How to Connect a Gaming Projector Soundbar – Three Simple Options
Option 1: HDMI ARC/eARC (Recommended)
Use a projector with HDMI ARC support (for example, the Optoma HD146X).
Connect the projector’s ARC port directly to the soundbar’s HDMI ARC input.
Enable CEC (Consumer Electronics Control) in both devices’ settings for seamless volume and power control.
Option 2: Optical Audio (If ARC Is Missing)
Connect your console or streaming device to the projector via HDMI for video.
Route the audio output separately from the device to the soundbar using an optical cable.
This setup provides solid audio quality, even without ARC support.
Option 3: HDMI Splitter with ARC
Ideal for projectors that lack HDMI ARC or optical ports.
Use an HDMI splitter with ARC extraction to send video to the projector and audio to the soundbar simultaneously.
This solution ensures full compatibility with any gaming projector soundbar setup.
Key Features to Look for in a Gaming Projector Soundbar:

Sound Placement Tips for a Gaming Projector Soundbar Setup:
Mount the Soundbar: Install or position your soundbar directly below or in front of the projector screen for accurate sound alignment with on-screen action.
Center the Subwoofer: Place the subwoofer near the middle of the room or slightly offset to achieve even, balanced bass throughout your space.
Keep Speaker Areas Clear: Avoid blocking your soundbar or subwoofer with furniture, as obstructions can distort or muffle the sound.
Use Soundproof Foam: If you’re in an apartment, adding soundproof foam panels can help reduce noise transfer and improve overall acoustics in your gaming projector soundbar setup.
