Helpful Hints
Welcome to the new frontier of 4K Ultra HD television, where cutting-edge technology meets immersive viewing. Offering roughly four times the resolution of Full HD, 4K brings spectacular detail to your favourite films, shows, and sporting events. In this guide, we’ll highlight the key benefits, technical specifics, and why an LG 4K TV—powered by our specialised Alpha processor—can transform entertainment in your home. Discover how 4k on a tv sets the benchmark for modern viewing and learn why an LG 4K TV might be the perfect upgrade for streaming 4k UHD content in Australia.
Traditional HD (1920 x 1080) contains around 2 million pixels. In contrast, 4K resolution (3840 x 2160 pixels) offers about 8.3 million pixels, greatly enhancing image quality. This expanded resolution implies you’ll see finer textures, sharper lines, and a greater sense of realism whether you’re viewing digital content, 4K video footage, or a wildlife documentary.
Because a 4K TV packs so many pixels into the same space, you can sit closer without noticing individual pixels. This makes 4K perfect for large screens, smaller living rooms, or for those who simply prefer a front-row viewing experience.
Studios and streaming platforms have rapidly embraced 4K UHD as a new production standard. From nature documentaries to binge-worthy series, more Ultra HD content emerges every month, ensuring your 4K TV purchase retains its value over time.
A TV’s resolution is measured by the number of horizontal pixels multiplied by the vertical lines. 4K on a TV is typically 3840 x 2160 pixels for consumer UHD screens, though digital cinema 4K is a slightly wider 4096 x 2160. In practical terms, it means you get greater image sharpness, depth, and clarity than a standard Full HD display (1920 x 1080 pixels).
By quadrupling the pixel count, 4K Quality remains crisp even up close—where an HD display might start to show pixelation.
While 4K increases the sheer number of pixels, High Dynamic Range (HDR) improves how each pixel appears. HDR expands the contrast range between bright highlights and deep blacks, making colours pop with extra vibrancy. Shadows become more nuanced, while bright areas avoid washing out.
For gamers, many consoles support both 4K and HDR, making titles look more dramatic and lifelike than ever. UHD content, richly embedded with vibrant colour and clarity, brings each scene alive.
What does UHD in 4K mean for my everyday entertainment? In its early stages, true 4K Ultra HD content was harder to find. But now, streaming services like Netflix, Prime Video, and Apple TV provide an ever-growing library of 4K shows and movies. Blockbuster films, sports events, and original series are increasingly produced with 4K Quality in mind.
With more UHD 4K channels, films, and sports coverage launching every year, you’ll stay ahead of the curve by investing in a 4K TV.
Modern 4K TVs rely on powerful processors to upscale non-4K content. LG’s Alpha processor, originally developed for our OLED range, offers pixel-level control and outstanding AI upscaling performance—making HD content appear closer to 4k quality. Thanks to advanced frame-by-frame analysis, older shows and movies can look crisper than ever.
Experience your favourite sports with incredible detail—from the grass on the field to the sweat on an athlete’s forehead. Gamers will also appreciate the higher resolution and HDR effects, bringing every environment and character to life. Overall, these features demonstrate how 4K goes beyond simple resolution—4K on a TV helps enhance the visual experience across a range of genres, from action-packed matches to atmospheric films.
LG’s 4K range caters to diverse needs—whether you want an entry-level set or a top-of-the-line OLED packed with advanced picture technologies. This wide-ranging LG lineup showcases the industry-leading capabilities of 4K Ultra HD televisions, providing an incredible viewing experience. Models include smart TV platforms, giving you quick access to Netflix, Prime Video, Apple TV, and more in 4K Quality. Find a size and feature set that fits your living space, budget, and style.
If you’ve asked yourself 'What is 4K TV?' or 'What does 4K mean?', the answer lies in remarkable clarity, immersion, and an expanding selection of 4K content. With HDR pushing the boundaries of colour and contrast, and advanced upscaling enhancing even older media, now is the perfect time to step up to an LG 4K TV. Immerse yourself in a world of detail that Full HD simply can’t match.
With enhanced 4K video and camera capabilities, the likes of Amazon and Netflix turn live events into a visual feast, offering UHD 4K for your viewing pleasure. Find out how 4K is already reshaping the TV landscape and you’ll be ready for more unmissable action. With the increase in 4K footage and broadcast quality, 4K resolution continues to set the standard in viewing options across the world.
4K upscaling is the process of improving non-4K images to edge them closer toward 4K images. A processor in the TV improves the quality of HD pictures, frame by frame, and displays them in a higher standard. LG’s Alpha processor analyses each frame, cleans up noise, and improves detail, so even if you’re not watching native 4K content, you’ll still notice a striking difference. The pictures appear sharp and clear. Even if you aren’t watching native 4K content, you’ll experience a much better picture thanks to 4K upscaling.
4K TV is not only better – it’s precisely four times better. With a screen containing four times the number of pixels, a 4K resolution display packs in more fine detail. Get up close and personal with a 4K screen and the detail stays clear and consistent.
Most OLED TVs boast 4K resolution. It’s important to point out that OLED and 4K are different technologies. OLED is a type of screen technology, whereas 4K is a screen resolution. So, you can have an OLED TV that is also 4K. When OLED screen is combined with 4K resolution, you get one of the best picture quality experiences available. For gaming enthusiasts, these televisions offer a wide range of specifications that redefine the experience.
