No it's not the motherboard. It might be a bad displayport cable, or bad ports on the card or monitor (or both the monitor and card, but hopefully not).

Its a long shot, but try swapping PSU's.  HDMI can be more electrically noise resistant than DP.  Another problem could be bad grounding in the wall socket if your other PC is in a different location.

actually I just changed psus yesterday from a 400 watt which would not work at all with rtx 2060 and i5 9600k to a 850watt even if I did change my power supply and it worked is there a way to fix it so my 850watt will work

If its caused by electrical noise, no.

Depends on what power supply it is, a 450watt good psu is gonna be better than a 850w generic thrash psu that will blow up if you load it anywhere near it's rated max capacity.

A better quality PSU is likely the fix.

 

What model is the 850w?

I meant the displayport cable, if the gpu works with hdmi chances are that the pcie power cables it's using are fine (maybe doublecheck that the cables and the graphics card are fully seated in even tho that shouldn't be it).

its fully seated would getting a higher quality cable work aswell?

Unless you are running very long display cables quality doesn't make a difference (digital signal). Trying another cable would be good in case the one you have is completely dead.

tried multiple cables as long as my graphics card isnt broken so i can re sell  later on when I upgrade its ok if I need 2 monitors ill use dvi
