Adding a 3rd monitor: DH55HC

Hi there,


Hope some one can help:


Want to add a 3rd monitor to a working system I just built, and working just fine.




Intel DH55HC mohterboard

Intel Core i3 3.06GHz

4GB DDR3 1066


Windows 7

Monitors: Acer H203H B  (Qty:3)


I'm currently using the integrated graphics ports, VGA and the DVI-D ports for two monitors (extended mode).  I tried to add another monitor using a USB adapter (Arkview model USB-DH88) but it does not work at all.  I can hear the Windows sound when I connect the USB adapter, and can also be heard when disconnecting it, but that's it, no video. So I'm thinking of other solution, as stated next.


I want to know if its possible to add a PCI video card and connect my third monitor without loosing the onboard video connected monitors.  Please note: if I add a PCI Express 2.0 x16 in the appropiate port it appears that the on-board video ports will not work (at least I couldn't make it work, therefore, if this configuration should work, please let me know how to do it, BIOS?  The pdf manual from Intel is not specific about whether I can use both -on-board and PCI Express 2.0 x16, or why the on-board deactivaes in the presence of a PCI-E_2.0_x16).  So I thought of adding a regular PCI video card (I don't care if the regular PCI video would not be usable for intensive graphics, I just want to be able to see my day-to-day spreadsheets), like the Sparkle SFPC84GS256U2LP GeForce 8400 GS Video Card.


Appreciate your help.
