Currently, mainstream display devices, projection devices and video acquisition devices generally provide hardware that supports 1080P60HZ resolution, and the USBTYPE-C interface is also the mainstream of current handheld devices. More and more brand products only have USBTYPEC output interface, and the display screen of handheld devices is small, and the clarity of video playback is limited. In order to connect handheld devices such as notebooks, mobile phones, tablets and other devices with USBTYPEC interface to playback devices and ultra-high-definition signal display devices such as projectors and other display devices, signal conversion cables with USBTYPEC to VGA interface have appeared;
