Big Sur 11.1 External Display Issues!

I've installed macOS Big Sur 11.1 right after it launched today. My mistake lol


Unfortunately, I noticed my Type-C ports no longer recognize my two external monitors. I'm using HDMI to Type-C. So far my troubleshooting is as follows:

  1. PRAM reset. This seemed to help until I locked the display. Once unlocked via Touch ID, the True Tone went off and one of the two monitors went out and will no longer connect. Woot. Normally, when connecting an external display, the screen goes black then back on, however, the screen short-of lags and then doesn't ever detect an active connection.
  2. SMC reset. This actually didn't help at all... :(
  3. Fresh install, same issues.


Any suggestions?
