Your GTX 1080ti is not supported by macOS since High Sierra.

However you might, just might, get display output but in VESA mode, without acceleration. Not guaranteed though.

Changing your GPU is the only way forward - unless you go with High Sierra and the NVidia web-drivers.

Any reason why you are using a very old version of OpenCore?

Normally we would suggest adding the "-v" boot-argument so that your PC starts in "Verbose" mode. That will give you a scrolling screen of text during boot and stop. Grab a photo and upload it. However with the GTX 1080 I doubt this will help.

You may not be able to run a version of MacOS older than High Sierra / Sierra 10.12.6 on your system due to your graphics card, and newer versions won't work properly with your graphics card.

As already mentioned, you should really consider replacing your graphics card with a supported AMD graphics card if you really want to install and run MacOS on your system.
