27-inch 4K OLED gaming monitor

The ASUS PG27UCDM is a 27-inch gaming monitor with a 4K UHD OLED panel running at 240 Hz. It covers 99 % DCI-P3 and 145 % sRGB with Delta E under 2 for colour-accurate work. The 0.03 ms response time and 1,500,000:1 contrast ratio serve competitive players and content creators alike.

Sustained-load behaviour

A custom heatsink and the ROG OLED Care Pro suite with Neo Proximity Sensor manage heat and burn-in risk during long sessions. The sensor blanks the screen when no user is detected, while OLED Anti-Flicker 2.0 reduces flicker by 20 % compared with earlier panels. Uniform Brightness and Adjustable HDR keep luminance stable across varying average picture levels.

Connectivity and ergonomics

DisplayPort 2.1a UHBR20 delivers 80 Gbps for uncompressed 4K at 240 Hz, joined by two HDMI 2.1 ports and a USB-C input with 90 W power delivery. Three USB 3.2 Gen 1 Type-A ports handle peripherals. The stand provides 120 mm height travel, +20° to -5° tilt, ±30° swivel and full ±90° pivot for flexible desk setups.

Questions about this item

Will my graphics card drive 4K at 240 Hz without compression?

Yes, the DisplayPort 2.1a UHBR20 port supplies 80 Gbps bandwidth, enabling uncompressed 4K at 240 Hz from a compatible GPU.

Can I charge a laptop through the monitor while gaming?

The USB-C port delivers up to 90 W power delivery, so most ultrabooks and thin-and-light laptops can charge while displaying 4K video.

How does the monitor protect the OLED panel from burn-in during long sessions?

The Neo Proximity Sensor blanks the screen when you step away, and the custom heatsink plus OLED Care Pro routines reduce static-image stress.
