There were numerous reports of the Ultra Viewing Angle coating coming off from the Pannel (if not handled carefully). Probably this is what forced them to experiment with ADS pannel. Whatever I read, it appears that it's a solid middle ground with IPS and VA Panel. With more dimming zones and intelligent algorithms, it can easily match the VA's contrast level if not higher at the same time offering a wide viewing angle (178 degrees). It's a step in the right direction.
