A Review of the LG Electronics UF7700 4K Smart LED TV (2015 Model) – 60UF7700, 65UF7700, 70UF7700, 79UF7700

by on September 24, 2015

The LG 65UF7700 is one of LG’s 2015 4K TVs which isn’t one of the company’s now legendary OLED ultra HD TV models and as such it seems to suffer from the same problems that often plaque other non-OLED 4K offerings from this otherwise capable company. Basically, while the 65UF7700 delivers decent picture quality and some solid features, there are more than a few things with which to find fault in this model and that’s annoying.

We know for sure that LG can absolutely deliver superb results when it wants to in its 4K TVs. We’ve seen this with the company’s entire 4K OLED line and their 65EG9600 65 inch model in particular has widely been claimed as the best 4K ultra HD TV of the entire year so far. This is why it’s all the most frustrating to see LG delivers subpar results for its non-OLED models, its 2015 LED/LCD 4K UHD TVs in so many little ways.

Again, the 65UF7700 is not at all a bad set and some of its key features are really something to behold in this model but problems with less than perfect black levels, overall color quality and 4K video rendering are something we’ve seen in other LG TVs that come without the golden goodies of OLED technology.

The Good

What we like about the 65UF7700 includes a few physical design features, it’s connectivity options and more than a few of its visual display specs along with the sound quality on this 4K TV.

For starters, the 65UF7700 is relatively well priced at just below $2,000. While there are cheaper and probably better Samsung SUHD TVs on the market and at least a few solid 2015 Sony 4K TVs as well for the same or a lower price, the 65UF7700 is nonetheless a decent buy given its screen size and set of newer 4K smart TV technologies. While the TV doesn’t come with some of LG’s cutting-edge technologies like the awesome Harmon Kardon speakers we’ve seen in some of the company’s premium OLED TVs, and a virtually bezel-free design, it does include a great package of connectivity ports, an excellent TruMotion 240Hz simulated refresh rate and comes with the benefit of the really user-friendly LG Magic Remote.

Furthermore, while not up to par with the razor sharp clarity of Harmon Kardon sound such as that found in LG’s OLED 4K TVs, the built-in audio of the 65UF7700 is still nothing to laugh at and offers one of the better home entertainment sound experiences we’ve seen in a 2015 4K TV.

Finally, the color rendering in the 65UF7700 is generally very crisp and realistic enough to be considered good while the IPS panel technology ensure both a high level of vibrant brightness to the colors and also some excellent side angle viewing quality, with low loss of contrast and vibrancy even at sharper off-center angles.

The bad

The 65UF7700 drops the ball on more than a few issues and this is something that really annoys us about LG. Unlike Sony and Samsung, to name just a couple of examples, LG seems to coast along on its brand recognition and really not put some of its better engineering into its lower-end 4K UHD TVs. It’s as if the company is so absorbed in the pushing of their OLED 4K TVs that they simple lost interest in the staple technology of LED/LCD.

For starters, the quality of dark tones in the 65UF7700 is just bad. Dark tones are too saturated with light and sometimes even a bit of light bleed-induced clouding appears in certain parts of the screen. For a company that is capable of delivering the technology which creates the perfect, absolute black of their OLED TVs’ you’d think LG could manage decent contrast in an LED TV like this, but they apparently don’t.

Furthermore, the Tru 4K Upscaler engine on the 65UF7700 is not as good as many we’ve seen. This is an area in which Sony X850C, Samsung JU6700, and even Panasonic really do a fine job while this model only delivers middling results. While Full HD content upscales decently on the 65UF7700, 720p HD and 480p videos sometimes scale up with some blur and more than a few processing artifacts can be seen in the resulting picture.

This deficiency of the 65UF7700 is particularly problematic due to the fact that a lot of people who own a 4K UHD TV depend on the quality of its upscaling engine for getting value from the display in a market where native 4K UHD content is still somewhat hard to find, especially in homes without the minimum of 25Mbps in broadband internet necessary for streaming native 4K from Netflix or Amazon.

Final Thoughts

As far as we’re concerned, the LG 65UF7700 is a decent TV with a decent size and some solid connectivity and visual features. However, for the retail price at which this model is selling, you’re better off going with one of the more economical Samsung SUHD TVs, one of Samsung’s even more affordable JU 4K TV models or one of Sony’s more budget-oriented 2015 UHD models. All of these offer better value, better access to apps and definitively superior picture quality and contrast at similar prices.

