2015 LG 4K UHD LCD TVs
Monday, December 29, 2014 at 6:00PM Updated on August 19, 2015: updated models, availability, and specs
Ultra-high definition (UHD) televisions are here to stay, and projections indicate that by 2018 every TV 55-inches and larger will feature UHD resolution! LG Electronics' 2015 LCD (liquid crystal display) lineup includes an impressive array of new 4K UHD TVs that aim to delight the senses with enhanced color, sound, and designs.
LG's 2015 4K UHD LCD televisions include something for everyone with a wide range of screen sizes and features that will tempt the value conscious and videophile alike. Unlike LG's main competitor (some company with a name that starts with 'S'), all of its LCD TVs are curve-free and use IPS panel technology for improved off-axis viewing. LG's 2015 LCD lineup also goes completely edge-lit LED with no announced models incorporating full-array backlighting although premium models will feature edge-based local dimming for enhanced picture contrast.
Positioned as the best value in LG's 4K LCD lineup, the UF6800 eliminates the sometimes unwanted or unneeded extras like a fancy remote and 3D viewing. The UF6800's smart TV capabilities are further enhanced with the latest webOS 2.0 update. A unique feature of the UF6800 is its subpixel structure that adds white to the traditional RGB (red, green, and blue) pixel composition. Each white subpixel is shared between adjacent groups of RGB subpixels and this has generated some controversy among resolution purists who question if this layout constitutes a true UHD display. Other specs of the affordable UF6800 series include:
- Screen sizes: 65-inches, 55-inches, 49-inches, 43-inches
- 60Hz refresh rate (65-inch model is 120Hz)
- RGBW subpixel structure (RGB + White)
- Built-in WiFi
- webOS 2.0
- Quad core processing
- 2 HDMI ports
Originally announced as part of the UF7700 series, these smaller sized screens should prove to be a popular option with workstation users and anyone wanting an affordable 4K UHD smart TV. Like the UF7700 series, the UF7600 series keeps the price low by eliminating 3D viewing support as well as the Harmon Kardon enhanced audio featured in some of LG's more expensive 2015 offerings.
The UF7700 series offers the greatest selection of screen sizes among LG's 2015 televisions, and it looks to strike a good balance of performance and value. The UF7700 lacks the 3D viewing and Harmon Kardon enhanced audio of more expensive models, but its other specs will tempt many would-be owners:
- Screen sizes: 79-inches, 70-inches, 65-inches, 60-inches
- 120Hz refresh rate (60 inch model is 240Hz)
- Edge-lit local dimming backlight system
- New 5th generation Magic Remote
- Built-in WiFi
- webOS 2.0
- Quad core processing
- 3 HDMI ports
2015 Vizio M-Series 4K UHD TV Preview
The UF8500 may be the most visually appealing 4K UHD LCD in LG's 2015 lineup as it features the company's Cinema Screen design with an ultra thin bezel that makes its picture truly stand out. The UF8500's other impressive specs leave little to be desired save, perhaps, for even larger screen size options:
- Screen sizes: 65-inches, 60-inches
- 120Hz refresh rate
- Edge-lit local dimming backlight system
- New 5th generation Magic Remote
- Harmon Kardon enhanced audio (ULTRA Surround System)
- webOS 2.0
- Quad core processing
- Passive 3D technology
- 3 HDMI ports
UF9400
If you are looking for an LCD that can accurately display rich, deeply saturated colors like that of DCI-P3 encoded sources, then the LG UF9400 appears ready and able. The UF9400's ColorPrime with Quantum Dot (QD) technology expands the TV's palette by 30% compared to previous models making it ideal for accurately displaying wide gamut video, and its cadmium-free QD materials are safe for the environment.
The well-specced UF9400's also features:
- Screen sizes: 65-inches, 55-inches
- 120Hz refresh rate
- 8-bit LCD panel
- New 5th generation Magic Remote
- Harmon Kardon enhanced audio (ULTRA Surround System)
- webOS 2.0
- Quad core processing
- Passive 3D technology
UF9500
LG's flagship 4K UHD LCD television brings an OLED-like slim panel design that measures only 0.33" thick near the top and 1.37" across the lower portion of the TV's chassis. The UF9500 also introduces LG's new ColorPrime LED technology that uses white LEDs with an enhanced phosphor plus an optimized color filter to expand the TV's color palette by 25% bringing it close to the wide gamut of the DCI P3 specification.
