I keep an old PC for back up, & the monitor packed up! I've been given an old monitor, AST Vision 4i, that has no cable. My broken monitor had a built in cable, with 13 pins in a 15 pin plug, that would fit into my modern PC. My problem is the replacement monitor has a socket with 2 rows totalling 9 pins. Will I be able to buy a standard cable for it, please? Thanks, Al.
