It looks like you're trying to get X to start up with a resolution of
1920x1080. According to this chart that you've quoted, your projector
can't display at that resolution. Try creating a modeline for the
1024x768 or 1280x1024 resolutions and see if they will work. I doubt
my 1024x768 modelines will help, but here they are:
ModeLine "1024x768" 118.1 1024 1096 1208 1392 768 769 772 816
ModeLine "1024x768" 116.8 1024 1096 1208 1392 768 769 772 815
ModeLine "1024x768" 115.7 1024 1096 1208 1392 768 769 772 815
