Hello.

I just received my 2015 MacBook Pro 13" and a Dell 27 UltraHD 4K Monitor - P2715Q. I am having problems getting the Dell to accept a signal from the mac using a TB cable to the mDP on the monitor. I ended up using a TB to HMDI adapter which works and gets me some of the HiDPI resolutions but it does not get the full 4K resolution.

Is there a different cable method I should be using or dock?

I am running Mac OS 10.10.5 Yosemite with an Iris Pro 6100 card.

The Dell has HMDI, DP and mDP ports. It has a native resolution of - 4K 3840 x 2160 ( DisplayPort: 60 Hz, HDMI: 30 Hz ) - Tech Spec's here - http://www.dell.com/en-us/shop/accessories/apd/210-adof

I am using SwitchResX to attempt to get the full 4K resolution, but no success yet.
