When it comes to motion performance, handling of 50Hz interlaced video (for example, the type of video used for Freeview or Freesat broadcasts) is still found wanting on the LG 55C7, and we noted rare but reproducible interlace artefacts such as combing in fast-action sports. For the best experience, it’s worthwhile sending a progressive video signal to the TV wherever possible.

The OLED55C7 serves up pictures every bit as fantastic as those of LG’s more expensive 2017 OLED TVs - and is even remarkably close to the 2018 models - but at a much cheaper price. We calibrated our LG OLED55C7V-ZA review sample using a Klein K10-A colorimeter profiled against a JETI Spectraval 1511 reference-grade spectroradiometer, DVDO AVLab TPG and Murideo Fresco Six-G signal generators, as well as Portrait Displays’ CalMAN software. For instance, despite not having any visible speakers, the OLED55C7 supports Dolby Atmos. This only works with Atmos carried by Dolby Digital containers, though, not the Dolby True HD containers used on Blu-rays and Ultra HD Blu-rays (which greatly limits its usefulness) but it’s still of value for the hardcore audio enthusiasts among us.While the likes of the Sony A1 have to wait for Dolby Vision to be added at a later date via firmware, LG’s 2017 OLED range has it out of the box, so it’s obviously this that you’ll want to try first. Essentially, all of those Netflix Originals that appear in standard HDR to most tellies will be streamed in Dolby Vision to the C7.

Approach this as you would any other flatscreen speaker system, though, and you’ll be pleasantly surprised. The downward-firing drivers result in a sound that’s not particularly direct and that doesn’t project into the room all that well, but that is spacious, clear and relatively dynamic by TV standards. But the C7 also has the same problem as the B7. That problem is the Sony A1, which builds on the raw materials provided by LG (the Sony KD-55A1 uses an LG OLED panel) with software that makes it even punchier and insightful. Even a small amount of de-judder and de-blur can occasionally add artefacts to fast, complex motion, and the best way to know what works for you is to experiment with the modes.The pixel pitch shows the distance from the centers of two neighboring pixels. In displays, which have a native resolution (the TFT ones, for example), the pixel pitch depends on the resolution and the size of the screen.

Approximate width of the display. If the manufacturer does not provide such information, the width is calculated from the diagonal and the aspect ratio. The default picture preset is Eco, which doesn’t deliver the best picture for viewing in the home. Turn this off. So if the C7 is the same as the B7, it gets the same score – a full five stars. Which of the two you choose should come down to which you think looks prettier, and where you prefer to shop.

A stunning picture at an affordable price puts OLED back on top

Bean Bird doesn’t cover everything, though, and while the LG generally does a good job of selecting picture settings that suit whatever you’re watching, there are a number of options you can tweak to get the best out of it. Before you write off the LG C7 based on this one photo though, we need to stress that most HDR sequences looked fine – nay, excellent – on the television. It’s only in a handful of scenes that rival sets manifested more precise detailing. Benchmark Test Results Dead pixels Audio quality of the OLED55C7V is above average by flat-panel TV standards. Dialogue is clear, and there’s sufficient dynamic range to satisfy day-to-day viewing. However, for enjoyment of movies, a separate soundbar or home theatre system is still better. While the television can decode Dolby Atmos, it currently doesn’t work on Dolby TrueHD streams from 4K Blu-rays.

Like the OLED55B7, the C7 gets the most basic audio system of all of the 2017 LG OLED range, but that’s still a 2.2 speaker system carrying the Dolby Atmos logo. The storage humidity shows the lower and upper humidity limit, which ensures safe storage of the display. Storing it outside these limits might damage the display. The operating humidity shows the acceptable level of humidity, in which the display will function flawlessly. It sets a lower and an upper humidity level for safe operation and is measured in percentage.

LG's OLED55C7V is vanishingly different to its B7V stablemate, but the picture performance is just as perfect

Finally, the OLED55C7 proves a treat for gamers thanks to taking just 21ms to render its pictures, and delivers more impact from good quality native 4K sources than any previous OLED generation. This latter strength is mostly down, it seems, to LG’s improved color subtlety and light controls in the image’s darkest and brightest areas. HDR Performance TL;DR: The extra brightness LG has found for its OLED TVs this year has a transformative effect on the OLED55C7’s stellar HDR and 4K picture quality. Sound Honestly, on this evidence there’s not a huge difference between ‘normal’ HDR and Dolby Vision, but you can rest easy knowing that when the Dolby Vision logo appears you’re seeing precisely the picture that the director intended. Update 04/24/2017: Turning on PC mode on any of the picture modes will result in input lag of about 21ms. 1080p outside game mode has been corrected after being re-tested. In terms of HDR, the LG OLED55C7V – like the rest of the company’s 2017 OLEDs – supports the open-standard HDR10, broadcast standard HLG ( Hybrid Log-Gamma), proprietary Dolby Vision and fledging Technicolor formats. While the first three are available directly out of the box, the last will be added through a software update in the near future.
