Send image from the pc to STM32H7 attatched screen

How can I send a QR-code image from my PC and show it on the STM32H7 attached screen via the serial port? It’s meant for test automation, I need to send different QR-code images (Black and white) and show them on the screen , of course, one at a time.
Any tips ?
Codes on the Pc side, and the STM32H7. Which is the best communication type/ port /(protocol)?
