OLED is the only technology capable of absolute blacks and extremely bright whites on a per-pixel basis. LCD definitely can't do that, and even the vaunted, beloved, dearly departed plasma couldn't do absolute blacks. Why can't LCD do that? It's like putting sunglasses in front of a candle.
Even the best LCDs can't completely block all the light, so in order to get those inky movie-theater-like blacks, you have to turn the backlight down the "candle" in this analogy. In the most LCDs, the entire backlight works as one, dimming the entire screen if that. Local dimming LED LCDs are far better, but still only dim and brighten relatively large "zones" of the screen independently. They're still very bright, and have better blacks for a better contrast ratio, but in a well lit room, or in direct sunlight, you'll be able to see an LCD better.
Because of that better contrast ratio, in most other situations, or in a room with curtains, TV shows and movies -- everything from standard-def to high-def to 4K with high-dynamic range -- all really pop. All TVs, to create the images you watch, use red, green, and blue mixed together to create all the colors of the rainbow well, not quite all colors, but most.
Then, using color filters, the yellow and blue light is filtered to create red, green and blue. To add a bit more brightness, there's also a clear "white" element, too. It's a lot easier if I show you:. A yellow OLED material creates yellow i. When combined with blue 1 , this creates "white" light 2. Though this seems odd and convoluted, it obviously works since LG is the only company that has successfully marketed large-screen OLED TVs in any numbers. This is because it's more cost-effective to make "more" being the key word there.
The apparent downsides, such as light output and color accuracy, don't seem to be issues. Sure, they're not as bright as the brightest LCDs, but they are still very bright, and the current models have the same color saturation as the best LCDs.
Speaking of apparent downsides, here's another: burn-in. Or at least, the potential of burn-in. Burn-in is when an area of the screen can't produce the same amount of light as the rest. It's essentially more worn out than the rest. That section might look like it has a bit of a shadow, or in extreme cases, you can make out the shape of what burned in.
For example, a shadowy after-image of a news station's channel logo might be visible when you change the channel. OLED TVs are susceptible to burn-in, but in all but the most extreme cases what you'd see is more accurately described as "image retention. Burn-in is permanent, and would only happen if, say, you only ever watch one channel for 8 hours a day every day. As long as you use your TV to watch a variety of content i. They're the same image, but we've circled the section with the logo on the right to highlight it.
To see it better, turn up your screen's brightness and look for a rectangular shape. In person, it's more visible in a dark room, but much less visible with moving images as opposed to a test pattern. All 4K TVs double the number of pixels across that of a standard HDTV, vertical scanning lines are doubled as well, from p to p — making 4K resolution effectively four times that of full HD, so you'll see the picture, not the pixels, even up close.
OLED enables a simpler internal structure than conventional displays. With just a few layers, LG OLED TVs are unbelievably lightweight and super-thin — about the thickness of a few stacked credit cards at its thinnest point. OLED TVs also have superior viewing angles, with consistent color and contrast at some of the widest angles. With their spectacular, true-to-life richness, pencil-thin profiles, super-clear action, superior viewing angles, and gorgeous, nuanced colors that virtually match those seen in movie theaters — LG OLED 4K TVs provide the ultimate entertainment experience.

This isn't a downgraded flagship TV — it's a down sized flagship TV. It offers the same performance and features as its bigger brothers in the CX range which, let's remember, also match the more expensive GX, RX and WX in terms of picture quality and processing , but in a smaller, more living room-friendly package.
The performance is superb. The perfect blacks and near-perfect viewing angles we're used to from OLED combine with bright, punchy whites and vibrant but natural colors. LG's motion processing is the best it's ever been, too, and its OLEDs continue to impress in terms of upscaling p and standard-def content. On top of all that you get certified HDMI 2.
Those last two features will be of particular appeal to those gamers looking to upgrade to the PS5 or Xbox Series X. The enclosure bolted onto the back houses the speakers, processing hardware and connections. But that's really the only fault we can find with this TV.
Sony's X1 Ultimate processor produces stunning images, there's plenty of dark detail on show, and you have access to virtually every streaming app you could hope for. Motion control is sensational, and in terms of sharpness and detail, you won't find a better TV at this size.
We've already covered the new inch version of the CX above, but it's worth remembering that the inch and inch models are also still available and the bigger you go, the better value you get.
The picture performance is just as excellent on these bigger sets, and simply more cinematic to boot, and of course the next-gen HDMI feature set and smart platform is the same, too. What's more, the bigger sets sounds a little bigger and fuller, too, thanks to the bigger chassis, although it's worth bearing in mind that the CX isn't the best-sounding TV in its class and that you're well advised to also budget for a soundbar.
It manages to improve picture quality in a few key areas, with dark detail, color richness and motion handling all getting a boost. Sound from the down-firing speakers is surprisingly good too, its built-in Dolby Atmos decoding delivering a wide and expansive soundstage by TV standards.
The GX is an attractive set and one of the best OLED TVs for wall-mounting — there's no stand in the box, but there is a slim mount on which you can hang it. Inputs, which include four HDMI 2.
Blacks are deep and packed with detail. It's even a great upscaler when faced with Full HD and standard-definition video. Sound quality is similarly impressive. The Sony uses two actuators, which actually and imperceptibly vibrate the whole screen, essentially turning the whole panel into a big, flat driver. It's clever and does a great job of tying audio and video together. But for everyone else, the A8 is an excellent all-rounder that demands consideration. Picture and sound quality are both excellent, as is the TV's motion handling.
It also boasts a fabulous upscaler for Full HD content. Where it falls down slightly is with native 4K HDR pictures.
