Brand new 7900xt xfx no display

Just installed a new 7900xt xfx 310 merc and it powers on fans lights etc. no display out of any port. Monitor is good tried hdmi and display port cables. Tried both pci e 4 ports. Not a new system so I have no idea. Removed cmos to reset bios settings. Not sure what else to try other than return and wait a month to get a new one

Edit: update: got a new card. Still no display so not sure what the issue is.
