just got this projector second hand from a friend, set it on a wood piece which is mounted about 4~ feet from the ground.
i noticed that if its not centered the screen curves, is there no way to fix the curve? does the projector have to be EXACTLY level with where i want to watch.
if you dont know what i mean about curve, im at work so i painted it so you see the main idea.
the projector is faced down so that the screen will be lower, its way to high if i have it level. is leveling it the only way to get a normal screen.

You might try the projector's keystone adjustments. They're in the Installation menu.

The projector needs to be horizontal to avoid keystone distortion and for best resolution. It has some minimal keystone adjustments but no lens shift. Keystone adjustment is an electronic adjustment, and using it sacrifices some horizontal resolution. To prevent keystone distortion, the lens needs to be at the same level as the bottom of the screen if the projector is "upright" on a table, or level with the top of the screen if the projector is mounted "upside down", hanging from the ceiling.
