The LG UA73006 43″ 4K Ultra HD Smart TV is a compact LED set aimed at households that want a sharp 4K picture, easy streaming and a few gaming-friendly touches without paying premium OLED prices.
LG is well known for its TV expertise, and this model leans on that pedigree with 4K resolution, HDR support and the tried-and-tested webOS smart platform. It is very competitively priced for a 43-inch 4K set, making it attractive as a main TV in smaller living rooms or a high-quality second screen.
With a 4.8 out of 5 user rating from more than 200 reviews, it’s clearly gone down well with owners, suggesting that its real-world performance and ease of use live up to the spec sheet.
This 43-inch LG is ideal for small to medium living rooms, bedrooms or open-plan spaces where you sit a couple of metres from the screen. The 4K resolution and HDR support mean films, sport and boxsets will look much crisper than on an older HD set, even at this more compact size.
If you want a budget to mid-range TV that still feels modern, this model fits nicely. You get webOS with all the big streaming apps, Freeview Play-style catch-up and handy extras like screen mirroring and built-in music services, without paying extra for high-end panel tech.
It also suits casual and family gamers. Auto Low Latency Mode and LG’s Game Optimiser help keep input lag in check on consoles, while the 60 Hz refresh rate is perfectly adequate for most living room gaming. Serious competitive gamers might look higher up the range for 120 Hz or VRR, but for everyday play this is more than up to the job.
If you’re after an easy-to-use first 4K TV, an upgrade from an older 1080p set, or a quality secondary screen for a snug or bedroom, this LG should be on your shortlist.
The 4K Ultra HD resolution delivers a noticeably sharper, more detailed image than older Full HD TVs, especially with native 4K content. HDR support adds extra depth and punch to films and series, bringing brighter highlights and more nuanced dark scenes when the content supports it.
Filmmaker Mode is a real plus if you enjoy movies as the director intended. It dials back aggressive processing and motion smoothing automatically, so films look more natural without you having to dig through menus.
webOS remains one of the most straightforward smart TV platforms to live with. You get a wide spread of video and music apps – from Netflix, Disney+, Prime Video and Apple TV to Spotify and TIDAL – plus web browsing and HbbTV, all wrapped in a clean interface.
For gamers, Auto Low Latency Mode and the dedicated Game Optimiser settings help reduce lag and make it easy to tweak the picture for different game genres. The presence of three HDMI ports with eARC support also makes it simple to hook up a soundbar and multiple devices.
Sound is better thought-out than many budget sets, with 20W of power, 2.0-channel speakers, AI Sound Pro processing and LG Sound Sync/WOW Orchestra support if you pair it with a compatible LG soundbar.
The main compromise is the basic 60 Hz LED panel. It’s fine for everyday viewing but won’t offer the ultra-smooth motion or deep blacks of higher-end 120 Hz or OLED sets, particularly noticeable in fast-moving sport or very dark scenes.
Energy efficiency is rated G, so it’s not the most economical TV to run. While this is common for many modern 4K sets, it’s worth bearing in mind if you watch a lot of TV every day.
The warranty is just one year, which feels a little stingy given TVs are typically long-term purchases. An extended warranty might be worth considering for peace of mind.
There’s no support for advanced gaming features like Nvidia G-Sync or variable refresh rate, so keen competitive gamers may find it a little limiting for next-gen consoles.
At 43 inches, this LG strikes a sweet spot between screen size and practicality. It’s large enough for immersive viewing in most UK living rooms yet compact enough to sit comfortably on modest TV stands or in bedrooms. The flat screen design is slim, and the 300 x 300 mm VESA mount support makes wall-mounting straightforward if you prefer a cleaner look.
webOS keeps day-to-day operation simple. Once you’re connected to Wi-Fi, you can jump straight into catch-up TV, Netflix or YouTube without fuss. The inclusion of an electronic programme guide and timeshift/USB recording means live TV is easy to navigate and you can pause or record over-the-air broadcasts with a suitable USB drive.
