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

You’re right.

1. This machine only has a single HDMI output port. This means you have the AIO’s display and one more external.
2. Try the USB 3.x to HDMI cable. Be sure to buy with full return privilege since it’s unsure if it will work.
3. It is not a software configuration issue.

4. An external graphics card on USB 3.x is known to work but gamers tend to learn these are too slow. There is no mention of intended use.

https://www.dell.com/community/Inspiron-Desktops/Two-additional-monitors/td-p/7744225 tells how it’s done. Certainly worth a try.
