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

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!!!

Indeed, macOS 14 Sonoma just announced yesterday will not support some Intel Macs, including the ones indicated above. So, Apple should fix this serious issue in Ventura, since such Macs cannot be further upgraded. Is Apple listening?

This is just too bad, Apple! In the future I will think twice about buying products from a company like Apple which simply decides to make your expensive up-to-date (!) periphery unusable without any discernible reason. I used Panasonic TVs as screens both in our department as well as at home. What to do now? Talking about sustainability...

Does anybody by any chance know any workarounds – perhaps an interface (in the form of a small box?) which one could interpose between our Intel-Ventura-Macs and the Panasonic TVs?

That being the case, the problem is Panasonic has not made their product compatible with Ventura. It's their responsibility to do that. Ventura apparently revealed a existing deficiency in Panasonic, but retro compatibility solutions may be impossible.

Unfortunately, a fix by Panasonic may not be coming. I use to get periodic firmware updates for our Samsung TV but it's age has stopped that. It remains to be seen if Panasonic can do that or if they will

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.

Hi steakkini, many thanks for the information! I understand that your 2019 Air (Intel i5) does not have HDMI port and that you connected the HDMI adapter to the Thunderbolt port. Which adapter did you use? What Panasonic model do you have? Thanks again for all.

Oct 7, 2023 12:37 AM in response to ApMaX

Hi ApMax,

sorry I mixed things up, it's an 2018 Air (A1932), not a 2019. It has the Dual-Core i5 1,6 GHz with Intel UHD Graphics 617 and only Thunderbolt Ports, no dedicated HDMI. The TV is a Panasonic TX-50JX800 and the adapter I use is a "uni USB-C to HDMI Adapter 4K 60Hz", which is available on Amazon DE and COM. Really nothing special but before upgrading to Sonoma I had to use a Dell Dock when I wanted to use this TV because none of the adapters I had at hand wanted to work (I also tried my brother's original Apple dongle (the USB C -- to --> HDMI, USB A, USB C one)).

Hope this helps :)

Thanks, steakkini. I understand that you mean the "uni USB-C to HDMI Adapter 4K 60Hz" at

https://www.amazon.com/uni-USB-C-HDMI-Adapter-60Hz/dp/B0CGTL5WZ4

On the other hand, did you mean that the Dell Dock worked to connect the Panasonic TV to the Mac with macOS 13 Ventura? Which one is such Dock?

Tried the trick with the EDID emulator – and it works for about 10 secs with my Intel-mac (MacbookPro 2019), then the TV screen turns black and remains black. Have not the slightest idea why. Can anybody help? Otherwise, I guess I will be forced to update to Sonoma, which surely will mean that something else is not working any longer...

Hi hauke_99, which configuration did you use? Please indicate:

Mac (Apple - About This Mac - More Info - System Report - Hardware - Model Identifier).
Does the Mac have HDMI port?
macOS , including version and build (Apple - About This Mac - macOS; click over version to show build).
Manufacturer and model of EDID emulator. Link most appreciated.
Manufacturer and model of television.
Adapter (if used)
Connection used, which I guess would be "Thunderbolt 3 port of Mac - Adapter - Emulator - HDMI cable - HDMI port of television"

Thanks!

Oct 19, 2023 3:16 AM in response to ApMaX

Hello ApMax

yes I did and my MBP intel (2019) now works perfectly just as it did with Monterey. I use a non-Apple HDMI adapter and actually bought an Apple equivalent, neither of which works with Ventura. Despite a visit to the Genius Bar (where they showed me the hdmi working on an external display (not Panasonic of course) I tried the upgrade as a last ditch effort and happy that I did.

i hope this works equally well for all other Mac/Panasonic users out there.

Hi kostaszag, thanks for the information. Is the color fine in the TV using such "EVanlak HDMI Emulator Adapter (3rd Generation)", or is it too pale? I ask because others have reported such pale color issue when using it.

Hi ApMaX, would be great if these informations could prove to be helpful:

– MacBookPro16,2 – Quad-Core Intel Core i5

– no, just 4 USB/Thunderbolt ports

– Ventura 13.5.2 (22G91)

– EVanlak HDMI-Emulator-Adapter (3. generation), compatible with Mac Thunderbolt auf HDMI-Switches/Extender/AV-Receiver/Video-Splitter, 1080 x 1920 bei 60 Hz (from Amazon)

– Panasonic, do not know model, but was bought around two years ago and worked fine with a Mac as long as I had not updated to Ventura

– yes, exactly: Thunderbolt 3 port of Mac - Adapter - Emulator - HDMI cable - HDMI port of television

Thanks for any support to solve this problem!

Oct 21, 2023 3:24 AM in response to ApMaX

I am not sure if the colours are paler or not, as I don't use the iMac for serious viewing, just the occasional YouTube video. The picture quality of the iMac playing videos on the TV has never been stelar anyway.

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.
