Q

Anyone experience that it only plugin with the display face down?

A
  • Mine plugged in face up on one laptop, but face down on the other. It depends upon what you are plugging it into. There is no standard for this.

    Edit - I feel stupid all the scratches were on a clear screen protector. I just peeled it off and the screen is not scratched at all. This unit arrived today on time. When i opened it looked well packed so either this unit was scratched at the factory or I was sold a used item. See the pictures all the scratches both front and back. It works fine, I connected it to my laptop via Bluetooth everything works as it should. Just cosmetically it's a disaster.
