That resolution only makes sense for wall displays, but a display port could drive one such.
This drive for higher resolution resembles the similar drive for digital cameras, where resolutions on most cameras are now much higher than the accuracy of the lenses. What is needed for digital cameras is better light sensitivity instead.
On a laptop or tablet screen 4K is more than enough (3K is IMO the useful limit for less than 17" screens). Like in cameras, what is needed is not more pixels. On screens what is needed is better colour reproduction and better visibility is sunlight. Reflected-light screens (like Qualcomm's Mirasol, once fully developed) may be the future.
