    I am able to connect one monitor using a HDMI cable.

    I’ve tried connecting the second monitor using the other HDMI port but it doesn’t work as it’s an in port (correct me if I’m wrong)

    I want to extend the monitors, not duplicate but for the sake of it I’ve tried to daisy chain using DP cable also tried HDMI and nothing.

    the purpose for multiple monitor connection is general use & work.

    I bought a type c to HDMI adapter and tried connecting the second monitor this way but nothing (Though i can use it to connect my phone to the monitor)

    How can I connect the 3rd monitor?

    Should I have bought a USB 3 to HDMI cable instead?

    Do I need an external graphics card? or just configure the graphics card drivers?

    Let me know if you need additional info about the system, Also if I should be asking somewhere else, please let me know,

    Thank you kindly for taking the time to read and help me out,

    Alan
