The ViewSonic VX2770 costs 300-320$ here (Canada) and the LG IPS277L is 350$+, no idea how much the Asus will be, but Asus models have the most adjustable overdrive settings.
One thing that is really annoying about these slim bezel'd IPS is that the inner black bezel border is such a deep black it makes the displays black levels always look light and stand out, the dell S2740L has the same issue too. I don't have a picture of my ViewSonic's bezel yet but I have an S2740L example:
Look at the letterbox bars
The effect is far less pronounced on the Asus/LG/ViewSonic/AOC, but still distracting, especially during letter box movies. It's too bad too because these displays typically have 1000-1200:1 contrast ratios and outclass most TN's and other IPS/PLS in terms of black levels.
Svete hardware has a review and the measured the pixel response times properly with an oscilloscope, ignore digital versus response time+input lag sections, they use outdated methods.
Svete hardware used the HDMI port with a Nvidia card, unless certain custom drivers are installed or the Ycbcr setting is used in the nividia control panel, the contrast,black levels will be terrible, which is evident in their review given the measured 280:1 contrast.Edited by MenacingTuba - 12/30/12 at 8:12pm
