The official steam deck dock seems to be fairly buggy, it's widely complained about. I've been using an Apple USB-C to HDMI adapter and it's worked perfect on every TV I've tried it on. Since the steam machines don't use USB-C video out this wouldn't be an issue.

That may be the case but “official valve hardware is buggy even after almost 4 years” is a troubling yet true statement when their entire pitch today was literally “check out our new hardware.”

I love my deck. But a smooth experience it is not. Up until idk a year ago…? Flipping from gaming mode to desktop mode or vice versa had a solid 50-50 shot of inducing a fail state requiring a hard reset.
