Cannot to my Epson dataprojector anymore.

Hello M3teachme,

Thank you for posting to Apple Support Communities.

We understand you're unable to connect to your your Mac to your projector. We're happy to offer a couple of suggestions.

Apple recently released macOS Ventura 13.3. Upgrading to this version may resolve the issue: Update macOS on Mac - Apple Support

We also recommend contacting the projector manufacturer as they may have additional steps that you can take: Contact a third-party vendor - Apple Support

That should help.

Take care.

Hi M3teachme,

That's great news. If you run into any other issues, you're invited to create a new thread so the community can assist once again. 

Have a great day.
