Most modern laptops that support USB-C DisplayPort 1.2 Alt Mode should support two displays. You may need to research your laptop's technical specifications to determine exactly which version of DisplayPort it supports. If you are unsure or cannot find the appropriate technical specifications, you may want to contact the computer manufacturer's support team for more detailed information.
