USB Monitors will not work with hp 840 G3 Laptop

[AlbanRampon]

Hello,
When you say the system does not recognise the display, do you see the monitor in Device Manager?
If you don't, it's unlikely to be a driver issue as Windows needs to know the device is present before associating drivers.
If you don't see it, are you using a Y-cable to get power from 2 USB ports?
You can see in my forum signature how to submit your details by email to create a support ticket with your logs.
Kind regards,
Alban
