A big screen monitor for gaming
Up to this point, there haven't been very many 4K computer monitors to get too excited about. Some of the early models use lower quality panels, while others have janky issues pumping out 4K Ultra HD at 60Hz. The technology is maturing, however, as evidenced by Acer's XB280HK, a 28-inch gaming monitor with a 3840x2160 resolution and support for Nvidia's G-Sync technology.
This is the first 4K monitor to support G-Sync , which synchronizes the display's refresh rates to the GPU to eliminate screen tearing, minimize display stutter, and reduce input lag. The end result is smoother, faster game play without having to tweak a bunch of settings.
Other features include 170/170 degree viewing angles (horizontal and vertical), DisplayPort input, four built-in USB 3.0 ports, LED backlight, and a multifunctional stand that supports tilt from -5 to 35 degrees, 120 degrees of rotation, 150mm of height adjustment, and pivot.
Acer didn't say how much it's asking for the XB280HK, though the company did say it will begin shipping the monitor in the second quarter of this year.
