Well, now I feel pretty stupid. I should have included a lot more information in the original post, but I have things figured out now.
Current monitors
Dell s2716dg
Asus vg248qe
The Dell supports HDMI 2.0 and Display Port 1.4 so I am having no problems as of now getting the fullest from this monitor.
The Asus supports Dual Link DVI-D, Display Port 1.4, and HDMI 1.4, so my only options to reach 144hz are with dvi-d and dp 1.4.
As of right now, the Dell is working great, but my asus is running at 60hz and I'm rather let down that my gpu only has one dp 1.4. If anyone has any other ideas, I'm all ears. Otherwise, I plan on selling the Asus and getting a nice IPS display.
