macOS 13 Ventura BREAKS Panasonic TV connection via HDMI

I have since reported the issue directly to Panasonic, and then spent a long while yesterday on the chat and phone to Apple using Applecare which we still have active. I was able to demonstrate on video the TV mirroring perfectly on our Mojave partition and on another Mac running on Monterey and then not working at all with the same cable and connection on Ventura. None of the suggested fixes solved the problem as expected given what many have tried already. I highlighted the Apple Community discussion and felt the technicians very much understood the problem. There was an indication that Apple would discuss with Panasonic so here's hoping.

Cheers.

UPDATE:

The issue remains with macOS 13.6.4 (22G513) Ventura on Mac (Intel) with Panasonic TV. Apple, please fix it. No problem before Ventura and Sonoma also fixed it, but some Macs cannot be upgraded beyond Ventura. Please, please, please!!! Thanks!

Perhaps it is because you keep repeating the same thing which doesn't provide any sort of technical support to anyone.

You keep pleading to Apple, but Apple doesn't monitor this community for anything but violations of the terms of use. You should contact Apple to express your desires for them. None of us here can do anything about the problem nor can we effect any changes with Apple or their products.

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

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!

Request to Panasonic (Belgium) sent!

#Incident: ****

”Dear,

for about several months, many users of a Panasonic such as me, of a TV and Mac under Ventura 13.5 computers are experiencing no image displayed at all.

See:

macOS 13 Ventura BREAKS Panasonic TV conn… - Apple Community

My TV runs the latest update. Ver.3.1222

Apple seems on the other hand reluctant to find a workaround to Ventura users. Therefore could you please ask Panasonic headquarters for the technical specifications of my TV regarding these very important points:

-Supported DisplayPort versions;

-Supported refresh rates and screen resolutions;

-Support of DisplayPort Alt modus;

-Any other relevant information regarding the communication happening through HDMI between a computer and this TV.

Best regards, and thank you for your cooperation,

Nicolas L.”

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 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!!!
