QD stands for Quantum Dot and Silent Display
ASUS ROG Swift OLED PG32UCDM is a flat QD-OLED monitor with a size of 31.5 inches, a resolution of 3,840 x 2,160, and supports DisplayHDR True Black 400. It can reach a 240Hz refresh rate and offers a wide range of connections, including two HDMI 2.1 and a single DisplayPort 1.4. Three USB 3.2 Gen 2 Type-A, and the last USB 3.2 Gen Type-C, with power delivery up to 90W. There are two other things that the PG32UCDM does not have. The ASUS monitor does not have speakers and no fans. They are all passive cooling.
3D gurus love almost everything about this monitor, except for the glossy coating on the monitor, which might put some readers off. The color gamut is impressive and the brightness uniformity is very good, which is obviously more important than the coating. Check out the full review.
