got my new screen yesterday (Acer XF270HUAbmiidprzx), plugged in and Display port doesn't work :(
hdmi works but I'm limited to 70hz max
this is what I tried:
- both ports on the graphics card (vega 64) , made sure cables are in properly,
- left the screen without power to drain - some ppl on the internet were suggesting that,
- installed the newest drivers for the graphics, tried with and without fresync (though this is pointless as I should be able to see the BIOS/Post)

I've got a second display port cable to test tonight, and a display port to divi-d cable too. I don't have another screen with display port to test.

any other suggestions?

I love this screen, no dead pixels, amazing colors, but at the money I've spend if it doesn't work as intend it's gonna be a return

Good one. Hopefully a silly question but you did select DP input on the OSD, didn't you?

it's a legit question :) , I did select DP (I also played with the auto detect On and Off, it cycles through the ports trying to detect a signal), also tried the lower version of DP -> 1.3 and then flipped back to the highest available 1.4 if I recall.
 
Have you tried the driver for the monitor itself? I've got a monitor with a display port and needed the driver to get the full 144hz (different to your problem but might solve it). It could be a dead display port, I've seen it happen before.
