Great buy I am also considering getting a 4k monitor and that is why I read your post with interest.
One curiosity...how do you feel about using two monitors with different resolutions? Is there any issue or not?
I have two 1080 monitors and the 4k monitor I would like to purchase would be the third one to put in the middle.
As for cables my situation is worse than yours :) !LOL
