You mentioned that you were able to make 256x240 120hz on your GTX 1070 through hdmi , in theory, could nvidia intel or amd enable such low resolutions on the displayport out through drivers? or will displayport never be able to carry such a low pixel clock signal?

Theoretically it could be done, but it would be out of spec, and the adapter would have to support it as well. The problem is a low pixel clock might be considered an inactive signal. Usually low resolutions are implemented with double clocking and/or double scanning because of scan rate limitations. They could implement that as well, but there isn't a way to specify that in the EDID.
