Support Projectors EB Series Epson BrightLink EB-725Wi

The pen position is not accurate. What should I do?

  • If the pen position is not the same as the mouse pointer, try the following solutions:

    • Reset the keystone, Quick Corner, and Arc Correction settings to their factory defaults.
    • If you mounted the projector using a wall mount and used keystone or other digital correction settings to adjust the image, return the settings to their factory defaults. Use the adjustment dials on the wall mount to square off the image shape; do not use any digital correction. Then focus the image and recalibrate.

      Note: You can use the installation guide in the Settings menu to help you square off the image shape.

    • If you use the E-Zoom + button on the remote control to enlarge the image, the pen position is not accurate. When you return the image to the original size, the position should be correct.
    • Select Reset All on the Initial/All Settings menu to restore the projector settings to their default values.
    • Set the computer's output resolution to match the projector's native resolution:
      • BrightLink EB-725Wi: 1280 × 800 pixels (WXGA)
      • BrightLink EB-735Fi: 1920 × 1080 pixels (1080p)
    • If you connect your projector through a video scaler, make sure the video scaler output resolution setting matches your projector's native resolution.
    • If you used the mount's adjustment tools to adjust the image shape and the image is not an even rectangle, use the adjustment dials on the mount again to correct the image shape.
    • Focus the image to sharpen it.
    • Make sure you calibrated the system. Try manual calibration.
    • Make sure the cable cover is in place to keep cables from blocking the signal.
    • Adjust the pen operation area.
    • In PC Interactive mode, turn off the Auto Adjust Pen Area setting and select the Manual Adj. Pen Area setting (USB cable required).
    • If you are using a Windows computer with the projector, make sure the Scaling setting in the Intel HD Graphics Control Panel is set to Maintain Display Scaling.
