Immersive 27-Inch QHD Curved Display
Experience detailed gaming visuals on the 27-inch QHD display with a resolution of 2560 × 1440. QHD provides greater image detail than Full HD, allowing game environments, textures and objects to appear sharper and more defined.
The 1500R curvature wraps the display around your field of view, creating a more immersive gaming experience while keeping the action comfortably within your visual range.
The 16:9 aspect ratio provides compatibility with a wide variety of games, applications and multimedia content.
Fast VA Panel with 5000:1 Contrast
The CQ27G4 uses a Fast VA panel designed to combine responsive gaming performance with excellent contrast.
With a 5000:1 native contrast ratio, the panel can produce deeper blacks and brighter whites, helping dark game environments retain greater depth while maintaining detailed highlights.
The VA technology also provides a 178° viewing angle, making the monitor suitable for both focused gaming and shared viewing.
Smooth 180Hz Refresh Rate
The 180Hz refresh rate allows the monitor to display significantly more frames per second than conventional 60Hz displays.
This results in smoother camera movements, faster transitions and improved visual fluidity during demanding gameplay.
The high refresh rate is particularly beneficial for:
- First-person shooters
- Racing games
- Battle royale titles
- Competitive esports
- Action games
- Fast-paced multiplayer games
0.5ms MPRT Response Time
With a 0.5ms MPRT response time, the AOC CQ27G4 is designed to keep fast-moving objects clearer and reduce perceived motion blur.
Combined with its 180Hz refresh rate, the monitor provides the speed and responsiveness required for competitive gaming, where quick reactions and clear target tracking can make a difference.
HDR10 and 300 Nits Brightness
The CQ27G4 supports HDR10, helping compatible games and multimedia content deliver a wider range of brightness and contrast.
Its 300 nits brightness provides clear visibility in everyday gaming environments, while HDR support adds additional visual depth to compatible content.
