I know its odd to say this but a lot of the specs on a monitor just really don't mean anything. A lower response time is better, as is a higher contrast ratio, but sinces there's no real standard which all companies use it's tough to tell which monitor is better simply by looking at the specs. The real specs which are useful are resolution, size (obviously), and panel and backlight type.
I'd take a look at the Asus VS238H-P, which is what I ended up getting after doing a lot of research (despite what the amazon headline says it does not have integrated speakers.
It has HDMI and DVI in, tilt on the stand which is pretty decent (the majority of complaints are a flimsy stand, but I don't have an issue with it). Its got a fast response time, nice colors after some calibration, and the LED backlight makes for a slimmer monitor with lower power consumption. As for the panel type (which i mentioned but didn't explain), its is a TN panel which is considered better for gaming (and cheaper), as opposed to the more expensive IPS panel which I would recommend for someone looking to do a lot of professional work that requires accurate colors.
Would definitely recommend this monitor. http://www.amazon.com/gp/product/B005BZNEVQ
