Hi there I have an DVI-I output in my computer and want to hook it up to my old TV. My TV Has a DVI input but i dont have a DVI-DVI cable i do however have a DVI-VGA cable and an adapter (VGA-DVI-A). So i can hook up my pc and TV but the TV doesn't show any picture... My computer however registers 2 screens (3 in total with my computer screen). Anyone stumbled upon this before and if so how to fix it?
