Hi, I'm thinking of upgrading PC with a B850M Steel Legend, or Pro RS motherboard and Ryzen 9 7900 combo.

I have a sony mobile display that I'd like to use with my PC - do either of these motherboards support displayport alt mode over USB-C?

Many thanks!

Dear teegee21,
Thank you for the posting.

For this case, both B850M Steel Legend WiFi and B850M Pro RS do not support DP Alt Mode.

Thank you

Yours truly,
