Is it possible to have dual monitor output both monitor using dvi One port on graphics card one on motherboard?

Yes, it is possible to have dual monitor output using one DVI port on a graphics card and another from the motherboard, but it depends on your system's configuration. If your CPU has integrated graphics and the motherboard supports it, you can enable both outputs in the BiOS/UEFI settings. However, this setup may not provide optimal performance for graphics-intensive tasks, as the monitors would be using different graphics sources. Always check compatibility and settings for your specific hardware.
