Thee monitors P8Z68-V LX, integrated gfx and gfx card.

Update 2020-May-1st: As of version 2.10.1208 BIOS the Primary GFX setting has been removed and 3 screens should work automatically.

Original Post:

To get more than 2 monitors on the P8Z68 you can use the display connections on the motherboard in addition to your dedicated gfx card.

To make this happen, go in to BIOS and ensure the following settings are set:

1. Primary GFX: iGFX (this sets the primary display to be connected to the motherboard, yes, unfortunately this has to be set and catches people out)

Note that you can only use the HDMI or DVI connection on the P8Z68, but not both at the same time, you can use the VGA in addition to either the HDMI or DVI.
