No, the 4-in-1 USB-C Slim Multiport Adapter 4K only supports direct HDMI connections, so HDMI to DisplayPort cables and other video converter cables are not supported.

Converter cables can lower video quality and cause connection issues. Connect an HDMI cable from the 4-in-1 USB-C Slim Multiport Adapter 4K directly to an HDMI port on your monitor. The HDMI port supports up to 4K at 60Hz.
