calibration of brightness, contrast, tint, sharpness, color levels and much more to meet local lighting conditions for both day and nighttime viewing; the EXPERT/ISFccc mode allows an expert to fine-tune the picture quality using a specific image
      • Technicolor (requires future firmware update): users will benefit from Technicolor's renowned color science, applied to the majority of Hollywood's premium content, through Technicolor Expert Mode, which will be added in late 2017 (through a network firmware update) and is designed to deliver the most accurate colors
    • Advanced Picture Control: The TV also offers more advanced picture settings.
      • 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

    Magic Zoom: Magic Zoom enables you to magnify objects and letters anywhere on the screen without any degradation in picture quality, using the included Magic Remote.

    Audio Features

    ARC (Audio Return Channel): The Audio Return Channel of the TV's HDMI 2 input enables the television, via a single HDMI cable, to send audio data "upstream" to your AV receiver; increasing user flexibility and eliminating the need for any separate S/PDIF audio connection. This feature allows audio to be sent from the television to your AV receiver through the same HDMI cable already being used to send audio/video to the television. This eliminates the need for extra cables connected to the TV. ARC allows audio from the TV tuner, Network connection, inserted USB device, HDMI inputs, or any analog connected device to be heard through your ARC compatible AV receiver via the television's HDMI ARC input.

    • The audio from the TV's tuner, HDMI inputs, LG Smart TV apps, and USB ports can pass as Dolby Digital Plus, Dolby Digital, DTS, or 2ch PCM.
    • Analog connected & DLNA compliant devices will be output audio at 2ch PCM only.
    Note: Both the television and the receiver must support ARC for this function to work properly. When connecting an AV receiver that is compatible with Audio Return Channel (ARC), connect it to the TV's HDMI 2 input. If connecting a system that is incompatible with Audio Return Channel (ARC), an additional audio connection via Digital Audio Out (Optical) is necessary.

    Digital Audio Output: The optical digital output terminal will output Dolby Digital/DTS (when available) or 2 channel PCM. The digital optical output terminal only sends an audio signal in Dolby Digital/DTS when receiving Dolby Digital/DTS surround sound from a digital broadcast channel through the tuner, network apps, HDMI inputs, and USB ports on the TV. The optical digital audio output will only output in 2ch stereo from sources connected to the TV via stereo RCA.

    Note: You can choose to turn the television speakers off or leave them on with the TV's optical digital output active.

    LG Sound Sync w/ Bluetooth: Thanks to the TV's LG Sound Sync and built-in Bluetooth, you can pair a single set of Bluetooth headphones or one Bluetooth speaker (or single pair of speakers) with the LG Super UHD TV. You are able to stream audio from any of the TV's built-in sources or connected sources. The TV's built-in speakers and audio outputs will be deactivated when streaming audio to Bluetooth headphones or speaker. The Bluetooth audio output's volume is variable, so volume of your Bluetooth speaker will need to be controlled by both the TV and the Bluetooth speaker for adequate volume level.

    Note: Not guaranteed to be compatible with all Bluetooth devices.

    Harman/Kardon Sound Design: The TV's onboard speaker system has been designed by Harman/Kardon to provide rich, cinematic sound in your living room.
