4K LED Display – Everything You Would Like to Know

Remember the days when 1080p displays were the shebang? Well, those days are ancient history because there’s a new player in town: the 4K LED display.

Unlike a measly 1080p display with barely any clarity, a 4K display lets you see everything in high definition. That means you can watch the eyebrow hairs of your favorite TV actor or actress move when you stream a Netflix, HBOMax, or Amazon Prime show. 4K is that clear.

But gross imagery aside, what is a 4K LED display? What makes it better than a 1080p display? Let’s find out.

What Is a 4K LED Display?
A 4K LED display, also known as 4K ultra HD, is a screen with a 16:9 aspect ratio and a 3840 x 2160 pixel resolution. It is four times the resolution of the standard 1080p HD. As a result, it produces crisp, high-quality, clear, and true-colored images without any noticeable image blurriness or pixel problems.

The display contains eight million pixels crammed into the space of just two million, which makes images clearer, more accurate, and have a higher dynamic range. This is done by making each pixel four times smaller than it usually is.

Do the Extra Pixels in 4K Displays Matter?
Honestly, it depends. If you’re jumping from 1080p to 4K, you’re going to notice more clarity and sharpness in your new display.

But if you’re sticking with a 40-inch display (the same one you had before) and used to sitting pretty close to your TV, then you may not see a difference. This is especially true if you’re still watching HD content instead of 4K shows and films.

Is There a Difference Between 4K and Ultra HD?
Not really, unless you’re a video production professional. In that case, 4K is going to have a 1.85:1 aspect ratio and a 4096 x 2160 pixel resolution. But that’s neither here nor here, and as a consumer, getting a hold of a TV with a 1.85:1 pixel resolution is kind of difficult. So, move on.

But what about the difference between 4K and UHD?
Well, UHD is another name for 4K. Here’s some backstory: in 2013, the Consumer Technology Association (CTA) decided that the official name for 4K should be ultra HD. Unfortunately, nobody picked it up, but as manufacturers had to follow the CTA’s guidelines, they started branding their 4K LED displays as “4K Ultra HD.”
So, in reality, 4K and UHD are two names for the same thing.

Are 4K and HDR the Same Thing?
The short answer is no. High dynamic range (HDR) is a feature that creates a higher contrast between the darkest and brightest parts of an image.

HDR deepens blacks and brightens whites, adding more depth to images and allowing you to see more detail in the lightest and darkest portions of images.

Where Can I Stream 4K Content?
You can use pretty much any streaming service to watch 4K content. Top contenders are Netflix, Apple TV, HBOMax, Amazon Prime, Hulu, Rakuten TV, and Disney+. Almost all of the original series and films shown by these streaming services can be watched in 4K.

However, streaming 4K content requires a 25Mbps or faster downstream internet connection, which is not something most people have.

What Cables Will I Need for 4K?
If you’re running a 4K show or film, you’ll need a high-speed HDMI cable or a DisplayPort. For the former, make sure you have the best HDMI connectors.

For instance, HDMI 1.4 connectors support a 4K resolution at 30 frames per second (fps), HDMI 2.0 at 60fps, HDMI 2.0a at HDR, and HDMI 2.1 at 120fps. Also, remember that an HDMI cable that supports 1080p will be able to support 4K, so you don’t need to break your wallet when buying an HDMI cable.

The Takeaway
4K is the champion of displays nowadays and is no longer only limited to those with deep pockets. Dozens of LED video wall manufacturers make 4K LED displays that can go as low as 40 inches to as high as 90 inches.

So, if you’re deciding between a 4K and 1080p display, go for the 4K. It has better quality, looks brilliant at a regular viewing angle, is brighter and crisper, and comes with HDR, which makes everything look more real.
