The solution GIGABYTE is now supporting is to use dual Thunderbolt ports (which comply with DisplayPort 1.1 standards) to merge two 2K outputs into one 4K output. The twin Thunderbolt ports provide twin 10 Gbps connections which you can use to connect up to 12 total devices; however, a single 4K monitor is more impressive to me.
We have to just wait to see how the industry responds, because now I want to play my games on a single 4K monitor. The idea is expensive but should be great for those who need extreme resolution monitors in a professional capacity. I simply want to consolidate all of the wires for my system into a single daisy chain. Either way, GIGABYTE TH motherboards are the way to go.
