What is 8K Resolution and How it Differs from 8K Ready

Even though 4K resolution is not even fully implemented (currently almost three-quarters of users are still in Full HD), manufacturers are already starting to promote 8K resolution displays. In this article we are going to tell you what this resolution consists of , how many pixels it has , and how it differs from ” 8K Ready “, a substitute that is emerging in the same way as “HD Ready” screens were once sold.

At this time, there are already many TVs that have 8K resolution, although at quite prohibitive prices. Likewise, some smartphones are already capable of recording at this resolution, but do not think that it is a novelty since in the film format they have more than been long overdue. To give you an idea, a film recorded with a 35mm “roll” from 1892 already had a native resolution of 4096 x 3112.

What is 8K Resolution and How it Differs from 8K Ready

What is 8K resolution and how many pixels does it have?

As you know, the resolution of a screen is measured by two numbers: the number of pixels it has horizontally by those it has vertically. Thus, the Full HD resolution is 1920 x 1080 pixels, and if we do this multiplication we get that there are 2,073,600 pixels in total. It is important to know this data, since when we are on a PC, it is the number of pixels that our graphics card has to manage.

Now, as for the 8K resolution, so called because it is 8 times the HD resolution (four times 2K Full HD, and twice that of 4K resolution), it has 7680 x 4320 pixels , which translates into a whopping 33,177 .600 pixels . Imagine the work of a graphics card to move a game to that resolution.

Resolución 8K vs 4K vs Full HD

Some of you may wonder that if the 8K has twice the resolution of a 4K screen, why then does it have so many more pixels? The answer is that specifically it has four times more and not double because 8K is equivalent to 4 4K screens.

8K and 8K Ready, one more marketing hoax?

Years ago, when Full HD resolution was a first, many manufacturers used marketing tricks selling “HD Ready” screens that actually had 1280 x 720 (HD) resolution but were capable of displaying video at 1080i resolution (1920 x 1080 interlaced). , non-progressive (1080p)), with a much worse image quality since the video formats that it accepted were also distorted.

This is an example of what happened at the time, so are we facing the same situation with 8K Ready?

Pantalla de resolución 8K Ready

Unfortunately yes. We will soon start seeing 8K Ready displays, which although “8K ready” does not actually imply that they meet the standard’s requirements for true 8K resolution. In other words, 8K resolution is not the same as 8K Ready , this second being the cheap option that emulates 8K without providing all its advantages.

So when you see a screen labeled 8K Ready you should be clear that it doesn’t actually have 8K. For you to have in mind, these are the characteristics that an 8K resolution screen must have , of which some (or all) of them will not comply with those announced as 8K Ready:

  • Resolution panel 7680 x 4320 pixels.
  • Native ability to play content with 10-bit color depth.
  • Must have support for BT.2100 color space.
  • HDMI connection with HDCP 2.2 support.
