Check

Are the image signals being output to the projector?

(Only when projecting images from a laptop computer or a computer with a built-in LCD screen)

Remedy

If the image signals are only being output to the computer's LCD monitor or to the accessory monitor, you need to change the output to an external destination as well as the computer's own monitor. For some computer models, when the image signals are output externally, they no longer appear on the LCD monitor or accessory monitor.

If the connection is made while the power of the projector or computer is already turned on, the Fn key (Function key) that changes the computer's image signal to external output may not work. Turn the power for the computer and the projector off and then back on again.

s "From Installation to Projection" p.26 s Computer's documentation

Images are fuzzy, out of focus, or distorted

Check

Is the distance between the projector and the screen over 2.5 m? (For EB-1775W)

Is Auto H/V-Keystoneset to Off? (EB-1775W only)

Is the focus adjusted correctly?

Is the projector at the correct distance?

Is the keystone adjustment value too large?

Has condensation formed on the lens?

Remedy

For the projected image to be automatically adjusted by Auto H/V-Keystone or Screen Fit, the projector cannot be more than approximately 1.0 to 2.5 m away from the screen. If the projector must be placed further away than this, manually adjust the projected image.

Setting it to On enables Auto H/V-Keystone.

s Settings - Keystone - Auto H/V-Keystone p.73

If you are using the projector with this setting off, manually adjust the projected image. s "Correcting manually - manual H/V-Keystone-"p.34

Adjust the focus using the [Focus] buttons (EB-1775W only) or Focus ring (EB-1770W/EB-1760W/EB-1750 only). s "Correcting the Focus" p.37

Is it projecting outside of the recommended projection distance range? Setup within the recommended range.

s "Screen Size and Projection Distance" p.118

Lower the projection angle to reduce the amount of keystone correction. s "Adjusting the Image Position" p.37

If the projector is suddenly taken from a cold environment to a warm environment, or if sudden ambient temperature changes occur, condensation may form on the surface of the lens, and this may cause the images to appear fuzzy. Set the projector up in the room about one hour before it is used. If condensation forms on the lens, turn the projector off and wait for the condensation to disappear.
