After you shutdown the system the monitor should go to sleep or stand by mode and this is managed by the motherboard itself not by the video controller driver.

You might need to try updating the BIOS of your Asrock motherboard and check with another video monitor and check with Asrock if the issue persists.

For BIOS updates you can refer to:
