My experience with the official dock has been quite negative, it would sometimes not work until the power cable is unplugged and then plugged back - that is with all the latest stable updates for everything. Other people on Steam forums run into this issue too.
I already have several others but wanted the officoal one since it has DisplayPort. Hopefully I don't run into the same issues, but I know now there are third party options with it as well.
That's too bad. I guess I'll 3D print something to hold the deck and just buy an Anker dock instead. I've been only playing handheld for now, but it would be fun to hook it up to my TV at some point.
