On G41 motherboards, can I use the onboard DVI display and add on graphics card DVI display at the same time?
Due to Intel G41 chipset limitation, when you use add-on graphics card VGA output, the on board HDMI/DVI output is disabled. You can only use onboard D-sub display and add-on graphics card at the same time, since PCIEx16 share SDVO (Serial Digital Video Out) with on board HDMI/DVI.
