I got a sharp dt-510 and it looks great but, the screen is not even. On the left side its 43", on the right 42". Can anyone tell me how to fix this problem?


Thanks to anyone that helps

the projector must be square and level with the screen... move the projector..

Some projectors have lens shift. Check your manual and see if you have it. Otherwise I agree your lens needs to be centered with the screen.

It's level but what you mean square to the screen? It doesn't have lens shift. I'm also just throwing it on the wall.

Ok if you're just throwing it up on the wall the lens is not perfectly perpendicular to the wall. So you have it pointing to the side that is larger. Just turn the projector a little bit to the side that is smaller until they are even.


Edit: I guess technically the lens should be parallel to the wall and the center of the shaft of light coming out of the projector should be perpendicular to the wall.


What is happening is that the light on your left side has to travel farther to get to the wall therefore it is larger. If you were to draw a triangle where one point is the projector and the line opposite that point is the wall that would be the right side of your image. Now extend the lines going from the projector to the wall and draw another wall... this is the left side of your image and your second wall is longer than your first wall.


This is the best way I could think to explain what is going on. I hope it helped.
