this is a real learning experience. I haven't tried it yet but the s-video connector on the PC is 7 pins (dell inspiron laptop) and the keystone connector I got is 4 pin. I don't own a tv with these connectors (VGA or S-Video)

But if the TV is also a 7 pin s-video will these 4 pin s-video keystone connectors work? will leaving out these 3 pins be a problem?
