Is it possible to have a triple head (3 external screens) setup with an L530, using the integrated Intel graphics chipset?
I read that you can use the Mini-DP, VGA and laptop screen at the same time with the L530 (I can only do the former 2 with my L520 - tested to confirm). Is there a way to do this with 3 external screens, preferably with digital outputs, too?
I'm aware of the ThinkPad Mini Dock Plus providing the interface for this (2x DP, 1x DVI), but there seems to be some ambiguity over whether all three of these work with the L530.
I have seen the link for the nVidia chipset (NVIDIA Optimus - ThinkPad Multiple Monitor Configurations), but that didn't help to answer my question either.
If someone could clarify whether 3 *external* screens are possible on the L530 with/without the dock, it would be appreciated.

BTW, the L530s we may be buying would be fitted with Intel Ivy Bridge CPUs - i5-3210M.
My understanding is that the Ivy Bridge chips support 3 screens, up from 2 on the previous generation Sandy Bridge chips.

According to the PSREF for the L530, it only supports dual independent display with the integrated Intel graphics:
"Intel HD Graphics 3000 or 4000 in processor, supports external analog monitor via VGA DB-15 and digital monitor via Mini DisplayPort; supports dual independent display;
Maximum external resolution:
2560x1600@60Hz (DisplayPort via optional Mini DP cable);
1920x1200@60Hz (single-link DVI-I via optional Mini DP cable); 2048x1536@75Hz (VGA)"
You'll also see in the PSREFs that the L530 is compatible with these:
ThinkPad Port Replicator Series 3 with USB 3.0 433615W
ThinkPad Mini Dock Series 3 w/ USB 3.0 - 90W 433715U
TP Mini Dock Plus Series 3 w/ USB 3.0 - 90W 433815U
TP Mini Dock Plus Series 3 w/ USB 3.0 - 170W 433835U

So even with the Ivy Bridge chipset (with the 4000 series graphics), the extra video channel isn't supported?
If we wanted to go with 3 external screens, I assume we would either have to go with the T530 then, if we wanted a 15.6" screen + similar spec?

The 4000 only supports dual independent display as well. You would have to use a dock to have more than that (compatible docks posted above).
The T530 with the NVIDIA Optimus does support three independent displays.

Thanks again, Ron.
"The 4000 only supports dual independent display as well. You would have to use a dock to have more than that (compatible docks posted above)."
Does that 3 screens could be used when docked?

I'm sorry, Traktion, I was incorrect about the dock statement. You can still only have 2 displays, even with the dock, with integrated graphics.
