My external display is noisy / has interferance.
I can't change refresh rate. It was working perefectly on previous MAC OSX
Also not able to watch netflix through Safari on external monitor - get an error about making sure my monitor is HDCP compliant and isnt mirrored using airplay (which it isnt). Error Code S7336
MacBook Pro with Touch Bar
Matt I had the exact same Netflix error code after upgrading. I had to switch from Safari to Chrome and then my streaming worked again!!
it works but not with highest resolution. Just capped at 720p HD only. Safari can ensure at least 1080p playback
Hi there, Matt_Gr,
Welcome to the Apple Support Communities!
We understand that your external monitor isn't displaying as you'd expect it to. We'd like to have you take a look at the troubleshooting steps outlined here to help isolate this behavior further: Get help with video issues on external displays connected to your Mac
If you're only seeing the error code S7336 while using Netflix, we'd recommend that you reach out to Netflix directly to investigate this further with you.
We hope this helps.
Cheers!
