A resolution of 1280 x 720 pixels is 720p, which provides a total of 921,600 pixels. Its quality is better than the quality of SD but is considered entry-level HD. Compared to higher resolutions such as 1080p and 4K, 720p lacks the clarity and sharpness that viewers require nowadays, resulting in a less immersive viewing experience.
720p was widely utilized in early HDTVs, computer monitors, and gaming consoles.
4K (UHD) offers a higher resolution than 720p at 3840 x 2160 pixels and 4096 × 2160 pixels. It provides more details and clarity with vibrant colors, fine details, and smooth lines to enhance the viewing experience. 4K resolution offers better image clarity, especially when viewed on larger screens. It is widely used in digital television and digital cinematography. In television and consumer media, 3840 × 2160 is the dominant 4K standard, whereas the movie projection industry uses 4096 × 2160.
Though 4K videos offer better quality and clarity, you should note that higher resolution doesn't always mean better. The quality also largely depends on the device and viewing experience.
If you are watching the video on smaller screens or at larger viewing distances, you may not clearly find the difference between 720p and 4K.
If you hope to upscale 720p videos to 4K for playback, you should also keep in mind that increasing the resolution doesn't equal improving the quality. Though some AI programs can intelligently add details to the video, the quality still cannot be as good as the original 4K one.
Nevertheless, the following recommends 3 tools to help you upscale 720p to 4K if you desire to upscale your 720p videos. Just choose one according to your needs.

Yes, the difference between 720p and 4K is large. 4K boasts sixteen times the number of pixels of 720p. 720p resolution is the entry-level of HD quality, while 4K resolution offers more detail and clarity. So, the image quality of 4K is much better than that of 720p.
You can upscale a 1080p video to 4K to get better quality for playback on a 4K TV. However, you should always know that the upscaled 4K quality is never as good as the video shot in 4K.
720p content will not appear as well on a 4K TV as native 4K content, but it may still be watchable depending on factors such as the TV's upscaling technology, the content itself, and the viewing distance. If you want to watch 720p content on a 4K TV with better experience, consider upgrading from 720p to 4K or purchasing a TV with decent upscaling features to improve your viewing experience.
