Send what is to be shown on the display, say for example the current time in hours, minutes and seconds, from an arduino with a radio device, say an nrf24L01. Another arduino with both a matching radio and the three MAX7219 receives the transmission and displays that data.

Here is a tutorial Insight Into How 433MHz RF Tx-Rx Modules Work & Interface with Arduino

You cannot connect MAX7219 chips directly to the receiver. You need an arduino to interpret whahas been sent and control the MAX7219 chips.

yes am using arduino

Perfect. Then I suggest that you start by connecting the MAX7219 chips to one of the Arduinos, the one which will used with the receiver, and test it. If necessary, Google for MAX7219 tutorial. After that, start integrating the radios.
