Is there any reason my 3rd monitor (Radeon R9 270X card) wouldnt work after I installed a new motherboard replacement? 2 of the 3 are working but the other is not... Any ideas?

I remember when I put this setup together a long time ago I had some trouble getting it to work but I think it was something simple I just cant think of what I did.

Thanks!

Display port isnt showing up. I thought the first time a built this I went to the AMD control center or something but I cant find anything that seems to be working
 
Check if the display port cable is securely plugged in.
Do you have another displayport cable to test?
Test the monitor(the one using displayport now) with DVI or HDMi if possible. Test another monitor with the displayport cable.

Try to find if the monitor's or the gpu's displayport is broken. If not check the displayport cable.

Checked. The cables work as well as the monitors. I feel like i remember doing something to enable this 3rd monitor before. Any ideas where that would be?
