Hi,
At the moment my money is on the video adapter cable you have being behind this issue. Although they all look the same they do differ significantly. The HP one I mention is one I know to work as it's one we test with. The Dell one you have is not one we test with.
If you can wait I will contact one of our overseas engineers to get a definitive answer on the video adapter cables as they work directly with the manufacturers.
Thanks,
James
