Epson PowerLite Pro Z9870UNL User's Guide

To connect your Epson PowerLite Pro Z9870UNL to a computer, use a VGA or HDMI cable. Plug one end into the projector's input port and the other into the computer's output port. Select the correct input source using the projector's remote or control panel.
Ensure the power cable is securely connected to both the projector and a working electrical outlet. Check the power indicator light; if it's off, try a different outlet. If the light is on but the projector doesn't start, it might be in standby mode. Press the power button on the remote or control panel to turn it on.
Adjust the image size by moving the projector closer to or farther from the screen. You can also use the zoom ring on the projector lens. For precise adjustments, access the projector's menu settings and navigate to the 'Image' section to fine-tune size and positioning.
Check that the audio cables are connected securely. Ensure the volume is turned up on both the projector and the source device. Verify that the correct audio input is selected in the projector's settings. If using HDMI, make sure the audio output on your device is set to HDMI.

Check the projector's keystone settings and adjust them using the remote or control panel. Ensure the projector is positioned perpendicular to the screen. For advanced corrections, use the 'Geometry Correction' feature in the projector menu.
