Predator X27 Flickering HELP!!!!!

Hi everyone, first post here. I bought myself a Predator X27 for christmas. I am experiencing blinking issues with this monitor. I have downloaded all the latest drivers and have a pretty decent PC I9 9900k, GTX 1080ti card, Asus z390 motherboard.

I have not changed anything from the stock setup apart from setting the refresh rate to 120. It was originally on 60. Both rates the monitor was blinking. I am running the DP cable I received with the monitor into the Graphics card.

One other thing I have noticed is that the fan is alot more quiet than I expected. It doesn't even sound like its on???

Can anybody shed any light on what else I can try?

Thanks
