My pc detects a ''phantom'' monitor (bios, screens, motherboard, graphics)

[Boosane]

Hi everyone, I purchased a new monitor today and my system is STILL recognizing my old Monitor. In essence, it still believes I have the old monitor plugged in as well. I go into device manager and uninstall the old monitor but it eventually comes back again. However, when I plug the monitor into the motherboard instead of my graphics card, it's normal...thank you.
here's a screenshot.

Remove the internal graphics card in BIOS.

Does the computer allow you to right click and delete that monitor in control panel? Also check for monitor software added while in control panel .
