Hi w andersen,


Thanks for visiting Apple Support Communities.


If your TV is not recognized by your iMac when you connect it, I recommend the troubleshooting tips found in this article:


Apple computers: Troubleshooting issues with video on internal or external displays

Start with these steps:

Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:

Reset the system

You can reset the Mac's parameter RAM and SMC.

Best,


Jeremy
