My cpu does have integrated graphics, how can I change this so that it will work on my mobo monitors
As i said there is absolutely no reason to do that if you have a dedicated GPU. furthermore if you are attempting to use a dedicated card and the integrated graphics at the same time that is not possible.
But if you insist simply open up the BIOS when booting while plugged into the dedicated card. change your integrated graphics settings to primary save turn off the computer switch the cable and reboot
