Ultra-smooth motion is provided by a 240Hz refresh rate and 1ms GtG response time, reducing blur and ghosting during fast action. The 1500R curvature increases immersion across the ultrawide 34" screen, while HDR400 enhances highlights and shadow detail. Ergonomic adjustments and a built-in USB hub improve comfort and connectivity, and G-Menu software allows convenient on-screen customization.

Reasons to buy

HDMI 2.1

The latest HDMI standard further increases supported refresh rates and resolution. This not only opens new possibilities for watching content, but also for gamers: HDMI 2.1 allows next-generation consoles to reach their maximum performance.

USB Hub

Built-in USB hubs in AOC monitors add convenience and practicality to your desk. Side-mounted ports are easy to reach without looking, saving time that would otherwise be spent searching the back of a PC case for a free USB port.

Ergonomic design

An ergonomic stand maintains comfort and helps prevent strain during long gaming sessions. It offers a wide range of motion with easy height, tilt, and swivel adjustments to support proper ergonomics and your personal preferences.

1500R Curved

The curved design wraps around you, placing you at the center of the action and providing a more immersive gaming experience.

G‑Menu

AOC G-Menu is a free PC tool you can install to get full customization paired with maximum convenience.

0.3ms MPRT Response Time

Enjoy a truly immersive gaming experience. Whether you're racing at high speed or in a high-stakes battle, every millisecond matters. The 0.3ms MPRT monitor offers fast reactions and smooth gameplay that can improve your performance.

240Hz Refresh Rate

240Hz fully unleashes top-end GPUs, delivering exceptional fluidity on screen. With details rendered sharply and motion shown clearly, your reactions feel more connected to the action and elevate your gameplay.

1ms Response time GtG — Grey-to-Grey

GtG (Grey-to-Grey) indicates how long it takes a pixel to change between gray levels. In gaming, every millisecond can make the difference between hitting or missing a shot. Fast response time also reduces ghosting and motion blur.

Fast VA

Experience visuals like never before with the AGON by AOC monitor. Deep blacks and high contrast ratios make images stand out, especially in darker scenes. Fast VA is not only about visuals but also precision: with quick response times, action stays fluid and clear even during intense gameplay. From fast-paced FPS titles to atmospheric RPGs, the AGON by AOC monitor enhances your gaming experience with swift performance and rich colors.

Wide QHD (WQHD) Resolution

With a 3440 x 1440 resolution, Wide Quad HD (WQHD) delivers superior picture quality and sharp imagery that reveal fine detail. The 21:9 widescreen aspect ratio is ideal for watching movies in a cinematic format or for immersive gaming, and it also provides additional workspace for productivity. True 8-bit color offers a wide palette for vibrant, natural-looking images.

Live the game at its best with HDR10

HDR10 further improves picture quality by enhancing the synchronization between your GPU or console and the monitor. This creates a more realistic, immersive, and smooth gaming experience—making each frame feel more lifelike.
