This tv doesn't have full, true HDR. HDR however allows for more vibrant colors. Ultra HD (aka 4K) is the resolution, aka pixels.
Sorry, there was a problem. Please try again later.Ultra HD is a level of resolution (how many pixels make up the image). HDR is the measured brightness range between highlights and shadows (how much detail exists in shadows and very bright items like a sunny sky). There is no comparison between the two. They are distinctly different features. Ultra HD (or UHD) is a resolution of 3,840 by 2,160. True 4K (also known as DCI 4K) is 4,096 by 2,160. HD, in comparison, is either 1920x1080 (1080i) of 1280x720 (720p). Almost no consumer-grade televisions actually use true 4K. They're almost all UHD. So, on the consumer side, UHD has sort of become 4k. On the professional side, DCI is 4k. HDR simply means High Dynamic Range. The "high" part of that is simply relative to the range older television was broadcast at (known in broadcast as REC709). HDR simply retains more detail in darker and brighter portions of the image. It also includes more variations of color. Think of a kid's drawing of a rainbow with 11 distinct and seperate colors. Now imagine what a real rainbow looks like. In reality, those colors mix at varying levels in between. In broadcast REC2020 is generally accepted as HDR. REC2020 has about 60 times the combinations of color it canaccurately display. But consumer TV's offer many variations of HDR right now. There's HDR10, DolbyVision, and HLG. That's where it gets confusing. You'll need the Google to research the differences with those.
Sorry, there was a problem. Please try again later.Ultra HD, or 4K is the resolution that the pannel can display. The vas majority of television solds until 2015, had a maximum resolution of 1200 x 1080 or 1080p, also know as Full HD. Ultra HD or 4K is 4 times the resolution, which means images with a significant amount of detail can be displayed on the screen. HDR on the other hand, is yet another new technology. It stands for "High Dynamic Range" In short, is a new technology that allows television pannels to display higher levels or brightness, and significantly more colors on the screen, compared to standard television sets. I have personally seen the difference and it is stunning. If i were to buy an ultra HD/4k TV, i would definitely go with one with HDR capabilities, even if the technology is new and there is only a a handful of content providers (like Netflix) with HDR material. It is definitely the future, and i can wait to enjoy more of it. Hope this helps.
