Windows 10 - Display remains black

[Thunder490]

Hi,

I have an Asus N76VZ laptop with Intel HD 4000 graphics and NVidia Geforce GT 650m (Optimus).

I use the laptop screen as well as a second monitor plugged in the HDMI output.

Just bought a Startech USB32HDPRO to add another monitor to use the laptop and 2 external monitors. Signal seems to go to the monitor (blue led lit instead of amber like when it is off) but the display is black.

Windows sees the monitor as active and display is extended to it.

Attached are the details from the support tool

Thanks
