No Signal: USB 2.0 Diplay adapter
 

I have a computer with 4 screens:

• Screen 1: graphics card
• Screen 2: graphics card
• Screen 3: USB 2.0 display adapter (
• Screen 4: USB 2.0 display adapter (

This setup is great and has been working fine for over 2 years.
I now need a 5th screen, so I bought a new USB 2.0 display adapter.

SETUP: Monitor > HDMI to HDMI cable > HDMI to VGA adapter > USB 2.0 display adapter > USB PC

But… when I turn the monitor on, there is a sign it flicks between settings (DVI, VGA.. etc)… but then it just says:
“No Signal”….

If I right click on windows and do display settings > it shows 5 screens here connected…. But the screen has no signal.

Please assist me
