The LG 27GN800 features LG's own Nano IPS 10-bit panel with 2560x1440 resolution, 144Hz refresh rate, 1ms response time, 1000:1 contrast ratio, and 350nits of brightness. It also covers 99 percent of sRGB color gamut, it claims.
When it comes to inputs and outputs, you get two HDMI ports, one DisplayPort, and a 3.5mm audio-out jack. The LG 27GN800 comes with a standard stand, so you only get tilt adjustment, but it also supports a 100x100 VESA mount.
It wouldn't be a gaming monitor if it did not come with support for both G-Sync compatibility, as well as FreeSync Premium badge. So it does. There is also LG's own Dynamic Action Sync (DAS), which reduces input lag, as well as some other features like Black Stabilizer, Crosshair, blur reduction, and HDR support, it is claimed.
Unfortunately, LG didn't detai about price or the availability date for the LG 27GN800, but we will surely keep an eye out for this one.
