LG's processor automatically detects and optimises both the picture and sound of what you're watching for a superior watching experience.

Life's about more than having the latest technology. It’s about the experiences technology creates. From TVs and refrigerators to laptops and computer monitors, LG UK delivers home electronics that let you embrace life and prepare you for its greatest moments. That’s exactly what we’ve got. Compared with its predecessor, the CX offers more dark detail, richer colours and better motion and, when added to an already exemplary performance, that makes for an astonishingly capable all-round performer. As is the norm for LG, HDR10+ isn’t supported by the CX, but standard HDR10, HLG and Dolby Vision all are. The company’s 2020 OLEDs also all support the new Dolby Vision IQ format, which tailors the Dolby Vision performance to the ambient light in the room. It’s not as transformative a feature as Dolby would have you believe but, while we were initially underwhelmed when testing the LG GX, we can now see the benefits of Dolby Vision IQ in terms of some extra detail being revealed in dark scenes when there’s a fair bit of light in the room. While Dolby Vision IQ has won us round somewhat, the same cannot be said of Filmmaker Mode, another new feature for LG’s 2020 OLEDs. This is a UHD Alliance-approved picture preset that’s supposed to deliver the picture precisely as intended, but it isn’t metadata-led or tailored to the specific content being played. In fact, here it’s just a blanket set of picture settings that’s practically identical to those of the Cinema preset, and the result is a very dull picture.Users in the US will also find Hulu and Vudu in the app selection, although Vimeo is missing, while Australian buyers get the likes of Telstra TV Box Office, Foxtel and Stan. LG’s AI Picture Pro picture system has had a deep learning performance bump this season which allows it to better optimise and analyse images in real time; it seems HD upscaling is also a beneficiary. The set’s latency performance is very good for gaming. We measured input lag at 12.6ms (1080/60) with Game mode on. LG C1 review: Sound quality Percentage luminance drop at 35 degree horizontal angle from the centre of the screen with 100% white output

If you want to connect your TV to a blu-ray player, games console, soundbar or soundbase then you'll need a HDMI cable. The C1 features LG's innovative OLED technology, with Dolby Vision IQ and Dolby Atmos sound, for a supremely cinematic experience. It's powered by the a9 Gen4 AI processor, producing an always-optimised 4K HDR picture. Use LG's award-winning webOS smart platform to stream shows from such apps as Netflix and Prime Video*, and you can interact by voice with both the Google Assistant and Alexa built in. Max light output HDR (high dynamic range) while displaying a live scene and white square taking up 10% of the screen (measured in Nits) Steveykay said:I can’t believe the LG OLED55CX does not have BBC iPlayer - possibly now the most popular BBC channels in the UK and I certainly wouldn’t buy it knowing it needs an external streamer box to receive BBC iPlayer.For me (and a lot of tv watchers) it’s irrelevant I watch 99% of my tv via Sky which has all of the Apps. Together, Dolby Vision IQ and Dolby Atmos audio ensure even more immersive entertainment, providing supreme clarity, depth and excitement.The brain of the TV is the 2020 version of LG’s Alpha 9 (a9) processor. This ‘Gen 3’ chip brings with it, among other things, a feature called AI Picture Pro, which LG says will “enhance the resolution and sharpness of contents by an algorithm learned via a LG Deep Learning technique”, and AI Sound Pro, which “provides the optimal sound or Virtual 5.1 surround, depending on the watching genre”. The key picture presets here are Standard, Vivid, and Cinema Home. All three impress. There’s also a dedicated Filmmaker Mode, regular Cinema, Eco, plus some ISF settings – Expert (Bright Room) and Expert (Dark Room). I can’t believe the LG OLED55CX does not have BBC iPlayer - possibly now the most popular BBC channels in the UK and I certainly wouldn’t buy it knowing it needs an external streamer box to receive BBC iPlayer.

LG has also clearly done some work on its motion processing for 2020, and while it’s still a touch behind Sony, the CX and its siblings do a good job of sharpening and smoothing motion without making it look unnatural. In addition to the new webOS, LG has also revised its menus, making them aesthetically a little more appealing. LG C1: Verdict The HDMIs are better specified here than on rival TVs. For starters, they’re officially HDMI 2.1 certified, and while that isn’t the guarantee of support for all next-gen HDMI features you might expect, the CX does support those likely to be of concern for the next few years, including eARC (Enhanced Audio Return Channel), HFR (High Frame Rate), ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate). Available in screen sizes from 48- up to 83-inches, the LG C1 is home to LG’s entire premium feature set (with the exception of the brand’s brighter new Evo panel technology, which is reserved for the LG G1 and G2), making it as well specced as most of the best OLED TVs. This TV has the Google Assistant and Alexa built in, so you can get answers to questions while you're watching TV, and control compatible smart home devices.

As LG makes panels for the rest of them, this panel will be offered by another manufacturer but + iPlayer and that will scoop LG's UK customers. There’s a full suite of AI modes (grouped under the AI service setting), which offer blanket processing improvements regardless. AI Picture Pro crunches video content and applies noise reduction and sharpness in real time, while AI Brightness offers an HDR-style lift to SDR programmes. Similarly, AI Sound Pro uses clever audio processing to lift and separate two channel and 5.1 mixes. The major image changes in the LG C1 compared to 2020's LG CX are in the processing, which uses a year's worth of advancement in so-called 'AI' enhancements, which enable the TV to recognise more specific types of scenes, and to make custom adjustments that make the images look as good as possible depending on what's being shown.
