x-box 360 and pc through the same monitor I have the vga cable that I need to connect my 360 to my tft monitor and I'm happy with how it runs but I want to be able to switch between my pc and 360 without swapping the cables. Is this what I need (the top product in the link)? link Would I need an extra cable to connect the box to my monitor?Does anyone know the best place to buy these boxes cheers
