W550s and 90W Ultra Dock drive four 1920x1080 monitors via 2 x DP1.2 daisy chains?

I'm trying (and failing) at driving four 1920x1080 monitors vai two DP 1.2 daisy chains. Three monitors show up as available. The fourth does not. Is this not possible? If I'm using both DP ports can I also use one of the HDMI or DVI ports to drive the fourth monitor instead of daisy chaining it?

 

Setup:

 

W550s (Model 20E2CTO1WW)

ThinkPad 90W Ultra Dock

 

One DP cable to a Dell U2414H

-- then daisy changed to a Dell U2412M

 

One DP cable to a another Dell U2414H

-- also daisy chained to another Dell U2412M

 

Both U2414H monitors have DP 1.2 enabled.

 

Thanks,


Sam
