4K vs 8K TV Review – Which is Better?

The future looks in bright resolution and with 4K TVs becoming mainstream just as premium brands launch their 8K TVs, the fight amongst the brands themselves has been intense. Both of them are incredible and have brilliant picture quality among other things. 

Then what is it that makes an 8K TV different from a 4K TV? In this article today, we are going to compare and conclude who is the winner and if so, in what games. 

While we know a lot about a 4K TV than we know about the 8K Models, we are going to make point comparisons and determine what is what? For this, we are going to compare Samsung’s flagship 8K TV, the Q900R to the top tier 4K TVs in Samsung’s 4K line. This is because of all the companies out there, Samsung’s Q900R is the first consumer focussed and buyable product there is. 

Picture Quality:

One of the fundamental differences between an 8K TV and a 4K TV has to be the picture quality and the underlying screen resolution. A 4K TV comes with a native pixel resolution of 3840 x 2160 pixels whereas an 8K TV comes with a native pixel resolution of 7680 x 4320 pixels which is by numbers, 4 times larger than a 4K TV.

As we paint it in the picture, you can easily say that there is not a lot of visible side by side difference between the picture quality of a 4K TV to that of an 8K TV. When you stream Standard definition content on either of the TVs, you can safely say that visibly, there is not a lot of difference. If there were some enhanced resolution embedded into the TV, that would be for your perception but not for the immediate visual difference. 

But when you think of the technology involved in this, it would be astounding. For any other content that is not of standard definition, 8K Upscales the picture quality that a 4K TV cannot. On one hand, you would find no difference in watching regular TV but on the other hand, when you wish to switch to high definition content, 8K upscales the image to make it look natural way better than 4K. 

This brings us to the next important point

Native Content

The overall image quality of an 8K TV is attributed to the content that is being streamed on it. Native 8K resolution refers to the content being generated in 8K Format. When you stream 8K Native content onto an 8K TV, that is where the real magic lies and is visible. 

Earlier, 4K TVs had not so good upscaling even for full HD content and 8K solves that problem with no tear whatsoever. Even so, the preliminary models of 4K TVs had trouble even showing full HD content without pixel problems.

Apart from the Q900R, a lot of other 8K TVs to use ai Upscalers and machine learning for bettering the image quality. This gives us a trusted and hope for a promising future. You can expect the Q900R can upscale 4K content from native 4K to 8K Resolution as well. 

There is also the point that in reality that there is not a lot of native 8K Content available yet for us to entirely judge and compare a native 4K and native 8K.  But from the available content, you can safely bet that 8K has some of the most promising picture quality known for the human eye.


8K Has better details, crips image quality covering all the 3 dimensions in comparision to 4K TV but the lack of native 8K Content availability means we need to wait for some more time.


The next big thing that differentiates TVs is the features that they possess. Here, we cannot exactly compare a broad scale 8K TV with a generic 4K TV so we would again be comparing the Q900R Samsung 8K TV with the Q9FN Samsung 4K TV set. 


Have a look at the following picture


On the left is the Q9FN, 4K TV whereas on the right is the QLED 8K TV by Samsung. Both of them have been turned off and you can see the black factor yourselves. 

The QLED 8K, even when turned off has a higher black factor and can absorb light and has 0 glare compared the reflective surface of the 4K TV. The TVs both have dimmable backlight LEDs of about 500 but the intensity varies. 

Coming to the actual brightness, the QR900R has an impressive 3000 nits of brightness (other brands of 8K TVs have about 4000 nits) whereas the Q9FN 4K TV has a decent 2000 Nits of brightness. While the 4K’s 2000 nits are great and large, it is the massive brightness of the 8K’s 3000 and also the fact that it does not cause eye fatigue, it is the best. 

Verdict: The Q900R 8K TV


In order to fuel all the massive number of pixels, both the 4K AND the 8K TV need to have better and stronger processors. Processors in smart TVs are often proprietary because the companies compete to get what they believe is the best out in the store. 

The Q900R comes with a quantum processor that has the ability to upscale any and all non-native 8K content to native resolution. This is great given that we won’t be having native 8K Content anytime soon and this will help you watch real-time television with amazing quality and clarity. 

Verdict: 8K TVs because as of now, the latest 4K TVs do not have better image upscaling to match native resolution yet.


This is a single department where we felt that both TVs do pretty much the same. Almost both the TVs usually come with the same number of HDMI ports, USB Ports, optical output ports and much more. 

Given that both TVs are smart TVs, they come with the same connectivity options. The internet through WiFi, Bluetooth compatibility among much more. Even the streaming services such as Netflix, Amazon Prime, BBC, Youtube and other things stay the same or are available in the same abundance. 

But given the fact that 8K TVs are more about adapting to native resolution, some of the internet streaming might cause slight (almost negligible) disappointment to you compared the seamless streaming of a 4K TV. 

Verdict: 4K TV by a very slight and almost non-recognizable margin for their available content adaptability


Firstly, you would not be depending on the internal speakers of a smart TV and would most probably have a separate sound system that would compliment either the 4K TV or the 8K TV that you would be buying. 

But if you are anyhow going to depend on the TV’s internal sound systems, then an 8K TV hands down has the best sound system. Not just the Samsung sound but most of the 8K TVs come with an internal sound system that is brilliant and almost demands nothing else. 

Verdict: 8K TV

Final Verdict:

The simple verdict would be that the 8K TV is definitely better than a 4K TV but when you actually boil it down to everything, there is not a lot of difference. You would obviously be spending almost double the money on better picture quality and AI Processing and this would be justified if you are someone who wants to have a brilliant content experience irrespective of the cost. 

You could say that there is no added advantage for the more pixels nor are there any disadvantages. If the newer models come with even more advanced AI performance, backlighting, and at a competitive pricing, then the answer would be DEFINITELY 8K TV. But until a better and consumable 8K TV is available on the shelves, it is okay to go with a 4K TV too.
