FreeSync Premium Pro drives brilliant, fast tear-free performance

Screen tearing and stuttering doesn't only harm gaming performance, it also destroys immersion. AMD FreeSync Premium Pro keeps your monitor's refresh rate synced with your processor's. It also supports 120Hz and higher refresh rates; Full HD or above resolution; low latency (in both SDR and HDR); and works with HDR in line with strict color and luminance standards to deliver the ultimate gaming experience.

144Hz Frame Rate and 1ms

With a 144Hz refresh rate and 1ms response time, your display will be equipped to perform at the pro gaming standard. Enjoy an ultra-smooth experience with no visible screen blur to ensure you're always prepped to win.

DisplayHDR 400

AOC display meets the trusted and official VESA DisplayHDR 400 standard, which means better contrast and color accuracy. Brighter lights, darker shadows, and more vivid colors everywhere bring inspiring levels of clarity and immersion.


At 2560 x 1440 resolution, Quad HD (QHD) offers superior picture quality, sharper images and finer details, without changing the screen shape, so Full HD videos will still fill the whole screen.


Curved screens offer a more immersive user experience that puts you at the center of the action. By mimicking the curvature of the eye, it is also less straining to track movement around the screen. The screen’s deeper-than-average curvature provides a more engaging experience and allow you to enjoy beautiful visuals from almost any angle.

Light FX

AOC Light FX offers a brand-new immersive gaming experience by emitting ambient light during gameplay. Choose 13 default modes or customise the technology to flash team colors at e-sport events. AMD FreeSync models even have a bonus function of pulsing colors along to music.


With DTS audio tuning technology, you can enjoy a theatre-like audio experience from your screen without needing to buy extra speakers or headphones.

Game Mode

It can be a hassle to adjust monitor settings every time you load up a new game. AOC Game Mode allows quick adjustment and pre-designed setups (tailored for different genres) to enhance the gaming experience.

Shadow Control

AOC Shadow Control enables fast contrast adjustment of the in-game image. It improves areas of the screen that are too dark or washed out without affecting the rest of the screen.

Low Blue Mode

Long exposure to short wavelength blue light may cause eye strain, sleep disorders, or headaches. AOC Low Blue Mode puts the user first by reducing the screen’s short wavelength blue light emission without sacrificing color accuracy. Also provides four different filtering modes – reading, web browsing, multimedia, and office.

HDMI & DisplayPort

HDMI compatibility unlocks a wider array of connectivity options for users, including gaming consoles, laptops, Blu-Ray players, and more.
DisplayPort is the main PC-to-monitor connection format in the industry, with better refresh rates and the ability to carry audio in addition to visual data.
