The Acer Predator XB270HU is the most technically impressive monitor we've ever seen. A 144Hz refresh rate IPS-like panel was a dream even a couple of years ago, and now it's here as a very expensive reality. Our only real hangup with this monitor is its lack of inputs. A single DisplayPort in this day and age is a serious compromise, and while we understand the technical limitation imposed by Nvidia, we certainly don't agree with it. If you can look past this, though, this is a cracking gaming monitor.
