T450s or X1 Broadwell @ 2560x3200 ?

I'd like to drive two external 30-inch monitors, both at 2560x1600, to create a contiguous desktop of 2560x3200.  The T410s allows this, as long as you use an Ultradock Pro, but the X1 Haswell can not.  

 

Can the T450s or the X1 Broadwell support such an external resolution?  If so, which docking solution is required, because there are not two HD video outputs on the laptops themselves?  (Preferably I'd like to use a pair of displayports or minidisplayports, but my 30-inch monitors have HDMI too if necessary).  

 

I have purchased many laptops from Lenovo that have had to be returned because they failed this test.  Each time, several salespeople had assured me that the laptops were capable of 2560x3200 external resolution.  So, I'm reaching out to the real experts on this forum for reassurance this time around.  Thanks guys....

OK, first to apologize for my math.  My two adjacent 30-inch monitors are running a contiguous desktop of 5120x1600.  I purchased a T450s along with an ultradock pro, and using dual-link displayport cables, I can spread a desktop across all three screens at native resolutions.  Meanwhile, the keyboard is back to being excellent again, and the touch screen is clear at 1920x1080 and more responsive to touch.  It is fast at i7 and 12G ram, but windows 8 sucks up nearly 50G of the hard drive, so go big with your SSD.  Total cost was about $3K, while the retina macbook pros are $1.5k or $2k, and they can also drive a pair of giant resolution external monitors (4K too I think).  I like the T450s better, but not $1k better.

If latency isn't a big issue, maybe a USB 3.0 to DisplayPort adapter will work?

Re: T450s or X1 Broadwell @ 5120x1600 ?

Thank you.  Good idea, that would likely work too.  The main point was that I was unsure that a T450s could drive a contiguous resolution of 5120x1600 (two 2560x1600 monitors side by side).  I now know it can, although the icons are soooo weeeenie!  My eyes are getting too old for such high resolutions.  I'm sure I'll figure out how to fix that weenieness though.  The t450s is a great laptop though, they fixed all the horribleness with the trackpad and the function keys.  For $3000 it is too expensive, same price as two macbooks, but I think the T450s as good as you can get for a 14 inch laptop.   (The macbook does not have the useless touch screen though, but it does not need a docking station and that's part of the $3000).  Anyway, I digress, I just wish the T450s folded back on itself so you could use it as a huge ugly, chunky tablet.

There's always the non-touchscreen option if you want to save some cash and avoid getting tons of smudges on the screen. And save some weight too. Still not a fan of the hybrid volume keys; dedicated volume keys are still the way to go. The 6-row layout is still horrific IMO.

I don't see a dock for the T450s here yet:
http://support.lenovo.com/us/en/documents/pd014572
So I don't know what sort of display output configuration it'll support.

If a second external display is the only thing you plan to use the dock for, a USB 3.0 adapter is probably more cost-effective (plus you can use it on a different machine).

The dock station pages are not updated for the x50 series yet; but look at the http://shop.lenovo.com/ca/en/laptops/thinkpad/t-series/t450s/#tab-accessories_-_services accessories tab of the t450s itself, there's the ThinkPad Ultra Dock .

Horrific is a bit strong, but I'm likewise not a fan of the current 6-row layout.

T420s was the last ThinkPad to really get it right.
