Product Overview

LG CX 4K OLED Smart TVs feature all the latest bells and whistles but retains the classic television form factor: Its Alpha 9 Gen 3 AI Processor offers improved processing power and AI deep learning capabilities. All models feature 120Hz refresh rate and support NVIDIA G-SYNC as well as AMD FreeSync for superior gaming performance.
These standard 4K OLED smart TVs share the same technical specifications and functionalities as the more posh Gallery-Design GX Series, Wallpaper WX Series, and Rollable RX Series.

    The CX is the first OLED TV that can match LCD TVs with true 120Hz refresh rates. Like all recent OLED sets, the CX was extremely uniform in brightness and color. Gaming input lag is similar to last year, which is to say superb. Parasite is a great movie that looks spectacular in 4K HDR.

    Pros

    LG's OLEDs still produce some of the best picture quality you can buy. Sony's A8H provides some strong competition, and I expect Vizio's OLED will also give LG a run for its money. The difference among these TVs will be minor and can only be seen when viewing multiple TVs side-by-side.

    The LG CX OLED TV is more than capable of creating a single-playing experience for gamers. Its 120Hz refresh rate doesn't stack up to the ever-popular Samsung Odyssey G9 and its ability to produce 240 MHZ. Response time is still nearly instant thanks to low latency and HDR gaming is fantastic.

    Pros

    The LG 48 CX OLED is an impressive overall TV to use as a computer monitor. It's a great choice for any type of use, and it's excellent for gaming. It has a 120Hz refresh rate, native FreeSync support, and a near-instant response time. The screen doesn't get bright enough to combat glare, but it has outstanding reflection handling.

    Pros
    • 120Hz refresh rate

    The LG CX OLED is fantastic for dark room viewing because it has a near-infinite contrast ratio and perfect black uniformity. It has wide viewing angles, making it a great choice for watching TV shows and excellent for sports with a large group of people. Unfortunately, like all OLED TVs, it has the risk of burn-in, which could be a problem with constant exposure to static logos.

    Pros
    • Fantastic reflection handling
    • Wide viewing angles
    • Near-instantaneous response time
    • Low input lag

    • Can't display very bright colors

    The OLED65CX boasts two new picture modes. Filmmaker Mode is designed to recreate the settings creators use when mastering content. Dolby Vision IQ combines the extra HDR picture information and screen optimisation elements of DolbyVision with an assessment of room conditions provided by a built-in light sensor. In its Game mode it only suffers with a puny 13ms of input lag. There's support for both automatic low latency mode switching and variable refresh rates.

    LG has spent years refining its webOS smart TV software. The webOS's flexible system of tabs and easy-to-follow graphics make it one of the more accessible smart TVs on the market. The CX OLED does not have far-field microphones built-in, so you're limited to the microphone input on the remote.

    Pros

    LG's 48-inch OLED48CX is one of only a few full-sized OLED TVs on the market. The screen maintains all of the same individually small but cumulatively important enhancements. Colours are every bit as rich, vibrant, but also precise, balanced and consistent across the screen as those of the bigger CX models. Viewing angles are as typically excellent as you’d expect from OLED.

    Black levels are impressively deep, but still provide detail in the darkest parts. Contrast is superb, making for suitably rich and dramatic presentation. While it’s not the brightest OLED, it feels brighter than the C9/E9. Dolby Vision content has a rich, textured and almost creamy aspect to the picture. The input lag is not the quickest on the market, but LG offers full support for the latest gaming features.

    There's plenty of detail in the many dark scenes (the one in which K meets Dr Ana Stelline for the first time is a great example) Plenty of punch to provide that enticing, exciting contrast when we get to downtown LA. Motion is handled well – vastly better than it was by last year's LG OLEDs – but Sony still has the upper hand here, as a comparison with the KD-55A8 proves.

    Pros
    • Punchy, punchy picture
    • Dolby Atmos and Dolby Vision
    Cons
    • Bassy start to Blade Runner 2049

    LG OLED55CX has the same excellent performance as the 65GX and 48CX. Blacks are flawlessly deep, but there's more detail to them compared with last year's sets. The way the set combines excitement and realism is its greatest strength. Dolby Atmos mode creates quite a large and spacious soundstage.

    • Dolby Vision IQ
    Cons

    The LG CX puts in another brilliant performance. Few TVs upscale lower-resolution content in such a clean and convincing way. Colours are balanced, edges are sharp and there's none of the added picture noise that you get from some rival TVs. All versions of the CX get the same 2.2-channel, 40W sound system. By the standards of the class, the sound is punchy and dynamic, too.

    Pros

    • Dolby Atmos and HDR10+ support
    • Excellent sound
    Cons
    • No BT Sport app
    • No Dolby Vision

    OLED TVs aren't “normal” LED-backlit TVs. Instead, each pixel is filled with an organic material that's able to act as its own backlight. Super bright reds, greens, and blues juxtapose themselves alongside insanely realistic shadows. The CX is one model where it might be worthwhile to buy a 4K Blu-ray player.

    Pros
    • Extremely low latency
    • Fantastic picture quality
    • Great for gaming
    Cons
    • No built-in speakers
