Laptop to connect 2560x1440 external monitor

[monkeys]

Hi, I have asked before and am looking to connect the monitor to a Laptop. Ideally less than 2kg in weight and HD screen on the laptop so I can carry it around and hook it up to a high def screen so using them for work. Any suggestions as I am unable to find details anywhere.

An ultrabook will be ideal as they are nice and light.

At a guess any laptop/Ultra book with a Display port, HDMI 1.3 upwards and finally a dual link DVI-D/I port, however l would double check with any manufacturer to ensure that their kit can do it.

Yes, Displayport is prob the way to go but I do not know of any DL DVI laptop.

Just wondering if anyone has any knowledge ad manufacturers are really vague...some not sure.
