LG's unusual 16:18 stacked-aspect monitor delivers a 27.6-inch 2560×2880 SDQHD Nano IPS panel — effectively two 16:9 screens stacked. The two HDMI inputs are HDMI 2.0 (not 2.1), which is fine because the panel runs at 60Hz; full 2560×2880 at 60Hz is comfortably within HDMI 2.0 bandwidth. DisplayPort 1.4 and USB-C with 90W PD give you full-bandwidth options, and the USB-C path lets a single cable carry video, data and laptop charging.
