Unfortunately, the JCD324B is a plug and play device and therefore will only support one external monitor plugged in at a time. With the USB-C port on the JCD324B, that is actually for data transfer only, it cannot be used for an additional monitor since it is not a Thunderbolt 3 port. However, if you wish to use multiple monitors I would recommend the JCD381 as it requires a driver to be downloaded and installed and that will allow the use of two HDMI monitors, Ethernet and two USB-A ports for mice, keyboards, flash drives, cameras. ** Feel free to contact us with our information on the packaging for Technical Support, device warranty registration or if you have any other questions and/or require any further
assistance and someone will be glad to assist you. Be sure to check out our website for other devices that could also be of great usage to you and your colleagues.
Just as a heads up, we also provide both Spanish and English speaking Technical Support. Thanks.
