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.

Hi hauke_99, thanks for the information. Sometimes such problem can be fixed unplugging and plugging back the connectors (make sure they are all well fit), as well as turning on and of the television and rebooting the Mac. If it does not work, maybe you received a defective emulator. If it works, please let us know if the TV color is pale (see above).

The issue persists with macOS 13.6.1 (22G313) Ventura on Intel Macs without HDMI port.


The issue remained in macOS 14 Sonoma before FINAL (I cannot say the exact word here because then the robot deletes this message), but as reported above, Apple fixed it in macOS 14 Sonoma FINAL, but not in Ventura. And some Macs cannot be upgraded beyond Ventura.


So, Apple generated the issue in Ventura (no problem before) and now does not fix it. Will Apple fix this? Is Apple listening?

Thanks, John Hawkins2. That confirms that Apple has fixed it in macOS 14 Sonoma (it was NOT fixed in the first betas of Sonoma). Albeit the problem is some Intel Macs without HDMI ports cannot be upgraded to Sonoma. Is Apple listening? Will Apple fix this bug that Apple generated in macOS 13 Ventura? (no problem before).
