Using Surface Pro 3 (SP3) with Docking Station.. Have two new DELL U2415 monitors in, preferably, daisy chain mode. Three displays: SP3 display is number 1, U2415 monitor is display number two and the second U2415 is display number 3. Have tried several SP3 docking stations and can NOT get this configuration to work (from docking station). That is, connecting the Dell supplied MDP cable from the docking station to monitor number 1 (display 2) , and daisy chaining to my other U2415 (monitor number 2, display 3) from there. I CAN however daisy chain, very nicely, mind you, if I connect the MDP cable directly to the SP3. Has any one solved this dilemma: Have the configuration work directly from the docking station rather than the SP3? The three display daisy chain mode works fine only if display 2 is connected to the SP3 directly, and display 3 is connected to display 2. Microsoft agrees this is not the way to use the docking station. They say daisy chaining should work from the docking station. And have been generous to allow me to try several docking stations. Is there a 'special' branded MDP to MDP cable, or MDP to DP cable that works better than the Dell supplied MDP to DP cable to accomplish this seemingly simple configuration? A link to that branded cable will help. I'll gladly pay a few dollars to get a cable that allows the daisy chain to work (from docking station) if one is identified; and verifiably works for daisy chain mode from the docking station. As mentioned daisy chain works only from SP3 at the moment.
