I use a Lenovo 410 laptop for navigation (Open CPN which I highly recommend!) located at the nav station and want to add a repeater screen above the helm.  I have a HP monitor that is powered through and takes the video feed via USB C.  The laptop only has USB 2 ports (which work nicely for GPS and AIS inputs).  VGA to USB C cables do not power the monitor; a USB 2 to USB C cable powers but does not support the video feed.  

Has anyone found a port converter or express card that I can use?

Thanks,
