I'm going to be buying one of these monitors, but before I do, I have a couple of questions. First, does the 2070NX use only S-IPS matrices and nothing else? I know that Dell and HP and maybe a few other manufacturers use the bait-and-switch tactic; does NEC do this? Second, I will be using the monitor for CAD, Photoshop, text, gaming, movies, and TV; what are the benefits of the 2090 over the 2070?