The first and foremost highlight of the LG 65UF7700 is without a doubt its superb Smart TV platform. We’re of course talking about the excellent WebOS 2.0 that the 65UF7700 comes with, just like its much more expensive cousins the OLED 4K TVs from LG.

WebOS 2.0 is definitely one of the best smart TV systems on the market today and even if this TV is lacking in other regards, the platform does a lot to alleviate their deficiencies. Boot times in the WebOS system are much faster than in previous LG smart platforms and better than the boot times in many other smart TV systems, including even Samsung’s excellent Tizen platform. Furthermore, the interface layout of WebOS 2.0 is a very simple, very intuitive system that makes sorting and later looking for favorite programs and apps really easy through either voice controls or the point and click controls of the LG Magic Remote.

Furthermore, the main Smart TV options on the 65UF7700 are broad and excellent as sources of 4K UHD and HD content. These include Netflix, Amazon, YouTube (for 4K UHD videos) and an assortment of others like HSN, Showtime, Drama Fever iHeart Radio and Hulu for HD content. You can also access DirecTV’s streaming movie app (only for Full HD content in an LG TV for now) and the GoPro video app, to which you can upload your own 4K or HD GoPro videos (if you have a GoPro Hero camera) or watch some of the at times spectacular videos uploaded by others.

The core feature of WebOS 2.0 is its simplicity and in this spirit, LG has foregone a home screen in favor of a bright multicolored strip of buttons along the bottom of the 65UF7700’s screen. Seeing all downloaded apps, switching between apps and loading content you’ve been viewing are all done nearly instantly with the flick of a button thanks to the efficiency of WebOS and the power of the 65UF7700’s quad core processor.

Finally, the sound quality on this TV deserves mention as one of its highlights. LG didn’t include the beautifully sharp audio of Harmon Kardon speakers in the 65UF7700 but the built in 20W 2 channel speakers with ULTRA surround are nonetheless powerful and deliver some wonderfully clear audio power. In fact, we’d go as far as to say that the sound quality on this model is better than that of just about most 4K TVs on sale now at the same price point. Only Sony really delivers superior audio at the same general price range.

Visual Specs

Visuals is where the biggest weakness of the 65UF7700 really lie and in this regard the TV really drops the ball at times while delivering results that are wither so-so or only good in other respects.

First of all, the quality of the 65UF7700’s contrast is simply low. This TV suffers from too much light in its dark tones and is thus light years away from the contrast offered by Samsung’s SUHD TVs or even Sony’s better but still reasonably priced 2015 Bravia 4K models. We won’t even go into detail on how shameful the contrast created by this poor dark tone saturation is when compared to the exquisite blacks and bright tones in LG’s OLED 4K TVs. True, this isn’t an OLED TV and thus such a comparison isn’t entirely valid but when we look at how wll LG can deliver the visual goods in its best 4K TVs, we wonder why the same company can’t at least match its biggest rivals’ LED/LCD TVs when it comes to non-OLED display technology. Overall, the contrast between the dimmest part of the screen sits at around 0.128 cd/m2 while white level brightness sits at 101 cd/m2. This is indeed a weak contrast level that underperforms even what you’d find on many lower priced 4K UHD PC monitors.

Secondly, the upscaling engine on the 65UF7700 is only moderately good at dealing with Full HD content and even with this type of resolution, it delivers a softer, weaker level of upscaling clarity than what we’ve seen with most Sony, Panasonic and Samsung TVs of a similar caliber in 2015 and 2014. When it comes to upscaling 720p, 480p and DVD video content, the Treu 4K Upscaler of the 65UF7700 performs at a downright subpar level with lots of blurriness and sometimes even the appearance of processing artifacts on the screen. This is a particular shame in a 4K TV given how vital high quality upscaling of lower resolutions is in a market where native 4K content is in the drastic minority.

