These are called “UHD Premium” and “Dolby Vision”.

The ultimate result of this increased pixel breakdown is a an image clarity that goes well beyond conventional 1080 pixel HD resolution and presents more vibrant, varied and realistic colors as well as much higher frame rates.Currently, the most widely known type of UHD technology is the 4K resolution TV and many of these have been emerging on the market since mid-2013, although 4K display has to consist of at least 3,840 pixels (horizontal) x 2,160 pixels (vertical) of resolution and the horizontal can go above 4,000 pixels.
How is that not logical?!?! !JHC, Plenty of UHD monitors and also 4K TVs exist which come with a 16:9 aspect ratio and a 4K UHD resolution of 3830 x 2160 pixels.

Or perhaps it’s my Time-Warner broadband. Tv LED Panasonic TX-55FX550E 4K HDR – TX-55FX550E | DartyDescription. Superb ; One could appreciate the Hue of Colors in their fineness . ©

However, 3840 x 2160 (Still not actual 4K) is called Ultra HD (Which you mention elsewhere in your article) because it is 4 x Full HD (1080p).I think the correct term, rather than “4k,” should follow the standard format of 3840 x 2160, as established by the parameters of HDMI 2.0 & Displayport 1.2 — which is 3840 x 2160 Progressive (lines) @ 60 Hz. Many 2015 ultra HD television models have also been updated with firmware for HDMI 2.0a.So the bottom line for HDMI is: buy a TV, monitor or projector that’s already been outfitted with HDMI 2.0 and if possible HDMI 2.0a and you’ll be perfectly fine for the next generation of 4K content ad well as existing sources.This is one of the key questions around the question of buying into 4K TVs and projectors.

In cinema, the width stays constant, and differing aspect ratios are accommodated by adding black padding to fill the 2K or 4K container. Lean how it compares to other common display resolutions.

Almost all 4K Blu-ray discs have wide color gamut. By comparison HD screen displays vary their refresh rate to match the incoming source video. Research.“We’ve changed our advertising dimension, why is this acceptable?

We were measuring the height of the screen, but 4k is talking width. ?Thanks for posting your article, very interesting to read about the technical aspects of 4K and UHD!Last week we bought a Samsung 4K UHD television and after reading your article I now understand more about what I really bought and what is producing this impressive quality. Your entire article is biased towards the purchase of new equipment. New York, 4K in 16 by 9 aspect ratio is 4096×2304 not 4096×2160 and certainly not as Stephan Jukic states 3840×2160!!!!!!! What does 4K / UHD mean? So all our nice 50Hz video gets interpolated to 60Hz video. Perhaps part of the let-down is due to my “senior” eyes or to the extra distance (5-6 feet) away from the new screen.

Thus, while we already have 4K TVs that can create essentially “perfect” darkness with no notable light emission, in the form of OLED technology, the brightest consumer HDR 4K televisions, even for 2016, can only manage something between 1000 and 2000 nits of brightness, when in the real world, even the sky on a sunny day is seen by our eyes at about 20,000 nits.

I use an antenna for local channels and watch mostly Netflix. Quad HD is 720p x 4 which is 2560 x 1440, or 1440p. If I watch a 1080p movie on 1080p TV (Or 4K movie on 4K TV), on my computer that has a 720p display, so is it run as 1080p (Or 4K) or just as 720p?Sorry, but you are wrong on one thing on your chart: 3840 x 2160 is *not* quad HD. The Digital Cinema Initiatives (DCI), a group of motion picture studios that creates standards for digital cinema, defines 4K resolution as Get instant access to breaking news, in-depth reviews and helpful tips.Thank you for signing up to Tom's Hardware. This is what one HDR standard bearer called Doby Vision is aiming for. How is that not the correct term?!?! To all who read this, do not make a purchase based off of only this article.

This is often referred to as QHD. Since “1080p” or “Full HD” was based on the same standard of 1920 x 1080 Progressive (lines) @ 60 Hz.
4K, also known as 2160p and UHD, is a popular display resolution. Unfortunately this is still a common standard on many 2013 4K TVs but that’s changing and the latest TV models as well as the latest 4K projectors and computer monitors will all be outfitted with HDMI 2.0 ports, which are designed to handle the much higher frame rates and bit depths of UHD content. Seems more logical that 4K means 4000, as in if you rounded 3840 up, or rounded 4096 down.
