Just purchased 2 Dell 2515 monitors, generally very impressed but notice that the colours are different between DP and HDMI inputs .. especially noticeable when I'm extending a screen over them - monitor settings are identical.

Any ideas on how to fix this?

Seeing as they support DP passthrough I thought I might try to connect them to my laptop (Dell 7740) via a single DP cable (Rather than using DP + DVI/HDMI) and daisy chain them - this might resolve the colour issue and also reduce cabling. I can get both monitors to mirror each other but not extend a desktop across them. Again, ideas?

Thanks!!
