HD, 2k,4k, 8k Resolution Guide

Living in the digital era isn’t always easy. It is difficult to keep up with aspect ratio and resolution for PowerPoint Presentations. Here is a quick reference beyond this modern marvel of technology:

Resolution-6

 

Why is it called 2K-4K-8K?

An easy way to know what to call a resolution is to look only at the horizontal pixel count. 2K, 4K, 8K, etc. all refer to the horizontal resolution – approximately that number.

Note: For this post, all resolutions referenced are for 16×9 aspect ratio displays (with the exception of 2K).

HD (1920×1080)

HD, or High Definition, is used for two resolutions 1280×720 or 1920×1080.  These are commonly referred to as 720p or 1080p (see this post that explains “P” and “I”). I am going to refer to 1080p as HD.

Resolution-1

2K

HD, or High Definition, almost 2K, but not quite. 2K resolution is 2048×1080. It is a long story why computer displays did not just go with 2K, we’ll save that for another post. But needless to say, true 2K resolution is not used a lot in an HD world.

Resolution-2

4K

Like HD, 4K is actually 2 different resolutions depending on the context. The resolution we use for PowerPoint resolution and 4K monitors is called UHDTV 4K @ 3840 x 2160 pixels. The film industry will use 4096 x 2160 pixels, but this is not a 16×9 aspect ratio so it is not a part of this discussion and something you will most likely never use.

Resolution-3

8K

Yes, I am skipping 6K (noted below), because 8K is the next industry standard, also called UHDTV 8K @ 7680 x 4320 pixels. This is a lot of pixels and yes we design presentations for beyond 8K projection!

Resolution-4

 

6K, 10K, 12K and beyond are all resolutions, but they are not industry standards. Here is a quick list of resolutions, that includes them for reference.

HD = 1920×1080

2K = 2048×1080

4K = 3840×2160

5K = 5120×2880

6K = 6144×3160

8K = 7680×4320

10K = 10328×7760

Yes, PowerPoint can handle any of these resolutions. It is not so much a question of can PowerPoint handle a high resolution as it is can the computer and monitor/projector handle the high resolution. In addition, many stage events we develop presentations for use an array of side-by-side projectors to create a custom resolution. Usually, it is an array of HD, 1920×1080, projectors, so (and I am simplifying the details) a 4 projector wide setup will create an 8K wide by HD height image. TLC then creates a custom PowerPoint for the 7680 x 1080 pixel resolution, which we generically refer to as “Ultrawide Presentations.”

Gigapixel.com – Amazing Technology!

Gigapixel.com is a service that produces extremely high resolution images. A Gigapixel image is a digital image bitmap composed of one billion pixels (1,000 megapixels), or more than 100 times the information captured by a 10 megapixel digital camera.

For example, here is a photo of the mass crowd of Canadians at the Vancouver Canucks Fan Zone along Georgia St. for Game 7 of the 2011 Stanley Cup Final. The image was captured at 5:46 pm on June 15, 2011. It is made up of 216 photos (12 across by 18 down) stitched together, taken over a 15-minute span, and is not supposed to represent a single moment in time.

Note the zoom control in the left portion of the above image. Here is maximum zoom on the image! This street sign is where the red arrow above is pointing. Plus you can pan around and identify virtually everyone’s face.

Of course, this image is 69,394 X 30,420 pixels (or 2,110 megapixels). A widescreen PowerPoint slide image through an HD projector or monitor is 1,920×1080 – we have a long way to go before needing this resolution for presentations, but it is amazing!!

Display Standards Chart

While researching an upcoming article I found this incredibly detailed illustration of the various display standards out there. Understanding the various display sizes is important when designing a presentation that will viewed on a non-standard aspect ratio (eg. wide screen).
