LG beats out Samsung with first industry-certified 8K Ultra HD TV

  LG beats out Samsung with first industry-certified 8K Ultra HD TV The Real 8K range of TVs from LG will be the first to receive the official '8K Ultra HD' certification from the CTA, landing 2020.Specifically, this means that LG is the first to be using the “8K Ultra HD” logo (below) and definition set in place by the Consumer Technology Association (CTA), starting with the company’s line of “Real 8K TVs” being unveiled at CES 2020.

8 K resolution refers to an image or display resolution with a width of approximately 8000 pixels. 8 K UHD (7680 × 4320) is the highest resolution defined in the Rec. 2020 (UHDTV) standard.

The display resolution or display modes of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed.

What is 8K resolution? With more TV brands than ever looking to the futuristic ultra-high definition technology for today's premium television sets, it's likely you're hearing the word '8K' thrown around more and more – but when it comes to understanding what exactly 8K means for video, home cinema, and you, the answer isn't that straightforward.

2019 was when 8K really got going, with the LG 8K OLED and LG SM99 taking up shelf-space alongside the Samsung Q950R QLED – which got a nifty 55-inch size later in the year – Sony Z9G, and TCL’s new X-Series TV.

There are enough of them now we needed a best 8K TV guide just to sift through them, and there are only more on the way – with multiple announcements at CES 2020 of new 8K models, promising advances in processing and ramped-up manufacturing in order to offer sharper and more affordable (but still pretty expensive) sets.

  Samsung's first Odyssey gaming monitors include a 240Hz ultra-wide Samsung is now applying its Odyssey gaming badge to monitors, and it's marking the occasion with two displays that are clearly geared to enthusiasts. The 49-inch CTG9 (above) is billed as the first 5,120 x 1,440 ultra-wide display with a 240Hz refresh rate and a 1ms pixel response time. You won't have to choose between extra-smooth performance and expansive, high-res visuals. It's also one of the first Samsung screens with a 1000R curvature, and it can handle DisplayHDR 1000 brightness as well as AMD FreeSync and NVIDIA G-Sync. It should show up in the second quarter of the year.If that strikes you as overkill, there will be less extravagant options.

  • Best TVs of CES 2020: the good, the weird, and the outright impressive

You can expect to hear more from the 8K Association – a community of TV makers that include Samsung Electronics, Panasonic, Hisense, TCL, and AU Optronics. It was set up to guide the visual standard of the future, and has introduced a new 8K standard to ensure consumers know they're getting minimum specs suited to the high-resolution panel (even if LG goes by slightly different measurements).

Other TV-tangential companies such as Tencent, Xperi, Intel, and Chili have also joined the 8K Association, showing an expanded desire by technological organizations to invest in (and shape) the development of the advanced panel resolution.

As manufacturers, broadcasters, and production studios are starting to get behind the new technology, it's crucial to know what you can expect to see on your televisions in the coming years, and the 8K technology that's actually on offer now.

Graham circulating resolution urging Pelosi to send over impeachment articles

  Graham circulating resolution urging Pelosi to send over impeachment articles Sen. Lindsey Graham (R-S.C.) is circulating a resolution urging House Speaker Nancy Pelosi (D-Calif.) to send over the articles of impeachment. Graham said that he passed out his resolution during Senate Republicans' closed-door caucus lunch on Tuesday, and hoped that most of the caucus would support it. "I've got a resolution urging her to send over the articles, and what she's doing is out of step with past precedent and an affront to the Senate," Graham told reporters after the lunch. "It's not her job to set the trial."He added that urging her to send over the articles would "get a lot of Republican support. Hopefully we don't have to do it.

8 K resolution has arrived. While the ultra - high resolution felt unnecessary only a couple of years ago, the push for commercial 8 K TVs from today's biggest manufacturers is starting to cement the technology's place If you just wanted a quick and simple definition, move onto the next section.

The resolution of 3840 × 2160 is the dominant 4 K resolution used in the consumer media and Televisions capable of displaying UHD resolutions are seen by consumer electronics companies as the next Ultra - high -definition television (UHDTV) – various standards for high - resolution television.

  • Samsung and friends will recommend these specs for your 8K TVs

What is 8K resolution?

8K is nothing short of the clearest picture you’re ever likely to see. It’s got four times more pixels than 4K images, measuring 7680x4320 pixels, which equates to a total of 33,177,600 pixels.

In a 65-inch screen they are so small you won't even be able to make out the pixel structure – though many 8K TVs are much, much larger.

Why is it called 8K?

