HP mp3135w manual If the image is out of focus, If an upside-down or reversed image is displayed

Fixing Problems

If the image is out of focus:

❏Be sure the lens cap is removed.

❏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.

❏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 > Aspect ratio. Set to Best Fit or Fill. For a wide-screen picture, try setting the aspect ratio to 16:9.

If the image has slanted edges:

❏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.

❏The projector can automatically correct slanted sides of the picture when the projector is tilted up or down. However, additional corrections might be required in certain situations. Open the on-screen menu and select Adjust picture > Keystone correction. Adjust the horizontal and vertical settings as needed or enable or disable the auto keystone correction.
