RE: Latitude E7470 External Monitors with Dock Problems
jfrink, and anyone else reading this thread,
It seems like this is an obvious problem that is extraordinarily poorly supported by Dell, and will apparently continue to be so since no response has been made to this thread in well over a week by any Dell employee.
That being said, you may as well just take the option that I went ahead with -- switch over to a USB 3.0 docking station. It uses an entirely different display driver and I'm able to be up and running with 3 monitors (2 external and 1 from the laptop) with no blinking, flashing bulls**t to worry about.
I went with this linked docking station, but there are a ton of others for similar price that do the same thing. At the end of the day, a result is a result, and I was sick of waiting to get an answer on this issue.
