Hi, just upgraded my Mac Mini (2018) to Monterey 12.4. I've always used the Mini connected to my Sony television withouth any problems. But now the TV no longer gets a signal from the Mini. Looks like the external monitor problems are back with another update. Anyone else have this problem?
Mac mini, macOS 12.4
i also use my mac to mirror videos and such to my TV. i updated from 12.3.1 to 12.4 yesterday. after reading your question, i checked to see if i could still mirror to the TV. it is still working today. i think that in your situation, you should reset the mac's SMC as well as do a NVRAM / PRAM reset. please see these two apple support documents:

Resetting the SMC did the trick. Thank you!
you're welcome. i'm glad to hear that you've got it working again. :)
