Definitely got the right settings in regards to mount type in the settings.
Basically this is what I did:
1. Lens Centre on the projector menu
2. Used Lens shift to move the image as far down as possible
This gives me max lens shift which only brings the top of the image inline with corner of ceiling/wall.
Trying to fit a 120" screen which is possible. Looked at the JVC calculator, maybe just not possible without a extension.
Not sure if this is normal or not.
I moved my projector up and down to work out what size extension pole do i need.
To achieve the following parameters:
Ceiling Height: 2.7m
Image Height from Ground: 85cm
Image Size (Diagonal): 120"
Aspect Ratio: 16:9
Lens to Screen Distance (Throw Distance): 3.63m
I had to adjust the projector height to 24" from ceiling to achieve the above parameters, this was with Lens Shift set to Max.
Does this sound about right?
