Looking at a laptop and want to be sure it can support at least one external monitor at 4k resolution.  I want it to run the laptop display and at least one external monitor, both at 4k. Would be really stoked if it could run the laptop display and 2 external monitors, all at 4k resolution.

Will this one do that?  If not, can you suggest a laptop that would?

the geforce gtp 970M does support 4k http://www.geforce.com/hardware/technology/4k/supported-gpus
it should work both internally and externally
did not check if it is dual screen but i assume it is

the internal display is 3840 x 2160 (UHD)
which is apparently 4k-ish as well

whatever the laptop, grab the model of the graphic card and screen and you'll get your answer by googling

yes, the graphic card (gtx 970) of this notebook supports HDMI 2.0 which can output 4k video provided you get a true 4k external display and hdmi 2.0 cable.

But, the notebook has only one HDMI port and you can only output two idential 4k external display using a hdmi splitter like the one below.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

I currently run 2 external 4k monitors and would ideally like a new laptop to do the same: run 2 4k monitors and it's own display in 4k.

wow !

might be feasible using an external dock and a computer with a thunderbolt port. this one apparently does not feature one.

maybe this can be useful as well but i have no experience with these

not sure how/if that works... never tried it... i guess it emulates a separate graphic card, and all 3D rendering is performed by software

if you do end up with a working solution, feel free to post your config
