Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
NO, this will not work. The connections you are using there are backwards.
The port on the printer is an OUTPUT, for use with an external monitor. It is not a video capture port, and the mac is not capable of displaying external content that way.
For that to work, you'd need an actual video capture device, which really doesn't work via hdmi anyway because of copy protection reasons.
Would you like some help with finding a video capture card/adapter that could accomplish this?
You're very welcome, Selwyn.
If you have any other questions, just let me know. Otherwise, please rate my service; hopefully I have earned 5 Stars. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh
