OT: Getting Higher Resolution from interface

[Samir Faci]

This isn't exactly on topic since I don't think it's a Linux issue as much as a hardware issue.

I have a Dell m3800 which had a HDMI port and a thunderbolt connection that allows me to connect an external device.

The HDMI port as far as I can tell is limited to:  1920x1080 (or at least Ubuntu limits it to that ).

The thunderbolt to DVI adapter also limits my external monitor to the same resolution even though it supports 2560x1440.  

I ran across these quirky devices from apple such this one ( http://www.amazon.com/Kanex-DisplayPort-Thunderbolt-2560x1600-resolution/dp/B0045I85GY/ref=sr_1_1?ie=UTF8&qid=1436038550&sr=8-1&keywords=thunderbolt+2560) 

that supposedly gets me a higher resolution by taking up the thunderbolt + USB port to get the higher throughput.  Has anyone tried using this on a PC based 

laptop?  They claim it was designed for a macbook pro, though I'm assuming that's mostly because thunderbolt aren't that common on the PC landscape? (Or at least as common as they are on apple).

Any thoughts?