The UF9500 specs include:
- Screen sizes: 79-inches, 65-inches, 55-inches
- 120Hz refresh rate
- Edge-lit local dimming backlight system
- New 5th generation Magic Remote
- Harmon Kardon enhanced audio (ULTRA Surround System)
- Integrated Auditorium Stand for improved audio performance
- webOS 2.0
- Deca core processing (quad core for 79 inch model)
- Passive 3D technology
This refreshed model from 2014 is for the home theater enthusiast that want to go BIG! The UB9800 series will offer a good balance of features, large screen sizes, and price.
- Screen sizes: 98-inches, 84-inches, 79-inches, 65-inches
- 120Hz refresh rate
- Edge-lit local dimming backlight system
- New 5th generation Magic Remote
- Harmon Kardon enhanced audio (ULTRA Surround System)
- webOS 1.0
- Dual core processing
- Passive 3D technology
UC9
Another holdover from last year that's making an appearance in 2015 is the 105-inch LG UC9. This gigantic-sized curved screen TV features a 21:9 aspect ratio that translates into a pixel resolution of 5120 x 2160. With this much screen to work with, it's no surprise that the UC9 is fully loaded with excellent features including:
- Local dimming
- IPS panel technology
- Harmon Kardon enhanced 7.2 channel speaker system (150W)
- HEVC/H.264 decoding
- Passive 3D technology

Review: Samsung H6400 Smart TV
Tuesday, December 16, 2014 at 7:58AM 
The Samsung H6400 Series Smart TV impressed me right out of the box with accurate color and grayscale performance using its factory calibrated Movie picture preset. The H6400's well-contrasted imagery derived from its ample maximum light output (391 cd/m2) that's ideal for well-lit rooms and good black levels for optimized dark room viewing. Compared to the similarly styled H6350 series, the H6400 adds 3D, improved motion resolution, and the impressive RF-linked Smart Remote Control. If you don't need or want the H6400's extras, then the H6350 presents an even better value.
Size and style
I reviewed the 55-inch version (UN55H6400) and other available screen sizes include 48-inches, 50-inches, 60-inches, and 65-inches. The H6400's thin bezel design (0.56 inches along the top and sides) accentuated its 1080p 120Hz LCD panel. A swivel base stand proved useful, and the TV's chassis is compatible with standard wall mount hardware.
Processing prowess
Samsung's superior video processing gives the H6400 effective film-mode detection for maximum detail and deinterlacing that's free of unsightly jagged edges. I also appreciated the TV's Auto Motion Plus feature that reduced motion blur with video sources like sports programming without altering the filmic look of 24fps material (most movies and TV shows). Most LCDs cannot reduce motion blur without also also smoothing the on-screen motion of movies to the point they appear soap opera-like.
App goodness
The TV's quad core processor made for fast start up times and speedy app performance. The selection of apps on Samsung Smart TVs continues to be the most comprehensive among manufacturers, and I was please to see a recent update for Amazon Instant Video add support for the remote's precise cursor control - a first among third party apps and something Netflix should have added long ago. The H6400 flawlessly streamed 1080p video from popular services over its WiFi link, and a bandwidth speed test using its built-in web browser revealed no problem saturating a 60Mbps/6Mbps (down/up) connection. In a pinch, Bluetooth mouse and keyboard support effectively transform the H6400 in to a convenient Internet workstation.
Not quirkless
Similar to Samsung's otherwise awesome 4K UHD HU8550 television (read review), the H6400 overscaned 720p broadcast channels like ABC and Fox when using its built-in over-the-air (OTA) tuner - 720p input via the TV's four HDMI ports could be configured to not cut off the edges of the video picture. Also, navigating the H6400's channel guide was annoyingly sluggish.
The H6400's excellent color accuracy (note the CalMAN Color Checker result below) was tempered by benchmark tests that revealed a slight loss of fine color detail with component video (YCbCr) encoded sources (most HDMI video devices). RGB encoded HDMI input didn't exhibit this loss.
Audio quality from the H6400's down-firing stereo speakers was surprisingly weak sounding. Enabling the TV's DTS TruSurround sound mode did improve the listening experience, but I recommend adding a good soundbar/soundstand for a more immersive home theater experience!
