How come my monitor has no image when connecting to a Mac through USB-C?


Please make sure to connect your Mac and monitor with a BenQ USB-C cable or a USB-C cable which is certified by the USB-IF and features power delivery as well as full video, audio, and data transmission. Some USB-C cables for Mac are USB-C charge cables and do not support video. Also, please make sure the correct resolution and refresh rate are selected on your Mac and the monitor.
