About the LG UBK90

Get the best out of your 4K TV

Since I upgraded to my LG OLED 4K TV, everything I watch looks better. But I geek out the most over shows and movies in true 4K. They just seem to pop off the screen. And the LG UBK90 4K Blu-ray player will play Ultra HD Blu-ray discs with Dolby Vision — the absolute best-quality video source available today.

Get the best out of your 4K TV

Since I upgraded to my LG OLED 4K TV, everything I watch looks better. But I geek out the most over shows and movies in true 4K. They just seem to pop off the screen. And the LG UBK90 4K Blu-ray player will play Ultra HD Blu-ray discs with Dolby Vision — the absolute best-quality video source available today.

Ready for the best HDR formats

Ultra HD Blu-ray discs with HDR (High Dynamic Range) allow compatible TVs to display extremely bright and dark black picture content together within the same image. HDR content makes for serious eye candy on my new OLED TV — it stands out even among other, stellar-looking 4K videos.

And this player supports the required HDR 10 format, and the more sophisticated Dolby Vision format. Dolby Vision is one of the reasons I ended up going with the LG OLED. Dolby's dynamic system can adjust brightness and color levels on a scene-by-scene basis.

Netflix has a bunch of shows in Dolby Vision, and some of them look so realistic and vibrant that it actually adds to the storytelling. Take the brutal Western show Godless: the beautiful yet nightmarish landscape is practically one of the characters. Watching sunlight peek over a mountain and spill over the dusty terrain with true-to-life shading is truly a sight to see.   

Top movie sound formats and flexible connections

This player has built-in support for the highest-quality surround sound formats, like Dolby® TrueHD and DTS Master Audio™. It also plays Dolby Atmos®-encoded discs. You simply set the HDMI audio output to "bitstream" when connected to an Atmos-capable receiver. 

There are two HDMI outputs: one for sending audio to your home theater receiver and one for video directly to your TV. That means you can still play sound through receivers that don't have a free HDMI input that's HDCP 2.2 compatible. You can also use an optical digital connection to get surround sound from the player to your receiver.

Dual-band Wi-Fi means smooth 4K video streaming

Along with playing discs, you can use the UBK90 to stream Netflix® and YouTube. These are the two video services that offer the most 4K content available right now. And this player's dual-band Wi-Fi gives you the strong connection needed for streaming 4K. (We recommend having an internet speed of 20Mbps or faster for 4K streaming.)

Disc & USB Compatibility

Disc Compatibility: The LG UBK90 Ultra HD Blu-ray disc player is compatible with many disc types.

Disc Type Disc Description
CD CD-Audio, CD-R, CD-RW

Ultra HD Blu-Ray: Ultra HD Blu-ray provides these key features and advantages over standard Blu-ray.

  • 4K Resolution: Ultra HD Blu-ray supports resolutions of up to 3840 x 2160 pixels. That's 4x as many pixels as Full HD televisions, and 27x as many pixels as Standard Definition televisions
  • Wider Color Gamut: Ultra HD Blu-ray can display over 75% of the visible color spectrum; this is known as "Wider Color Gamut". That's more than twice the color range of current Ultra-HD TVs.
  • HDR (High Dynamic Range): Ultra HD Blu-ray also supports High Dynamic Range (HDR) video. Dynamic range is the difference between the brightest whites and the darkest blacks on screen. HDR means that scenes with high contrast can be shown with much greater clarity and detail.
  • Smooth, Realistic Motion: Ultra HD Blu-ray supports progressive frame rates of 24, 25, 50 and 60 frames a second, enabling smoother, more realistic motion.
  • Greater Capacity & Speed: Ultra HD Blu-ray Discs will be available in a dual layer 66 gigabyte disc and a triple layer 100 gigabyte disc. Ultra HD Blu-ray can stream video up to a maximum of 108/128 Mbps for 66Gb and 100Gb discs.
  • Backward Compatible: Ultra HD Blu-ray players will play all current Blu-ray Disc & DVD content. When connected to a current Ultra-HD TV television, the player will output a standard Ultra-HD TV signal. Ultra HD Blu-ray players will support existing Blu-ray media, as well as provide down conversion and HDR to SDR conversion functionality to match the connected television's capabilities.

Note: Like standard BD, Ultra HD Blu-ray discs use region codes. The region code on your disc must match the region code on your player, otherwise the disc will not play. This Blu-ray player is region A and DVD region 1. Blu-ray Disc uses the Advanced Access Content System (AACS) to prevent unauthorized recording of copyrighted material.

Firmware & Software Updates: As Blu-Ray technology continues to evolve, new disc types with enhanced functionality will become available. In order for you to enjoy this new functionality, you will likely be required to update the firmware in your player. These firmware updates will become available for downloading from the Internet. The player's Software Upgrade menu allows you to upgrade the player's software & firmware for these performance improvements & additional services. You can upgrade via Network or USB.

Note: Visit LG's Support Site for the latest firmware/software updates.

USB Port: The front-panel USB (type-A) port supports playback of a variety of video, photo, and audio files on a USB MSC (mass storage class) or MTP (media transfer protocol device). Compatible MSC devices include USB thumbdrives or external HDD(s) formatted in FAT32 or NTFS. An external HDD will require a separate power supply. Compatible MTP devices include Android smartphone & tablets (running Android OS 4.0 or later). The player can recognize up to 2,000 total files/folders.

