Hi all. I'm ready to set up a new HTPC. I want to buy a mac mini and set it up on my Sony 4k tv. To get the cpu to run at 4k, what type of cords/adapters will I need? Will a high speed HDMI cable work? What other settings might I need to adjust to try to get the TV to operate at 4k and about 25 - 29 hrz?
