    I am installing a long 12 m VGA cable in my lounge as part of a custom install for my projector. I am terminating the cable at both ends using a VGA face-plate. The wiring for the face plate doesn't have a connection for the cable screen. I rang the supplier who said this is not necessary to connect the screen. Given the length of the cable is this true? Should I connect the screen to the ground connection? Alternatively I could connect to screen to the house earth. Should I put ferrite cores on the cable?

    The specification for the face-plate that I have purchased is provided here:

    Thanks

    Connect the cable screen to one of the nuts of the VGA socket behind the face plate. That will sort it.

    Edit: I just had a closer look at the picture. There is a ground connection - GND. You can connect the screen to GND or like I said to the nut on the back of the VGA socket.
