AOC CQ27G4 27 Inch 2K QHD 180Hz VA Panel 124% SRGB 0.5MS Adaptive Sync Gaming Monitor

The AOC CQ27G4 is a 27-inch curved gaming monitor built around a VA panel delivering a 2560 × 1440 (QHD) resolution with a native 180 Hz refresh rate. Its curved screen geometry creates a wider perceived field of view, keeping gameplay centred and reducing the need to pan your eyes across a flat surface. Colour performance is a standout attribute of the CQ27G4. The panel covers 124% of the sRGB colour space, 121% of NTSC, and 101% of DCI-P3, producing rich, saturated visuals that benefit both competitive players and those who work with colour-intensive content such as photo editing or video review. Colour accuracy is rated at Delta E below 2, and the display renders 16.7 million colours. HDR10 support adds wider dynamic range to compatible content, extending the range of brightness and shadow detail beyond standard dynamic range monitors. For competitive gaming, the CQ27G4 delivers a 0.5 ms MPRT pixel response time, reducing motion blur during fast-paced sequences. The 180 Hz refresh rate is achievable via DisplayPort 1.4 (2560 × 1440 @ 180 Hz), while HDMI 2.0 supports up to 2560 × 1440 @ 144 Hz. Adaptive-Sync technology synchronises the display’s refresh rate to the GPU output, reducing screen tearing without introducing the input-lag penalty of V-Sync. AOC’s flicker-free DC backlight reduces eye fatigue during extended sessions, complementing six picture-mode presets (FPS, Racing, RTS, Gamer1, Gamer2, Gamer3) tailored to different game genres. The stand offers meaningful ergonomic flexibility: 120 mm height adjustment, ±30° swivel, and -5° to 23° tilt. The monitor is also VESA 100 × 100 mm compatible for wall or arm mounting. Connectivity is provided by one HDMI 2.0 port and one DisplayPort 1.2 port; there is no USB hub and no built-in speakers. The internal power supply accepts 100–240 V ~ 1.5 A, 50/60 Hz with a typical consumption of 26 W.
