A refresh rate of 60Hz means new images are introduced at a rate of 60 per second. A 144hz gaming monitor is one where new images are introduced at a rate of 144 per second. Obviously, the faster images are introduced the smoother and clearer the action will appear to the brain. Industry standard as of this writing is 60Hz, which is more than sufficient for most desktop applications and things like 2D animated games. But for something like Deus Ex 60Hz just won’t provide the wealth of detail you need to be effective against top-flight competition. The higher refresh rate should make tracking easier and improve your ability to aim quickly and accurately as well.\r
