DOMINATE AT 360 HZ
ROG OLED technology gives you the upper hand over the competition ― thanks to crisp 1440p visuals and supersmooth gameplay at an astounding 360 Hz.

OLED ANTI-FLICKER
ROG-exclusive OLED Anti-Flicker technology offers three refresh rate ranges ― High, Mid, Off ― to reduce flicker during frame rate fluctuations and maintain an immersive gaming experience.

NEXT-GEN QD-OLED TECHNOLOGY
Graphene film
A graphene film behind the QD-OLED panel helps reduce operating temperature. Graphene is the thinnest and strongest nanomaterial in the world, and has high thermal conductivity to help effectively dissipate heat.

Advantages of OLED technology
The extremely high contrast ratio offered by OLED technology ensures the deepest black hues and vivid colors. Plus, an astounding 0.03 ms gray-to-gray (GTG) response time ensures supersmooth, low-latency gameplay. These features not only make the XG27ACDNG perfect for gaming, but also for professional video- and photo-editing.

ADVANCED CUSTOM HEATSINK
The custom passive heatsink found in the XG27ACDNG prioritizes heat dissipation. In addition, the monitor’s back cover features top vents that further improve cooling to significantly reduce the risk of burn-in.

ASUS OLED Care+
New ASUS OLED Care+ software provides a full set of customizable monitor settings to protect the OLED panel and ensure longevity of the screen. All the settings can be easily managed through the DisplayWidget Center.

SMOOTH AND RESPONSIVE
The XG27ACDNG features NVIDIA G-SYNC compatible and AMD FreeSync Premium Pro technology, ensuring super-smooth, tear-free visuals with low latency.

ASPECT RATIO
For gamers who typically use smaller monitors, the XG27ACDNG is able to display a 24.5-inch image, a 4:3 aspect ratio image, or a full-screen 4:3 aspect with deep black OLED borders around the image. For FPS players, playing on a full-screen 4:3 aspect ratio makes in-game targets or character models look slightly larger, making them easier to hit.

EXTENSIVE CONNECTIVITY
A multitude of connectivity options ― including one DisplayPort 1.4, two HDMI 2.1 ports, USB-C with 90 W Power Delivery and a USB hub ― provide support for a wide array of multimedia devices.
