Why can't I access the "image quality" menu on my AOC G2460P monitor?

I bought this monitor and I can't access this menu. Please help.

Image quality options are unavailable on some monitors when you use hdmi or dvi inputs. They are digital, and you have nothing to adjust here. what does the manual say?

I am using a dvi input so then would it work if I switched to using a displayport input? and the manual says nothing about it not showing up and the manual says that I would be able to adjust the picture sharpness and some other stuff but adjusting the picture sharpness is the part I care about. and I also can't access the overdrive option in the Luminance menu. This is the manual:

Some image options can only be adjusted in analog mode, and that would be vga. Hdmi, dvi and display port are all digital.
