You are chatting with Linda, an Apple Expert
Linda: Hi, my name is Linda. Welcome to Apple!
Me: Hello
Linda: How may I help you?
Me: Could I connect my Xbox 360 to one of the new 27" iMacs and use it to play games?
Linda: I am happy to help.
Linda: We do have a product called Elgato that will allow you to connect the game system to the iMac.
Linda: I can get you the link to do so.
Me: Right, I'm aware of that, as I know it's an option for my current mac.
However, the new 27" iMac says it supports video INPUT, as well as output?
Linda: That would be input via the mini display port.
Linda: The mini display port is available on our notebooks.
Me: Is there anyway to convert the HDMI out on my Xbox to the Mini Display Port format?
Linda: The input would be only for devices what have a mini display port.
Linda: Let me see if there is an adapter.
Me: It says on the Apple website: "supports input from external DisplayPort sources (requires cables and adapters, sold separately)"
Linda: I am looking to see if there is an adapter currently available.
Linda: Currently we offer a mini display port to mini display port cable.
Me: What about this?

Linda: Thanks for waiting. I'll be right with you.
Me: Sure.
Linda: That is for use on the prior models for output from a mini display port to HDMI on a TV or display.
Linda: It is also used on our notebooks to output to a TV.
Me: So it won't send signals the other way?
Linda: The input on the new 27 inch iMac is for devices that have a mini display port and we offer a mini display port to mini display port cable to do so.
Me: So no cable exists to get my HDMI cable to convert to a Mini Display Port one?
Linda: The input is for devices with a mini display port.
Me: So is it true that there's no way to get a HDMI source to display through the new iMac?
Linda: The input is minidisplay to minidisplay and we offer a cable to do so.
Me: So are you saying it can't be done? I just want a simple yes or no? Whether it can or not determines whether I purchase one so I really need to know for sure.
Linda: The input is mini display to minidisplay, there is not an adapter to convert HDMI to input to mini display.
Me: Will Apple release such a cable?
Linda: We are not able to speculate on the future.
Linda: The input is designed for minidisplay to minidisplay.
Me: That's a shame, I'm sure a lot of people would have loved the benefit of using it as an external display too - for non-apple products.
Linda: May I help with any other product or order questions before you proceed?
