What is 8K resolution? All you need to know

8k resolution

Most likely, if you’ve spent any time shopping for a new TV, you’ve heard about 8K, which makes the promise to have the greatest possible visual resolution. 8K Ultra HD TV, which offers a staggering four times the resolution of 4K, is undoubtedly a revolutionary new format that follows recent improvements in picture quality.

The issue is that there is hardly any 8K content accessible to watch on these new 8K TVs, in addition to the fact that they are significantly more expensive than their 4K counterparts.

According to Mike Fidler, executive director of the 8K Association, any AV aficionado seeking “the ultimate entertainment experience” should consider any of the current 8K models. However, as was seen with the introduction of HDTV in the late 1990s, hardware usually reaches the market much ahead of content.

In actuality, 4K content is still catching up, despite the fact that 4K Ultra HD TVs have been on the market for almost ten years.

What is 8K?

The newest TV format is 8K Ultra HD TV, which quadruples the resolution of 4K. According to the calculations, a screen with 7,680 horizontal and 4,320 vertical pixels would have a total of almost 33 million pixels (which are only the individual picture elements that make up a TV picture). When compared to a 4K TV’s 3,840 x 2,160 and 8 million pixels, there is a noticeable difference.

A picture gets sharper, more detailed, and brighter the more pixels it has. You can sit closer to a large panel — a 77-inch screen, for example — and still not be able to see the individual pixels that make up the image thanks to 8K resolution. You consequently get a more lifelike, theatrical experience.

A sun rising on the horizon, for example, would have “better circles and curves” with 8K resolution, according to Robert Zohn, president of Value Electronics in Scarsdale, New York, whose prestigious annual TV Shootout selects the best TVs for that particular year. According to him, “you don’t have jagged edges at all, so a circle is more accurate” because the pixels are smaller and closer together. Additionally, colour seems more vibrant in 8K. Colors in 8K are not only more realistic but also more saturated. For instance, flesh tones are more sophisticated.

What Else Do You Need for 8K?

8K video needs high-speed channels leading into an 8K screen in addition to that. 8K video requires a large amount of bandwidth because it has four times as many pixels, each of which can hold different amounts of information. Whether you’re streaming 8K content via Wi-Fi or 5G internet or watching it on an as-yet-uninvented 8K optical disc, that is an issue.

Unless the TV is receiving the stream itself, 8K requires at least HDMI 2.1. HDMI is used for both cords and home theatre equipment. This guarantees that the source devices and your cables are capable of supporting the bandwidth needed to transport 8K information.
