Bolstered for battle, the 27" TN Panel AG271QX Adaptive Sync monitor brings you seamless, lag-free gaming with the pro gaming-standard 144Hz refresh rate. Take control of the battlefield in crystal-clear Quad HD (2560 x 1440) resolution. Includes convenience-focused signature AGON features to optimize gameplay.

With 2560 x 1440 resolution, Quad HD (QHD) offers superior picture quality and sharp imagery that reveals the finest details. The widescreen 16:9 aspect ratio provides plenty of space to spread out and work, plus allows you to enjoy games or movies in their original size.

Adaptive Sync technology synchronizes the GPU and the monitor so frames are displayed when ready - no tearing or stuttering.

  • High performance solution with all the benefits of variable refresh rate technology.
  • Based on industry standards, not expensive proprietary solutions.
  • Cheaper and easier to implement: no additional monitor hardware, no license fees.
  • Cheaper for consumers.
  • Support multiple use cases: Gaming, Video, Power Saving.

With AOC Game Color, adjust colour saturation and grey level with 20 levels of detail for a better game experience.

Conventional 60Hz monitors can show distracting motion blur when displaying games with rapid movement.

Ultra-fast 144Hz refresh rate and 1ms screen response time combine to enable sharper action.

With Shadow Control gamers can dial-in shadow levels in the OSD Menu to increase contrast for better dark areas on the screen definition without affecting the rest of the screen.

Low Input Lag reduces delay between signal input (via keyboard, mouse or otherwise) and image processing on the screen to ensure a smoother gaming experience.

Low Blue Mode software, featured in all AGON displays, reduces harmful blue light emission (wavelengths under 455nm) found in most monitors. This ensures your eyes stay protected, especially over longer gaming sessions.

Most monitors use Pulse Width Modulation (PWM) to control brightness. The pulsing creates flicker which can cause eye strain and other discomforts. Flicker Free constantly powers the backlight with Direct Current (DC) instead. Play safely.

AOC gaming monitors are very easy to connect. The AG271QX has several external input ports, but also has dedicated USB 3.0 and device-charging ports, making it easy for you to charge your mobile device or transfer data while focused on your gaming session.

The fully adjustable stand allows convenient adjustment of the screen’s height and angle. Match the screen’s position to your chair position, height, and line of sight for a comfortable playing experience.
