Without checking the specifics of your motherboard, it is likely that using the Radeon card disables the onboard graphics.
If you want to use two monitors, put both of them on the Radeon card.
Also, check the documentation for your motherboard, or check the BIOS settings on the board for video configurations.
And, I am moving this post to the graphics forum.
i only check the processor to mobo
so should i use HDMI port for my other monitor?
the bios settings on video config is in auto.
im sorry im just new on posting questions on a community
You can use the ports on the Radeon card, or the ports on the board (without the Radeon card plugged in).
On the Radeon card, use the vga port for one monitor, and the hdmi port for the other (assuming the cards has both a vga and hdmi port).
yes it have, thanks for the answers and suggestions
