How do I add Monitor for Extended Display: Only one VGA Port

eliuri · 29 Oct 2018

OK....So these GE Force graphic cards should support two monitors---either thru VGA or DVI-->VGA adapter--- without my making adjustments in the BIOS?

I've never done anything in the BIOS, nor do I know how to. . Which is why I'm asking...

Can someone clarify that part of my question?

Yes. The plug adapters are not affected by the BIOS, not even seen. They are simply wiring changes from one type socket to another type.

The BIOS should not be an issue, automatically disables the onboard/built-in video. When logically thought about, a user-adjustable setting to do that will kill the use of the computer if the Add-in card were removed, nothing would appear on the screen to enable use hence the automatic part to restore use of the built-in adapter.

In the desktop PCs that I have known, adding a discrete graphics card disables the onboard graphics.

The dual graphics available on some laptops is a power-saving measure: the integrated graphics are used for applications that don't require a powerful GPU. Things switch to the discrete graphics when demanding tasks (like games) are run. nVidia's name for that is Optimus. As far as I know, no desktop machines support it. It also doesn't allow you to run integrated and discrete graphics at the same time.

You can have both onboard and discrete graphics enabled. I have one monitor connected to the nVidia card and one to the onboard graphics.

I can't argue with that. Sorry for the misinformation. I wonder how common that is?

I am currently running 2 desktops with Win10. One has a motherboard that supports integrated graphics with some CPUs, but my CPU doesn't support it.

You can either disable the internal GPU or keep it enabled in the bios. Being UEFI has zero to do with how the bios handles hardware.
