TV as display not working after macOS 26

After upgrading to macOS 26 yesterday on my Mac Studio M1 Max, my display stopped working. I am using a 65" Vizio TV as a display and when I plug that same exact HDMI cord into a computer monitor it displays correctly. Any ideas on why this is not working? Thanks!


Mac Studio, macOS 26.0

As far as I know, Apple does not do much monitoring of these forums, except to moderate them. Occasionally, I have seen posts telling people to contact Apple Support directly, but that's about it.


There is the Product Feedback page:
