Thanks for the info Huy Le & Hannes.
We're still actively working on this issue, but I have no updates on it yet.
@Huy Le: What OS do you have installed? Is it 32 or 64 bit? What driver do you have installed? Are you using an AV/R?
@Hannes: What external display are you attempting to connect to? Are you using an AV/R?
Thanks,
