Year by year, the world is migrating from 1080p. 1440p is now become the sweet spot even for mid-range graphics cards. Even consoles are making a break for the 4K horizon, courtesy of the PS4 Pro and Microsoft's Project Scorpio.
But if you want to purchase a 4K monitor today, it's not enough to do it for gaming. There has to be a productivity benefit. So over the last few months, I've been using one of LG's latest 4K monitors - the 27UD88-W, a $900 4K monitor with an IPS panel, FreeSync and a very versatile USB-C port.
