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

by on July 8, 2015

Introduced to the market in 2015 by LG, the UF7700 is one of LG’s more affordable 4K UHD TVs. While still pricey by some standards, this wonderfully sized

79 inch TV offers full ultra HD 4K resolution on a beautifully giant IPS panel display that delivers wide viewing angles and excellent contrast and color thanks to LED Plus local dimming technology.

While the UF7700 isn’t one of LG’s very famous OLED 4K TVs (if it were it would cost much more than it does at this size), it still provides decent overall picture quality, full connectivity with the latest features and full 4K content compatibility. On top of these specs, you can also count on the highly rated LG webOS smart TV platform, a powerful quad-core processor to make everything on that platform and on the screen run smoothly and a full internet connectivity package with web browsing and complete access to thousands of online apps.

On the whole, the 79UF7700 may not be one of LG’s best 2015 4K models but it nonetheless offers typical LG quality in one superbly gigantic 4K home entertainment package. Also, make sure to check out the LG OLED EG9600 Review which is a comparable model.

The Good

To briefly summarize the key pros of this model here:

The LG UF7700 offers excellent detail at 4K resolutions and does a particularly wonderful job with streaming 4K content from online so 4K display, it looks particularly good on larger screens and few TVs offer a bigger display than the 79UF7700 with its massive 79 inch screen.

Furthermore, for all that non-4K content you’re also going to be watching on this machine, the LG Tru-4K Upscaler engine is a remarkably good example of this technology in how well it scales up 720p and 1080p HD content. Blu-ray HD looks particularly fantastic when scaled up on this model (it looks better even than much native 4K content from a streaming source like Netflix) while even 480p SD content gets a decent effort put into its own upscaling, though the final result with this last resolution can look a little blurry on the large 79 inch display.

Moving beyond display features, the UF7700 also comes with an excellent set of built-in speakers, a highly precise and versatile Magic Remote that offers great range and an intuitive user interface to go with that remote. In fact, the webOS 2.0 of this and all other 2015 4K TVs is nothing less than stellar and possibly one of the best smart TV platforms on the market right now.

Finally, the giant screen belies the elegantly minimalist design of the UF7700. Its screen is wonderfully thin and perfect for mounting to a wall through a VESA apparatus.

The bad

On the other hand, nothing comes perfect, not even with LG TVs and the 60UF7700 is definitely not on the same shelf level as LG’s much more expensive flagship OLED 4K TVs for 2015. Thus, the black levels on this otherwise very decent display are not ideal and for those of you who’ve seen OLED in action, the contrast and black rendering on this TV will look downright second-class in comparison.

Furthermore, there is the issue of motion blur. While certainly not a deal-breaker, it does definitely become notable if the UF7700 gets used for fast-action 4K gaming or during some high-speed movie and sportscast sequences.

Finally, the overall picture quality of the UF7700 is definitely not on par with that of the company’s flagship TVs. This model reflects its price but in a less than ideal way due to problems like low contrast, input lag and color vibrancy. This is unfortunate because competitors like Samsung also offer more budget oriented 4K models for 2015 but still manage to include most of the high-end visual specs of their flagship TVs while still charging a better price than that found in the UF7700 or its smaller 60 inch TV cousins.

Final Thoughts

The LG 65UF7700 is definitely not LG's finest effort among the company's 2015 4K UHD TVs. While this model offers great connectivity and smart TV features, the key feature of the model, its display, suffers from a number of deficiencies. To add insult to injury, LG is selling the TV for just under $5,000. If you want a big screen with excellent display quality, you're better off with something like Sharp's Sharp LC70UH30U. It costs $2400 less, comes with an also excellent 70 inch screen and offers better visual specs.

We should start a description of the 65UF7700’s highlights with a mention of its webOS 2.0 smart TV interface. This has been praised by us before and the overall consensus among many reviewers of LG’s 2015 4K TVs is that the upgraded smart TV platform for this years is excellent. It offers an intuitive, easy to use interface, easy navigation and a neat apps and browsing menu along the bottom of the home screen. Furthermore, things are made easier still thanks to the 65UF7700’s Magic Remote and voice recognition navigation feature. LG got this right on all of its TVs, OLED or not.

