Are my USB ports 3.0

I have an HP Zbook 14. USB Ports are supposed to be 3.0.

I have connected a USB to VGA adaptor but it says the USB port is not 3.0 (Reports 2.0). (Windows 8.1)

The bottom line is the VGA screen can only handle limited resolution.

Any ideas?

They should be all USB 3.0 for ZBook 14.

A visual inspection of your USB port will tell you quickly. A USB 3.0 port will have one or both of the following indicators:

1. The port will be blue instead of black.
2. The port will have a small "ss" logo next to the USB icon.

If one or both of these conditions are met then you have a USB 3.0 port.

I guess the problem is in the USB 2 VGA adaptor

That could very well be. A USB 3.0 port will happily work with USB 2.0 devices. I suspect the adapter is a USB 2.0 device.
