Overview

The LG UF6800 is a 4K ULTRA HD TV with a sophisticated 4K up-scaler built in. The TV produces some beautifully vibrant, rich and crisp images and has a HEVC decoder that delivers pin sharp and blur-less motion at a truly impressive 60 FPS. It’s ultra slim and super light; it’s only 1.38 inches / 3.5 cm thick and weighs a tiny 18 Kg (with stand).

The TV does have some drawbacks however. Firstly, there is occasionally some juddering at 60 fps. Secondly, the contrast ratio, although good, could be slightly better for a TV in this price range. Thirdly, motion blur and input lag, although both satisfactory, could be better. And fourthly, the sound is good, but could be quite a bit louder.

The Good

The LG UF6800 features a sophisticated 4K up-scaler built in. What the up-scaler does is dramatically improves the sharpness and richness of non 4K content, bringing it as close as possible to the look of 4K. The TV features an IPS panel with Tru-Color Generator and Tru-Black Control.

The TV also comes with a HEVC decoder that delivers pin sharp and blur-less motion at a truly impressive 60 FPS. This allow you to view even wirelessly streamed content with a level of quality that really is unachievable with TV’s that operate at a much lower frame rate, as many do. The frame is one of the biggest stand out features of this TV.
The TV is ultra slim. It is only 1.38 inches / 3.5 cm thick and weighs a tiny 18 Kg (with stand). This means the TV doesn’t occupy huge amounts of space in your living room, and will look less out of place, even in smaller houses/apartments.

The TV is completely flat which means it doesn’t suffer from some of the prominent issues that curved TV’s suffer from such as dime edges. The TV provides a noticeably wider viewing angle and images look crisp, sharp and colourful from all angles. This is partly thanks to the IPS panel which results in the image not looking washed out and blurry at angles as many LED panels do.
The LG 55UF6800 doesn’t skimp on sound. It features “Ultra Surround”, a proprietary two channel speaker system. The TV has 6 sound modes (Standard, News, Music, Cinema, Sport, Game), additionally it has 3 sound optimiser modes (Off, Stand Type, Wall-mounted Type).

The TV also features the latest version 2.0 of the WebOS operating system. This provides a clean, uncluttered layout and intuitive and easy to understand menus so you can gain access to the TV’s countless features effortlessly. The operating system really has a big effect on how much the average user gets out of a TV of this calibre. What’s even better is that the LG 55UF6800 comes with something called “launcher. Launcher allows you to navigate through various apps and settings whilst still staying on your current screen. This makes things even more intuitive and means you can navigate without fear of losing sight of what you are currently doing.

The LG 55UF6800 also has “Smart Share”. Now you can wirelessly send your music, photos and video files from your laptop, PC or smartphone straight to the TV with a click of a button. And when you combine this feature with the intuitive and excellently designed WebOS 2.0 you get the recipe for a truly superior and effortless viewing experience. Now you can view all of your content from any decide on the LG 55UF6800’s superb screen, and best of all, you can do it without being shackled by cords and without having to frustratedely navigate through a maze of menus and settings. Brilliant.

Time for a little more magic. The TV comes with an optional “LG Magic Remote” which has been made to work specifically LG 55UF6800 and a handful of other TV sets. So what does it do? Well, it offers you a multitude of ways of communicating with your TV. You can command your TV by pointing, scrolling, via voice…or you can use the good old buttons if you are old school sort of person. The remote is also universal so works with a number of other devices. Although you have to buy the remote separately, as LG 55UF6800 is one of the TV’s the remote has been made to work especially well with, we highly recommend it.

The bad

There are some negatives about this TV, which we will explore below.

Firstly, you may experience some juddering if playing footage at 60 fps, especially as the TV’s judder-free mode only goes up to 24 fps.

Secondly, the contrast ratio for the TV is satisfactory but not great, especially when compared to it’s big brother the LG UF7600 or TV’s from other brands such as the Samsung UN55JS7000 that are within a similar price range.

Thirdly, both the motion blur and input lag are just satisfactory and could be a bit better for a TV in this price, however, it must be noted that the vast majority of viewers will likely not detect any issues and it is hard core gamers that will most likely pick up on the mediocre motion blur and input lag of this TV. Further, on the topic of gaming, the TV doesn’t support gaming at 120 fps.

Fourthly, if you place this TV in a room with a lot of lights present then that could be an issue, as the TV reflects far too much and when exposed to a lot of light a yellow tint is present, which isn’t pleasant at all.

