4K Vs 8K

Wasn’t it just sometime back that 4K TV was introduced? Well, in present scenario time and tide may wait but the world of technology certainly waits for none. It was in the year 2018 that the idea of 8K TV was shared and in today’s date you can find almost all the top selling brands displaying at least one model of an 8K TV of its own.

So, what exactly is all the fuss about? Does it really matter?

Let’s find out!

Taking forward the HD resolution of 1080 pixels to four times more pixels is 4k resolution. It has 8 million pixels which makes the viewing experience much finer than its older generation.

But the resolution alone does not decide how good the picture quality shall be. A number of factors come into the force to make up for the same, like: High Dynamic Range that we know as HRD, the contrast ratio etc. hence its not just the resolution that matters.

8K basically denotes the pixel strength. In 8K TVs one can expect a resolution of 7680 pixels horizontally and 4320 pixels vertically, which is four times the number of pixels available in 4K TVs, and 16 times more that you find in full HD. So, the total number of pixels comes down to 33 million.

Is there a need for moving from 4K to 8K at all?

Remember the time when you upgraded your TV set form full HD to 4K? The display quality of full HD is quite good, but once you upgrade it to 4K you see the difference!

The shift from 4K to 8K is a similar move.

In reality the difference between looking at an 8-megapixel picture and a 33-megapixel picture is huge. When you look closely into 4K television, you will find a mesh-like finish on the screen. When the same is done with 8k, this “Screen door” effect is barely visible unless looked too closely. For those who doubt if the extra pixels will be of any worth to the naked eye then, you must see it up close and see for yourself how dramatic difference it makes to the picture quality.

Content available on 4K TV sets Vs 8K TV sets

Initially the availability of 4k content was very little. But now there are multiple sources that produce 4k content, like: 


Manufacturers like Samsung, LG, Panasonic, Sony, Vizio, Philips, TCL, and Hisense or a TV compatible with 4K Ultra HD can stream 4kcontent ion Netflix. It now produces most of its content in 4k resolution!

Amazon instant video/prime

The above-mentioned brands can be used here to watch 4k content and a minimum of internet speed of 25Mbps is required to play the content.


To access content here, you’ll need a Apple TV 4K or Google Chromecast Ultra. It has content that can air both on demand that can be converted from a lower resolution to 4k and now it has 4k Hulu original content for the complete 4k experience.


Having YouTube app does not mean that you can access 4k content there, ensure that your brand of TV supports YouTube’s brand of 4k to enjoy 4k content!

For gaming

Both PlayStation 4 Pro and the Xbox One X can give you visible difference that gives 4k level of visuals. Although it must be noted that PS4 Pro does not support 4k resolution

The content availability in 8K TVs now is very poor. It is going to take a while before we get 8K TV content. The only exception here at this moment is YouTube which provides very little content in 8k resolution. And that’s why you’re seeing all these recommendations for 4k instead of 8k. As it’s quite better at the moment and also cost effective as well. published a great guide on 4k televisions that you can consider as a better investment. Just the recent development here shows that now three are content that can be displayed in a 4k TV that does justice to 4k. Only Japan’s NHK TV network has started to experiment with 8K content for broadcasting with its “Super Hi-Vision channel” that present events in both 4K and 8K, but till date they have only been shown in a couple of theaters around Japan. It has been announced that the 2020 Olympics being hosted by Japan shall be displayed in 8k. Hence, expecting 8k content to be readily available at this point of time would only deject you.   And just like how 4K TVs consume a lot of bandwidth, 8K will probably consume more. Since 8k content is almost nil in the market right now, it is going to take a super processor for the TV to process all the 720p,1080p,4k content into 8k content.

Viewing Distance

4k displays intricate details because of its high resolution. Having said that it is to be noted that if you are seated far too away, a human eye will miss the little details that this technology has to offer to dazzle our eyes with details that we don’t see on a routine basis. Therefore, it becomes important that the viewing distance is right so that you neither miss out on the details nor are you too close that you miss the whole picture!

Television Size














You could get the best of the paintings in the world and still not enjoy them if your eyes can’t gauge it entirely. Similarly, in order to enjoy 8k to its actual advantage, the TV is to be placed at a relatively larger distance.

The following illustrates the optimal seating distance from the screen of 8K TV:

Does 8k need specific devices to be able to function?

Yes, 8k does require new equipment to function at it best, and most importantly new cables. The brand new HDMI 2.1 best supports 8K resolution which runs at up to 60 frames per second, and 8k needs almost three times the bandwidth of 4K-capable HDMI 2.0! This means that the existent Blu-ray players, media streamers, and game systems can only do justice till the level of  4k and not 8k. For 8k the basic need is that one will need new HDMI 2.1- devices that are well equipped and able to process 8K video and display the output through an 8K TV, but they don’t exist yet and neither do the cables, and the HDMI Forum will be releasing its testing specifications for HDMI 2.1 products only until later this year.

8k TV- for gaming

Refresh Rate

It shows the number of times the image being displayed refreshes. The new chipsets increase the refresh rate and makes gaming much smoother.

Response Time

Depending upon the inputs, the time the pixels take to adapt themselves to display is the response time. So better the response time, smoother is the transition.

The picture quality in 8k is undoubtedly great and so is the refresh rate which can sometimes be the winning factor. The new 8k TV sets will come with new chipsets too making the screen process faster and eliminate lag.

Brands that manufacture 8k television sets:

  1. Samsung Q900FN QLED 85-inch 8K TV:

Just like its competitor’s version, LGs 8k OLED TV as the name suggests has OLED screen. It has its own backlighting making the set slim.

  1. Sony X1 HDR 8K TV
