Operations, THX Ltd., &amp; Jon Cielo, Director of AV Technologies, THX Ltd.<\/em>\n\n<a href=\"https:\/\/medium.com\/@thxltd\/shopping-for-a-new-tv-don-t-freak-out-let-s-talk-about-what-matters-cee6ea009ccb#.68ugw23gk\">If you\u2019re considering buying a new TV<\/a>, or \u201cdisplay,\u201d as we refer to them, you\u2019ll notice a lot of them are touting a 4K Ultra HD screen. But what exactly is 4K Ultra HD? Do you really need it? We\u2019ve got you covered on the basics to help you navigate your TV search.\n\n<strong>Defining 4K<\/strong>\nFor one thing, 4K offers finer detail. While 4,000 sounds like a lot of anything, what does that number really mean when it comes to display?\nThe \u201c4K\u201d in a 4K Ultra High-Definition (Ultra HD) display refers to the resolution. A 4K Ultra HD display features a pixel resolution of 3840 x 2160. These displays have four times the resolution of a High-Definition (HD) display, which has a pixel resolution of 1920 x 1080. Sounds like a lot, huh?\n\n<strong>Let\u2019s talk more about resolution.<\/strong>\nResolution is the ability of a display (TV) to create fine lines and curves. In the digital world, dots of color are created with squares called pixels. Trying to draw a circle with squares means you either need to have a huge circle or tiny squares to make the curves appear\u200a\u2014\u200aor resolve\u200a\u2014\u200ainto smooth lines. The fewer pixels, the more jagged a curve will appear\u200a\u2014\u200ajust like the jagged edges of the Donkey Kong 8-bit arcade game.\n\n<div id=\"attachment_608\" style=\"width: 448px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-608\" class=\"size-full wp-image-608\" src=\"http:\/\/www.thx.com\/assets\/uploads\/2017\/01\/mario.jpeg\" alt=\"\" width=\"438\" height=\"265\" srcset=\"https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/mario.jpeg 438w, https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/mario-300x182.jpeg 300w\" sizes=\"(max-width: 438px) 100vw, 438px\" \/><p id=\"caption-attachment-608\" class=\"wp-caption-text\">Mario doesn\u2019t trip despite all those jagged edges.<\/p><\/div>\n\nExamine the letter \u201cO\u201d in this sentence\u200a\u2014\u200aor in your own writing document. If you get close to the screen, you\u2019ll notice that the curves are actually steps or jagged edges created by rows of squares. When you are at a normal reading distance, you\u2019re far enough away from the screen so the steps appear smaller and therefore smoother. But if you increase the font size to 48 pts, it will look like a smooth circle, with very minor jaggedness at the top and bottom. The scaled \u201cO\u201d is larger on your screen, so more pixels are being used to render the curves. (Likewise, an extreme close-up in a movie won\u2019t make the resolution any more noticeable. The image is being magnified\u200a\u2014\u200anot the pixels that render it.)\n<em>In short, resolution relies on the size of pixels relative to the image they are rendering.<\/em>\n\nIf you want great resolution you need more, smaller pixels. That\u2019s where 4K Ultra HD displays come in, showing you much more pixels in the same amount of space. But do you get four times the quality for all those pixels?\n\n<strong>Viewing Distance Matters<\/strong>\nAnother key aspect to resolution is viewing distance. Pixel size \u201cshrinks,\u201d or is scaled down, the further away we are from an image. Just like with an eye chart, you\u2019re only going to be able to make out the shape of letters up to a certain distance away before they become blobs. So, we need a sweet spot that gives us the best resolution at a comfortable distance.\nRight now, that sweet spot seems to be somewhere between 2K and 4K resolution when the viewing distance is small. For example, Apple went with 2560 x 1600 for its first generation Macbook Retina display, which has clean, smooth lines while viewed from within two feet. In this case, when you start pushing resolution above 4K, you are creating resolution that won\u2019t be seen by the human eye.\n\n<div id=\"attachment_609\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-609\" class=\"size-full wp-image-609\" src=\"http:\/\/www.thx.com\/assets\/uploads\/2017\/01\/1-sDBBA22Mp2Jpw46CikyHtA.jpeg\" alt=\"\" width=\"800\" height=\"436\" srcset=\"https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-sDBBA22Mp2Jpw46CikyHtA.jpeg 800w, https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-sDBBA22Mp2Jpw46CikyHtA-300x164.jpeg 300w, https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-sDBBA22Mp2Jpw46CikyHtA-768x419.jpeg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><p id=\"caption-attachment-609\" class=\"wp-caption-text\">Georges Seurat\u2019s \u201cLa Parade (1889)\u201d (detail left)<\/p><\/div>\n\n<em>Pointillism purposely enlarged the dots of color to emphasize the artist\u2019s hand and demonstrate the eye\u2019s ability to blend colors and identify shapes. Displays and printers exploit this human ability to create a spectrum of colors with only a few base colors like cyan, magenta, yellow and black.