Go too far, and the image will look identical to 1080p HD. However, any distance between 4 and about 8.5 feet will be enough to appreciate the difference between 4k and 1080p on a 65 inch TV. So, for example, if you have a 65 inch TV, the viewing distance at which the eye can actually process the details of 4k content is about 4 feet. Each line represents the optimal viewing distance for each resolution, but any TV that falls within the range of that color will be suitable to notice a difference in picture quality.

This chart shows the point at which an upgrade in resolution becomes worth it depending on size and distance to the TV. Learn more about the difference between 4k and 8k.Īll that said, everyone's eyesight is a little different, and most TVs now are at least capable of 4k, so visual acuity isn't really the best way to find the right distance. It should instead be used to figure out the closest you can sit to a TV without hitting its resolution limitation. Because the pixels are more densely packed with an 8k resolution, you need to sit closer to actually resolve those details. For that reason-content aside-8k only really makes sense if you want a really big screen and plan on sitting close to it. However, this also decreases the point at which the perceived difference in picture quality becomes noticeable. With 8k TVs, that density increases further, making it even harder to notice flaws with the resolution unless you're sitting extremely close. You need to be quite close to a fairly large TV for the pixels to be noticeably distracting. Since 4k TVs have such a large density of pixels, it's much more difficult for this issue to arise. So, if you sit too far, your eyes won't be able to resolve the image, but if you sit too close, that image will appear pixelated. For lower resolutions, you have to sit a bit further than preferable to not notice the pixels, while 4k resolutions and higher give you more freedom.įor instance, sitting close to a 1080p TV can look almost like watching through a screen door because you can see the individual pixels, even if it's playing a high-quality 1080p HD movie. Increasing your distance to the TV also increases the density of details, producing a better image. At a certain distance, depending on your eyesight, your eyes won't be able to distinguish every detail. Our ability to resolve details is determined not only by visual acuity but also by distance.
The closer you are, the lower your perceived pixel density will beĪngular resolution is the point at which the eye can 'resolve' or distinguish individual details in an image. Experts suggest that someone with 20/20 vision (or 6/6 using the metric system) can distinguish details that are 1/60th of a degree apart.
