Omen 27 Inch Monitor not working on DisplayPort

HP Recommended
Omen 27 Inch Monitor
Microsoft Windows 10 (64-bit)

Hello everyone.

Yesterday i bought the Omen 27 Inch Monitor and wanted to plug it in as soon as possible to enjoy the 144/165Hz experience, but i can't, and here's why:

The monitor works 100% on HDMI without any problems, but as soon as i switch it to DisplayPort it doesn't find a connection to the computer and says "Input Signal Not Found", i've searched a lot on the internet, tried to swap cables, turn it on/off, new drivers and everything but it still doesn't work.

I really don't know what is going on but i would apreciate some help if someone actually knows how to solve this problem.

Much thanks and have a great day!
