AOC Gaming U27G4R Launched with 27” 4K 160Hz IPS Panel and ‘Dual-frame’ Technology

AOC have introduced a new gaming monitor in their G4 series. The AOC Gaming U27G4R features a 27” sized ‘Fast-IPS’ LCD display with a 3840 x 2160 “4K”, a 160Hz native refresh rate and support for a “dual-frame” technology. This is AOC’s name for a fairly familiar “dual-mode” function we’ve seen on an increasing number of monitors over the last year or so. With the click of a button this feature allows users to drop down to a lower FHD 1080p resolution (1920 x 1080), and boost the refresh rate up to 320Hz. This is the first of its kind monitor in the AOC line-up and will appeal to gamers who regularly switch between immersive and fast based competitive play games.

AOC GAMING U27G4R Specs
The screen is 27” in size and built around a ‘Fast IPS’ panel. It offers a 3840 x 2160 “4K” resolution, a 163 PPI pixel density, a 1ms G2G response time spec, 1000:1 contrast ratio, 400 nits brightness (SDR), 178/178 viewing angles, 8-bit colour depth and a wide colour gamut covering 95.9% of the DCI-P3, 124.7% of the sRGB and 93.4% of the Adobe RGB colour spaces.
The high refresh rate is supported by adaptive-sync technology for VRR from compatible systems. Other gaming features include their G-Menu software, and various settings including Shadow Control, frame rate counter, Crosshairs and a Motion Blur Reduction mode (with 0.5ms MPRT spec).
The stand offers a full range of tilt, height, swivel and rotate adjustments
