display port problem 3090fe

[bean5k]

So i got a 3090 fe last week all working fine in my system using the display port.
swapped it into my new pc i build last night and none of the display ports are working but HDMI is working...

new pc spec are:
5800x
32gig corsair ram 3600
msi b550

i know the cable and monitor are working fine because my 1080ti works fine

ive tried all 3 ports and drivers.

Yes tried 2 cables the one is plugged into my 1080ti at the mo and working fine, if I unplug and put into 3090fe nothing no signal into monitor
but the HDMI is working fine with the card..

What's strange is the display port was working fine before I moved it into new pc.

update: i just popped the 3090fe into other pc using the DP and worked for a bit....windows logging screen popped up! after logging in screen went black

maybe should RMA it?
