Assalamu Alaikum, hello there!
I'm not that much of a tech nerd, however, I could suggest a few things.
Update the drivers, or make sure they're installed correctly.
Try a clean reinstall of Zorin OS if possible; reinstallation helps sometimes with issues.
Could it be that not all of Your DisplayPort Plugs support the same Resolutions and Refresh Rates? Maybe only the one next to the HDMI have fully Support. You should check that.

Well I'm back in business. My solution was to buy a new graphics card, Amd Radeon rx 9070 xt. First Zorin didn't recognize the card but I got to work with this: Help installing AMD graphics drivers for my amd RX 9060 XT 8gb GPU - #38 by Aravisian
Now everything seem to work. So the previous card was to blame for the black screen.
