Can't find this anywhere.

Can Haswell power multiple 27" 1440P displays at full resolution using the onboard GPU?
If so, how many?
Does anyone know of any plans for a Haswell motherboard with multiple DisplayPort connections?

HD Graphics 4000
No update on the new Ivy Bridge CPU’s would be complete without mentioning the improved on-board graphics power.

They offer a major step up in performance over previous integrated graphics chips and make gaming without the need for a dedicated graphics card a reality for some.

For multi-screen scenarios though there is little benefit as to achieve the high number of monitor outputs required we are forced to head down the separate graphics card route.

The new Ivy Bridge motherboards have the capability of supporting three screens directly without the need for an extra graphics card, however the outputs are 1 VGA, 1 DVI-D and 1 HDMI which means it would be impossible to support 3 analogue (VGA) or 3 digital screens simultaneously. You would need to mix and match connection inputs between your screens which would leave you with comparatively different brightness, contrast and colour depths across your screens.

To achieve 3 or more screens of the same connection type then you will still require separate graphics cards.
