In order for all four boards to behave in the same way, they all must be connected to the same input type on a monitor, due to the precedence of the video outputs.Īlso they all must have identical video cards, or at least the same video card in the same PCIe slots. The primary selection in the OS does not affect the UEFI.

Is there any way to select a video source as the primary? You can do that with software in the OS, but not in the UEFI/BIOS. For example, an EVGA 960 card I use follows the DisplayPort, HDMI, DVI-D, DVI-I output precedence. Have you ever used a multiple monitor setup, two or three monitors, into one video card? What happens when you use the UEFI/BIOS UI? Is the UEFI display shown on all of the monitors? No, it is only shown on one monitor. The monitor being used can also have its own precedence about which video input it prefers as the primary, but when using multiple monitors the difference is usually due to a different set of inputs. The iGPU should be enumerated before the PCIe slots during post, but what video source is used for the UEFI display depends upon the video cards being used and which outputs are used. So the card in slot PCIE4 will have priority over the card in slot PCIE3, etc. The PCIe slots are enumerated (initialized) during POST from the bottom up, meaning the card in the highest numbered PCIe slot has first priority. The video source used for the UEFI can seem to be almost random, but it isn't. But the VBIOS of the video card can be different, if it doesn't have all these outputs, and if it is programmed differently. The precedence for the video outputs usually is, from first to last, DisplayPort, HDMI, DVI-D, DVI-I, and VGA. When using multiple video sources/cards, including the iGPU, which source and monitor that is selected for the UEFI/BIOS display depends primarily upon which video output is being used, and also the video sources. Have you changed the Share Memory option in the Chipset Configuration screen?

That option is disabled by default on non-mining boards, but might be different in your board.

The only option to 'disable' the iGPU is the IGPU Multi-Monitor option in the Chipset Configuration screen, set to Disabled. It will always be supplied voltage from the board to some degree. There is no way to completely disable or turn off the Intel iGPU on any mother board. When multiple video sources are being used, the UEFI display source is dependent on the output configuration, the video source initialization precedence, and things beyond our control. Which monitor has the UEFI/BIOS display depends mainly upon the video output being used on a video source. Short answer, the iGPU is never completely disabled, the CPU does not allow it.
