Fixing Problems If the image is out of focus: ❏ Be sure the lens cover is open. ❏ While displaying the on-screen menu, adjust the focus ring. (The image size should not change; if it does, you are adjusting the zoom not the focus.) ❏ Ensure the projection screen is 1.2 to 12 m (4 to 40 ft) from the projector. ❏ For a computer connection, set the display resolution on the computer to 1024 x 768 pixels. If the computer has multiple monitors, adjust the resolution of the monitor assigned to the projector. ❏ Check the projection lens to see if it needs cleaning. If an upside-down or reversed image is displayed: ❏ The projector has been set to the wrong position setting. Open the on-screen menu, select Setup > Projector position, and select the correct setting. If the image is too small or too large: ❏ Adjust the zoom ring on top of the projector. ❏ Be sure the projector is 1.2 to 12 m (4 to 40 ft) from the projection screen. ❏ Open the on-screen menu and select Adjust picture > Adjust picture mode > Aspect ratio. Try the different settings. ❏ For a wide-screen picture, open the on-screen menu and select Adjust picture > Shape settings and try setting Widescreen input to Yes. If the image has slanted sides: ❏ As much as possible, reposition the projector so that it is centered on the screen and below the bottom or above the top of the screen. ❏ Open the on-screen menu and select Quick choice > Keystone. Adjust the setting as needed. 58 User's Guide