<\/em>\nThere\u2019s only so much resolution our eyes can see at a distance. If you are sitting 10 feet from a 55\u201d TV, your eyes won\u2019t be able to make out a difference between an HD display and a 4K Ultra HD display. The closer you sit to your display, if it\u2019s large enough, the higher the likelihood you may realize and appreciate the increased resolution. So what\u2019s the sweet spot for your living room display? Check out the graphic below.\n\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-610\" src=\"http:\/\/www.thx.com\/assets\/uploads\/2017\/01\/1-ghF7Unj-vk60wyKUiVy4EQ.jpeg\" alt=\"\" width=\"1000\" height=\"745\" srcset=\"https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-ghF7Unj-vk60wyKUiVy4EQ.jpeg 1000w, https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-ghF7Unj-vk60wyKUiVy4EQ-300x224.jpeg 300w, https:\/\/www.thx.com\/wp-content\/uploads\/2017\/01\/1-ghF7Unj-vk60wyKUiVy4EQ-768x572.jpeg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/>How does this compare to where you sit in your living room? It\u2019s likely much closer, and I bet there are other factors in configuring your living space than display resolution.\n\n<strong>HD at Home<\/strong>\nWe should note that <a href=\"http:\/\/www.highdefdigest.com\/blog\/ultra-hd-not-always-4K\/\">most of the content you\u2019re seeing at home is HD<\/a>. Movies that claim to be 4K likely spent some time as 2K (2048 x 1080) in the post production process as a <a href=\"http:\/\/www.editorsguild.com\/v2\/magazine\/Newsletter\/MayJun02\/digital_intermediate.html\">Digital Intermediate<\/a>. While special effects are natively rendered in 2K. After the movie is completed it can be scaled to 4K.\nStudios do this because it is more efficient, requiring less rendering and transfer time. In a theater, you won\u2019t be able to tell the difference unless you\u2019re in the first few rows. And, even then, you might only be subconsciously aware of it. So there is little motivation for studios to invest in 4K when the appreciable benefit is so low.\n\n<strong>What is HDR?<\/strong>\nMany 4K Ultra HD displays offer High Dynamic Range (HDR) and wide color gamut, which arguably offers differences much more perceptible than resolution alone. But as far as resolution goes, 4K Ultra HD is more than enough for right now.\n<a href=\"http:\/\/pic.templetons.com\/brad\/photo\/pixels.html\">Scans of 35mm film<\/a>\u200a\u2014\u200adepending on what lenses were used when shot\u200a\u2014\u200acan resolve 7000 pixels, but that level of imagery also increases grain. 5,600 pixels across, subjectively speaking, is the best quality for the most tolerable amount of grain.\n\n<strong>What about 8K?<\/strong>\nThere is already talk of <a href=\"https:\/\/en.wikipedia.org\/wiki\/8K_resolution\">8K resolution<\/a>, but like 4K Ultra HD, you will need to be sitting at the distance where the resolution becomes perceptible. The push for 4K came along because display technology\u200a\u2014\u200aand cameras\u200a\u2014\u200aadvanced to the point of providing it. The cart was pushing the horse.\nNow that we have had 4K Ultra HD displays in the marketplace for over three years, we are seeing <a href=\"https:\/\/www.cnet.com\/news\/where-can-i-get-4k-ultra-hd-tv-shows-and-movies-today\/\">a growing library of 4K Ultra HD content<\/a>, from Amazon and Netflix original series to Ultra HD Blu-ray Discs. However, it will still be a while before we can watch all our network shows and sports in 4K Ultra HD from our cable and satellite providers. (Note: some satellite providers have a few sporting events in 4K Ultra HD).\nSo we likely won\u2019t be seeing much, if any, 8K in theaters\u200a\u2014\u200aonly on our home TV or set-top box. And for the time being, you\u2019re mostly getting 2K\u2019s worth of resolution.\nThe real draw of 4K Ultra HD displays is their ability to offer HDR and wider color gamuts, which we\u2019ll delve into in another post.","protected":false},"excerpt":{"rendered":"Does 4K Ultra HD really matter? by John Ender, T.A.S.A.
