Because I don’t have full sized display port?
I have HDMI, VGA, DVI and mini DisplayPort available. I got rid of my last regular DisplayPort screen after a thunderstorm .
My 2048x1536 CRT screen and 19” LCD is good enough for now.
Found it very strange that a pc even in 2014 had DVI as a primary option with a DisplayPort
It's just a joke.
