I've got an Dell XPS 15 9560, and I've bought a USB-C to DVI adapter: https://www.amazon.co.uk/ICZI-USB-C-Thunderbolt-Compatible-Adapter/dp/B01MU2WQWD/ref=sr_1_1?s=electronics&ie=UTF8&qid=1492521757&sr=1-1&keywords=usb-c+to+dvi
Windows recognises the monitor, shows it up in display settings but I get no picture. I can drag windows off the edge of my 2nd screen (via HDMI-DVI) onto the 3rd screen (USB-C to DVI) but the screen stays black.
I've got latest Nvidia drivers (the ones that it shipped with were out of date) I've tried both a Benq and LG monitor, neither work on the USB port but both work on the HDMI port, so they are fine.
I've got a replacement adapter sent out and it still doesn't work.
Is USB-C to DVI-D just not possible?
Should I try USB-C to VGA or HDMI
Why would windows detect the monitor in settings but not render it?
Am I just dealing with dodgy display adapters?
Should I be saying USB-C or Thunderbolt?
Here's an image from the Nvidia control panel, showing the hardware is properly detected
Got a response from the vendor that sold me the laptop, this was what they said:
The thunderbolt connection is not compatible with a DVi connection. You will require a USB-C to display port adapter and a display port male to display port male cable.
So according to them thunderbolt/usb-c is not compatible with DVI.