Secondly, the one display feature of the 65UF7700 that really sticks out in terms of quality is the IPS display with its excellent viewing angles. While the 65UF7700 isn’t exactly the most advanced LG 4K model in terms of contrast, color and motion rendering, it definitely delivers on low fade at off-angle viewing.

Third, the Tru-4K upscaler is remarkably good on this model, as we’d already mentioned above, the 65UF7700 does a remarkably good job of turning HD and Full HD content into something closer to 4K level video and even manages to make SD content look relatively decent, which is no mean feat considering that its taking 480p resolution and scaling it to fit onto a native 2160p screen.

Finally, the connectivity options on the LG 60UF7700 are as good as you’ll get with even the best of the company’s 2015 4K models, with full HDMI 2.0 connectivity, HDCP 2.2 compatibility and full HEVC and VP9 decoding capacity. Internet connectivity is also there thanks to an Ethernet port and built-in WiFi.

Visual Specs

Visual specs are unfortunately where the LG 60UF7700 suffers somewhat. Don’t’ get us wrong, this 4K model still delivers good to decent picture quality, fantastic 4K upscaling and a wonderfully massive screen size but in terms of color, contrast and overall brightness, it suffers somewhat.

First of all, peak contrast in a darkened room is not ideal, sitting at about 850:1 with divergence of just under 99.8 cd/m2 between black and white areas on the screen. This worsens even further under bright room viewing conditions with glare being applied to the screen.

Things also don’t do so well when it comes to both black and grey uniformity, with inverted detrimental effects notable for each: black uniformity is uneven, with brightness leaking through along the edge of the screen and grey uniformity looks somewhat dirty with darker edges than the tone of the screen interior.

Finally, while the 60UF7700 offers a local dimming feature to augment contrast, the fact that it’s an edge-lit 4K TV and has only very large “local” dimming zones reduces the effectiveness of the dimming considerably.

Thus, while the 60UF7700 does offer some great upscaling technology, it really underperforms on contrast, uniformity and even color. This isn’t a terribly 4K display by any means and the IPS panels work wonderfully to improve viewing angles but the UF7700 certainly doesn’t come even close to what LG’s 4K OLED models deliver.


As we’d already mentioned, the connectivity package on the 70UF7700 from LG is perfectly fine and pretty much on par with that of any other 2015 LG 4K TV. You get all the essentials here in the form of three HDMI 2.0 ports, three USB ports and full HDCP 2.2 copy protection capacity built into the HDMI. There’s also built-in WiFi, Ethernet and the wonderfully robust webOS 2.0 with its full browser package and access to numerous streaming video and 4K video apps like YouTube, Netflix and Amazon Prime Instant Video.

Furthermore, thanks to the HDMI 2.0 ports with HDCP, the LG 70UF7700 can take 4K video at 60Hz from external, third party ultra HD set-top boxes and media players.

In basic terms, this is definitely a fully equipped 4K TV for ultra HD content access.


The price of the LG UF7700 is less than ideal considering the display deficiencies of this model. Yes, you’re getting your hands on a superbly large screen but the quality of video it’s going to deliver doesn’t quite match that of much more affordable 60 and 70 inch models from Samsung’s SUHD line of TVs such as the JS8500 or the JS7000. You can also take a look at the non OLED/SUHD such as Samsung JU7500, JU7100 or the Sony X850C Review. The 60-inch 60UF7700 is currently retailing for $1,497.99 on Amazon.com. The 65-inch 65UF7700 is retailing for $1,797.99, the 70-inch 70UF7700 for $2,4997.99 and the 79-inch for $4,497.99.

Not so Great

To briefly summarize, while the LG 70UF7700 comes with excellent smart TV features, excellent viewing angles and great connectivity, its display specs leave quite a bit to be desired for the high price you’re going to pay for this model. LG is charging more for its brand name and raw screen size than for pure quality with this 4K TV model.


• Excellent screen size
• Superb webOS smart TV platform
• Good viewing angles thanks to IPS display technology
• Solid connectivity and 4K content access


• Poor contrast ratio
• Not the best color reproduction
• Middling picture quality overall
• Somewhat expensive

Bottom Line

The bottom line for the 79UF7700 is that you’re getting a somewhat overpriced 4K TV which doesn’t deliver as well as it could on a number of visual specs. LG is charging extra money more due to raw screen size and its own brand name than for any particular quality specs.
