First, tell us the brand and model of laptop as well as the video hardware
used. I've seen quite a few laptops where the external port did not have
the same specs as the internal port.
If your laptop has the ability, normally a Fn key, to drive only the
external port, then I would first play with only driving that port.
One meets his destiny often on the road he takes to avoid it.
