Intel HD 530 doesnt detect 3rd monitor

[MKlem]

Hello.

I want to use 3 monitors, the one from laptop, one through HDMI and one through USB -> VGA convertor, but I'm not able to make it work together.

Default display and HDMI works fine, but I have trouble connecting the third one. Actually, if I disconnect the HDMI, I still am not able to connect the USB->VGA monitor.

The installation of convertor driver was successfull, the monitor stopped showing "NO INPUT SIGNAL" message and notification LED turned from orange to green. What is strange is that in Windows (10) display settings I can see 3 monitors, in nVidia management panel I can see 3 monitors, but Intel Graphics Control Panel shows only 2 monitors.

PC: Dell Inspirion Gaming 7566

OS: Windows 10

All drivers are kept actual. The USB->VGA converter is from company named Secomp International branded as "Value"

Oh I forgot to mention that I get only black screen on the USB->VGA display...

Are three-display configurations supported using a USB display?

No, using a USB display does not support three-display configurations.
