Thank you for posting!
I can see that you have also reached out to us directly via firstname.lastname@example.org with the same question. I have merged your two separate requests together to help keep all communication in one place and prevent duplication of effort, and I have just sent my direct reply.
For the benefit of anyone else following this thread, the salient points of my direct response are included below:
"Our USB docking stations are based on DisplayLink technology, which is in essence a ‘virtual’ graphics adapter that relies on the host system’s CPU and internal physical graphics adapter resources to generate the image shown on the attached displays. DisplayLink-based products do not have graphics adapters (video cards) within them.
Based on your description and requirements, I believe our USB 3.0 Dual Display Adapter known as the USB3-3900DHE will meet your needs --> https://plugable.com/products/usb3-3900dhe/
The USB3-3900DHE adapter will connect to one of the USB 3.0 ports within your HP docking station (or directly to the laptop) and provide the ability to add up to two 1920x1080 resolution displays to your system. The adapter has one HDMI video output, and one DVI video output. We also include in the box a DVI to VGA adapter if needed.
Should you elect to proceed with a purchase and find that the adapter does not meet your needs, we do offer a 30-day no-hassle return policy for all products sold by Plugable and fulfilled by Amazon. "
