8K Resolution: Is it practical?

November 27, 2017 by Sean Kupiec

With the increase in popularity of 4K resolution displays, consumers are now faced with the introduction of 8K displays. With this introduction of Dell’s 32in. 8K display priced at a whopping $5,000, people are starting to ask, “Why?”

Displays with 4K resolution have started becoming widely accepted as the new norm. However, most content for residential consumers has not yet reached the full potential of 4K. With that being the case, what is the point of 8K? 8K is 7680 x 4320 px. Dell’s 32 in. 8K display is not intended for residential use, but rather for graphics professionals who want to get every bit of detail possible.

For industry professionals, 4K displays can be used to display much more content than HD displays. In a 4K display you can have much more legible text than that of an HD display at 1080p. Examples of practical use include airports displaying flight information, restaurants displaying menus and conference rooms sharing content. With this in mind, could the same business applications benefit from 8K displays? The short answer is yes!

Imagine, if you will, a 20 ft. by 12ft. wall all as a single display. With an HD resolution of 1080 x 1920, the pixels would be very large and displaying legible text would make the text large as well. However, with the 8K resolution of 7680 x 4320, the pixels are much smaller. This allows you to display much smaller text and still be legible. This increases the amount of content able to be displayed. If we shrink this analogy back down to a reasonable size of 65 in., the concept remains with 8K resolution; the pixels are much smaller allowing more content to be displayed while maintaining the legibility of the text. Another example of this is simply zooming out on any content. You can zoom out to the point where the text is not legible. Moving closer to the screen won’t help as the text has hit the legible limit for the resolution of the display. If you are viewing on an HD display, imagine being able to zoom out the content 4x what you just did and still being able to read the text. That’s the advantage of 8K resolution.

In conclusion, is it practical? For industry professional and public spaces, absolutely. For consumers, however, it is not practical at this time since mainstream content has not reached 8K quality.
