So installing the latest AMD Beta drivers solved the issues I was having with enabling Freesync and setting the refresh rate to 144hz, as I said before there is no flaw with the screen itself, it's fantastic. Right now the plan is give it a day or two and if I decide to keep the screen I'll contact BenQ to arrange the RMA as it is indeed on the V001 firmware.
I had a lot less time than I would have liked to play around with the calibration and test some games but I managed a few pics here:

I should have more time tomorrow to really get into it.
