Microcenter sells one @ $399 with the same warranty but has DVI/HDMI/VGA/DisplayPort. I'm assuming same panel as it is also IPS LED.

No, according to your link Microcenter is selling with a one year warranty. The OP article indicates Monoprice will use a three year warranty.
I wonder how likely a monitor like this is to fail in year two or three.
(Note that I didn't downvote, I'm just giving a plausible explanation as to why someone might.)
> As you've come to expect from Monoprice, we stand behind our products and offer a full 1 year warranty, which is at least 3-4 times what is offered by other monitor manufacturers.
