4K is now available in digital theatres, on-demand streaming services such as Netflix, Amazon Prime Video, Disney +, and most home televisions. It has two resolutions: 3840 x 2160, which is known as Ultra High Definition or UHD, and 4096 x 2160, which is formally known as 4K. Compared to 1080p and 720p, 4K is optimal for big-screen displays and provides a superior viewing experience for gamers, movie fans, and TV viewers.

With the growing popularity of 4K Ultra HD Blu-rays, 4K streaming services, and 4K TVs, demand for 4K videos are steadily increasing, owing to the stunning video quality that 4K provides. Apart from viewing 4K videos online and purchasing 4K Ultra HD Blu-rays, there is another way to get more 4K media: using AI video upscaler to improve 1080p videos to 4K.

4K vs 1080p: The Difference

1080p refers to videos with a 1920 x 1080 pixels resolution, while 4K refers to videos with a 3840 x 2160 pixels resolution. In terms of pixel resolution alone, 4K video is a significant improvement over 1080p, with four times the resolution of 1080p and more than eight million pixels compared to just two million pixels in 1080p.

When watching 1080p and 4K films on regular TV screens or your desktop/laptop displays, you may not notice much of a difference; but, as 4K TVs and monitors become more prevalent, you will see the difference when watching 1080p and 4K videos on that 4K screen. When played on 4K televisions, 4K videos convey more information than 1080p videos, making the video images look crisper, sharper, and cleaner, notably in the portrayal of hair, feathers, and skins.

Why do We Need to Upscale Videos to 4K?

Upscaling 1080p to 4k:Why do We Need to Upscale Videos to 4K?

You most likely already own or plan to acquire a 4K television. However, just because you have a 4K TV doesn't mean you'll be able to watch everything in 4K. If your 4K TV doesn't allow hardware 4K upscaling (which most modern 4K TVs do), you won't be able to watch non-4K or standard 1080p videos in 4K quality. And without some creative upscaling, full HD/1080p videos on a 4K monitor will merely look more prominent, not better.

As a result, if you don't want to invest in an Ultra HD Blu-ray player and buy 4K Ultra HD Blu-ray movies regularly, or if you don't want to stream 4K content from Netflix, Amazon, or any other 4K TV channel, upscaling your 1080p videos to 4K is the only way to get more 4K videos and get the most out of your 4K TV.

How to Upscale 1080p to 4K?

Upscaling 1080p to 4K can be accomplished in one of two ways: hardware or software. We'll go over this issue in-depth in this part.

Using Hardware

When shopping for 4K TVs in a physical store or online, you'll note that most of today's 4K TVs are labeled as capable of 4K upscaling. The 4K upscale feature in a 4K TV works as follows: soon after the video signal is transferred to the 4K TV, an analysis begins to determine what type and resolution the received video signal is, whether it's live TV or streaming, HD or full HD, and then noise reduction takes place. Edges, textures, and details are then evaluated and sharpened as needed. Finally, to match the native panel resolution, the signal is transformed to 4K.

Using software

Choosing a software 4K upscaling solution to get ai upscaling video over the native 4K upscaling that comes with 4K TVs is that you can always keep up with the latest AI technology, making 4K upscaling considerably easier. Machine learning-based Video Enhancement software can be significantly more intelligent: it can use previous and next frames to see what's truly there, then improve the final result.

Frequently Asked Questions

Is a 4K TV capable of upscaling 1080p content to 4K?

Yes, most 4K TVs today from major manufacturers such as Samsung, Sony, LG, Panasonic, and others include this 4K upscaling option.

Why do I need a 4K upscaling program when my 4K TV can already do it?

The short answer is that if your 4K TV already has a native 4K upscaling feature, you don't need a 4K upscaling program. Because manufacturers all have their own 4K upscaling algorithms, the output video quality of each 4K TV may vary significantly from one brand to the next. Some may give satisfactory results, while others may not. If you're not happy with the results, your only option is to use a software 4K upscaling solution; after all, changing to a new 4K TV isn't realistic.
