27" AOC G2790PX gaming monitor performance benchmarks: response, input and full specs review

The AOC G2790PX is a relatively new monitor. The monitor has a VESA mount. The AOC G2790PX has the Display Port and this is essential for NVIDIA cards to work with AMD FreeSync. With the AMD FreeSync support, this monitor is compatible with both AMD and NVIDIA graphics cards. AOC G2790PX has a total input lag of 13.5 ms, which is excellent among the competition. To compensate for graphically demanding games, the AOC G2790PX has a very good low end adaptive refresh rate of 30 Hz that can adapt to more lower frame rate drops. For the average response rate, the AOC G2790PX scores 5 ms, which ensures effective synchronization with the high refresh rate. The brightness of AOC G2790PX is significantly better than other monitors. The minimum response rate of AOC G2790PX is 1 ms, which is eliminates ghosting effects. For the extremely fast frame rates, the AOC G2790PX has a maximum refresh rate of 144 Hz that allows smoother gameplay. The monitor uses a TN panel which suffers from color shifting when viewed from horizontal and vertical angles and has slightly washed colors compared to IPS and VA panels. The monitor has an unimpressive contrast ratio of 1000 : 1. For graphics color quality, the AOC G2790PX has an average color depth of 6 -bit, resulting in dithered gradients and more slightly less accurate colors. In terms of pixel density, the AOC G2790PX has an low density of 81 pixels-per-inch, resulting in pixelated text and picture quality.

[SOLVED] Does G-SYNC work with AOC G2790PX? (25" model works)
Ok so since nvidia gave a list of 12 FreeSync monitors that are compatible with G-SYNC and one of them is AOC G2590FX (25", 144Hz, TN). I need to know does anyone own the 27" model AOC G2790PX and how does it work with G-SYNC.
