Modetest can see the new "force output format" property, but it's being rejected and falls back to RGB. I verified my EDID has support for YCC 420. Can you tell me how you're testing this change?

I tested this using wlroots with these changes applied:

N.b. there are instructions on how to reply to threads on
lore.kernel.org. For the original thread, instructions are on the
bottom of this page:

It's needed for bookkeeping on lore.kernel.org and it's useful for
recipients who will otherwise have to search through their email to
find the context.
