Why buy monitors (wide gamut 30", especially single input options) meant to be used with color managed programs then? Consumer media (games, movies, tv, web) does not use the Adobe RGB color space.
Come on man.
Most people see IPS and they assume it's a great monitor. Yes, it goes much deeper than that, but for most that's good enough.
I doubt some know the difference between e-IPS, S-IPS and H-IPS.
Options can get complicated and expensive very quickly if a person decides to get into professional color management monitors, NEC being the main vendor.
At that point, gaming performance is probably at the bottom of the needs list.
Most consumers want an all-around performer so high refresh rates, low input lag, and great colors are usually the general requirements.
Color gamut, 8 vs 10 bit color, various panel types and color profiles goes right over consumers heads.
