Have you googled for "vdpau display vout display error"? I'm asking,
because you didn't mention what exactly you already have done, to pin
down the culprit. Don't read just Arch related posts, consider to also
read e.g. Ubuntu related posts, if Arch related posts shouldn't cover
this issue for the same graphics.
Have you e.g. ensured that regarding the driver everything is ok?

/var/log/pacman.log helps you to search for packages that might have to
do with the issue.
