This 31.6-inch 4K QD-OLED monitor targets creators and everyday users with a 120Hz refresh rate, Dolby Vision, DisplayHDR True Black 400 and AI-enhanced spatial audio from built-in speakers. Its most notable trait is that it drops a dedicated DisplayPort connector: video arrives over one HDMI 2.1 port and a USB-C upstream that supports DisplayPort 1.4 Alt Mode with up to 90W of power delivery, so a laptop can display and charge over a single cable. Two additional USB-C downstream ports provide 5Gbps data and 15W charging for peripherals.
