AOC CQ27G4 27 Inch Curved Gaming Monitor

The AOC CQ27G4 is a 27-inch curved gaming monitor built for players who demand sharp visuals and responsive performance in a single package. Centred on a Quad HD (2560 × 1440) VA panel with a 1500R curvature, it wraps your field of view to pull you deeper into every scene — from sprawling open-world landscapes to fast-paced competitive arenas. At the heart of the CQ27G4's performance is its 180Hz refresh rate over DisplayPort 1.4, ensuring animations and motion are rendered with exceptional fluidity. Pair that with a 0.5ms MPRT response time and Adaptive-Sync support, and screen tearing and motion blur become non-issues regardless of your frame rate. The VA panel technology contributes a native contrast ratio of 5000:1, delivering deep blacks that bring dark game environments to life in a way typical IPS panels cannot match. Colour reproduction is a genuine strength here. With coverage of 121% NTSC, 124% sRGB, and 101% DCI-P3, the CQ27G4 renders rich, saturated hues across a wide colour space. HDR10 support adds an extra dimension of brightness and contrast when content supports it, while colour accuracy sits at Delta E < 2 — a level meaningful for both gaming and casual photo-editing work. Brightness peaks at 300 cd/m² and viewing angles extend to 178°/178°, keeping the image consistent even when viewing off-axis. AOC's three-sided frameless design minimises distracting bezels, making the CQ27G4 well suited to multi-monitor arrangements. The stand offers generous ergonomic adjustment: 120mm of height travel, ±30° swivel, and -5° to +23° tilt, so you can dial in the perfect position during long sessions. A 100×100mm VESA mount option allows wall or arm mounting if you prefer. Connectivity covers an HDMI 2.0 port (capable of 2560 × 1440 @ 144Hz) and a DisplayPort 1.2 port (supporting up to 180Hz), with HDCP 2.2 on both. The internal power supply accepts 100–240V worldwide input and typical consumption is a modest 26W. AOC's flicker-free DC backlight and Low Blue Light mode round out the comfort-focused feature set for extended play sessions. — Verified Specifications — Screen Size: 27 inches | Panel: VA | Resolution: 2560 × 1440 (QHD) | Refresh Rate: 180Hz (DP 1.4) / 144Hz (HDMI 2.0) | Response Time: 0.5ms MPRT | Contrast Ratio: 5000:1 | Brightness: 300 cd/m² | HDR: HDR10 | Color Gamut: 121% NTSC / 124% sRGB / 101% DCI-P3 | Color Accuracy: Delta E < 2 | Viewing Angle: 178°/178° | Curvature: 1500R | Inputs: HDMI 2.0 ×1, DisplayPort 1.2 ×1 | VESA: 100×100mm | Stand Adjust: Height 120mm, Swivel ±30°, Tilt -5°~23° | Power: Internal, 100–240V, ~26W typical | Built-in Speakers: No | Warranty: 3 Years
