Try pressing and holding CTRL while booting until Ambient appears and you should get a 1024x768 resolution.
If this works, you should be able to try to find and save a screen mode that works then.
Please note that no Mac Mini G4 will be able to drive a full 3840x1200 resolution. This is not exactly the right monitor for this type of machine.
