solutions:
• Check the cables connecting your computer or video source to the projector. They should be:

• Securely connected at both ends
• Not connected to an extension cable
• No longer than 10 feet (3 m) for VGA/computer cables or 24 feet (7.3 m) for HDMI cables
• Check the settings on the projector's Signal menu to make sure they match the video source. If
available for your video source, adjust the Progressive and Noise Reduction settings.
• Select a computer video resolution and refresh rate that are compatible with the projector.
• If you are projecting from a computer, press the Auto button on the remote control to automatically
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.
