So I have two monitors, one linked via dvi to my gtx 970, and second one that only includes vga port, thing is my 970 doesn't have vga port, but my mobo does, yet the ports are turned off because there is a gpu installed, I've heard that you can force the mobo ports to work with gpu ones simultaneously, yet i have no idea how to do such a thing. Most ppl online suggestt buing adapters or special cables, thing is I can't get one near me, and buing one online would take weeks.
Edit: My mobo is Z97 extreme4 from Asrock. And gpu Is from Gigabyte.

Some motherboards will disable the IGP by default when a GPU is installed. There should be an option to select if the IGP is Auto / Primary (enabled at boot) / Secondary (can be enabled by the OS) / disabled.

I haven't tried splitting displays between GPUs in over 15 years and back then, displays connected to the secondary adapters had no hardware acceleration. Since you likely already have the VGA cable, you can always try it to see if that works well enough for your purposes. The only thing that costs you is the time to look up through the BIOS to find how to enable the IGP and install the OS drivers for it.

try using a hdmi to vga or dvi to vga adapter, there rather inexpensive and i am currently using one as well. plugging the vga into the motherboard means it will be using the onboard-graphics i think, not sure. the graphics card receives graphichs true the mobo which the gpu will then process and send the processed pictures to the ports to the back and not back true the motherboard to that port.

Using a simple adapter is way easier. But when connected to the Mobo will it then not use the onboard graphics?

Many modern gaming laptops connect their display to the IGP and stream video from the GPU over PCIe so the GPU can be shut down when not in use and conserve power, not sure what bits of software are used to make that happen. Under normal circumstances, the IGP and GPU drive the displays attached to each of them.
