This 49-inch DQHD (5120×1440) curved QD-OLED runs at 240Hz, and Samsung made an unusual port choice: its second HDMI 2.1 input is a Micro HDMI (Type D) connector rather than full-size, so you may need a Micro-HDMI-to-HDMI cable or adapter for a second source. The DisplayPort 1.4 input uses DSC to drive the full 5120×1440 at 240Hz. Watch out for the USB-C-shaped ports — both the upstream and the two downstream connectors are data-only and do NOT carry DisplayPort Alt Mode or USB Power Delivery. The monitor runs from an external power adapter.
Samsung’s 49-inch DQHD 240Hz QD-OLED with DisplayPort 1.4, HDMI 2.1, a Micro HDMI 2.1 input, and a data-only USB-C hub.
