LG 55UH770V review

 Review: June 2016  

Rating: 5 stars

In a nutshell: The LG 55UH770V is a UHD TV that offers true HDR10 and Dolby Vision support, which means super-sharp images, high dynamic range, and bright, natural colours. With premium design and excellent Smart TV, plus a "magic" remote it's an all-round family entertainment system, and very competitively priced too.


Design & looks

The LG UH770V is the cheapest of LG's "Super UHD" TV range for 2016. It shares the same basic design as the more expensive UH850 model, with a silver crescent base providing good support, and a matching silver bezel surrounding the screen. The chassis is deeper than in the more expensive models, but it's a good-looking TV with very contemporary styling and a definite premium feel.

55 inches is the "must-have" size for 2016 it seems, and if you have the space and the budget, it's definitely an excellent size for family viewing.

The UH770V comes with the same magic remote control as LG's top-end models, and lets you control the TV by pressing buttons, pointing the remote, using gestures, or even voice commands.

Picture quality

LG's "Super UHD" LED TVs use IPS screens in combination with local dimming, quantum dots and ColourPrime Plus technology to reach the high contrast range, peak brightness and wide colour gamut required by the Dolby Vision and HDR10 standards for High Dynamic Range (HDR). That means that it not only reads HDR information encoded in UHD Blu-ray disks, and in Netflix 4K streaming, but it can actually reproduce the colours and dynamic range of full HDR. This gives it an advantage over cheaper TVs such as the Samsung KU6400, which is HDR-capable but doesn't meet the Dolby Vision and HDR10 standards.

So much for standards. How does the TV perform in real life? We'd say that like LG's other Super UHD TVs, the UH770V offers excellent viewing performance. It's very bright, which is a key benefit for daytime viewing, and it can unquestionably reach very dark blacks. Colours are vibrant, and there's plenty of shadow detail visible. Our one complaint is that the pseudo-local dimming system is less refined in this model than in the step-up UH850V. The result is that sometimes the individual zones become visible, as the backlighting attempts to optimise the lighting of each vertical zone. Most people probably won't notice, but it's the kind of thing that can be bothersome if you do.

Motion clarity is excellent with this 200Hz panel. Even at this large 55 inch size, motion blur isn't a problem. Viewing angles are reasonably wide too, for an LED TV.

This is quite possibly the cheapest entry point into true HDR. While the picture isn't quite as polished as the UH850V, this is a genuine UHD HDR television, and is very capable. You'll experience the best results with true HDR sources, such as a UHD Blu-Ray player, but 4K streaming or 1080p Blu-ray will also produce very sharp, impressive pictures. Upscaling from DVDs or HD broadcasts begins to reveal the weakness of those formats on such a big 4K screen, and if you watch a lot of standard definition TV, you're really wasting your money buying a TV of this spec.

We should point out that there is no support for 3D viewing on this TV.

Audio quality

LG has downsized the speaker system for the UH770V compared with the UH850V/UH950V. While it still carries the Harman/Kardon label, it's a fairly standard twin speaker setup, with 20W of power output. Like with most mid-range TVs, we'd recommend a sound bar as a worthwhile addition to get the most out of it.

Smart TV

The UH770V uses LG's latest WebOS 3.0 operating system to provide a raft of Smart functionality. From the menu you can select channels, access catch-up TV and on-demand content, and install a range of apps. You can also control devices such as a Blu-Ray player or home cinema system from within the WebOS user interface.

Catch-up TV services include the BBC iPlayer and Demand 5. There's on-demand content from the LG Content store, Netflix 4K and Amazon Instant Video. You'll also find a web browser, social media, YouTube, and access to apps from the LG Store.


The 770V comes with built-in Wi-Fi and ethernet for connecting to the internet and your home network. There are 3 HDMI connections, one with ARC compatibility for connection to a soundbar. Three USB ports are provided, one of which is USB 3.0. A range of legacy AV connections are also available, including SCART, component & composite inputs, and a digital audio optical output.

The TV supports network file browsing, and Miracast wireless sharing with compatible smartphones, tablets and other devices. It also has Bluetooth support for a wireless keyboard and mouse.

You'll find both built-in Freeview HD and Freesat HD tuners here. With an optional USB disk you can even record programmes, although as the TV lacks twin tuners, you cannot watch one programme while recording another.

Conclusion - a very impressive mid-range TV

The pricing of the LG UH770V puts it at the top of mid-range, and we expect the price to fall as low as £1000 as Black Friday and Christmas draw near. This is the third and cheapest of LG's Super UHD TVs we've reviewed this year, and as you'd expect, it's the least capable. In fact, we wouldn't want to go any lower in LG's range.

Having said that, we can still find it in our hearts to award the 55UH770V 5 stars, although 4.5 is closer to the truth. For while the 770V is very good value, it's just starting to show its shortcomings, especially with the backlighting, but also with the lack of 3D and the more basic sound system.

But don't mis-read us. This is better than anything Panasonic or Sony can offer for this kind of money, which makes the only real competition the step-up LG 55UH850V, which is more expensive but perfect, and the Samsung UE55KU6400, which is cheaper, but still very highly capable.

Have you made sure in the TV settings you enabled HDMI UHD colours (might require enabling for that specific hdmi port connected to your xbox) or any similar settings perhaps game mode or HDR, and also in the settings of the xbox?

What is the "Input Lag" time in Game mode?

Have had this tv for about a month an it is absolutely stunning. My 2nd 4k tv but this is amazing in comparison. The smart features and ease of use are wonderful,the picture is at times a little blurred when playing 4k content but thats to be expected from a midrange .For 900 bucks it was a no brainer and I cant see myself changing until an oled 4k hdr drops to about the same price.
