Thank you. I am currently running 2x 2560x1440 using the internal mini DP and the Onelink Pro's DP.
I also tried daisy-chaining the two monitors (Philips 272P) to the Onelink Pro's DP, but i could not get the displays to show up as separate devices in Windows, I am only seeing the same image on both. But it works OK as it is, I just have to connect one more cable.

Yeah, it's not a big issue not being able to use daisy chain, but as I understand this, it should have DP 1.2 http://support.lenovo.com/en_SE/product-and-parts/detail.page?&DocID=PD029981
Desktop extension works fine when I use two different displayports, it is just when I use daisy chain that they only appear as one display in the display properties.

I cant get max resolution (1440p) on X1 carbon (3443CTO) and Dell U2713HM. I am going through to the dual link DVI port on the monitor and have updated all drivers.
Reading posts on this forum suggests that the Intel HD 4000 driver used by the X1 carbon should support 1440p?

I've tried SO hard to figure this out myself but I'm afraid I need to defer to your superior skills. I have an X1 Carbon with the 1440p laptop screen. I also have two 27 inch 1440p external monitors, and I'm desperate to get all three to work at native resolution as you have.
One monitor works fine - mini-DP to DP, but the second external monitor via HDMI gets no signal and isn't detected by the graphics options. I have the USB 3.0 dock with its awful 2k down-sampled max. resolution via DVI.
I have a brand-new HDMI to DP cable, which surely isn't duff out of the box...? I will try later with a pure HDMI monitor and HDMI cable, but any ideas please?
Thanks so much!

Wow, thanks for the quick reply.
No: the monitor is DP and DVI only. Would it work HDMI cable with a DVI adapter on the end? I have one at home I can try tomorrow.
Any idea why it "needs" to be HDMI-to-HDMI to work?
