macOS 13 Ventura BREAKS Panasonic TV connection via HDMI

I'm not having any issues mirroring my intel iMac (Ventura) to my TV.

I think in your case, I would try and reset the SMC as well as an NVRAM reset. please see these two apple support articles:

How to reset the SMC of your Mac - Apple Support

Reset NVRAM or PRAM on your Mac - Apple Support

Is your TV Panasonic? The problem is with such devices on Ventura.

sorry, no. my TV is a Samsung. the SMC and NVRAM resets can usually resolve issues with external displays for Intel Macs, which is why I suggested it. since it didn't work in your case, and also happens for others on similar TVs, it could be an issue on that end or with the Mac itself.

you may want to send apple some feedback. Feedback - macOS - Apple

Likewise. I’ve had the same issue with my Mac mini connected to my Panasonic TV. The only solution is to reboot every time. If I change the HDMI input on the TV, I have to reboot the mini with the correct HDMI input selected to get the mini to display. Extremely frustrating. Latest release of Ventura and 2020 intel Mac mini.

I have the same problem. have you find out the solution?

Thanks for the information. Which configuration(s) did you test?

Please indicate television name and model, macOS version and build, Mac model (Intel or Apple silicon; model Identifier and release date). When using Thunderbolt port? When using HDMI port? Using adapter? Which one? Apple USB-C Digital AV Multiport Adapter (link above)?

All such information is important to determine when the bug arises. Thanks again!

Since this is a Ventura bug, it is important to send feedback to Apple:

To Moderetor that edited my post above:

Thanks, but NO. Apple Feedback at

Product Feedback - Apple

is NOT the best place to send BUG reports. The best place is using the Apple Feedback Assistant at

https://feedbackassistant.apple.com

I do that all the time and Apple answers me, requesting information, etc. That way I have contributed to fixing many bugs in the past. Please, do NOT delete such Apple Assistant link. Thanks!

I have exactly the same problem, I bought a panasonic 4K 2023 TV to go with my I MAC and he doesn't see it. It drives me crazy. I also go through Thunderbolt in HDMI. He doesn't see, he doesn't see it, he doesn't see my panasonic 2023 TV please fix it. I am also on macOS 13 Ventura...help!!!

This problem has been breaking me for months, if anyone finds a fix please let me know.

The problem persists with macOS 13.4 (22F66) Ventura. As said, the issue arises with Intel Macs (not Apple silicon Macs). Some Macs cannot be upgraded beyond Ventura, so the only solution will be when Apple fixes this serious bug in Ventura.
