      That kind of makes sense though. I figure they assume you’ll have one computer hooked up and then a bunch of consumer devices that all use HDMI. And if you need a second computer hooked up you can also use HDMI if needed. Probably makes the most sense to the most people as having more DP in place of HDMI would just mean the average user couldn’t hook up as many devices since (almost?) no consumer devices use DP unfortunately.
