ASUS ROG Swift OLED PG27UCDM

The small pixel pitch (about 166 ppi) makes text and interface edges look sharper than on 27-inch 1440p monitors.

All inputs support 240 Hz at 4K; variable refresh prevents tearing and stutter as the game frame rate moves between 48 and 240.

Grey-to-grey transition time; because OLED pixels change much faster than LCD, motion blur depends mostly on the refresh rate.

1,000 cd/m² is a peak reached on a small area of the screen; a full white screen stays much lower. ASUS gives no typical SDR brightness value.

The True Black tier measures OLED’s very low black level; 400 is the minimum peak brightness threshold in the certification test. Dolby Vision support lets compatible sources use scene-by-scene HDR data.

ΔE < 2 means factory calibration deviates from target colours by an amount most people cannot see; a calibration report is included.

USB-C takes video over a single cable and supplies up to 90 W to a laptop. The HDMI 2.1 inputs can be used for 4K 120 Hz on consoles.

KVM moves the keyboard and mouse attached to the monitor between two computers when the input is switched.

A headphone jack or external speakers are needed for audio.

OLED Care includes burn-in prevention functions such as pixel cleaning, screen shift, logo brightness adjustment and taskbar detection. The proximity sensor dims the screen when the user leaves, reducing static image time.

The tripod socket is used to mount accessories such as a camera or light on the stand.

Warranty terms can vary by country.
