4K refers to the approximate number of pixels or dots that display horizontally across your display or TV screen. In reality, this number is 3,840, but TV manufacturers round up to 4000, or 4K resolution.
Most current HDTVs feature 1920 (or about "2K") of these pixels. Many next-generation TVs and displays have doubled the number of horizontal pixels as well as the number of vertical lines. In sum, this leads to a four-fold increase in the number of megapixels.
HDR (High Dynamic Range) is a new standard for Ultra HD TVs that brings image quality closer to the natural world. Your TV comes to life will richer colors, more details, and brighter objects. Filmmakers are able to maintain much more of the original image quality and deliver the look that they intended. For example, you can now enjoy the full radiance of the sun in a scene without missing details in the dark shadows.
HDR standards for TVs support twice the number of visible colors (one billion+!). Colors will appear more vibrant and true-to-life and the picture will have less noticeable gradients between shades of colors. HDR standards also support much higher brightness levels (1000 nits) and more contrast (greater than 10,000:1). Learn More about HDR.
The more pixels and colors, the clearer the image. 4K HDR delivers ultra-sharp image quality that's 4X sharper than last-generation 2K HDTVs with 2X the number of visible colors. Movies and TV shows will be more detailed than you've ever seen on a television before, and sports will make you feel like you're at the game.
The NVIDIA SHIELD Android TV box is powered by the NVIDIA® Tegra® X1 processor, which supports 4K H.265 (HEVC) and VP9 video streams at a fast 60fps refresh rate – making SHIELD fully HDMI 2.0 compliant. This is much better than, for example, the new Fire TV that supports 4K resolution at 30fps and delivers sub-optimal experiences while viewing fast action sports, movies, and video games. Plus, it delivers a wider 10-bit color range (as specified by rec. 2020) and offers High Dynamic Range (HDR) for smoother gradients and richer and brighter colors on your TV.