It’s called 8K because the images are roughly 8,000 pixels wide, give or take a few hundred, but the specification also comes under the umbrella term Ultra HD, so some people use the term Ultra HD 8K. Others still call it 8K Super Hi-Vision, such as NHK – Japan's largest public broadcaster – which invented it back in the year 2000 and branded it in 2012.

Senators introduce resolution warning Congress has not authorized Iran war

  Senators introduce resolution warning Congress has not authorized Iran war Senators introduced a resolution on Wednesday stressing that neither a 2001 or 2002 authorization for the use of military force (AUMF) covers a potential war with Iran. The resolution, spearheaded by Sens. Jeff Merkley (D-Ore.) and Rand Paul (R-Ky.), comes after days of escalating tensions between Washington and Tehran in the wake of a U.S. airstrike that killed Qassem Soleimani."The American people do not want another endless war in the Middle East-yet what we've seen in recent days is a president willing to make significant military decisions bringing us closer to war without consulting Congress or recognizing that our Constitution gives war making power to Congress, no

8 K resolution or 8 K UHD is the current highest ultra high definition television (UHDTV) resolution in digital television and digital cinematography. High - resolution displays such as 8 K allow the user to have each pixel be indistinguishable to the human eye from an acceptable distance to the screen.

But for those who are enticed by the ultra -sharp video resolution that 8 K promises, the growth of 8 K televisions in the market is resulting in some truly But the solutions are steadily improving, and if you’re mainly interested in high - resolution content and market-leading processing, an 8 K TV could

Do all those extra pixels matter?

Absolutely, yes. Full HD 1080p TVs gave you a two-megapixel image, which isn’t much compared even to what your smartphone’s camera is capable of. 4K ups that to eight megapixels, which still seems underwhelming considering the capabilities of human vision and, again, what smartphone screens can now achieve.

So the 33-megapixel image of 8K – the next mathematical step-up from 4K – could at last provide the kind of immersion we’ve been searching for. Or, at least, that’s the theory.

  • Do we really need 8K TVs yet?

Are 8K TVs already on sale?

Yes, and you've been able to do so for a little while now already.

We've come a long way from the proof of concept 8K TVs we've been seeing at conferences for the past few years. When we first saw the 98ZHQ2R TV from Chang Hong back in 2017, the 98-inch set appeared to be held in place by something akin to scaffolding, so thick were the supports.

But that's all changed now – the latest wave of 8K TVs are every bit as thin and home-friendly as what we now expect from our existing 4K TV models.

Are there different kinds of 8K?

LG has released a range of 8K TVs a year after they were first announced (we'll cover those later), but the interesting thing is LG claims competitors don't offer the same experience as LG's real 8K.

So what's this argument about "real 8K"? Well, LG is citing the Information Display Measurements Standard (IDMS) for pixel differentiation, arguing that 8K TVs shouldn't just be defined by the number of pixels they have (7,680 x 4,320), but also how well the TV panel can distinguish / contrast between those pixels. If those tiny self-emissive dots start to merge the brightness or colors of their output, then there's little point in having so many.

LG claims its new 8K TVs achieve this Contrast Modulation (CM) "in the 90 percent range", leading to what it calls "real 8K". (The IDMS standard only requires 25 percent for images, or 50 percent for text.)

These claims came only a day after the 8K Association, an organization for encouraging the adoption and development of 8K, with members including Samsung, Panasonic, Hisense, and TCL – though notably not LG – set out its own standard for 8K TVs. Its mainly sensible stuff, such as HDMI 2.1 ports, high enough frame rates, 8K resolution, and a minimum 600 nits peak brightness, but no mention of the Contrast Modulation measurement used by LG.

UHD stands for Ultra High Definition (or Ultra HD, for shorter) and is a type of display resolution that has 3840 x 2160 pixels. This resolution is also commonly referred to as 4 K resolution . Resolution explains how many pixels a display has in length x width format (the more, the better when choosing

" Resolution " is technically the number of pixels per unit of area, rather than the total number of pixels. Since the beginning, the resolution has been described (accurately or not) by the number of When high -definition TVs became the norm, manufacturers developed a shorthand to explain

So what mainstream 8K TVs are on the market?

The Samsung Q900R 8K TV released in late 2018, and garnered a whopping five stars from the TechRadar team – albeit with a similarly whopping price tag. In the UK you were paying £4,999 for the 65-inch model or £6,999 for the 75-inch – while the 85-inch model is retailing for £14,999 / $14,999. A new 55-inch model was announced in late 2019 as well.

