Overhead Projector Tip- best results!!

For best results, slant the screen forward slightly so it meets at a 90 degree angle with the projected image light beam. In not, then a keystone effect results where the projected image is taller on top or on the sides; in other words, the projected image is a parallelogram, not a square.

How do I adjust view from an angle?


Best to have the projector 90 degrees up and down and left to right to the screen. Try turning the projector to move the image left or right.

keystone not working


Manual: http://www.mitsubishi-presentations.com/wp-content/files_mf/mitsubishi_manual_xd250ust.pdf

Installation>Wall Screen>Keystone

The automatic keystone adjustment may not be carried out correctly

because of the ambient temperature and the installation

conditions of the projector and the screen. In such cases, correct

the keystone manually.

• When the projector is projecting images where acceleration is

present, such as in a vehicle and aircraft, the automatic keystone

adjustment may not function correctly. In such a case, set AUTO

KEYSTONE in the INSTALLATION menu to OFF and correct the

keystone manually.

• You can correct the vertical keystones. However, their adjustment
ranges are limited in such correction.

When the keystone adjustment is carried out, the adjustment

value is indicated. Note that this value doesn't mean a projection

angle.

• The allowable range of the adjustment value in the keystone

adjustment varies depending on the installation conditions.

• When the keystone adjustment takes effect, the resolution

decreases. In addition, stripes may appear or straight lines may

bend in images with complicated patterns. They are not due to

product malfunctions.

• Noise may appear on the screen during the keystone adjustment

because of the type of the video signal being projected and the

setting values of the keystone adjustment. In such cases, set the

keystone adjustment values in the range where the image is displayed

without noise.

• When the keystone adjustment is carried out, the image may not
be displayed correctly because of the type of input signal.

bottom of screen is projecting at an angle. Other 3 sides are at 90 degree angles


It is called as keystone distortion. To correct the problem press the "Keystone" button on the projector, then press left, right, down & up arrow buttons to adjust the angle at 90 degrees.

My picture slants in towards the top from bottom


The issue has to do with something called "Keystone". This allows you to set the projector at an angle and project on an angle. When you set the projector on a flat surface, you would need to adjust the keystone to get rid of the "trapazoid" look of the image.

Slanted Border- Projector image is not square


Is the image slanted on the bottom as well?
Make sure the projector's throw is pointed directly at the target ie. screen or wall etc. there's not much else it could be.
