Autofocus and Manual Focus Problems 🔥🔥🔥🔥

Autofocus and Manual Focus Guide:

1. After starting up, the projector will automatically start the auto focus mode.
2. If necessary, after adjusting the size and distance of the projector, you could press the "F- " and "F+" buttons of the remote control to manually adjust the focus until a clear image is obtained.

Troubleshooting Guide for Ensuring Image Clarity

1. Observe Image Clarity:

   • Carefully examine the projected image, focusing on text and detailed sections.
   • If text appears blurry, edges are unclear, or details are missing, it may indicate a focus issue.

2. Compare Clarity in Different Areas:

   • Check the clarity of the image in both the central and edge areas.
   • Manual focus adjustment is needed to achieve the best clarity if the center is clear but the edges are blurry, or vice versa.

3. Adjust Focus Button:

   • Slowly adjust the manual focus ring or button until the image becomes clear.
   • Make sure the middle of the focus is clear, a little blurred edge is a normal phenomenon, and you can take pictures to confirm with us if it affects you watching a video/picture.

4. Check Lens Surface:

   • Ensure the lens surface is clean and free from dust or dirt. Use a specialized lens cleaning cloth to gently wipe the lens if it is dirty.

5. Adjust Projection Distance:

   • Check whether the focus has been adjusted to the best position, Please move the projector forward or backward proportionally in case the adjustment is unable to obtain a satisfactory definition.
   • If the distance is too far or too close, it can result in a blurry image.

6. Check Resolution Settings:

   • Confirm that the projector's resolution setting matches the input signal's resolution.
   • Mismatched resolutions can affect image clarity.

7. Use Keystone Correction Feature:

   • If the image has keystone distortion (where the top and bottom widths of the image are not consistent), use the projector's keystone correction feature to adjust it.(Poseidon-E40-Keystone-Correction)
   • Adjust the angle to support up to 30°, with a recommended optimal angle of 20° for clearer images.

8. Check Projection Surface:

   • Ensure that the wall or screen you are projecting onto is flat and smooth.

   • Uneven surfaces can distort the image and cause areas to appear out of focus.
     If the projection surface is not flat, consider using a projection screen or a smoother wall area.
