onboard video is not supported when a card is in the slot. This is an un supported configuration. You can use 2 monitors on a GT1030 but you need an HDMI to VGA adapter and dvi for the other monitor. [URL]  
[IMAGE]   Hi! I recently upgrade my pc with some new ram and a graphics card. I have a Windows 10, Dell Optiplex 980, Intel i5, 16gb Ram.    I got the NVIDIA Geforce GTX 1030 graphics card. The graphics card has a DVI port, and an HDMI port. I got the necessary adapters to connect my dual monitors with VGA to the DVI and HDMI.   The problem is that when both monitors are plugged in to the graphics card, it’s like the system doesn’t know which monitor to display the apps on, so they jump back and forth. One screen goes black, it jumps to the other screen, then that screen goes black, and it goes back to the other screen.    I think the only solution is to run one monitor through the onboard integrated graphics, and the other through the GPU.    I can see that a lot of motherboards allow users to easily open BIOS and enabled onboard graphics which is disabled automatically when a new graphics card is installed.   The issue is, when I open my BIOS, I don’t see the option to do this. My BIOS seems to be different than everyone else’s that I have seen and therefore I can find the option to enable/disable onboard graphics.   I’ve attached a picture of what my bios looks like for reference.   My motherboard is: Manufacturer: Dell   Product: 0CT22T   Serial Number: ..CN7360413N00I0   Version: A04   So my questions are:   I really appreciate all the help I can get. I’ve spent all day trying to fix this issue and don’t really know what else to do. Once again thank you very much.   Thanks, Jacob
