To begin, select the "Onboard VGA" option. In the Award BIOS, you must go to : Advanced BIOS Features. Note : "Primary display" is the equivalent of the "Init Display First" option present in the Award BIOS. This is no longer the case after changing these two options. Info : default (value : auto), the BIOS use the internal graphics card if there are no additional graphics card (PCI or PCI-E).īut, if an additional graphics card is plugged on the motherboard, the internal graphics card will be disabled by the BIOS. Note : "CPU Graphics Multi-Monitor" is equivalent to the "Onboard VGA : Auto / Always Enable / Enable If No Ext PEG" option present in the Award BIOS.įinally, click on the "Primary display" option (primary graphics card) and choose "CPU Graphics" (Graphics of the processor, so : Intel HD Graphics).
And the PCI or PCI-E graphics card : dicrete graphics devices In the new UEFI BIOS of Asus, you must go to : Advanced -> System Configuration Agent.Īs shown at the bottom of the screen, you must enable the "CPU Graphics Multi-Monitor" for supplying the 2 graphics cards (both) : Otherwise, the screen may remain black after restarting your computer. port of your motherboard instead of that of your graphics card. Now, your computer will use your computer's internal graphics card by default.įinally, save the changes by pressing F10 and don't forget to connect your screen to the VGA, HDMI. Now that the "iGPU Multi-Monitor" setting is enabled, you must configure the "Primary Display" setting to choose which graphics card will be used by default by your computer.Īs you can see, by default, this setting configured to “Auto” (automatic).Ĭhoose "iGPU" so that your computer initializes the internal graphics card (for example : Intel HD Graphics) by default, instead of using the graphics card connected in PCIE. Note : as this setting is disabled by default, the internal graphics card (integrated in your processor) is disabled when you connect a graphics card in PCIE (PCI Express). In this "Graphics Configuration" section, you will find an "iGPU Multi-Monitor" setting which allows you to add the support of the multiscreen (so : support the use of several graphics cards).Ĭlick on it which is disabled by default.
In the "Advanced" section of your BIOS, go to : System Agent Configuration. The "Enter Advanced Mode?" message is displayed. If your Asus motherboard BIOS looks like this, click on "Advanced Mode (F7)" at the bottom left. The BIOS will be reset (with default settings) and your PCI or PCI-E graphics card will work normally again. Turn off the computer by still pressing the power button, unplug the computer power and remove the round cell battery (which is on the motherboard) for 30 seconds. Find a monitor with a plug compatible with your motherboard (VGA, DVI or HDMI depending on motherboards models)
Which will require you to connect your monitor on your motherboard to get back into the BIOS to make the inverse manipulation. Indeed, once the modification saved, the PCI or PCI-E graphics card will no longer send at startup signal. Important : before putting the external graphics card as the default graphics card, make sure that you will be able to connect your monitor on your motherboard. Here are 2 examples of BIOS that will allow you to do the same thing. In short, depending on the BIOS of your motherboard, the necessary options may have different names. In some cases, it's necessary to force the use of the internal graphics card to use the PCI or PCI-E graphics card for something else.įor example : on a virtualization server, this technique allows you to use the internal graphics card (eg HD Graphics for Intel CPUs) and pass the PCI or PCI-E graphics card to a virtual machine using the VGA Passthough.
