the pig tale is glued on the back so pluging in an HDMI cable to it may push it out of the wall plate; mine poped out when I was installing it on the wall The provide screws don't make much sence to me.
Merchant Response:The 2 sets of included screws are for attaching the inner wall plate to the outer wall plate, and then attaching the entire wall plate to the box. Generally, you would secure the HDMI cable inside the wall, which would also prevent it from falling out of any wall-plate, and in this instance, having both HDMI cables plugged in, would prevent either side from moving. If it's not working out for you, then the best thing would be to bring it in for a refund, or mail it back to us !!