The 88-inch LG 8K OLED and 75-inch LG Nano Cell 8K LED TV have rolled out in the US, UK, Australia, France, and Germany too – making use of LG's a9 Gen 2 processor, with four HDMI 2.1 ports (unlike the port-poor Sony Z9G). So even OLED TVs are getting in on the action.

  • Best 8K TV: what're the very best 8K sets you can buy?

It's also worth checking out TCL's range, including the TCL Mini LED TV with 8K and AI learning, as well as this TCL’s new X-Series TV that has an 8K resolution, uses AI learning, has a retractable camera and supports augmented reality content. Yep, you read that right. It also has a ‘duo-display design’ that ‘allows viewers to enjoy a mini-screen independently’.

2020 is set to add a lot of new models, though, with LG promising three 8K sets this year (including the new Z Series OLED) and Samsung matching that amount with the Q950TS and two others.

There'll be more to reckon with down the line, and we'll be sure to update this page as new sets hit the market.

Does an 8K TV need HDMI 2.1?

Yes – and they all will have the new specification of the HDMI cable, which for the first time allows 8K resolutions to pass through. HDMI 2.1 is a major enabler of the forthcoming 8K resolution revolution, making sure TVs accept 8K resolutions at 60 frames per second (or 4K resolution at 120 frames per second).

Samsung's Galaxy S20 Ultra might have more RAM than your PC

  Samsung's Galaxy S20 Ultra might have more RAM than your PC Rumors for the Galaxy S20 have mentioned a no-holds-barred Ultra model, but just what would that entail? Quite a lot, if you believe the rumors. XDA's Max Weinbach (who shared the leaked photos of the S20+ 5G) claims the Ultra 5G will have extreme specs, including as much as 16GB of RAM in its top spec -- yes, there's a real chance this phone will have more RAM than many computers released in the past few years. It's undoubtedly overkill forThe camera setup might be just as ridiculous. Samsung's vaunted 108-megapixel camera would be the centerpiece, but also just he start. You'd also get a 48MP secondary camera with 10X optical zoom and a 12-megapixel ultra-wide cam.

Ultra - high -definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes 4K UHD and 8 K UHD

Currently, 16 K resolutions can be run on Multi-monitor setups with AMD Eyefinity or NVIDIA Surround.[2][3]Sony have recently been working on a Crystal LED display Ultra - high -definition television (UHDTV) – digital video formats with resolutions of 4K (3840×2160) and 8 K (7680×4320).

Where will 8K content come from?

There are many sources that will produce 8K content. The first is Hollywood, whose directors have begun to use the new RED Weapon 8K camera (Guardians of the Galaxy Vol. 2 has already been filmed this way in 8K).

And with the advent of truly commercial 8K TVs, there's sure to be a growing market of 8K content from all sorts of traditional TV production studios (and likely Netflix).

Second is the Tokyo Olympics, which means waiting until 2020. However, 8K will only be broadcast by NHK in Japan itself.

Coinciding with the IFA 2019 technology expo, Samsung has partnered with a number of streaming services across Europe – including CHILI, MEGAGOGO, and The Explorers – to start displaying 8K HDR10+ content.

Lastly – and perhaps most tellingly – 8K content will come from all of us. 8K capture from 360-degree video cameras is already offered by the GoPro Omni VR and Insta360 Pro, which was launched at CES 2017.

"Talk to the VR guys and they're tell you that the higher the resolution and frames rates, the better," says Jeff Park, Director of Marketing at HDMI Licensing, whose new HDMI 2.1 permits 8K image transfer. "VR today looks good but it lacks fidelity … if it was affordable and practical, they would do 8K now," he says. 8K-per-eye VR headsets, anybody? They're surely in the pipeline alongside a wider field of view.

But, in the interim, it'll be advanced upscaling processors that will take full HD and 4K content and make them ready for the 8K big time, redefining the sharpness possible from existing sources.

8K TVs aren't likely to feel like necessary purchases for a while yet, but there's already enough content on the horizon for us to expect a bright future for the high-def technology.

Leak: Samsung’s most expensive Galaxy S20 model will have insane specs .
The Galaxy S20 launch is only a few weeks away, which means that Galaxy S20 rumors are only going to get worse. Just the other day, we saw the Galaxy S20 in the wild for the first time, the Plus version, and learned plenty of specs for two of the three models, including the affordable S20 and the S20 Plus. All the time, I told you that some of the Galaxy S20 Ultra’s specs are still secret. Yes, the three phones will share the same base hardware, which includes the Snapdragon 865 chip or its Exynos equivalent, and 12GB of RAM. Separately, I also told you that the world’s first phone with 16GB of RAM might be coming this year, and it’s not going to be a Galaxy S20.
