Got my iMac today, working great, but need help on how to hook up a TV to my system. Because my iMac is hooked up to the ACD 24" display, so the extra mini dvi port is occupied by the ACD, so then how do I hook up my 37" LCD TV to the iMac, so I essentially have three monitors hooked up to my iMac. The ACD plugs into the iMac no problems of course, but my TV will be a different story, it's has two HDMI ports, S video and the 3 rca inputs. Is there a splitter or something I can buy so I can add the TV to the set up. I've seen photo's here on this forum with 3 even 4 monitors hooked up, but I have no idea how to do it, searched here for a while as well. Does anyone know exactly what adapters I need to buy to get the TV hooked into my dual monitor system?
