ASUS ROG Swift OLED PG27UCDM

The ROG Swift OLED PG27UCDM is ASUS’s 26.5-inch 4K (3840 × 2160) 240 Hz QD-OLED gaming monitor: 0.03 ms response time, DisplayHDR 400 True Black, Dolby Vision, DisplayPort 2.1, two HDMI 2.1 ports and USB-C with 90 W power delivery. The high pixel density makes small text sharp; against burn-in there is ASUS OLED Care and a 3-year warranty that also covers burn-in. Owners praise the colour and contrast and mention purplish blacks in a sunny room and shipping with old firmware. In one firmware version DSC could not be turned off; this was fixed in the next version.
