Fastest GPU Accelerated 1080P to 4K Converter

Theoretically, you won't see true ultra high definition effect when playing 4K video on 1080p TV, out of the physical limit of your display resolution. But 4K video does look better and clearer on 1080p monitors compared with videos in 1920 x 1080, for its four times more pixels, or rather YUV data. So, by analogy, can we say that 1080p native definitely looks worse on 4K UHD TV? Should we stretch 1080p manually to play in full screen on 4K display? If video quality degradation is an inevitable problem that upscalings face, is 1080p to 4K converter the best option to keep the highest possible quality? Let's see the following quick quizzes.

FAQs about Converting 1080p to 4K

Q: Is it possible to play a 1080p video clip on 4K TV?
A: Of course 4K TV plays 1080p video. Playback error is mostly caused by incompatible video codec and has nothing to do with video resolution.

Q: How does 1080p native look on 4K/UHD TV?
A: It depends. There could be three different results:
• 1080p looks the same on a 4K TV after upscaling as it would on a standard HD 1080p TV.
• 1080p looks slightly or significantly better on 4K TV than on 1080p monitors.
• 1080p looks terrible on 4K TV.

Q: TV vs. video converter software on the upscaling quality from 1080p to 4K?
A: The short answer is HD video converter does far better than TV incorporated upscaling sets. Most of the time for most televisions, be it 4K or 1080p, auto upscaling makes the stretched image look worse in full screen, while HD 4K video converter software, for example WinX HD Video Converter Deluxe, upconverts 1080p to 4K with amazingly good quality. Why? It's all because of its 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.
