We might need to play with some words on this one, but to cut the chase, 4K and Ultra HD are referring to the same specification of a television.
However, technically, they are two different terms.
Ultra High Definition or UHD refers to a resolution of 3,840 x 2,160 pixels.
What is the difference between 4k and HDR?
In a word: No. While the higher resolution of a 4K Ultra HD TV gives you more pixels, an HDR TV can do more with those pixels. In the right hands, high dynamic range can provide a higher level of contrast between light and dark images on the screen to create a much more realistic image.
Is Ultra HD the same as HDR?
HDR and 4K Ultra HD
HDR should not be confused with the other big TV buzzword of the era: UHD (Ultra High Definition), also known as 4K. Both HDR and UHD are meant to improve your viewing experience, but they are hugely different technologies with almost no overlap. It’s a matter of quantity and quality.
What is a UHD TV with HDR?
High dynamic range, or HDR, is the latest TV feature—but not all sets do it well. You’re going to be hearing a lot about “smart” TVs capable of streaming Netflix shows on their own. And 4K—aka Ultra High Definition, or UHD—sets with four times as many pixels as regular HDTVs.
Is Netflix HDR also 4k?
Netflix 4K content has been available to stream for years now, with season two of the streaming site’s flagship series House of Cards streaming in Ultra HD 4K as early as 2014. Of course, never content to rest on its laurels, Netflix has also begun rolling out High Dynamic Range, or HDR, content.
