AOC AG275QSW Review: A 320Hz Gaming Monitor That Delivers Speed and Precision















AOC continues to elevate the competitive gaming scene with its latest addition—the AOC AG275QSW monitor, launched under the prestigious AGON Pro lineup. Sporting a sleek white chassis and loaded with high-performance specifications, this 27-inch monitor is purpose-built for esports enthusiasts and creative professionals alike. But does it live up to the hype? Let’s explore.

AOC AG275QSW Monitor Features

Immersive Visuals with Fast IPS and 2K Resolution

At the heart of the AOC AG275QSW lies a Fast IPS panel delivering a native 2560×1440 (2K) resolution, designed to balance image clarity with fluid gameplay. The monitor boasts an impressive 320Hz refresh rate via DisplayPort 1.4, ensuring buttery-smooth visuals for high-speed gaming. While the two HDMI 2.0 ports are capped at 144Hz, they remain sufficient for console gamers or dual-input setups.

Blazing Fast Response and Smooth Gameplay

Responsiveness is where the AG275QSW truly shines, with a 1ms GtG response time and a staggering 0.3ms MPRT, practically eliminating motion blur. Add to that Adaptive Sync and AOC’s proprietary MBRSync motion blur reduction, and you get crisp, tear-free visuals even in the most intense gaming sessions.

Color Accuracy and HDR Performance for Creators

Visual fidelity isn’t sacrificed either. With VESA DisplayHDR 400 certification, the display reaches a peak brightness of 450 nits in HDR mode and 350 nits in SDR. Color performance is equally impressive, covering 100% sRGB and 95% DCI-P3 gamuts. Each unit is factory-calibrated with a Delta E < 2, making it a capable tool not just for gamers but also for designers and video editors.

Smart Gaming Features and Customizable RGB Lighting

For gamers who demand extra functionality, the monitor includes smart gaming tools like a dynamic crosshair and sniper zoom, allowing users to fine-tune their aim in real time. Rear RGB lighting—customizable through AOC's Light FX system—adds aesthetic flair with 14 different effects, including sound-reactive options.

Ergonomic Design for Comfortable Use

Ergonomically, the AG275QSW is no slouch. The stand supports 130mm height adjustment, -5° to 23° tilt, 30° swivel, and full pivot rotation, ensuring comfort during long hours of use. For multi-monitor setups or wall mounting, it supports 100×100mm VESA compatibility.

Versatile Connectivity with KVM Support

On the connectivity front, users get a well-rounded selection: 2× HDMI 2.0, 1× DisplayPort 1.4, 2× USB 3.2 Gen 1 Type-A, 1× USB-B upstream, and a headphone jack. A notable bonus is KVM switch support, making it easier to control multiple devices with a single keyboard and mouse.

AOC AG275QSW Monitor Price

The AOC AG275QSW is currently available in China through JD.com at a price of 1999 yuan, which converts to approximately $278 USD. Given the combination of premium specs, advanced features, and factory calibration, this pricing makes it a compelling value proposition in the mid-range gaming monitor segment.
