Heads up to anyone who got a 2016 MacBook Pro and was thinking of connecting via USB-C port to the new LG 38UC99-W. It does not display any image despite being able to power the MacBook and have connected drives appear on the MacBook desktop. Just a black screen. LG offered no solution and simply said it should work via USB-C port. I was able to get the LG to display when using a display cable and USB-C to DisplayPort adapter. The adapter which shall remain nameless barely accomplished the job and the slightest of movement of the cable resulted in loss of display. I also a experienced a complete freeze of the MacBook while connected to the LG. I tried out a few different 34 inch LG models and concluded that a resolution of 3440 x 1400 has an appearance similar to that of my 8 year old Cinema Display. Given this experience I will not be gambling on the plastic, clunky looking LG 4k & 5k displays that are supposedly "made for the mac".
