So i've been searching around and found nothing about connecting a display that has bigger resolution than 1080p, but not 4k, like my Dell Ultrasharp u2713hm - via HDMI. Reason is that i have a few Thunderbolt devices which doesn't have two TB-ports and because of that i can't daisy chain them. This leaves me with my screen not connected because of those two TB devices that i have to have connected all the time. So, I've been reading up on connecting 4k displays via HDMI with a result of 4k resolution but with 30hz. How is it when connecting HDMI -> Displayport cable to the Dell Ultrasharp? Can i get full resolution at 2440x1440? Its on my rMBP 2012.
