Actually , DisplayPort does have that technology . However , we run into slight problems here . First , the monitors have to support it , denoted by if they have MultiStream Transport , or MST . Secondly , the issue is that we are pushing a massive amount of pixels , the monitors 4 K 60 each need to have 1 . 5 gigabytes of data pushed to them per second . Now , each DisplayPort 1 . 4 cable can push about 4 gigabytes per second , so for one and even 2 4 K monitors , it is fine , but 3 is 4 . 5 GB per second , so too much . There is a way around this , a technology known as Display Stream Compression DSC , which cuts the amount of data needing to be pushed to the monitor by 23 , so it only needs half a gigabyte per second . However , once again , the monitor must support DSC , which it seems that very few do .
