That motherboard does not support i9-11900K:

You need to install a supported CPU so that your PC will POST. Then the DP should work provided that the CPU has integrated graphics.

I think that is a old list before the 11XXX processors were released.

Well spotted, so may be the OP just needs to update BIOS to latest ? If not that, I'm stumped.

I don't know why they only put a DP port on the board.

Are you using a video card? If so it will have the boards DP disabled sometimes you can turn it on in BIOS.

If no video card is used if you have one you can install try that to see if the board actually works.

Not the F or KF version of the processor right as they have no built in video.

From their BIOS update or check for bent pins in the boards socket.

What monitor are you using?
You are saying when you try to change the resolution all other options are grayed out.
Unplug the monitor from the wall for a few minutes and then try it again.

Right click on the desktop, select display settings, this should bring up you display can you change it their to 1080p or is it grayed out?

If its grayed out go to advanced display settings (right below the resolution) and make sure it is listing the monitor you have if it is then change the refresh rate to 59. whatever it list and try again.

EDIT I will post in a different section to try to get more help for you.

This is inelegant, but it works:

1. Make sure Monitor #1 has DisplayPort 1.2 set as Enable.
   Monitor #2 should be set as Disable.
2. Open Device Manager. Click Monitors. Click View and Show Hidden Devices.
   Uninstall the Digital Flat Panel (640x480 60Hz) device.
   Also uninstall any hidden (greyed out) devices.
3. Disconnect Monitor 1 from computer.
4. Reboot computer
5. Unplug monitors and wait a few seconds
6. Plug monitors back in to power
7. Connect Monitor 1 to computer.

I've had this problem for years and have searched all over for an elegant solution. To my knowledge, none exists.
