Question

I have the above flat screen TV and can see a space on the outside for connecting to a PC but it is blank. I took the back off the TV and can see that there is connection for a connector on the mother board for possibly a USB port or a small round pin connector, similar to the mouse connector (don't know what this is called). There is one of these for a VCR but don't know if this will suffice for the PC. I don't have a lead to connect this to the computer and don't know which of the sockets I should use. Can you help please?
