Apple TV videos suddenly blacked-out (with audio) during AirPlay
Up until a few days ago, neither my LG TV nor my Samsung TV had any issue AirPlaying video from my M1 Macbook Air. But suddenly, select streaming content displays as a blacked-out rectangle. Audio works fine, and everything else on screen is 1:1 with the laptop display.
I am using AirPlay to cast directly to the TVs, which, again, used to work just fine.
Here's a breakdown of my experience:
Apple TV+ shows via Apple TV App - Blacked out
Apple TV+ shows via Browser - Works
Xfinity Stream via Browser - Blacked out
YouTube via Browser - Works
It's just oddly inconsistent. Previously, everything displayed 1:1 whether I was mirroring or using either TV as a separate display. The fact that it suddenly stopped on two TV brands struck me as odd.
I've tried disconnecting and reconnecting airplay multiple times in succession. Video appears as normal on the laptop the instant I disconnect AirPlay. Everything else stays 1:1.
I am running Monterey 12.1. I'm unaware if the MacBook auto-updated since it last worked properly. Any suggestions? Thanks.
