A 31.5" 4K 240Hz OLED gaming monitor with 0.03ms response, 99% DCI-P3, HDR500 True Black and BlackShield film for 2.5X scratch resistance
Option 32" UHD 4K 240HZ
The ASUS ROG Swift PG32UCDM3 is a 31.5-inch 4K Tandem QD-OLED display built for competitive gaming and colour-critical work. Its 240 Hz refresh rate and 0.03 ms response time deliver motion clarity that matches fast-paced play. The panel covers 99% DCI-P3 with true 10-bit colour and Delta E<2 accuracy for professional editing.
Height, swivel and tilt adjustments let you set the screen to a comfortable viewing angle in seconds. The anti-glare coating reduces reflections without adding grain. ASUS OLED Care Pro with a Neo Proximity Sensor detects when you step away and blanks the panel to lower burn-in risk. BlackShield film adds 2.5X scratch resistance over earlier QD-OLED panels.
DisplayPort 2.1 UHBR20 provides the bandwidth for 4K at 240 Hz without compression. USB-C with 90 W Power Delivery charges a laptop while carrying video and data on one cable. HDR10 and VESA DisplayHDR 500 True Black compliance cap peak brightness at 1000 cd/m², so the brightest highlights stay clipped at that level.
