When Was 4k Invented and Come Out?

A lot of people are wondering: When was 4K invented and come out? There is little information online as to the actual origins of 4K. Therefore, let’s see when the 4K resolution was introduced to the public.

The 4k format, which is also known as ultra-high definition (UHD), started making its way into the market in 2001. Back then, it was considered a niche product that was only available in the form of high-end televisions.

In this article, I will explain everything there is to know on this topic. I will begin by explaining what the 4K is and why it is important. A short history of 4k is also included. Let’s check it together!

When was 4K invented?

when did 4k come out

The 4k format has been around for quite a while, but it hasn’t had a lot of real-world applications until recently. 

So when did 4K start?

Even though graphic processors reached 4k format in 1984, it wasn’t until 2001 that the first 4k display was launched. 

The turning point started in 2001 when Sony launched the world’s first 4K display.

4K is the new standard for high-definition video resolution. It is known as Ultra HD (UHD) or Ultra High Definition (UHD). 

4K has four times as many pixels as the 1080p HDTVs and it offers a much sharper picture.

In September 2007, Sharp introduced the world’s first LCD monitor with a resolution of 3840 x 2160 pixels and named it Quattron+. 

It cost $10,000 at launch but was discontinued when Sharp released its 55-inch Aquos LC-60LE846U television in March 2008 with a similar resolution at $2,499.

Today, 4k is a standard feature on most new televisions and monitors, and it’s becoming more common among smartphones and tablets as well.

When did 4K come out?

So, when did 4k TVs come out? 4K TVs were launched on the market in 2012. 

However, initially, they were very expensive, and not many people could afford them.

The first 4K TV models cost $20,000 and the cheapest ones were around $4,000. In addition to that, there was a lack of content available in 4K format.

The first 4K TV prototype was introduced by Japanese manufacturer Sharp in September 2008 at the International Broadcasting Convention (IBC) in Amsterdam. 

It was called Quattron Pro 40-inch LCD TV and featured four sub-pixels instead of three – yellow, blue, and red plus white subpixels for better contrast between gray tones.

Nowadays, you can find a lot of affordable 4K TVs on the market and there are also plenty of movies and shows that you can watch in 4K quality.

Some other factors have made 4K televisions more popular than ever before:

  • The rise of streaming services like Netflix and Hulu has led to an increase in demand for high-resolution televisions because they offer better image quality than their 1080p counterparts
  • High-definition content is available on more platforms than ever before (e.g., Blu-ray discs, streaming services)
  • As more people have access to internet speeds above 100 Mbps (the minimum required bandwidth for 4K streaming), they’re interested in purchasing a new TV that supports this high resolution.

Who Invented 4K resolution?

The resolution of a video display is the number of pixels in each dimension that can be displayed. 

Video displays have varying resolutions depending on the technology used to create them. So, who invented 4K resolution?

In 1984, Hitachi invented a processor which was capable of displaying up to 4K resolution.

This processor was used in arcade machines and TVs during the 1980s.

The first consumer device that could display computer graphics at this resolution was the Atari 520ST in 1986. 

The Amiga 1000 followed shortly after with a similar spec but at a higher price point. 

In 1988, Commodore released their Amiga A1000 which could display 256 colors on screen simultaneously from a palette of 16 million colors!

In 2009, Sony released its first digital camera capable of shooting 4K video at 24 frames per second. 

In 2012, Samsung and LG introduced their first 4K televisions to consumers with a price tag of over $10,000.

What does 4K UHD mean?

4K is a TV resolution of 3,840 x 2,160 pixels. It’s also known as Ultra HD (UHD), and it offers four times the resolution of current 1080p high-definition TVs. 

That makes for a clearer picture with more detail.

The first 4K TVs started arriving in 2012, but they were really expensive. By 2015, prices had come down enough to make them a viable option for many consumers. 

Now they’re the norm rather than the exception.

Types of 4K resolution?

4K has more types of resolution, depending on the media device. Here are the most common types of 4K resolution:


The 16:9 resolution is one of the most common types of 4K video. It is also known as HDTV, and it is used in many common devices like televisions and computers. 


This is an aspect ratio standard used by theaters that use 4,096 vertical lines instead of 1,920 horizontal lines.

Because this aspect ratio is wider than 16×9 (which is 16 units across for every 9 units up), it can’t be displayed on typical TVs without scaling or cropping its image (or both).


16:10 (2,560 x 1,440 pixels) is a standard resolution for professional use in digital imaging and visual effects. 

This format is also known as DCI 4K (Digital Cinema Initiatives).

4K vs 8K resolution

Who Invented 4k Resolution

These days, people like to compare the 4K vs 8K resolution. 

8K is a resolution of 7,680 by 4,320 pixels and has 4 times as many pixels as 4K UHD which is 3,840 by 2,160 pixels.

In other words, it’s four times the resolution of a 4K UHD TV and 16 times more pixels than a 1080p HDTV.

The average human eye can’t distinguish between two resolutions that differ by more than 50%. 

So for most people sitting 10 feet away from the TV (assuming 1080p), 8K is just too far out there and unnecessary for most people at this point in time.

As you can see, 8K is going to be a long time coming. It’s just not feasible for most people at this point in time. 

But if you’re looking to future-proof your home entertainment center and want 

When was 8K invented?

The first 8K TV was introduced in 2012 by Sharp. But it was not a success in the market because of its high price and poor picture quality. 

The resolution of 8K TVs is 7,680 x 4,320 pixels which is 16 times more than the full HD resolution (1,920 x 1,080).

Today, in 2019, only a few companies are making these TVs and they are very expensive. 

You can buy an 85-inch 4K TV from Samsung for $1,500 but an 85-inch 8K TV from Sony costs $25,000!


Still interested in this topic? Let’s check some of the most frequently asked questions about when was 4K invented.

Why is 2160p called 4K?

The word “4K” is used because the pixels in the image are around 4,000 pixels wide. The term “2160p” is the formal name for 4K resolution, but it’s not as commonly used.

Is 2560 x 1440 considered 4K?

2560 x 1440 is not 4K. It’s called Quad HD and it has 1,440 vertical pixels and 2,560 horizontal ones.

What is the highest resolution a human can see?

The answer is that it depends on how far away from the TV you sit. If you sit close enough to a TV, it makes no difference how large the screen is. The pixels will always be visible.


To conclude, 4K resolution, also called 4K ultra HD, is the modern generation of display resolution that was made to provide viewers with a far better picture than the plain HD has ever provided.

But let’s be clear about it: technology is developing at an immense speed and soon we won’t ask when was 4K invented and come out.

Instead, we’ll talk about 8K and even some other futuristic 3D displays.
