Is there a fix for an external monitor connected to a M1 Mac Mini going black for a few seconds every few minutes?

Have tried connecting using HDMI cable as well as DisplayPort to USB-C cable (both are good quality cables). Had this issue very briefly early on right after purchasing the mini, but it went away after I switched to a new HDMI cable that came with the LG monitor. A year and a half later the problem is back and switching HDMI or DisplayPort to USB-C cable does not help. There are no issues when I connect the same monitor using the same DisplayPort to USB-C cable to my M2 MacBook Pro. So it does seem that the problem is with the M1 Mini.
