Plugable USB 2.0 UGA doesn't work well with Dell Venue 8 Pro Win10... please

I have a Venue 8 Pro with Win10. I tried to connect it to a hdmi monitor using a Plugable USB 2.0 UGA, but it doesn’t work. When I plug the adapter to the tablet, it’s recognized correctly, but the monitor says that there’s no hdmi signal: why?? there’s a problem of compatibility or what?
I installed the driver correctly!!

problem solved!
it was due to the hdmi cable.

question: the Plugable support is excellent, but why anyone in this community answear to my question?

Just to confirm what Oscar mentioned:

This problem was due to an EDID (…) problem. USB display adapters will not display without recognizing this EDID signal. This problem can be fixed by swapping out your existing video cable with a new (or different one) one.
