Ultra Fast 360Hz Gaming

The 360Hz refresh rate allows the monitor to update the image up to 360 times every second. When paired with a gaming PC capable of producing high frame rates, this provides exceptionally smooth movement and improved visual tracking during fast paced gameplay.

The extremely fast 0.03ms Grey to Grey response time helps reduce ghosting and motion blur, allowing moving objects to remain clear during competitive shooters, racing games, esports titles and other reaction focused games.

QHD QD OLED Display

The 2560 x 1440 QHD resolution provides significantly more image detail and desktop space than a standard Full HD display while remaining suitable for high refresh rate gaming.

QD OLED display technology combines self illuminating OLED pixels with Quantum Dot colour reproduction. Each pixel can switch itself off independently, producing true blacks, excellent contrast and precise control over bright and dark areas of the image.

Exceptional Colour and Contrast

The display supports true 10 bit colour with approximately 1.07 billion colours. It covers 99 percent of the DCI P3 colour space and 135 percent of the sRGB colour space, providing vibrant and accurate colour reproduction.

Factory calibrated colour accuracy with a Delta E of less than 2 makes the monitor suitable for gaming, streaming, photography, video work and other colour sensitive applications.

A typical contrast ratio of 1,500,000:1 allows dark scenes to appear deep and detailed while bright highlights remain vivid and impactful.

HDR Performance

The XG27ACDNG supports HDR10 and is certified to the VESA DisplayHDR 400 True Black standard. HDR peak brightness can reach up to 1,000 cd/m² in supported content and display conditions.

OLED technology provides precise lighting control at individual pixel level, helping reveal detail in both dark shadows and bright highlights without the halo effects commonly associated with conventional backlit displays.

FreeSync Premium Pro and G SYNC Compatible

AMD FreeSync Premium Pro and NVIDIA G SYNC Compatible support allow the monitor to synchronise its refresh rate with a compatible graphics card.

Variable refresh rate technology can reduce visible screen tearing and stuttering when frame rates fluctuate, providing a smoother and more consistent gaming experience.

ROG OLED Anti Flicker Technology

OLED displays can sometimes show visible flickering when frame rates change significantly. ROG OLED Anti Flicker technology helps reduce this effect during variable refresh rate gaming, improving comfort and image stability.

ASUS OLED Care Plus

ASUS OLED Care and OLED Care Plus provide a collection of features designed to help protect the panel and reduce the risk of permanent image retention.

The monitor also uses a custom heatsink and an advanced internal airflow design to manage panel temperature efficiently and support long term OLED reliability.

OLED protection settings can be accessed through the monitor controls or through ASUS DisplayWidget Center software.

Warranty and Product Information

Please note: Achieving the maximum 360Hz refresh rate requires compatible graphics hardware, a suitable connection and the correct display settings. USB C charging performance depends on the connected device and cable. OLED displays can experience image retention when static content is shown for extended periods, so the supplied OLED Care features should remain enabled and the manufacturer usage guidance should be followed.
