Help me adjusting my projector

I am mounting Optoma WU515ST to a ceiling and currently I am getting this shape. Please help me how do I adjust my projector so that the shape becomes square rectangle? Please see my attached image.

The white grid lines is the current showing. I like it to be like the red rectangle

Re: Help me adjusting my projector

You must place the projector in the CENTER (left to right) of the Red Rectangle to get the best images. It looks like your projector's lens is is too far to the right AND it looks like the projector is rotated a little bit. The left edge of the projection image and the right edge of the projection image should be the same distance from the projector lens.

DO NOT USE Keystone controls in your projector, they cause a loss of resolution and can also make the shape of the picture better (more square), but doing that causes resolution loss. If this was a new projector, the Keystone controls should be set to ZERO from the factory. If this is a used projector, the previous owner may have used a poor setup and left the keystone control set to a high number for left-right Keystone.

The projector ALSO appears to be rotated slightly. You should be able to fix that with adjustments to the ceiling mount. It would appear that the left side of the projector is closer to the ceiling than the right side of the projector (assuming the ceiling is flat).

So it appears you have 2 problems.
