How to control 4 digit 7 segment display with MAX7219 module

In this video I am controling 4 digit display with the max7219 module that is normally used to control 8x8 led matrix.
The reason for this is to research possibility of using this module to build large custom 4 digit seven segment display that can be used to build a clock.
