How to Enable Onboard Video in ASUS
By C. Taylor
Many ASUS motherboards come with an onboard video adapter, so you do not need a separate graphics card. If you ever installed a separate graphics card or tweaked settings in the basic input/output system, then the onboard video can be disabled. Enable it again by booting into BIOS and adjusting the video settings.
Boot up or restart your computer.
Press "Delete" when the ASUS logo appears on the screen. Continually pressing "Delete" during bootup does not harm anything and ensures the key is pressed at the appropriate time. See a prompt saying "Entering Setup," which is BIOS.
Press the right-arrow key until the top menu item, "Advanced," is highlighted.
Press the down-arrow key until "System Agent Configuration" or "Chipset" is highlighted, depending on which ASUS model you own. Press "Enter" to access settings.
Select either "iGPU" or "IGD" and press "Enter." On some models, you are also presented with additional options, such as "PCI/iGPU" or "PCI/IGD." Selecting these options enables your onboard card, while still offering support for add-on cards. This might be desirable when setting up multiple monitors on your computer.
Select the "shared memory" allocation, if the option is presented. Your onboard video uses part of your system RAM, so this option delegates the amount used for the video. The higher the number, the better performance the onboard video achieves. If you have very little system RAM, then selecting the highest value degrades your overall system performance. There is no hard-and-fast rule for this value; you may have to experiment to achieve your best results. This depends on the amount of system RAM, the programs you run, and the kinds of graphics and video files you use.
