TOTU Docking Station for MacBook Pro Air XPS and Other USB-C Laptops

TOTU Premium 13-in-1 USB C Hub Pro Advanced All-In-One Connectivity provides a stable connection and increases the productivity of your device. 3.5Mm Mic/Audio slot 4K Display HDMI outputs crystal clear video streaming with incredible fluency. On mac devices, MAC OS through HDMI and VGA ports can only extend 2/3 monitors with "same screen contents" but different with the laptop display content. For windows system, 4k picture is shown only when a single HDMI is connected, otherwise, the pictures - - if your laptop is not in the list, please let us know, we are happy to help you check. We do not recommend adding an "extra extension cable or port conversion adapter" for the hub as it can cause slow transmission, HDMI port not being recognized, or other connective problems. Use HDMI cable 2.0a HDR 4k certified or above so that can get higher resolution. The USB ports are intended for data transfer. They only provide minimal 0.5A charging. ( Screen switch shortcut key: Windows+P). The "USB-C Female PD Charging" port is only for the power supply. It doesn't support data transfer.
