Just upgraded my iMAC to Ventura 13.0 and my second monitor has stopped working.
Having googled, it seems this has been a problem in Beta but I wasn't aware I was upgrading to a Beta product (pretty sure it's not). Has this happened to anyone else?
Second screen is just a TV monitor attached via the lightening port in the back of my iMAC.
Have tried unplugging from Mac, & powering off (just monitor) then entire set up.
Any suggestions?
TIA 🌻
