daisy chain u2713hm and p2715q monitors

I have the dell p2715q monitor and it has a displayport OUT 

is it possible to plug a displayport cable in there and then connect it to the displayport IN of my u2713hm monitor ?

I tried it and the screen of the u2713hm monitor is all pink and unusable.

How can I connect both of these monitors to my so that they both display at max resolutions.

Now I have to settle connecting the u2713hm with HDMI but I am only getting 1900 x 1200 resolution on it.

Would a display port splitter solve my problem?
