Solutions When The Interactive Pen Position Is Not Accurate; Solutions When The Interactive Pens Are Slow Or Difficult To Use - Epson EB-770Fi User Manual

• If you are using multiple interactive projectors in the same room, make sure you are using a sync
cable between the projectors and that the Installation of Projectors > Sync of Projectors setting in
the Pen/Touch menu is set to Wired. If you do not have a sync cable, set the Infrared Intensity
setting to Strong in the Pen/Touch menu. Use a 3.5 mm stereo mini-jack audio cable and make sure it
is labeled "No resistance."

Solutions When the Interactive Pen Position Is Not Accurate

If the pen position is not the same as the mouse pointer, try the following solutions:
• Make sure you have calibrated the system. Try manual calibration if auto calibration fails.
• 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. Instead, use the adjustment dials on
the wall mount to adjust the image shape; do not use any digital correction. Then focus the image and
recalibrate.
• 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 from the menu to restore the projector settings to their default values.
• Set the output resolution of your computer to match the native resolution of the projector. If you
connected your projector through a video scaler, make sure the video scaler output resolution setting
matches your projector's native resolution.
• Focus the image to sharpen it.
• Try adjusting the pen operation area.
• In PC Interactivity (in the Pen/Touch menu), turn off the Auto Adjust Pen Area setting and select the
Manual Adj. Pen Area setting.

Solutions When the Interactive Pens Are Slow or Difficult to Use

If the pens are difficult to use or respond too slowly, try the following solutions:
• For easier operation, hold the pen perpendicular to the projection surface.
• For the best performance, connect your computer to the projector using a VGA or HDMI cable for
display and the USB cable for interactivity.
• If you are using USB Display in Windows, you may need to disable Windows Aero in the Epson USB
Display Settings program on your computer.
