macOS 13 Ventura BREAKS Panasonic TV connection via HDMI

macOS 13 Ventura BREAKS Panasonic TV connection via HDMI.

The "Apple - System Settings - Displays" shows the Built-in Display ONLY. The Panasonic Smart Viera TX-L47DT60E television (TV) is not shown, even after pressing the Option key and "Detect Displays". Nothing else is detected.

Is there a way to fix it, or is it a Ventura bug?

No problem with previous macOS versions, including Sierra, Big Sur or Monterey, in which such TV automatically showed in "Apple - System Preferences - Displays".

System: macOS 13.3 (22E252) Ventura on iMac 27-inch Retina 5K display 4.2 GHz Intel Core i7 7th-generation; model identifier iMac18,3 mid 2017) 40 GB RAM.

TO ADMINS: please, place the post below at the end of this thread (page 7) because it contains the SOLUTION. But each time that I post there on page 7, it shows on page 4. Thanks.

This post should be at the end of this thread and not here, but this forum automatically places it on page 4. So, I have deleted its contents. And after doing it it was placed on page 7. The original message was as follows (posted on page 7 but shows on page 4):

WOW, WOW, WOW!!!

I just cannot believe it. Amazing, fantastic, terrific!!!

Apple FIXED it with macOS 13.6.5 (22G621) Ventura. Note that you may need to switch from

01-Apple - Systen Settings - Displays - Use as - Extemded display (shows Panasonic-TV with black content) does NOT show Mac content on TV

to

02-Apple - Systen Settings - Displays - Use as - Mirror for Built-in Display (shows Panasonic-TV with Mac desktop picture content) displays Mac content on TV and then also option 01 above works

While playing Mac movie on TV it shows as

03-Apple - Systen Settings - Displays - Use as - Main display (shows Panasonic-TV with black content) while playing Mac movie on TV

Many thanks, Apple. When it seemed impossible, Apple listened and fixed it. Better later than never. YOU MADE MY DAY!!!

:-)

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.

FIXED (sort of). I followed the suggestions of Reddit user's https://www.reddit.com/user/mistakenotmy/ and tried buying and attaching to my HDMI dongle an EDID emulator like this one. The TV was identified straight-away and I can now use it with my Intel-based Ventura MacBook Pro. Yet another dongle, and I've read online there might be software-only hacks for this, but this is in the end a very straightforward fix. More info here.

Hope this helps!

HOLY SMOKES, THEY DID IT!

I just upgraded my 2019 Air (Intel i5) to Sonoma because of your question and my Panasonic TV was immediately detected. Who would've thought... I had always believed that there was something wrong with the TV until I found this thread (I was already on Ventura when I got the TV, so for me it never has worked before...).

I'd say just give it a shot and try upgrading. By the way, I do not use any original Apple USB C to HDMI adapter, just some rando generic one off of A****n.

Cheers.

NO. I do NOT keep on repeating the same thing. I do UPDATE the thread EACH time that a new macOS version is released. And yes, Apple listened and fixed it with macOS 13.6.5 (22G621) Ventura, as reported my my post today. So, all this effort was useful, contrary to what some thought.

I have the exact same problem, solved it by buying this thunderbolt to HDMI emulator of Amazon https://www.amazon.de/-/en/dp/B07YMTMMH5?ref=ppx_yo2ov_dt_b_product_details&th=1

Works like a charm, though I found it a little pricey at 20Euros.

The issue remains on macOS 13.6.3 (22G436) Ventura. Apple jumped to such update from the previous 13.6.1 (22G313), at least on Intel Macs.

Apple, please fix this serious problem on Intel Macs (no problem on Apple silicon ones) that arose with Ventura (no problem before) when connecting Macs to Panasonic televisions (which have HDMI ports), using the Apple USB-C Digital AV Multiport Adapter on Macs without HDMI port.

The problem also arose in the initial versions of macOS 14 Sonoma (the ones before the final release and which I cannot name here because then the robot removes the message thinking that it is subject of a developer forum, but it is not; hint: second letter of Greek alphabet).

Apple noticed such issue and fixed it but only in Sonoma; not in Ventura. So, Apple knows about this serious bug and could fix it in Ventura as well, as done in Sonoma. A few Ventura updates remain, so there is time to fix it, but not much. Thanks!

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.

Thanks Barney-15E, but that does not fix it, since the Panasonic TV software was already updated. For instance, Panasonic TV system software version 3885-10502 for Panasonic TX-L47DT60E. As shown at

Panasonic TV: How to Update

https://www.youtube.com/watch?v=kYx9MeoWdV8

that redirects to Panasonic web site at

Digital AV Support > TV

https://av.jpn.support.panasonic.com/support/global/cs/tv

In summary, this is a bug generated by macOS Ventura (no problem before) on Intel Macs (no problem with Apple silicon ones) on Panasonic televisions (no problem with other manufacturers) at least on Macs like iMac that do not have HDMI port and require "Apple USB-C Digital AV Multiport Adapter”https://www.apple.com/shop/product/MUF82AM/A/usb-c-digital-av-multiport-adapter. Indeed, no problem when booting from other disk or a disk partition with macOS prior to Ventura. THIS IS A VENTURA BUG.

Only Apple can fix it. Hopefully, they will do it in the next macOS Ventura update, because it will be the last one (besides security ones) and some Macs cannot be upgraded beyond Ventura. Is Apple listening? Thanks!

That's not what I was talking about. There are various versions of HDMI. Some TVs have the ability through the onscreen menu system to change the HDMI version used.

No. As said, no problem before. It arose with Ventura and only for Intel Macs (no problem with Apple silicon ones). It is a Ventura bug.

You keep repeating that as though it matters to us. We can't do anything about Apple bugs or Panasonic firmware.

All we can offer is things to try to workaround the issue.

If it is a Ventura bug, revert back to Monterey or earlier, if possible. Perhaps it will work in Sonoma, but nobody here would be able to say if it does.

I have seen other post were changing the version of HDMI used by the TV in its on screen menu as helped other people with different TVs. Is there such a setting in the Panasonic TV?

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:
