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
I actually can't use a different cable, because it is embedded in the wall/attic... If the same cable worked for the previous five years, and it still currently works with a computer monitor [plugged into the exact same end] then it has to be some sort of a bug or software issue, right?
Only other thing that I can think of to try, is a USB-C to HDMI adapter.
for some examples:
USB-C Digital AV Multiport Adapter - Apple

Well, I would like a solution to use the hardware that I already have purchased and has been working. Buying a bunch of new cables/etc just to see if they work is not a realistic answer.
Do you all think that the Apple developers monitor this 'community' to see what bugs need fixing? :)

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:
Test a different HDMI cable.
Preferable the shortest possible, Certified Ultra High Speed 8K HDMI cable.
