Guides

Setting up the projector

Instructions from the manual
Place and install the projector10 steps
  1. Use a sturdy, level surface or compatible mount, parallel and square to the screen.
  2. Keep vents unobstructed and stay within reach of a grounded outlet.
  3. If centering is impossible, use lens shift rather than keystone for better image quality.
  4. Front, rear, front-ceiling and rear-ceiling arrangements are documented.
  5. Select the matching Projection setting for rear or ceiling installation.
  6. Leave the source-diagram clearances: 10 cm (3.94 inches), 20 cm (7.87 inches) and 30 cm (11.81 inches) at their illustrated sides; use the complete placement figure rather than inferring sides.
  7. Ceiling or wall installation requires specialist knowledge; have the dealer carry it out.
  8. Secure every fixing point of the supported Epson mount and use a safety wire strong enough for the projector.
  9. Do not use screw-locking adhesive, oil or lubricant.
  10. Do not install vertically, operate on the side, or tilt more than 10 degrees forward or back.
Top-view installation-space drawing with complete dimension arrows and repeated 1 labels
Installation space — keep the marked clearances and vents unobstructed

Diagram key

  • 1: Leave 3.94 inches (10 cm) at both positions marked 1.
  • 2: Leave 7.87 inches (20 cm) at position 2.
  • 3: Leave 11.81 inches (30 cm) at position 3.
  • Wavy lines: Keep the illustrated air exhaust and intake vent areas unobstructed.
Use the projection distance table6 steps
  1. Distance, zoom, aspect ratio and other settings determine approximate image size.
  2. Use the manual’s 16:9 table and Epson projection calculator; the manual explicitly notes that converted figures may be rounded.
  3. The table covers 40, 60, 80, 100, 120, 150, 200, 300, 400 and 500-inch images.
  4. For example, its native 100-inch row gives a wide-to-tele distance of 115.7–187.8 inches (294–477 cm).
  5. Use the illustrated lens center and offset definitions when positioning the image.
  6. For screens larger than 300 inches, a high-gain screen and a light-controlled environment may be necessary.
Install the safety wire3 steps
  1. For a ceiling or shelf installation, pass the optional safety wire through the projector security-cable attachment point.
  2. Fix its other end to a structure strong enough to carry the projector.
  3. Loop an overly long wire to minimize slack.
Install or replace remote batteries12 steps
  1. Use two AAA alkaline or manganese batteries.
  2. Do not mix types or combine old and new batteries.
  3. Remove the battery cover and, when replacing, remove the old cells.
  4. If battery fluid has leaked, wipe it away with a soft cloth without getting it on your hands.
  5. Wash your hands immediately if contact occurs.
  6. Fit the batteries with the indicated plus and minus polarity.
  7. Incorrect polarity can cause leakage or explosion, fire, injury or product damage.
  8. Refit the cover until it clicks.
  9. Dispose of cells under local rules.
  10. Keep them away from heat, flame and children: they are choking and swallowing hazards.
  11. Seek immediate medical attention if one is swallowed.
  12. Remove cells for long-term storage.
Connect an HDMI video source11 steps
  1. Connect projector and source before connecting the projector power cord.
  2. Do not turn on the video source before connecting it; this can damage the projector.
  3. Match connector shape and orientation without forcing a plug.
  4. Connect an optional HDMI cable from the source HDMI output to the projector HDMI port.
  5. For 4K Enhancement at 60 Hz, the guide specifies an HDMI 2.1 ultra-high-speed rated cable.
  6. If incompatible-cable images are incorrect, try changing Signal > EDID.
  7. The internal speaker receives mono analog audio converted from HDMI; external speakers can receive stereo.
  8. If sound is wrong, check Settings > Audio Out Device.
  9. For gaming lag, set the console to a progressive 480p, 720p or higher output according to its instructions; Fast Image Processing can reduce lag.
  10. A game-console source change can take a few seconds.
  11. HDMI CEC-compliant sources can be controlled by enabling HDMI Link; both cable and device must support it.
Connect a computer for HDMI video and audio6 steps
  1. Connect an optional HDMI cable from the computer HDMI output to the projector HDMI port.
  2. For a Mac without a compatible output, ask Apple about an adapter; ask the device manufacturer about smartphone or tablet adapters.
  3. HDMI audio is converted to mono for the internal speaker or stereo for external speakers.
  4. Select EPSON PJ as the computer HDMI audio playback device.
  5. If audio is missing, check Settings > Audio Out Device.
  6. Older Macs may not support HDMI audio.
Connect external speakers or headphones7 steps
  1. Connect the computer or video source to the projector with the required audio/video connections.
  2. Obtain an appropriate stereo mini-jack cable or adapter for the speakers or headphones.
  3. Connect the speaker end, then plug the stereo mini-jack into Audio Out.
  4. A self-powered speaker system or an amplifier with speakers can be used; connecting external speakers disables the internal speaker.
  5. Set HDMI Link to On and Audio Out Device to AV System as directed in the connection section.
  6. Without an attached A/V system, external Audio Out speakers still receive audio with AV System selected.
  7. Lower volume before playback or shutdown and increase it gradually after startup to protect hearing.
Connect HDMI ARC speakers or a receiver3 steps
  1. Use ARC-compatible external speakers or an A/V receiver and an optional HDMI cable.
  2. Enable Settings > HDMI Link and select AV System for Audio Out Device.
  3. Connect the cable to the external system’s ARC-compatible HDMI port and the projector HDMI1 (ARC) port.
Connect another streaming media player5 steps
  1. The built-in streaming device can be replaced with another player.
  2. Remove the rear cover and connect the alternative player to HDMI2.
  3. If needed, connect the player power cable to the projector USB-A port and its other end to the player.
  4. Extended > USB Power > Always On keeps it powered while the projector is not projecting.
  5. Fit the alternate rear cover.
Set up Android TV10 steps
  1. At first use, turn on the projector.
  2. When prompted, hold Enter and Home together on the projector remote until pairing completes; its light flashes while pairing.
  3. Use the arrows and Enter to select a language.
  4. Choose Continue to use an Android phone for Wi-Fi and Google-account setup, follow the prompts and then continue the final setup.
  5. Or choose Skip for manual setup.
  6. For manual setup, select the wireless network and follow its prompts.
  7. Choose Sign In at the Google-account screen and follow the prompts, or Skip to proceed without an account.
  8. Finish the on-screen settings to reach the Home screen.
