Mac Projector Issue : Here are a few things you can try to troubleshoot the issue:
Make sure that the projector is properly connected to your computer. Double-check the cable connections to ensure that everything is plugged in securely.
Check that the projector is turned on and set to the correct input. Many projectors have multiple inputs, so make sure that you’ve selected the input that corresponds to the port you’re using on your computer.
Adjust your display settings on Ventura OS. Go to “Settings” and then “Display” to make sure that your computer is detecting the projector. You may need to adjust the resolution or other settings to get everything to display properly.
Update your graphics drivers. Outdated drivers can cause compatibility issues with projectors and other external displays. Check your computer manufacturer’s website for the latest driver updates.
Try using a different cable or a different port on your computer. Sometimes cables or ports can become damaged or defective, so switching things up could help resolve the issue.
