That should not be 5k2k, but rather Dual QHD. LG also calls it UWDQHD.
5k2k should be arround 5.120 x 2.160 pixel.
This is not 5K x 2K as that is 5120 x 2160. 5120 x 1440 is known as DQHD or dual quad HD which is 2560 x 1440
What kind of BS is this?? 5k2k is 2160 vertical! I got all excited when I read the title, only to be disappointed. I guess we are all waiting for the LG's 45" bendable one from CES.
