Can no longer use streaming services (including TV app) on LG Ultrafine 5k attached to M1 MBP??
I'm increasingly being told by all streaming services that there is an "error" with playback when I have my MacBook Pro connected to my LG Ultrafine 5K monitor with the included LG USB-C cable. These are services I've watched with this same setup for years without a problem. But, now one after the other is not allowing playing on secondary monitor. All works fine on the built-in 16" MBP screen.
As of this week on Apple's own TV app, I'm now getting the "This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection)" message. I bought this monitor from Apple in part due to their gushing comments about this as the ideal monitor for Apple products, and now I cannot even watch my Apple content on the monitor.
I hope I'm missing a easy solution... I've tried a different thunderbolt 3 cable that both charges the MBP and displays the content on the LG screen, and get the same results. Is there a fix for this nonsense?
