AVG probably refers to the HDMI or DP output.

Yes, the CPU will output an image signal to these. A separate graphics card is therefore not necessarily required.

I also recommend contacting customer service and having the name/phone number/email deleted from the question.

As everyone can view and answer the questions here, I would not enter any telephone numbers or e-mail addresses here.
