I have my PJ ceiling mounted. The base of the PJ is level as per a sprit level. What angle is the then projecting at?
My screen size is 106" 16:9 screen
What settings do I need to use for the Focus Rings?

I got a good setup. Pretty good corner focus, or good enough I can read the text on the windows desktop in 1080

Are you asking about the H V Scheimpflug adjustment) rings? There's often a chart on the inside of the cabinet piece that mount around the lenses. It lists settings that apply based on screen width. If you don't find the chart there, it's also listed in the setup manual.

Thx, but the chart is for 4:3 screens. So I guess the real question is how do these change for 16:9 setups. Also the projection angle is unclear.
When the projector is mounted on the ceiling is is perfectly level on the base, what is the angle?

If I remember right, those charts are based on width. Assuming I'm right (and it's been years since I've owned an XG so I'm not sure) you should look at your 16:9 width, figure the diagonal of a 4:3 screen with that width, and use that size to look up the settings on the chart.

Thx Gary,
After I checked the set up the projector I had done, and ran the math they both matched the 120" setting. The little holes were already lined up.
So a 106" screen using as much phosphor as possible is equivalent to 120" 4:3 when running 1080i@96hz for future reference.