Note: The USB port is not compatible with Apple iOS devices, USB hubs, card-readers, or computers.

Media File Formats: The LG UBK80 supports the following video, photo, and music files recorded onto BD-RE, BD-R, DVD+RW, DVD+R, DVD-RW, and DVD-R discs; or downloaded onto a USB MSC/MTP device.

Media Type Format
Video MPEG 1/2/4, AVI, MKV, WMV, XVID
Photo JPEG, PNG, GIF, MPO (4000x3000 max)
Music MP3/WMA (up to 48kHz), AAC/OGG (up to 96kHz), AIFF/FLAC/WAV (up to 192kHz)

Video Section

Ultra HD Premium: The LG UBK90 garners UHD Alliance's ULTRA HD PREMIUM logo which identifies products and services that meet or exceed strict performance levels for 4K resolution, high dynamic range (HDR), and wide color spectrum.

HDMI 2.0a Output + HDMI Audio Only Output: The LG Ultra HD Blu-ray player is equipped with dual HDMI outputs for separating audio and video signals (the "Sub" HDMI output does not output video signal). The HDMI-1 2.0a output can be used to carry both video and digital audio all in one cable. You can choose to use the HDMI-2 1.4 output to send audio only to your AV receiver and the HDMI 2.0a to send only video to your HDTV. The HDMI output resolution can be set to 480p, 720p, 1080i, 1080p, 2160p (4K), or Auto.

Note: There is no analog video output.

HDR Compatible: The LG UBK90 Ultra HD Blu-ray player supports HDR (High Dynamic Range) video - including the HDR10 and Dolby Vision (future firmware update) formats. 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.

  • HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
  • Dolby Vision: Unlike HDR 10 which contains static metadata, Dolby Vision adjusts brightness, color, and contrast automatically for each scene (supports 12-bit color and 10,000 nits). 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. 
Note: Please use a premium high speed HDMI cable with 18 Gbps and above to view Ultra HD and HDR content.

3D-Ready: The LG UBK90 UHD Blu-ray disc player supports 3D playback of high-definition  (720p/1080p) 3D Blu-ray discs when connected to a 3D-Ready HDTV via HDMI, along with wearing a pair 3D vision glasses.

x.v.Color: This player can playback AVCHD discs using the x.v.Color format. x.v.Color offers a wider color range than normal DVD camcorder discs.

Display Mode: When the player's resolution is set to 1080p or 2160p, you can select the 24Hz mode for smooth presentation of film material (1080p or 2160p/24 Hz) with a HDMI-equipped display compatible with 1080p or 2160p/24 Hz input. You can select a 60Hz mode for video material.

TV Aspect Ratio Settings: You can select the aspect ratio according to your television. Choose from 4:3 Letter Box, 4:3 Pan Scan, 16:9 Original, or 16:9 Full. You cannot select 4:3 Letter Box or 4:3 Pan Scan when the Blu-ray player's resolution is et to 720p or higher.

Picture Adjustments: The following picture adjustments are available - Contrast, Brightness, Color, & Sharpness.

Bonus View: The Bonus View feature provides picture-in-picture capability with select Blu-ray Disc titles. You can view addition content (such as director/actor commentary) in a small display window while the movie is playing.

Audio Section

Surround Sound Decoders: The LG UBK90 UHD Blu-ray player has built-in Dolby Digital and DTS surround processors with support for Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution, and DTS-HD Master Audio.

1 question already asked

Does the 4K TV connected to must support Dolby Vision or does Dolby Vision work with any TV? For example the SONY XBR-85X850F or XBR-85X850G the 850F does not support Dolby Vision according to the SONY web site. Is Dolby Vision a big deal? Thanks
[ Vincent  Apr 27, 2019 ]

Your TV needs to support Dolby Vision as well to get the best possible picture. Dolby Vision itself enhances the quality of the picture like color, contrast, etc..
[ CRAIG A  May 05, 2019 ]
Vincent, my thoughts on this are that if you have a tv that is Dolby 4K capable and need a new player then sure buy a DVD player that supports Dolby Vision. Virtually all of my Dolby Vision I watch is either on the high end package of Netflix that supports Dolby Vision or Amazon Video and my Dolby capable TV takes care of it. It's really awsome when the source is Dolby Vision! If you don't have the Dolby Vision capable tv then forget it. I have never rented a Dolby DVD to date and will when Redbox starts distributing them. But for now the Dolby DVD player is used for standard blu Ray only.
[ DIANE  May 05, 2019 ]
TV must support Dolby Vision
[ Thomas  May 05, 2019 ]
I mean a 12 bit 2.1 tv
[ JAMES A  May 05, 2019 ]
Yes a 4K tv must support Dolby Vision in order for Lg blu ray player with Dolby Vision to work with 4k Blu Ray discs that have Dolby Vision.The image quality is improved with a Dolby Vision blu ray disc.In the future when there will be 12 Bit 2.2 TV will show the the true HDR and Dolby Vision.
[ JAMES A  May 05, 2019 ]
The tv must support dolby Vision
[ JOSEPH C  May 05, 2019 ]
