RE: Dell WD15 dock NIGHTMARE! Anything can be done?
I am having the exact same problem. All my drivers and bios updates are installed in the correct order.
This dock was sold to me as a recommended accessory when I customized my Precision 7510 before purchase.
I will not run my UHDTV at full resolution even though the documentation says that it can.
I have had to resort to plugging everything in directly to my laptop & disconnecting my dock.
It is a total & utter waste of money.
