6.1. Enabling Graphics Between Motherboard and Discrete Graphics Card

Some customers may want have more flexibility with rear video ports by using some onboard ports AND some ports on the discrete graphics card.  Maybe they are adding more monitors, or maybe they need a combination of ports because their monitors are limited on port choice.  However when attempted they may discover only one set of ports are working.

To correct the issue and allow use of both sets of video ports, follow these procedures:

1)  Restart and start pressing Delete while the Transource logo is displayed on screen.

2) Once in BIOS, look for the Advanced tab at the top and select it.

NOTE: On some BIOS configurations, you may need to press F7 to get out of the graphical interface and show this option.

3) Under the Advanced Tab look for System Agent (SA) Configuration and select.

4) Inside this menu option, look for Graphics Configuration

5) Inside of Graphics Configuration you will find several options you can configure.  The main choice that needs to be changed is the iGPU Multi-Monitor set to Enabled.

However here is a description of the selections and how you can change them.

Primary Display > Auto = PC will choose which set of ports to activate first.

                             Discrete = Discrete graphics card will activate first and show video before onboard.

                              IGPU = Onboard graphics will activate first and show video before discrete card.

iGPU Multi-Monitor > Disabled = Only the Primary Display will display video (see selection above)

                                     Enabled = Allows use of both onboard and discrete video. 

6) Press F10 to save and exit.  Allow the PC to reboot.

Once the PC boots into Windows, a new device maybe found.  After drivers are loaded, the PC can use video ports from the onboard graphics and the discrete graphics card.
