Latitude e6430, E-Port dock + 2 U2415 = duplicate display

Question

I have a Latitude e6430 and a Dell E-Port 3.0 dock (not the Plus), and 2 U2415 monitors. When I connect to the DP on the dock and daisy chain the monitors, I get both monitors active but they are duplicate displays. I've enabled DP 1.2 on both monitors and cables are DP 1.2 capable. I want to have the monitors be separate displays, but I cannot find any option to do so in Windows, Intel or Dell display managers. Is this even possible in this configuration? If not, what configuration would I require to have the U2415s as separate displays?

Thanks,

Steve

What is the manufacturer 5 digit part number on that dock? The four docks that have DP 1.2 are T0J21, 8W9HM, XX6F0, GNPHP. The second monitor in the daisy chain should have DP 1.2 disabled.

Hi Chris,

If you mean the DP/N, it is WV7MW A02. If that's not it, then how do I ID the part number? if I have the wrong one, can you help me ID what I should purchase?

I ordered this using Dell part number 331-6307, which claims DisplayPort 1.2 capability, and on the site it says the part number should be XX6F0 (but I apparently didn't get that one).

I do have DP 1.2 disabled on the second monitor.

Thanks,

Steve

I'm thinking this is not necessarily a dock problem, as someone else was able to dock their machine and see the two monitors as separate (extended) displays. I have Intel HD4000 graphics only--could this be my showstopper? If not, could the E-Port Plus dock (with two separate DP outputs) be usable instead?

Thanks,

Steve

I do not see WV7MW on the Dell parts page? The four I listed are $219.99 and $169.99.

I do not know about the limitation of the Laptop GPU. You would need to ask the Laptop users here.