Finally, as far as color rendering goes on the 65UF7700, what you get is not too bad at all at least, with some very decent at the 2.16 range and an overall realism and vibrancy of colors that’s pretty good after some manual calibration away from the out-of-the-box settings of the 65UF7700. However, even here, LG’s Color Prime technology, which uses colored phosphor coating on the TV’s LEDs to “enhance” colors, doesn’t perform nearly as well as similar phosphor-based Triluminos Display technology in Sony’s 2015 4K TV models.

On the other hand, one of the definite strengths of the 65UF7700 is the IPS display technology is uses in its screen. With IPS, off center viewing still manages to look clear enough for decent viewing and contrast degrades by only 20% or so even at sharp off-center angles. There are better TVs for off-center viewing on the market but the 65UF7700 stands above non-IPS 4K models we’ve seen.


As far as connectivity goes, the 65UF7700 from LG delivers a solid level of performance that’s as good as what you’ll find in its premium LG 4K TV cousins and only slightly inferior to the connectivity of most competitor 4K TVs, mainly due to the fact that this model only comes with three HDMI 2.0 ports instead of the more usual four.
On the other hand, the full package of USB 3.0, USB 2.0 and other major connectivity options is fully present and accounted for in the 65UF7700 and all HDMI ports come with full HEVC and VP9 video compression decoding capacity, as well as full HDCP 2.2 content copy protection compliance. We’ve already covered the apps and web connectivity options of the WebOS 2.0 smart TV platform but we’ll basically state again that they are also about as robust as is the standard in the 4K TV market right now.


The LG 65UF7700 65 inch 4K UHD smart TV is currently retailing on Amazon.com for $1,797.99. This isn’t a terrible price for a 4K TV of this size but the lower than expected quality of this model’s visual specs reduces the value of buying this model at this price by quite a bit.

Not so Great

To rehash the less than great aspects of the 65UF7700 quickly. Its absolute biggest weaknesses lie in the overall quality of its display specs. While color rendering is decent, contrast and the TVs content upscaling engine are subpar. Furthermore, the 65UF7700 could use one more HDMI port.


• Excellent WebOS 2.0 smart platform
• Very decent color rendering
• Great LG Magic Remote functionality
• Solid connectivity features


• Contrast is low quality
• Full HD, HD and SD/DVD upscaling is not great
• Some problems with light bleed
• Color could be still better

Bottom Line

After weighing in on all of its assorted specs and deficiencies, we can’t fully recommend the 65UF7700 as one of your best choices for a 4K home entertainment system. While this model has some solid aspects going for it in terms of connectivity and its excellent WebOS 2.0 smart TV platform, the deficiencies of its display specs (especially in terms of upscaling quality and contrast levels) leave much to be desired.

    We bought one f the 60″ UF7700 sets and were literally repulsed at the poor quality of the color reproduction, the light imbalance of the panel and the poor depth of blacks. Very disappointing, and this experience will make me reconsider another purchase with the LG label on it. They just don’t seem to care about anything but their OLED product, which is nice but could be simply outstanding.
    We ended up with a Sony panle and it is simply superb compared to LG or Samsung LCDs. What Sony has accomplished with the richness of colors (realism) and depth of blacks on an LCD is astounding, and it was LESS money. FOr those who care streaming on the Sony is also just blazing fast.

      Hello Jack. Yes, an unfortunate characteristic of almost all 2015 LG 4K TVs has been their mediocre and in some cases downright terrible contrast and black performance, in some cases also color reproduction. Their main saving grace is the high quality webOS 2.0 smart TV platform in these TVs but as far as display quality goes, we almost always recommend either going for LG OLED or if you want an LCD TV, sticking to superior producers of these models like Sony and Samsung, or even Vizio! We have hopes for the 2016 LCD lineup of LG 4K models and strongly hope the company has put more effort into making them good instead of simply focusing on their admittedly spectacular OLED models. We’re currently working on LG LCD 2016 4K TV model reviews and will soon have a firm opinion on them.

    There were some good price cuts on the 49″ UF770, was tempted to get one.
    But looking all the negatives comment I backed out. Didn’t even consider o test it out in the store.

    Decided to go with the 2016 model, chose the UH650.
    Couldn’t find any reviews thus far about this model, but I’m quite please witht the display. But one thing that really bothers me is the input lag. Didn’t affect much while switching to full screen, but when used the multi-display feature of WebOS, it was down right horrible.
