How to Upscale 1080p to 4K on Windows PC with 4K Upscaling Software

The best 1080p to 4K converter makes your 1080p videos perfectly compatible with 4K displays and 4K-supported sites.

4K obviously has become something of a hit. It is gradually supported by more and more TVs, computers, cameras, smartphones, UAV, car driving recorders, video-sharing sites like YouTube and Vimeo, and so on. Despite that, 1080p sources still domain the market and 4K content is limited currently. Thanks to 4K upscaling technology built in 4K TVs, we can play 1080p videos on 4K TV without black area surrounding. However, output quality varies with the inbuilt 4K upscaler. Cheaper 4K TVs usually come with sub-par scalers. So in this case, we possibly won't see any quality enhancement. Worse result is also possible. If this is the case, you might as well upscale 1080p to 4K using the method here and see if the output is better than that processed by 4K TV itself.

Not only can you upconvert 1080p HD video to 4K for playback on 4K Televisons, but also convert 1080p to 2160p 4K for uploading to YouTube, Vimeo and the like. According to post "Upscaling 1080p videos for YouTube and Vimeo" on Time in Pixels, the video will look better on a 1080p screen if we upscale 1080p to 4K for YouTube and select the 4K option. So, how to upscale 1080p HD video to 4K UHD video?

To begin with, we should download 4K upscaling software - WinX HD Video Converter Deluxe [Intel QSV and NVIDIA CUDA/NVENC hardware acceleration supported]

upscale 1080p to 4k

This is a professional yet simple-to-use video converter utilizing superb upscaling algorithm to upconvert 1080p to high-quality 4K in MP4 to fit for 4K TV, YouTube, etc. It runs well on Windows 10, 8, 7 and others. A Mac version is also available.

Is Hardware Acceleration Crucial for 4K Video Processing?

Yes. Hardware acceleration technology is able to shift computing-intensive tasks, especially high-birtate 4K video processing, from general-purpose CPU to dedicated GPU hardware. In this way, we can see remarkable speed boost, CPU usage and temperature reduction.

WinX HD Video Converter Deluxe, already specially optimized for 4K videos, applies the advanced Intel QSV and NVIDIA CUDA/NVENC hardware acceleration technology to the entire video process (decoding, processing and encoding), which is called level-3 hardware acceleration. It is the only video converter reaching this level.

This is because it adopts unique motion adaptive pixel scaling algorithm, which adds new interpolated pixels calculated by the nearest sample points and controls the degree of diffusion/sharpening based on the input image.

In addition, this 1080p to 4K upscaler incorporates High Quality Engine and supports adjusting quality level manually, all these features along with the advanced upscaling algorithm making it deliver better quality as compared to that conducted by the inbuilt 4K upscaler of 4K UHD TV. By the way, Deinterlacing engine empowers you to change video from interlaced to progressive scan mode and then helps upscale 1080i to 4K.

Upscaling full HD to UHD video will be done at super fast speed, because this video scaler supports the world's most advanced level-3 Intel QSV and Nvidia CUDA/NVENC powered hardware acceleration, MMX-SSE, Hyper-threading and AMD 3DNow! tech.
