I have purchased a Precision 5510 Intel® Core™ i7-6820HQ (Quad Core 2.70GHz, 3.60GHz Turbo, 8MB 45W, w/Intel HD Graphics 530) with the 4k display option.
I am having trouble in getting the video signal out at the native resolution of the external monitor I would like to use: U2713HM(2560 x 1440). I am using the HDMI output for external monitor and when trying to set the external display resolution I only have 2 options (for high resolutions)in the configuration panel: 1920X1080 and 3840X2160. No other options between these two.
I did a little researching on the U2713M and found this document.
The prime, or optimal, display mode for the Dell U2713HM monitor is listed as 2560 x 1440 Dots per Inch (DPI) at 60Hz. This maximum resolution is only available using either the DisplayPort or DVI dual-link inputs.
The following list shows the available inputs on the Dell U2713HM monitor and the maximum resolution for each:

Thank you for your input. Something strange happened today. I have used another HDMI cable and the the native resolution(2560 x 1440) appeared in my option list but it was not the recommended resolution(1920x1080). The 4k resolution disappeared from the option list. I am still getting the 4k option when operating in clone mode for multiple displays but the image on the u2713hm gets chunky, especially for texts.
I have another question: What would be the cheapest option for a docking station compatible with my laptop that would support a dsp or dvi output and several usb 3.0 connections?
