AOC has released G2770PQU which is a gaming focused 27 inch monitor with an excellent refresh rate of 144 Hz. It packs full HD resolution 1920×1080 and full 3D support. The AOC G2770PQU has response time of 1 ms and 300 cd/m2 brightness levels.
However G2770PQU is plagued by narrow viewing angles and mere FHD resolution because these days FHD is no longer considered top of the line.
There are four input ports that include Display Port, HDMI, D-Sub and DVI. It supports height adjustment and can swivel too.
The price is 419 Euros / $567 and will go on sale by the end of June 2014.
