I have a late 2009 iMac i5 27" which I currently use for PS3 gaming (with Kanex XD), but I am considering adding a 2nd monitor for extra workspace (not that 27" isn't enough, I'm just spoiling myself at this point, lol) and so that I can plug my PS3 to that for 1080p (Kanex only allows 720), and if there are multiple people in the room one could use the iMac while others play games. Basically I want both the iMac and the PS3 inputting to the 2nd monitor (to be used at separate times of course). Before I buy a bunch of stuff I want to show my plan and check with you guys if it will work? Also I'm linking the products I am thinking of getting, but any words of warning or just other recommendations would really be appreciated. I've never had 2 screens and I don't want to buy all this junk and find out for myself it won't work. I figure I will need an HDMI switcher (so ps3 and imac both go to monitor), a MiniDisplay to HDMI output cable, the extra HDMI cable to connect from MiniDisplay cable to the switch box, and of course a monitor (which if i get that kind will need an hdmi to dvi adapter). After all this I would no longer need or have room for the Kanex XD and could sell it to help the cost quite a bit. edit: nevermind this part! And I have one other question... I have a set of speakers plugged into the 5mm jack on the iMac. If I'm playing PS3 on the second monitor, I'm assuming the audio will never output to the jack. The monitor I linked only has DVI and VGA input. How could I make sure audio works right? Or am I better off finding a different monitor? Thanks in advance for any advice, I really appreciate it!