Fifthly, although the sound is impressive from a TV this thin and light, there are some issues that have to be mentioned. The most critical thing about the sound is that it doesn’t go that loud however that can be easily addressed by hooking it up to an external sound bar or a surround sound system. Additionally, some pumping may also be present if trying to push the sound to the limits with the TV’s built in speakers.

Sixthly, as mentioned earlier, from a technical perspective, the TV is not really a true 4K screen. As there are some white pixels, the TV is not (RGB, RGB, RGB, RGB) but more (RGB, WRG, BWR, GBW).

Final Thoughts

The LG 55UF6800 is a 4K ULTRA HD TV produces some truly stunning pictures. And when you’re playing content that’s not 4K (which at this point will be most content) the TV’s 4K upscaler works it’s magic and makes it look dramatically crisper, clear and more vibrant. The TV is flat so doesn’t suffer from the issues that curved TV’s do, and is ultra slim and super light.

The TV does have some drawbacks. There are some juddering at 60 fps, the contrast ratio leaves a little to be desired, the motion blur and input lag are so so, the sound could be louder, and the TV is not technically true 4K.

Highlights

IPS On A Flat Display - The TV has a stunning IPS display which is ultra slim (just 1.38 inches) and beautifully flat which also means it doesn’t suffer the same drawbacks of the curved displays on the market. The flat form factor coupled with the IPS technology means that images don’t look murky or washed out when viewed from side angles unlike many similar TVs in it’s class.

4K Upscaler - The TV also has a 4K up-scaler built which enables you to view non 4K content with extra clarity, depth and realism. It’s one of the major stand out features of this TV and is especially great as there isn’t that much true 4K content on the market at this moment.

Up to 60 FPS – The TV comes with a HEVC decoder able to achieve a truly impressive 60 FPS. At this frame rate you will notice significant improvements. Motion is crisp and flawless and everything is much sharper and more dynamic.

Ultra Surround - The LG 65UF6800 includes LG’s proprietary two channel speaker system. The TV has 6 sound modes which include; Standard, News, Music, Cinema, Sport, Game).
WebOS 2.0 - The TV also features the latest version 2.0 of the WebOS. WebOS 2.0 provides the user with a clean, uncluttered layout along with intuitive and easy to understand menus, so you can gain access to the TV’s countless features effortlessly and stress free.

Smart Share – With Smart Share you can wirelessly send your music, photos and video files from your laptop, PC or smartphone straight to the TV with a single click. Viewing all your media on this TV’s glorious IPS display really is quite something, it breathes life into everything from professional video to family photos.

Visual Specs

The LG 55UF6800 features a 55 inch IPS 4K panel with LG’s proprietary Tru-4K Engine behind the image performance, which is helped further by “Tru-Black Control” to achieve deeper, richer blacks and an improved contrast ratio.

The TV also features a 4K up-scaler which dramatically improves the crispness, sharpness and detail of non-4k content and is one the big highlights of this TV and one of its most advertised features.
The LG 65UF6800 has a Triple XD Engine, Active Noise Reduction, Dynamic Scanning, Contents Optimizer, Dynamic Clear White and Dynamic Colour Enhancer. All of these image improvement technologies help to enable the TV to achieve a superior image when compared to other IPS screens in its class.

The TV features 9 pictures modes (Vivid, Photo, Standard, Eco, Cinema, Game, Sport, isf Expert1, isf Expect2) as well as 8 aspect ratio modes (16:9, Just scan, Original, Full Wide, 4:3, 14:9, Cinema Zoom 1, Zoom). This means you can get the screen to behave in a manner that suits you and in a way that provides you with a viewing experience you find most attractive and suitable to your needs.
One of the biggest highlights when it comes to the visual specifications is the TV’s ability to play up to 60 frames per second, this provides phenomenally crisp, clean motion and really is quite impressive for a TV in this price range. However it must be noted that when playing video at 60fps there is no “judder free” mode as there is when playing video at 24 fps, so at higher frames per second you may experience some juddering. But it’s also important to note that juddering is common amongst almost all TV’s outputting video at this high frame per second rate.

Further, the contrast ratio of the TV is “712 : 1” which is good, but not as good as it’s bigger brother the LG UF7600. The default colour calibration is also not the best with this TV, however with some tweaking you can get it to a level you would be satisfied with. This is something that only true TV buffs will notice though, the majority of even heavy TV users will likely find no issue with the colour calibration settings that come as standard.

The TV has a motion blur response time of 19.9ms, which is about average for a TV of this kind in this price range. This response time means the TV is ideal for sports, but less so for hard core gaming. Relatedly is the topic of input lag. Input Lag on this TV is generally very good at 60.0 ms (when in game mode).

