[CentOS] Video projector vs. onboard video card

I have a CentOS 7 desktop client installed on an old Dell Optiplex
computer with an Intel video card integrated into the motherboard. The
card has a single VGA connector, and the 19" monitor is connected to it.

I wonder how I could connect a video projector to this computer while
keeping the monitor, in a mirroring configuration, e. g. output is the
same on the video projector and the monitor.

Do I have to replace my onboard video card by something like an NVidia
GT710 graphic card with two video connectors ? Or is there a different
solution for this?
