Hi, I'm Elise, and I'd be happy to help with your issue.
Unfortunately not every device supports display over USB, is suspect this may be the case with your HP device. Or that the USB port is not supplying enough power to the display.
Either way, you would need to check with HP support to see if your device is compatible with the display or not.
Please let me know if you need any further assistance.
Kind Regards,
Elise
