Windows 10: Two GPUs and two monitors, how does it work?

Hi, today I got myself a new computer. It has space for 1 more GPU, the current GPU doesn't have more than 1 HDMI port, so I was planning on connecting my secondary monitor (since I don't use it for anything else than a web browser and some streaming stuff) to another GPU.

GPU is fine.... Bios is fine.... Why can't Windows 10 detect my second monitor?

Now my second monitor isn't even cloned... no signal... windows 10 cannot detect a second monitor and suggests a different GPU... My GPU can support up to 3 monitors... again... ran every diagnostic on my BIOS and GPU know to man. Thank you for your assistance...
very irritated by this simple problem.

Hi,

This issue may happen if the GPU is taking more time to display the graphics on your monitor and if the graphics card or driver is already problematic.

As an initial troubleshooting step, try to uninstall then reinstall the graphics driver and see if the issue will persist:

• Press Windows key + S and type devmgmt.msc.
• Press Enter.
• Expand Display adapters.
• Right-click on your graphics driver.
• Select Uninstall.
• Click OK.
• Restart your computer.
