Question 1

Has anyone managed to get this dock to drive two 4K monitors?  If so what make monitors?

Accepted Answer

Yes - I'm running two Wasabi Mango 4k/42" monitors (LG IPS panels with Mstar electronics). Both are DP1.2 inputs (mDP->DP). The trick to making it work was loading the Intel HD application inlcuded with the Intel beta drivers. This allows you to turn off the SP panel, then bring the external monitors on one at a time (4k/29Hz is reported by the intel, but the actual sync is at 30Hz), then bring the SP4 panel back on. I could not get the panels connected with the MS Graphics Properties app. Note: I have not been able to force the monitors to sync higher than 30Hz each on the dock. The dock does not have the bandwidth to sync at 60Hz, but I was hoping for something in between. You CAN sync two external 4k monitors at 60Hz by plugging one into the dock and one into the SP4 mDP port - that was my configuration for ~2 months.

Question 2

Does it still act as a charger while in Use? Or does the standard charge need to be plugged into the dock?

Accepted Answer

It will act as a charger while in use.

Question 3

how does this dock connect to the surface pro 4? Is the dock all connected trhu the charging prot on the side of the surface.

Accepted Answer

Yes. It attaches to the charging port and charges the Surface while it is connected to the dock. At first I thought I would miss the dock I had for my Surface Pro 3, but I actually like the new dock on my Surface Pro 4. The dock is also very heavy, which helps it stay in place on the desk. It seems to be high quality.

Question 4

Does this work with surface 3?

Accepted Answer

The Surface 3 has a microUSB charger so it would not be compatible with this dock. However, the Surface Pro 3 and Surface Pro 4 share the same Microsoft proprietary charger that snaps magnetically to the pro versions. If you have the Surface Pro 3 you can use this, but if you have the earlier version Surface 3, then it is not compatible.
