If you are projecting from a computer, press the Auto button on the remote control to automatically
adjust the tracking and sync. If the problem remains, display a uniformly patterned image on the
screen and manually adjust the Tracking and Sync settings.
If you adjusted the image shape using the projector controls, try decreasing the Sharpness setting to
improve image quality.
If you connected an extension power cable, try projecting without it to see if it caused interference in
the signal.
If you are using the USB Display function, turn off the Transfer layered window setting in the Epson
USB Display Settings program on your computer.

Solutions When the Image is Fuzzy or Blurry
If the projected image is fuzzy or blurry, try the following solutions:
Adjust the image focus.
Clean the projector lens.
Note: To avoid condensation on the lens after bringing the projector in from a cold environment, let the
projector warm up to room temperature before using it.
Position the projector close enough to the screen.
Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
Turn on automatic keystone adjustment in the projector's menus.
Adjust the Sharpness setting to improve image quality.
If you are projecting from a computer, press the Auto button on the remote control to automatically
adjust the tracking and sync. If any bands or overall blurriness remain, display a uniformly patterned
image on the screen and manually adjust the Tracking and Sync settings.
If you are projecting from a computer, try using a lower resolution or try to match the projector's native
resolution.
