Would this laptop support 4k output?

I am using an m18x r1 with Xfired 6970ms.
I was wondering if it would output 4k from miniDP. I know thi sis a noobish question, but I am a bit confused. It is listed in the specs as a max digital resolution as 2560x1600, as well as the 6850 that the 6970m is based on. But apparently the 6850 will output 4k. So will this do it?
And no, of course I'm not looking to game at 4k. Just regular use.
There's a Philips 40" 4k monitor coming out, and I think that would make the perfect screen for working on, and I'm curious if I can use my laptop on it.

 

Those GPU's are not powerful enough.

Also, there is an entire sub-forum dedicated to the M18x.

They sure as hell are, I've seen 4k on less. I'm not going to game on 4k. At all. This is pure work purposes.
I want to drive a 4k desktop for a workspace. I'm not asking if they are powerful enough, but whether they will output 4k at all.
Besides, it's a VA panel, it may not be the best for gaming and have ghosting.
I'm building a new desktop, but not for quite a while.

 

Oh, well I assumed you wanted to game, as you have an Alienware. My bad.

 

It's not even really good for 1080p anymore sadly. Needs a gpu upgrade, and I just don't want to spend the money on that ATM.

 

Sadly 2560x1600 is the max resolution the 6970m can do. I'm not 100% sure on this, you can try it through displayport, but I'm pretty sure the architecture only allows up to that resolution.

 

If you upgraded to a later card you should be able to.

 

It may "kind of" works.

Interesting so an MST monitor does work, though if I was shelling out that much for a display I would want a card to match it.
