Hello MacRumors! Purchased a 2015 Retina MBP 13 inch - my first macbook pro and first computer capable of driving a 4K monitor. I'm new to 4K displays - been using an old 1080p monitor for the last 5 years. From what I understand this new macbook pro 13 can drive a 60 hz 4K display with the display port (this is the same as the thunder port slot?) What if the 4K monitor doesn't have a display port? I was looking at the back of some of the larger 4K TVs from Samsung and didn't see a display port in the back (Or didn't recognize it at least) Only HDMI? Can I use a thunder port to hdmi adaptor to get 60z? Very confused to all this. Essentially is there anyway to achieve 60hz with my MBP 13 2015 on something like this: http://www.amazon.com/Samsung-UN55H...&ie=UTF8&qid=1429468942&sr=1-2&keywords=4K+tv ?
