"What is the best 4K upscaling solution to upscale videos from 480p, 720p, 1080p to 4K for playing better on my home 4K TV? Thanks." - James McInnes

4K Upscaling is a rising demand because people tend to stream 4K content on 4K Ultra HD TV. Over the past decade years, 4k TVs (such as TCL 50S425, Sony X900H, and Samsung UN65RU7300FXZA) started to dominate the TV market. The function in a 4K TV increases the incoming resolution to render on the 4K screen. Because a 4K TV has four times as many pixels on the screen as a 2K 1080p TV, it analyzes the incoming signal and "fills in the blanks" for non-4K content. That’s why you may need 4k upscaling.
