6.3 Screen Mirroring & Content Protection

Please note the following important information regarding screen mirroring:

• HDCP Limitations: Due to content protection agreements (HDCP), screen mirroring will not display video or audio for certain streaming applications such as Amazon Prime Video, Netflix, Hulu, Disney+, etc. This is a standard industry limitation, not a defect of the projector.
• Solution for Streaming Apps: To watch content from these protected apps, connect a streaming device (e.g., Fire TV Stick, Roku, Chromecast) directly to the projector via the HDMI port. Alternatively, connect your laptop or computer via HDMI.
• Connecting iPhone/iPad: For iPhone/iPad users, connect using a USB-to-Lightning or USB-to-Type-C cable (original cable recommended for stable connection). Different iPhone models may require different cables.

• Connecting Android Phones/Tablets: Check if your Android device supports video-out function (MHL). If yes, use a Micro USB/Type-C to HDMI adapter (not included). If not, use a streaming stick (like Roku/Fire Stick) for display.

7. Image Adjustment

7.1 Auto Keystone Correction

The Tecaki projector features advanced auto keystone correction. This function automatically adjusts the image to be rectangular, even if the projector is placed at an angle. This correction primarily applies to vertical distortion.

7.2 Manual Focus

To achieve the sharpest image, rotate the focus ring on the projector lens until the projected image is clear and crisp.

7.3 Zoom Function

You can adjust the image size from 75% to 100% without physically moving the projector. Access the zoom function through the projector's on-screen menu settings.

8. Maintenance

Proper maintenance ensures the longevity and optimal performance of your projector:

• Lens Cleaning: Use the provided cleaning kit or a soft, lint-free cloth specifically designed for optical lenses to gently wipe the projector lens. Avoid using abrasive materials or harsh chemicals.
• Ventilation: Ensure the projector's ventilation vents are clear and unobstructed to allow for proper airflow. The built-in cooling system relies on clear vents to prevent overheating.
• Storage: When not in use for extended periods, store the projector in a cool, dry place, away from direct sunlight and excessive dust.
• Power Off Properly: Always power off the projector using the designated power button and allow it to complete its shutdown cycle before unplugging.

9. Troubleshooting

This section addresses common issues you might encounter:

• No Picture/Signal:
  • Ensure the correct input source is selected on the projector.
  • Check all cable connections (HDMI, USB) are secure and properly inserted.
  • If using screen mirroring for streaming apps (Netflix, Hulu, Prime Video), remember these are often blocked by HDCP. Use a streaming stick or connect a laptop via HDMI instead.
• No Audio:
  • Check the volume level on both the projector and the connected source device.
  • If playing videos with Dolby Sound, the projector may not support it. Turn off Dolby Sound on the connected device or app.
  • Ensure Bluetooth audio devices are properly paired and connected.
  • If using HDMI, ensure the audio output is correctly configured on your source device.
• Image is Blurry:
  • Adjust the manual focus ring on the projector lens.
  • Ensure the projection distance is within the recommended range for optimal clarity (80-120 inches for best viewing experience).
• Image is Distorted/Trapezoidal:
  • The projector has auto keystone correction. Ensure the projector is placed on a stable, level surface.
  • If the distortion persists, try repositioning the projector directly in front of the screen/wall.
• Projector Overheating/Shuts Down:
  • Ensure the ventilation vents are not blocked.
  • Operate the projector in a well-ventilated area.
  • Allow the projector to cool down if it has been running for an extended period.
