Optimised for the best response with movies, gaming and Smart TV, the LG OLED55CS6LA is a top performer with all content. LG ThinQ is here to help you get the most out of your TV. Choose your preferred voice assistant and use your voice to control your TV with an all-new home screen that offers more convenience and control. AI Picture Pro and AI Sound Pro harness artificial intelligence to stunning effect. AI Picture Pro uses deep-learning algorithms to recognise content, remove noise and optimise the picture. AI Sound Pro leans from more than 17 million audio data points, identifying voices, effects and frequencies. From here, it optimises the sound by genre, giving a more natural sound quality.

Speaking of which, the response times in the dedicated Game Optimiser mode are exceptional. I measured an input lag of 12ms on a 60Hz signal (both 1080p and 4K HDR), and this halved to an insanely fast 6ms on a 120Hz signal. This year LG has added a Prevent Input Delay (Input Lag) setting that can boost the response for 60Hz content, reducing the delay to below 10ms. While the LG G1, Sony A90J and Panasonic JZ1500 can go that little bit brighter [...], in isolation the C1 gets very close to that level at a lower entry point.. LG: “The G1 OLED display was designed to be used with a new panel and optimised processing within the Alpha 9 Gen 4 Processor. The C1 was designed around a different panel but is capable of using panels from multiple LGD display factories. The C1 also uses an Alpha 9 Gen 4 processor but it optimises its signal to the panel differently to insure consistent C1 performance across the line.The newly revamped home screen provides personalised content recommendations, easier access to favourites, and centralised control of linked devices. The C1 runs the latest version of LG’s webOS smart platform, and supports HDR10, Dolby Vision and HLG – but not HDR10+. All the major content streaming platforms are present and correct, including Freeview Play, which was absent on LG’s TVs last year.

Sports Alert sends you notifications prior to, during, and after games. You'll never have to worry about missing any of your favourite teams' big plays, even if you're watching something else.Confusingly, there are three versions of the LG C1 in the UK: the C16LA reviewed here, the C14LB and the C15LA. The latter is exclusive to Currys PC World, while the remaining two will be split between all the other retailers. The C14LB has a dark grey rear panel, with the other two using white, but otherwise, all three TVs are identical in terms of specifications, picture quality and features. The Rec.709 results took a little bit more care to balance out the errors we had without using too much processing power within the corrections. If you push the Colour Management System on any LG too hard, you can get lovely looking graphs, but major posterisation errors and artefacts with actual viewing material onscreen. So some care is required when making adjustments. However, we did manage to get a very accurate looking gamut result with most points at 75% and below where they should be and DeltaE errors well under three, which means there are no visible errors seen. HDR Results When it comes to picture quality, OLED easily outperforms LED. This is due to OLED's millions of self-lit pixels, which allow for infinite contrast, 100 percent colour integrity, and pixel-perfect details. As a result, you'll have a watching experience unlike any other. There is a new motion setting in the TruMotion menu called Cinematic Movement, which replaces Cinema Clear from last year. The purpose of this setting is to add interpolation smoothing in such a way that there is no obvious Soap Opera Effect (SOE), for those who don’t like or see 24fps judder. It aims to create a judder-free image by prioritising as many real frames as possible and blending these with created frames to improve the motion smoothness. I am susceptible to seeing interpolation at any strength, so it is not a setting I could live with day-to-day, but many users will like the smoothing without SOE or motion looking overly processed. With TruMotion switched off I also didn’t notice any frame skipping issues present with 50Hz broadcast material, even those programmes with fast-moving cuts looked smooth with no obvious issues. With the other settings which use more smoothing and SOE, there are obvious artefacts when motion gets fast, with edges breaking up or trailing behind fast-moving objects.

We are reviewing the 65-inch version of the LG C1, but the general performance should be the same for the other screen sizes. The LG C1 boasts a surprisingly effective sound system considering its slimline chassis. Hidden inside is a 2.2-channel sound system with 40W of power, and thanks to the sloped stand the audio from the downward-firing speakers is redirected towards the listener, creating a decent front soundstage that has width and a degree of stereo separation.For ultimate detail, in all environments, this LG OLED features Dolby Vision IQ. Dolby Vision IQ version uses data within the signal and light sensors inside the TV to adjust the picture quality for the best contrast. This improves the picture’s brightness, without ‘washing out’ the depth. You get a consistent picture quality, however light or dark your room is. Whether you’re watching a brightly lit sports event or moody movie, Dolby Vision IQ adjusts to suit. It's never been easier to stream. LG's webOS smart platform has all of your favourite apps, including Freeview Play, NOW TV, Netflix, Prime Video, Disney+, and more. The design of the C1 hasn’t changed much at all from previous generations and has the same stand designs and chassis layout, but this year there are slight colour changes. The stand on our review model was a silver finish with a white rear to the panel that LG calls Vanilla. If you want a dark coloured rear then it is called Meteor Titan. A new remote control was also introduced this year along with new menu designs and a new look WebOS 6.0 smart system which you will either love or hate, more on that later. The LG OLED55C1 is a superb gaming TV with excellent contrast and dynamic range mixed with very good HDR. The C1 is compatible with VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode) and has an HGiG (HDR Gaming Interest Group) setting under the Dynamic Tone Mapping sub-menu in the Game Optimiser mode. There is also support for G-Sync validated by NVIDIA and on top of that, there is support for AMD’s FreeSync VRR.
