I have an AOC E1670SW USB monitor that I want to connect to my Windows 10 installed laptop.

When connected, the monitor powers up but shows "No Signal" message. The laptop is unable to detect any external monitor. I have tried the Fn + F4 and Shift + F4 key combination but that also does not work.

I have also tried installing DisplyLink software and the drivers(only .icm and .inf files available).

The USB connection is for power only. You still need to connect a VGA cable for the video signal.

  • Oops! I just realised that. My bad.