Bottom line
Everyone appreciates a great deal on good technology, and the Samsung H6400 Series Smart TV is an above average HDTV with picture performance comparable to TVs that cost much more. In my time with the H6400, Samsung has pushed a couple of firmware update, and I'll update this article if any future updates address the few quirks noted above.

Preview: Sharp AQUOS 4K UD27 Line
Thursday, October 30, 2014 at 1:45PM 
Updated on January 16, 2015: clarified HDCP 2.2 support
Sharp was once the only option for premium 1080p LCD televisions, and now its latest line of 4K screens is promising finely tuned imagery and quality design features at equally attractive prices. The Sharp AQUOS 4K Ultra HD TVs feature THX 4K certification that involves more than 400 lab tests to help ensure an accurate and pleasing picture. Framed in aluminum trim, these new 4K TVs are part of Sharp's UD27 line and are currently available in screen sizes of 60-inches and 70-inches.
The UD27's screen features the latest 4K display technology, and the TVs incorporate features that should please anyone looking to futureproof a 4K display investment:
- 120Hz refresh rate with backlight scanning/blinking for improved motion resolution performance
- Four HDMI 2.0 ports that accept 4K video signals at up to 60 frames per second (4K60)
- One 4K HDMI input (port #3) accepts Y'CbCr 4:4:4 and the other three accept Y'CbCr 4:2:0 (chroma subsampling)
- Only HDMI port #4 is HDCP 2.2-enabled (also MHL-enabled) for use with copy protected 4K sources like the Sony FMP-X10 (read my review)
- H.265/HEVC-enabled for 4K video streaming (Netflix)
- Simplified single screen and mobile app (Android and iOS) for control, content discovery, and search
I'm curious to see if the UD27 will delivery good motion resolution with video originated from 24fps material (most feature movies) without overly smoothing the look of on-screen action. And for supersized PC gaming, I'm interested in testing its HDMI ports for compatibility with 1080p input at 120Hz. A review sample has been requested - stay tuned!

Review: DVDO Air3C-Pro
Tuesday, October 21, 2014 at 9:51PM 
In the box
The Air3C includes everything needed for most installation scenarios. The similarly sized transmitter and receiver are slightly larger than a deck of playing cards and weigh 107g (3.75oz) each. Also in the box are USB power adapters, USB cables, and a pair of HDMI cables (4 feet long each).
Simple setup
Air3C setup is as simple as connecting the HDMI cables and adding USB power to the transmitter and receiver. After the units automatically make the initial connection (aka "mate"), they are able to reconnect within a few seconds after powering up.
Mounting options
The Air3C units have two holes for affixing them onto a flat surface with screws or similar fasteners. An included clip-on bracket and adhesive Velcro pads can be used to attach the receiver to the back of a TV. Ideally, the units will be positioned within line-of-sight, but the Air's 60GHz radios can bounce signals off of a wall or ceiling to maintain a connection with slightly obscured transmitter and receiver placement.
Robert's Favorite Home Theater Gear
Main features
In addition to the Air3C-Pro, DVDO offers a more budget-friendly non-pro version. Both models feature identical wireless technology and basic performance features that include:
-
Up to 1080p60 HDMI video transmission
-
3D video
-
Up to 7.1 channels of HD audio
-
USB powered
-
Very low latency
-
CEC passthrough
What makes the Pro version unique is a software configuration tool that can confirm connection status, evaluate signal performance, and create custom device parings including whitelisting for restricting connections between specified units.
The software also features firmware update capabilities for both versions should the need arise.
Efficiency improvement
The biggest improvement of the Air3C compared to the original DVDO Air is that it can be freed from a wall outlet! The unit still requires a separate power source, but improvements in efficiency enable it to siphon juice from any nearby USB port that is rated for at least 5V/1A output.
In the lab, the Air's receiver was powered perfectly by the four USB-equipped TVs I tested it with. Adequate USB power was also obtained when connecting the Air's transmitter to a late-model Yamaha AV receiver and PlayStation 3 game console. However, when I tested the transmitter with power from a USB port on a Samsung Blu-ray player, a link was established with the receiver but it was unable to maintain the connection during video playback. A check of the player's USB port specification indicated that it maxed out at 5V/500mA - about half the required amperage. Switching the transmitter to a wall adapter quickly restored video output from the Blu-ray player.
