Tell that to my school division’s IT department, who have us all running Displayport to VGA adapters, attaching to our monitors and projectors via VGA. This is because our displays are either a) too old and only support VGA and DVI in, or b) they purchased displays with HDMI, but our ThinkPad laptops only have Displayport out. Sometimes it is more a matter of mixing and matching tech in large cash-strapped systems that might get slapped by these issues as well. And yes, those adapters cause as many headaches as you might think.