Our biggest gripe when it comes to the visual specs of the TV is that it is not technically actually a proper “full” 4K TV. How could this be I hear you ask? Well, it’s primarily due to the fact that some of its pixels are white. So essentially, (RGB, RGB, RGB, RGB) becomes (RGB, WRG, BWR, GBW). However, it’s really worth noting that to many viewers the difference will be negligible and they won’t be able to tell the difference, but for AV fanatics and TV aficionados they may notice a slight lack in clarity, depth and crispness especially if the TV is lined up against one that is true 4K.

Connectivity

The TV has 3 x HDMI slots (rear), 1 x LAN1 (rear), 1 x USB 3.0/2.0 (side), 1 x Optical (rear), 1 x RF in (Antenna/Cable (Rear), 1 Component Video In (Rear), 1 x Composite In (AV)

Pricing

The 55 inch version - 55UF6800 is currently retailing on Amazon for $897.99 while the 65 inch version - 65UF6800 for $1,397.99. If you have a little more to spend, we recommend you check out the Samsung UN55JS8500 or the Sony XBR55X850C.

Not so Great

Although the TV has many benefits, there are unfortunately some drawbacks. These were covered in detail above, however we felt it would be useful to just run through them quickly again here.

There are a few issues with the 65UF6800. Firstly, there is some slight juddering at 60 fps – this would be most noticeable to gamers. Secondly, the contrast ratio leaves a little to be desired. Thirdly, the motion blur and input lag although satisfactory, are not great. Thirdly, the sound is pretty good for a TV this thin and light, but it doesn’t go very loud thus an external surround system or sound bar is probably a good idea. Fourthly, the TV is not technically true 4K. Fifth and finally, the TV reflects a lot of light, so if you are going to be placing it under a lot of spotlights or in a room that gets a lot of light then you may slightly disappointed.

It’s useful to note that the above issues will not effect everyone and none are critical issues. For example, if you are someone who watches most of their content with the blinds/curtains drawn then the fact that the TV reflects a lot of light will not be an issue for you, similarly, if you are someone who does not play footage with a lot of motion or a heavy gamer then the slight juddering at 60 fps will again not be an issue. So it’s worth bearing in mind your viewing habits and the environment the TV will be in when reading the negatives about the TV.

Positives

Thin (1.38 inches ) and light (18Kg with stand)
4K upscaler built in
HEVC decoder delivers blur-less visuals at 60 fps
WebOS 2.0 operating system
Smart Share for wireless media sharing

Negatives

Some juddering at 60 fps
Average contrast ratio
Average motion blur and input lag
Reflects a lot of light
Poor sound quality
Technically not true 4K resolution

Bottom Line
 

The LG UF6800 is a 4K ULTRA HD TV with a sophisticated 4K up-scaler built in. The TV produces some gorgeous, vibrant images and the built in HEVC decoder delivers pin sharp and blur-less motion at a truly impressive 60 FPS. The LG 55UF6800 is ultra slim (1.38 inches) and super light (18 Kg – with stand) so delivers a lot in such as small package.

The TV does have some drawbacks, as covered extensively above. Firstly, there is occasionally some juddering at 60 fps (gamers beware). Secondly, the contrast ratio, although good, could be a bit better. Thirdly, motion blur and input lag, although both satisfactory, aren’t great. Fourthly, the sound is good, but could be quite a bit louder. Fifth and finally, the TV is not technically true 4K. Sixth and finally, the TV does reflect a lot of light.

We believe that although the TV does have its downsides they won’t effect everyone depending on your viewing habits and the environment the TV will be in. Further, we believe the benefits and strengths of the TV do outweigh the negative issues.

    Hello, please, did you test a decoding of UHD satellite channel? By technical information this TV can decode HEVC and has DVB-S2, so it should work, but I need some practical test/information. And what about series UF6400, can decode UHD satellite channels? Thanks a lot and have a nice day :).

    I can’t take anything on this site seriously after you repeated over and over… and over (so it’s not a typo) that the tv weighs only 18 grams — including the stand! A cupcake weighs more than that. The tv’s weight is 18KG.

      Thanks for pointing this out Pedro. The error has been corrected. Unusual to be sure that they repeated it often but the other writer clearly meant 18 kg. This was obviously not a misunderstanding of the TV’s weight but a simple formatting error.

      Hey there Spence, it should handle 4K HDR gaming decently enough in terms of graphic support but I don’t believe this model allows for HDR gaming in its game mode setting, meaning that you’ll likely deal with a high input lag.
