I have recently purchased a S-video cable so that i can watch videos from my laptop on my TV. My laptop (Samsung V25) has a S-Video socket on the side and my television also has a S-Video socket. What I have tried is to plug the cable into each and then toggle the function F4 key to change it from different monitors. However, this does not work and no image is picked up on any AV channel. It does flash for a second on the TV, which shows it does recognise something. In the display settings it only recognises one monitor and i have no option of selecting a secondary monitor. If any of you can help i would be very grateful. Thanks in advance.
