This is awful, don't use that. Simply looking at the specs of a monitor and saying "this one is 144hz and 1440p, this one is 4k and 60hz" is pointless. Look for people who know what they're talking about. And how do they know? Cuz they actually review monitors by doing extended and complex tests. For example, this is a great source if you're wondering what monitor to buy - http://bestmonitorsbyncx.createaforum.com/general-discussion/ , the guy is extremely knowledgeable about monitors, altho you should also make your own conclusions, like don't buy VA monitors for gaming, especially not for multiplayer where you'll have a disadvantage against other players, in single player it doesn't matter as much cuz the game will just be harder for you
