Display port would be the best choice. HDMI 1.3A and above should be able to do 1080p 144hz however not all monitors support 144hz over HDMI.
Unfortunately the GPU does not support Display Port. [strike]It also only has a mini-HDMI[/strike]. I'm assuming that DVI will be the way to go, but I'm not sure which cable to use, which I can connect to BOTH monitor and GPU, to utilize the 144Hz
I checked the wrong specs. The GPU does have 2 HDMI's, but I've read somewhere that:
1) HDMI only supports 60Hz
2) If 1 screen is only 60Hz, then both screens will be capped to 60Hz
HDMI itself is not limited to 60 Hz, but many monitors are, so people have misinterpreted this to think that HDMI is limited to 60 Hz but this is a myth. This is a limitation of those monitors, not a limitation of the HDMI standard. I have a monitor that supports 1080p 144 Hz over HDMI 1.4 personally (the XG2401).
The VG248QE supports 144 Hz over Dual-Link DVI and DisplayPort. It does not support 144 Hz over HDMI unfortunately.
There are no cheap passive adapters for connected to either DP or DL-DVI if your computer does not have either of those; if you are on a laptop or something with no DP output, then I would recommend against the VG248QE since you will not be able to run it at 144 Hz, and instead get the XG2401 since it can run 144 Hz over HDMI.
You can run 1 monitor at 144 Hz and 1 at 60 Hz, they do not need to be the same refresh rate. However if you are using an NVIDIA graphics card, if you play video on your 60 Hz monitor while gaming on the 144 Hz monitor, then the 144 Hz monitor will be capped to 60 Hz for the duration of the video.
