The world has yet to catch up. A couple of years ago I ran some HDMI cables from the media area to my projector and the scant faceplates available were amazingly poorly thought out. In the end I ran standard HDMI cables, got some keystone faceplates with blanking plates and some right-angled HDMI gender changers. Cut a hole in the blank and plastiwelded the gender changer into the hole. Actually worked and I even managed to get it inside a 25mm backbox*. Do like the idea of running it over Cat6 with a punchdown faceplate though.
