What better features might a higher end monitor have? How about I start with the most important one - the monitor panel :O IPS,TN,TL - color accuracy and gamut, glossy vs matte coating, color bit depth, resolution................not enough? There's more! The overall build quality - using cheap plastics or some premium ones? The list goes on, I am guessing you've never cared about monitors, have you? A good monitor for one person is bad for the other. Too many factors, caring solely about hz is not simply wise.
