Ok so heres mysetup. 27inch 2010 2.93 i7imac (NO TB PORT) Gaming PC 24 monitor for xbox and Secondary display for the Imac. OK heres the deal. When i game on my gaming pc i would like to hook it up to the 27inch imac's display using "Target display mode". Please note that my video card on my gaming PC has a Mini display port (amd 6870). Now seeing that i dont have a mini display port to minidisplay port cable that i would need to get "Target display mode to work" Apple doesnt sell them online or in store anymore, checked best buy too. OK so heres my proposed work around until i order the needed cable. I have a Mini display to hdmi cable i purchased today and i was thinking what if i installed windows 7 on my imac via boot camp and tried the cable while in Win7, because the MDP to HDMI cable does not work under OSX 10.6.8 (have lion just havent gotten around to installing it) thoughts???
