I used to subscribe to the "60Hz is enough for anyone" idea, but after using a high refresh rate monitor for a while, I have to admit it does feel a lot nicer to work with. Even small things, like window animations, feel a lot smoother by just a 50% increase in frame rate. Even Apple has upgraded their mobile displays to surpass 60Hz. With gaming monitors now doing ludicrous things like 1440p@480fps, I don't think 5k@120fps would even be difficult for manufacturers. Stuffing everything over a DP 2.0 connection may be difficult, though, but DP 2.1 has been with us for a while now. 5k at 195fps (159fps with HDR enabled) can already be achieved with a standard DP 2.1 port. When it comes to displays, I think we're currently limited by GPUs rather than Displays. Nvidia's 40 series GPUs only come with DP 1.4, for instance. Until 2.1(b) gains wide support, it doesn't make any sense to build monitors that rely on it to do their job well.
