The AOC Q27G4/WS QHD Gaming Monitor is a 27-inch Fast IPS display built for competitive play and sharp everyday visuals. With 2560 × 1440 (QHD) resolution, a 200Hz refresh rate, and 0.3ms MPRT motion response, it delivers crisp detail and ultra-smooth gameplay. Moreover, Adaptive Sync helps keep action fluid, while VESA DisplayHDR 400 adds extra pop in supported content for more dynamic highlights and contrast.

QHD Clarity for Sharper Detail

Quad HD resolution gives you noticeably more detail than Full HD, making textures, UI elements, and small text look cleaner. As a result, it’s great not only for gaming, but also for editing, browsing, and multitasking where extra clarity matters.

200Hz Smoothness for Competitive Gaming

Speed is the main highlight here. With up to 200Hz, motion looks far smoother, which helps tracking targets and reacting faster in fast-paced titles. In addition, 0.3ms MPRT reduces perceived blur in quick scenes, so movement feels sharper and more controlled.

Tear-Free Motion with Adaptive Sync

To avoid the “broken frame” look, Adaptive Sync synchronizes the display with compatible GPUs to reduce tearing and stutter. Therefore, gameplay feels more consistent, especially when frame rates fluctuate.

HDR400 Impact + Low Input Lag Focus

The monitor includes DisplayHDR 400 support to enhance brightness and contrast in HDR-ready games and videos. Meanwhile, features like Low Input Lag mode and built-in gaming presets help you tune the screen for different genres without overcomplicating settings.

Comfort and Practical Setup

For longer sessions, Flicker-Free technology helps reduce screen flicker, improving comfort over time. Plus, it supports HDMI and DisplayPort for easy connection, and VESA mount compatibility makes it simple to place on an arm.
