Alright so I have a Samsung P2250 monitor. I also have an Xbox 360 and a Gaming computer tower. I want to hook both up to the monitor but I don't have the cables necessary to do that. What will I need to buy to be able to hook everything up at the same time. Also keep in mind that I would like to have sound from the Xbox 360. Right now I have the Computer hooked up O.K., I just need to hook up the Xbox 360 as well. Is there some sort of switcher that is Something to RGBYW? or YWR? (Red Green Blue Yellow White and Yellow White Red.) Please help me! Edit: my computer has no built in speakers and It doesn't have an HDMI port.
