ASUS pn51-e1 Configuration

This was the first computer we used to support 4K. It's a fine computer but is a little finicky in it's set up

This would affect machines with serial numbers between KQ1168-KQ1182

USB Ports

The front ports of the computer are incompatible with the RIO board. This has been known to create poor performance in the game. Make sure that the RIO board is plugged into USB ports on the back of the computer.
