Select "Screen Share" on the main menu then "Delete Pairing History". The first time you connect it will ask to "Accept" the connection and stores the Pairing History but for some computers the the second time you try to connect it fails possibly due to the way the Pairing History was stored on the LG TV. This only occurs for some computers, not others, indicating there may be some issue with the code written to store Pairing History on the LG TV so you must delete the Pairing History to get that computer to connect again. P.S. I work for the company that invented Bluetooth.
