Product information

Description

Restart your gaming session with the AOC CQ27G4X, a 27-inch QHD curved monitor designed for immersive gameplay. The 2560x1440 resolution and 1500R curvature provide a wide, detailed field of view, while the VA panel and HDR10 support deliver high contrast and vivid colors. The monitor’s fast response characteristics and 180Hz refresh rate reduce motion blur for smoother action.

Advantages

The CQ27G4X combines a 27-inch QHD curved screen with a high 180Hz refresh rate and a 0.5 ms MPRT response time to minimize ghosting and provide fluid motion. HDR10 support enhances dynamic range, and the VA panel offers deep blacks and strong contrast. An adjustable eSports-style stand allows height customization for comfortable long sessions, and the G-Menu software enables on-screen tuning of settings.

Key specifications

  • Screen size: 27 inches
  • Resolution: 2560 x 1440 (QHD)
  • Panel type: VA
  • Curve: 1500R
  • Refresh rate: 180 Hz
  • Response time: 0.5 ms MPRT (up to 1 ms GtG)
  • HDR: HDR10 support
  • Stand: height-adjustable eSports base
  • Software: G-Menu for on-screen customization

How to use

Place the monitor on a stable desk and adjust the height of the eSports stand to align the screen with your eye level.

Enable the desired refresh rate and response-time settings in your graphics driver and use G-Menu to calibrate color, contrast, and on-screen display options. For HDR content, enable HDR support in both the monitor menu and the source device.

Recommendations

Reasons to buy

GMENU

AOC G-Menu is a free tool that you can install on your PC to have complete customization paired with maximum convenience.

E-sports monitor stand

Our new stand, co-designed with eSports professionals, lets you maximize free space for all your peripherals. The base of the monitor is designed to reduce the 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.

1500R Curved

The curved design wraps around you, putting you at the center of the action and providing an immersive gaming experience.

Height adjustable Stand

Raise or lower the screen to suit each individual's height and seating preferences. The easy-to-adjust stand ensures hours of comfort.

Low Input Lag

Unleash your reflexes by switching to the AOC Low Input Lag mode. Forget graphical frills: this mode configures the monitor to prioritize raw response time, giving the ultimate edge in hair-trigger stand-offs.

180Hz Refresh Rate

Competitive and intense gaming demands top technology to ensure lag-free, smoother play. This AGON by AOC monitor features a 180Hz refresh rate, making it 3× faster than a standard display. Lower frame rates can make enemies appear to jump from spot to spot on the screen, making them difficult targets to hit. A 180Hz frame rate restores those critical missing images, showing enemy movements in ultra-smooth motion and making them easier to target. With this AGON by AOC gaming monitor, you won't have to tolerate input lag and screen tearing.

0.5ms MPRT - Moving Picture Response Time

MPRT stands for Moving Picture Response Time. MPRT technology momentarily disables and enables your monitor backlight during picture changes. By reducing the time a frame is shown on the monitor, ghosting and blurring effects are reduced, resulting in a smoother, more fluid-feeling gaming experience.

1ms Response time GTG - Grey-to-Grey

GTG stands for Grey-to-Grey and indicates how long it takes for one pixel to change from one gray level to the next. In gaming, every millisecond counts and can be the difference between hitting or missing a shot. Fast response time also eliminates ghosting and motion blur.

QHD Resolution

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 ample space to spread out and work, and lets you enjoy games or movies in their original size.

Live the game at its best with HDR10

HDR10 further enhances picture quality by improving synchronization between your GPU or console and the monitor. This creates a more realistic, immersive, and smooth gaming experience — you’ll feel immersed in the game, frame by frame.
