"Forcing" output?

Hello!

I recently bought a USB 3.0 display adapter. Device manager tells me it´s called "DisplayLink Display adapter (4300)".

Anyway, what I´m trying to do is connecting my device to a control card for a LED wall / LED screen through DVI. The problem is my adapter won´t recognize it as a monitor.

Is there any way of "forcing" the adapter to output signal to my control card?

Thanks in advance,
/Stefan

The adapter will only enable the output if it sees DVI hotplug asserted. I suspect there is no hotplug event, which stops the output being enabled.
