At present, the screen resolution of smart devices rarely exceeds 2K. Does that mean that we can’t watch 4K or HD video on smart devices? What is the relationship between video resolution and the resolution of display device?

The video finally displayed on the screen is divided into three processes: decoding, output, and display. Decoding refers to the process of decompressing digital video, which is mainly divided into hardware decoding and software decoding. Hardware decoding is mainly decoded by GPU, while software decoding is decoded by CPU. The output process refers to the way to connect the playback device with the display mainly through HDMI and DP port. Display refers to the display device that presents the final picture.

When the display is separated from the video playback device, all these three parts are needed to meet the demand of 4K play if you want to watch a 4K video. That is, the processor supports 4K decoding, the display has 4K resolution, and the mainframe and display are connected by HDMI or DP.

Taking CHUWI Hi10 Air as an example, let’s see how it performs when playing 4K video.
