The ultimate portable design combines HDMI, Type C and charging port in one cable and completely replaces the Switch Dock and HDMI projection cable. High resolution and compatible: Hagibis Dock supports video resolution up to 4K (3840 x 2160P/30HZ) and is compatible with most HDTV, monitors, projectors and other devices with HDMI port. No additional driver is required. Note: Since Nintendo Switch itself only supports 1080P output, it can be up to 1080P 60Hz Charging when playing: with a smart chip certified by PD, it can effectively convert fluctuating voltage to stable voltage. This HDMI cable supports 100W PD fast charging, so you can play while charging and will not damage the switch console. Supported Device: Perfect support for Nintendo Switch, Mac Book Air/Mac Book Pro, Samsung S23 and other USB-C devices. Note: This USB-C adapter works with Nintendo Switch or Samsung DEX mode and requires an external power source. We recommend using the original switch charger or charger with output power more than 39W to avoid impairment of normal use.
