The AOC U27G4F monitor features a 27-inch Fast IPS panel with two refresh rate modes: 4K at 190Hz and Full HD at 380Hz. This combination provides high image sharpness, smooth motion and minimal response latency — 1ms GtG and 0.3ms MPRT. The monitor supports Adaptive-Sync technology to prevent frame gaps and is VESA DisplayHDR 400 certified with a peak brightness of 450 nits.
The panel has a contrast ratio of 1000:1 and viewing angles — 178 degrees. The 10-bit matrix covers 99% of the sRGB color space and 95% of DCI-P3, with factory calibration ensuring color accuracy with a ΔE error of less than 2. A built-in six-axis color adjustment system allows for fine-tuning, and each monitor comes with an individual calibration report.
Features that enhance the gaming experience for gamers include AI-based dynamic aiming, sniper zoom, FPS counter, and a visual engine that adjusts brightness and contrast in real-time. MBR Sync and Dark Boost technologies enhance image sharpness and shadow detail.
The monitor features two HDMI 2.1 ports and two DisplayPort 1.4 ports, enabling 4K 120Hz output with HDR and VRR support on PlayStation 5 and Xbox Series X consoles. There’s also a 3.5mm headphone jack, but there are no built-in speakers.
