If your projected image from the Casio XJ-F20XN appears skewed or distorted due to imperfect projector placement, you can easily correct this using the keystone correction feature. Here's how to adjust it: First, press the "Menu" button on either your remote control or the projector itself. Next, use the arrow keys to navigate to the "Installation" menu. Once there, select "Keystone" and confirm your selection by pressing the "Enter" button. You can now use the arrow keys to fine-tune the vertical keystone correction. The Casio XJ-F20XN offers a correction range of ±30°. When you're satisfied with the image, press the "Enter" button again to save your settings. For visual aids and more detailed information, consult the Casio XJ-F20XN user manual.
