What is 4K upscaling? Do you know how to upscale 1080p to 4K for quality play on a home 4K player? As is often the case that most people tend to stream 4K content on Netflix or Amazon, or purchase 4K Ultra HD TV for a better view at the home theatre. However, there might be times when you anticipate upscaling 1080p to 4K for a better play on 4K Ultra HDTV or 4K media player. Besides, streaming online means high investment in the long run. Considering this, this post introduces the best cost-efficient solutions to 4K upscaling with the best AI-powered 4k upscaler which is devoted to upscaling 4k for the sake of personal and business uses. Read on to find more useful details.

PART 1. 1080p vs 4K:What's the Difference?

1080p is known as Full High Definition (Full HD), while 4K is labeled as Ultra High Definition (UHD). In terms of resolution, 1080p equals 1920x1080 pixels, while 4K boasts 3840x2160 pixels. Since 3840p is close to 4000p in horizontal pixels, therefore comes the name 4K. However, the resolution is measured by vertical pixels, so 4K resolution equals 2160 pixels. Meanwhile, in terms of aspect ratio, 4K contains the number of pixels on a screen four times larger than that of 1080p. Thus, 4K video owns much clearer image quality compared with that of 1080p. Considering this, why not convert 1080p to 4K for better image quality? To achieve this aim, a 1080p to 4K converter will come in handy.

PART 2. What is 4K Upscaling? What is UHD Upscaling?

What is 4K upscaling? What is UHD upscaling? Shall I choose 1080p or 4k? When it comes to video or image, upscaling means converting low definition to a higher resolution. Thus, low-resolution content will fill the entire TV screen. For example, most people tend to upscale DVDs of low-res video to Full HD for better playback on an HD TV. Normally, there are four kinds of resolution: HD (1280x720), Full HD (1920x1080), Ultra HD/4K: 3840x2160, and Ultra HD/8k: 7620x4380.

8K TV calls for huge investments and high configuration, out of reach for ordinary consumers. Hence, 4K can be affordable for most people with advanced home theatres. One thing that needs to be mentioned is that Ultra HD is not equal to 4K in video production, but that poses no threat to its popularity among household consumers.

What is 4k upscaling?

Does 4K upscaling work properly? In a nutshell, 4K upscaling means upscaling 1080p to 4K, which reaches the resolution of Ultra HD Blu-ray. Thus, broadly speaking, we also call it Blu-ray 4K upscaling, 4K UHD upscaling, or UHD upscaling. In this sense, having a 4K UHD upscaler at hand is imperative. 

PART 3. Why Do We Need 4K Upscaling?

Everyone anticipates watching high-resolution videos. To meet user demand, video streaming services like Netflix and Amazon have started to offer online services for 4K video content. Nevertheless, to access 4K content, you shall go to some expense. Besides, most such streaming sites have limits on online streaming and offline download. Want Netflix download? Forget the Netflix app. In addition, the TV market has a mixture of real 4K TVs and fake ones. Meanwhile, as 4K begins to replace HD in-home theatre, manufacturers are unveiling interesting marketing jargon like UHD upscaling to engage consumers. They claim 4K upscaling enables 4K TV to take lower-resolution content and display it on the entire 4K screen.

However, a high price for a so-called high-end 4K TV does not means leading picture or audio quality. The best way is to check the product's official website, users’ reviews, or review sites to gain overall information. Does 4K TV upscale automatically? Some 4K upscaling TVs fail to satisfy personal needs. If time permitting, go to the store and test in person.

Warm tips: Top-end 4K Ultra HD TV such as LG C9, LG E9, and Samsung Q90R has in-built video processors that can perform video ai upscaling functions. Fortunately, smart users always spend every penny wisely. They would blaze a new trial by upscaling 1080p to 4K with professional 4K upscaler. What a smart idea! If you have a 4K TV at home that supports 4K content playback, all problems will be easily resolved. That’s to say, a real 4K Ultra HD TV plus 4K upscaler will lead to stunning 4K content playback.
