Reasons to buy

280 Hz Refresh Rate

The AGON by AOC monitor, with its groundbreaking 280Hz refresh rate, is a game-changer for competitive gamers. Its lightning-fast speed and pinpoint precision give you an advantage in fast-paced games, allowing you to react quicker and hit targets with outstanding accuracy.

VESA Certified DisplayHDR™ True Black 400

The DisplayHDR™ True Black 400 delivers deeper, more accurate black levels, making your viewing experience richer and more immersive. No more washed-out dark scenes in movies and games — with True Black 400 you get a more realistic visual journey.

Wide Color Gamut

When enjoying photos, videos, or games, you want screen content to look as lifelike as possible. This display features Wide Colour Gamut technology, which enables it to show many more colours than conventional monitors through a hardware solution rather than simple software adjustments. The result: true-to-life images with fine details visible thanks to a broader colour palette.

Ergonomic Design

An ergonomic stand helps maintain comfort and 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.

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 for a free USB port.

Speakers

Built-in speakers make it simple to stay connected with family, friends, and colleagues. For movies, music, games, and more, you’ll enjoy quality audio without the need for external speakers.

E-sports Monitor Stand

Our new stand, co-designed with eSports professionals, lets you maximize free space for your peripherals. The base reduces the monitor's footprint on your desk and even allows you to place your keyboard on top. The stand includes cable management to keep your desk tidy. No matter what genre you compete in, we want you to feel like a pro.

Low Input Lag

Unleash your reflexes by switching to AOC Low Input Lag mode. This mode prioritizes raw response time over graphical frills, giving you the ultimate edge in hair-trigger confrontations.

1ms Response Time GTG — Grey-to-Grey

GtG (Grey-to-Grey) indicates how long it takes a pixel to change from one gray level to another. In gaming, every millisecond counts and can be the difference between hitting or missing a shot. A fast response time also reduces ghosting and motion blur.

VESA Certified DisplayHDR™ 400

VESA Certified DisplayHDR™ 400 is a notable step up from regular SDR displays. Unlike generic “HDR compatible” screens, true DisplayHDR™ 400 offers increased brightness, contrast, and color peak brightness of up to 400 nits; images come to life with vivid highlights and deeper, more nuanced blacks. It renders a fuller palette of rich colors for a more engaging visual experience.

Three-Year Warranty (OLED)

Warranty included: 3-year warranty (including coverage for OLED burn-in*). For more information, please refer to the Warranty Information page. OLED burn-in* coverage applies only when screen maintenance is performed according to the instructions provided here.
