BENQ Dual Monitor - Blurry w/ HDMI, works with DVI

I used to have a GTX760 which had 2x DVI outputs and both monitors ran great. Recently I got an office PC that is an upgrade (GTX960 on this one), but only has 1 DVI output, and then displayports and HDMI. I installed my secondary monitor with HDMI and now it's blurry (nothing like the main one or before when it was through DVI). It's very noticable on text. We've gone through the settings on the monitor and they haven't changed from before. Tried a few different things with the sharpness and it didn't help. Been Googling for a bit but couldn't find anything that helped me. What's interesting is they both look to be pixel perfect but the black looks weird compared to the other one. All text looks blurry, not sure if this is the same thing or what. Attached pictures: From the good monitor (XL2411Z w/ DVI): http://i.imgur.com/84aPbW8.jpg The bad monitor (XL2410T w/ HDMI): http://i.imgur.com/NwrfmVA.jpg My OS is Windows 8.1 Pro. I am not sure what to do here and would appreciate some help. Thanks in advance.

It's digital, so an issue with the cable can't be the reason for strange quality (at least that's what I always thought). When looking at your photos, the resolution seems to be the same as you can count the pixels and everything fits when comparing, so everything about that is fine.

You should default to displayport and use dual link dvi as a backup. Also you have to manually set in the nvidia driver that you want HDMI to be 0-255 color and not squished to like 16-235, that applies to everything output to the screen (unlike other outputs where you only have to manually set it on every driver update for video playing). You should avoid HDMI wherever possible though.
