Bolstered for battle, the 24.5" TN Panel AG251FZ AMD Free-Sync monitor brings you seamless, lag-free gaming with the pro gaming-standard 240Hz refresh rate. Includes convenience-focused signature AGON features to optimize gameplay.


AMD FreeSync 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 200 levels of detail for a better game experience.

Ultra-fast 240Hz refresh rate and 1ms response time enable the sharpest responses.

AOC Shadow Control enables fast contrast adjustment of overly dark or bright areas through the OSD menu, while retaining quality on more balanced areas on-screen.

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.

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.

AOC gaming monitors are very easy to connect. The AG251FZ 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.