Signal tests
The Air's 60GHz radio system was able to pass a usable 1080p signal through a wood framed wall at a total distance of about 11 feet, but the connection wasn't 100% reliable. The included documentation clearly discourages through-wall use, and it recommends keeping the transmitter and receiver within 10 meters of each other for best performance. With uninterrupted line-of-sight, I was able to nearly double that distance.
I found it best to mount the units high enough to minimize interference from people walking between the transmitter and receiver, but the Air's signaling proved robust enough to handle almost anything short of a completely covered unit.
Ultra low lag
Console gamers will be pleased to note that the Air3C added a miniscule 4ms of lag to a 1080p60 video stream as measured by the Leo Bodnar LagTester - a fraction of a frame of added delay with a 60Hz video source! Given the adequate USB power output of the PlayStation and its Bluetooth wireless controllers, the Air could regulate it to a nearby closet while retaining full functionality.
AV quality
For all intents and purposes, the Air's wireless video quality is identical to that of a wired HDMI connection with a maximum claimed throughput of 4Gbps. 1080p 24Hz and 60Hz signal tests from a DVDO AVLab TPG (read my review) and Blu-ray reference materials were delivered unaltered. RGB and YCbCr444 color spaces were supported although color depth beyond the common standard of 8 bits-per-pixel appeared unsupported.
Audio transport was similarly clean when listening to the Blu-ray album Sea Change from Beck that features a 24 bit/192kHz 6-channel PCM audio track with a sustained bitrate of 27.6Mbps. Obviously, the Air had no trouble handling the less data-intensive lossless soundtracks of Blu-ray movies.
Even better
I had nothing but praise for the original DVDO Air, and the Air3C-Pro adds impressive energy efficiency that enables it to be powered with a common USB port without degrading performance. The more affordable non-pro version of the Air costs about $100 less, but the pro version's software proved useful for determining optimal placement of the transmitter and receiver. No, nothing beats the reliability of a copper cable, but the DVDO Air3C-Pro is my recommended way of doing a 1080p HDMI link wirelessly.
Review: Sony FMP-X10 4K Media Player
Tuesday, October 14, 2014 at 10:13PM 
Owners of 4K ultra high-definition (UHD) televisions soon discover that the current selection of 4K movies and TV shows is pathetically limited. The Sony FMP-X10 4K Media Player delivers more 4K content than any other set top box, and a recent update frees the FMP-X10 from Sony-only TV use enabling it to work with any 4K UHD display that supports HDCP v2.2 copy protection.
Simple setup
The X10 is simple to setup and use, and it features a second audio-only HDMI output that enables it to easily integrate with HDMI AV receivers that lack support for the necessary copy protection (most).
Robert's Favorite Home Theater Gear
Conveniently, Netflix 4K streaming is built in, and Amazon 4K Instant Video will be added early 2015. Sony uses the AVC (H.264) codec for downloaded 4K movies saved to the FMP-X10's 1TB internal hard drive, and streaming 4K content is encoded with HEVC (H.265). The high bitrate of the downloaded movies I sampled made for an exceptionally detailed viewing experience - particularly with newer digital productions. The more time I spent viewing the X10's impressive high resolution imagery the more it increased my urge to upgrade to a larger TV or 4K projector to better appreciate it.
To buy or not to buy
Sony has created a terrific 4K viewing experience with the FMP-X10, but I wanted more. The X10's selection of movies and TV shows must expand with regular updates to ensure long term enjoyment. Many titles have affordable rental options, but some content is only available for purchase and prices are not exactly cheap. It's still early in the 4K UHD scene, and gear like the Sony FMP-X10 4K Media Player is helping to fill in the current content gaps - even it the price of admission is a bit steep.
Update
Sony has confirmed that its 4K movie library is encoded in lossless multichannel LPCM audio - it sounded lossless! Also, most of the 4K feature films and TV episodes available via Sony's Video Unlimited service are encoded using x.v.Color, a wider color gamut than BT.709, which "delivers deeper colors, especially reds." However, we await further details regarding the proper method of evaluating displays and video optimized for the expanded color palette the x.v.Color spec.
