Came from a computer shop - needed it for the second input on my old viewsonic monitor - one end has a VGA plug, the other has 5 BNC plugs - RGB and H and V sync
I just got 3 adatprs that take the BNC to an RCA and slapped them on the end of it, worked. I just pluged it in, saw it worked in 480p and then unplugged it, I havent got the TV that will be going in the cabinet yet. Seemed to be as expected when I tried it. Didnt try adjusting for overscan etc
