I notice various issues regarding external monitors but none specific to the issue I have and wondered if there was anyone else having the same or know of any troubleshooting tips?

I've got an M1 MBA with a USB-C hub attached and an external monitor connected via HDMI.

Every so often I'll get a quick flash of static - almost a horizontal line across the screen - it shows up for various amounts of time, sometimes a fraction of a second, sometimes the entire screen for a second.

Not sure what I can do to resolve it... I've changed the hub and the HDMI cable but it still occurs.

Is it something I can change in the display profile, or would a USB-C monitor perform better?
