Uses for a Raspberry Pi 4 with a damaged HDMI port?

[/RaspberryPi]

I have a Raspberry Pi 4 Model B that I was using as a RetroPie machine. However, the HDMI port has become damaged, causing the display to drop in and out at random. Sometimes it's only for a few seconds, other times it lasts several minutes.

Since I wasn't skilled enough to replace the HDMI port, I bought another Raspberry Pi to use as my RetroPie. However, that leaves me with a Raspberry Pi that is functional aside from the display issues.

Any suggestions for what else I can use this Raspberry Pi for that doesn't require it to output a display?

My house does not have any automation, so I don't have much use for functions related to that. I am also not super technical (I know enough to realise how little I know), but I'm willing to give anything a go and learn from it.
