Why Do We Need 4K Upscaling?

4k TVs are quite common today and this TV screen has a resolution of 3840×2160 pixels. However, 4k screen doesn’t mean 4k contents.

You may get 4k content when you have an ultra HD Blu-ray player, or a Premium subscription on Netflix, or a 4K TV channel coming into your TV via a 4K set-top box.

But some contents still are FHD or HD and you get zero benefits of 4k screen if the contents are not in 4K resolution. This is where 4k upscaling comes into play. 

1080P in a 4k screen means a quarter of the screen is filled with details and one-fourth are blank.

So for having a more detailed and sharpened view, this upscaling technology is performing as a revolution.

It assumes the blank place’s content from surrounded pixels and sharpens each and every pixel’s content to give it a good fit on a bigger screen.

That’s why we can watch such good quality videos on 4k screens.

So, for having a clear and detailed view, you have to admit 4k upscaling’s magic. Though it is not improving video quality but yet ensuring a better view. It is making your content more attractive.

What Is The Difference Between A 4K Upscaling And A Native 4K?

4k upscaling is the process of enhancing lower resolution input resolution to 4k. Suppose, you have a content of 1080p or FHD( 1920 ×10980). But you want to watch this content on a 4K screen.

So, an upscaler will upscale the resolution from 1920 ×1080 to 3840 ×2160. On the other side, native Native 4k means the original resolution of the content is already 3840×2160 pixels. 

Although both videos have the same resolution, they don’t have the same quality.

That’s because the upscaling process only increases the pixel count, not the information.

As the information is the same in both upscaled 4k and 1080p, you won’t find any major difference between them in terms of quality.

But native 4k will contain more information and will be more detailed. The content quality will be better than 4k upscaling.

Original 4k will also have a better color balance.

4k native is always better than an upscaled 4k. But you’ll need the upscaling when your TV screen is 4k but the content is not.

Conclusion

Which one is your best 4k upscaler box among the four? Go for one which will come with great audio and video.

If you have a constrain in your budget, I have some options for you as well.
