Extra monitor via DL

[AlbanRampon]

Hello Denis,

First, to avoid you buying un-necessary hardware, UHD is 4K and QHD is 2560x1440.
We don't have any USB2.0 only chip at that resolution, as the DL-165 goes to 1080p only.
You can use a USB3.0 adapter doing 2560x1440 on USB2.0, with impact on performance.

You can use it to add a display.
Your Intel graphics card drivers for both your machines are far too old to support duplicated screens across graphics adapters. This is a function introduced as compulsory in Windows 10, and Intel only retrofitted the feature back to Intel 5th generation. Cloning/duplicate anyway requires identical resolutions, which is not what you want.
But you can extend: two external displays with different content, one driver by the hard dock, and one driven by the USB adapter/dock.

Generally, neither machine was conceived to run properly on Windows 10 so your experience is unlikely to be optimal.

Kind regards,
Alban
