Why Should You Upscale 1080P to 4K?

4K technology is getting used in more and more devices and platforms. We now have 4K TVs, 4K computers, 4K-compatible sites like YouTube and Vimeo, and so much more. It would surely generate the best viewing experience to watch 4K content on one of these 4K devices. Yet the thing is that we don’t really have that much 4K content to play. As a matter of fact, it is still 1080P that dominates the market at current.

So can we play 1080P videos on 4K TVs or other 4K devices? The answer is yes, only that the video has to be upscaled to 4K resolution first. All the 4K TVs have their built-in 4K upscalers that will convert 1080P video to 4K automatically once you started the play. But these upscalers are not of the same quality. Some are good while some others are bad. And that’s why you can see blurry or worse upscaled 4K videos on some 4K TVs. To this matter, you will have to resort to external 4K upscaling software for a better result.

Upscaling 1080P to 4K is also a wise move if you want to upload a clearer video to YouTube, as YouTube will allocate more bitrate to your video and use VP9, instead of H.264, to encode your video, thus making your video even sharper.

Now comes the question, how to upscale to 4K? The answer is now obvious. You’ll need a reliable 4K upscaler. And in the following part, I will introduce one such video upscaler and show you how to convert 1080P to 4K in detailed steps. Read on!