Screen mirroring and Miracast support make it quick to share photos, videos or apps from your phone or laptop to the TV, handy for family viewing or informal presentations. Bluetooth 5.1 and Wi-Fi built in mean wireless headphones, speakers and game controllers are easy to pair.
Sound is perfectly adequate for everyday use. The 20W speakers and AI Sound Pro processing keep dialogue clear and add a bit of width to the soundstage. For films and gaming, adding a soundbar via HDMI eARC or LG Sound Sync will give you a more cinematic feel, and WOW Interface/Orchestra integration helps the TV and compatible LG soundbars work together smoothly.
The core picture setup is a 43-inch 4K Ultra HD LED panel with a 3840 x 2160 resolution. For typical viewing distances of 1.5–2.5 metres, this delivers a crisp, detailed image where Ultra HD streaming, UHD Blu-rays and next-gen consoles really shine. LG’s upscaling handles HD broadcasts and older content respectably, so non-4K sources still look clean and well-balanced.
HDR support adds extra dynamism to compatible content, improving contrast and colour. While an LED TV at this price can’t match the deep blacks of OLED, HDR still helps pick out more detail in bright skies, streetlights and shadowy scenes, provided the source supports it. Filmmaker Mode comes into its own here, knocking back over-processed motion and over-saturated colours so movies look more cinematic.
On the smart side, the TV runs WebOS with a full suite of popular apps: Netflix, Disney+, Prime Video, Apple TV, NOW, DAZN, Rakuten TV, YouTube and more, plus a wide range of music apps. HbbTV and web browsing round things off, and ThinQ integration offers LG’s smart ecosystem features, making it easier to fit into a connected home.
Gaming performance is boosted by Auto Low Latency Mode and the Game Optimiser. When you fire up a console, the TV can automatically switch into a low-lag mode, reducing the delay between your inputs and what you see on screen. The 60 Hz refresh rate is fine for most console gaming at 30 or 60 fps, though it doesn’t have premium extras like VRR.
Connectivity is strong for this class: three HDMI 2.0 ports, including eARC, two USB 2.0 ports with USB recording, digital optical audio out, Bluetooth 5.1 and Wi-Fi. That’s enough to connect a soundbar, games console, streaming box or Blu-ray player without running out of inputs, and eARC ensures you can pass high-quality audio to external sound systems.
With a current price of £229, this LG undercuts many premium 43-inch sets while still delivering genuine 4K resolution, HDR, a mature smart platform and a decent spread of connectivity. It sits comfortably in the budget to lower mid-range bracket for 4K TVs, which makes its feature set particularly appealing.
You’re not paying for headline-grabbing technologies like OLED panels or 120 Hz refresh rates, but you do get well-implemented basics: crisp 4K, a good app selection, gamer-friendly modes and sensible audio features. For most households, those are the things that matter day-to-day.
The 4.8/5 user rating from over 200 reviews strongly suggests that buyers feel they’re getting their money’s worth. The only real marks against its value proposition are the G energy rating and the short one-year warranty, but these are common trade-offs at this price point.
Overall, it offers very strong value for anyone who wants a capable, modern 4K TV without stretching the budget.
The LG UA73006 43″ 4K Ultra HD Smart TV is a well-rounded, affordable option for households wanting a sharp 4K picture and a full-fat smart TV experience in a compact size. It combines a crisp 4K LED panel, HDR support and Filmmaker Mode with webOS, strong app coverage and genuinely useful gaming features.
It’s not the last word in picture performance – you won’t get OLED-level contrast or advanced 120 Hz gaming capability – and the G energy rating plus one-year warranty are worth noting. However, at this price, those compromises are understandable and won’t be deal-breakers for most buyers.
If you’re upgrading from an older HD TV, kitting out a bedroom or looking for a sensibly priced main set for a smaller living room, this LG is an excellent choice that punches above its weight on features and user satisfaction.
