A projector is responsible for taking a video signal and projecting it onto a screen or wall, creating a large-format display. Modern projectors primarily utilize HDMI connections for transmitting high-definition video and audio signals. You’ll find various input ports on your projector, but for this guide, we’ll focus on the HDMI input(s). Understanding the resolution capabilities (e.g., 1080p, 4K) and refresh rate of your projector is important for optimizing your setup.
The AVR: The Heart of Your Audio System
An Audio/Video Receiver (AVR) is the central hub of your home theater. It receives audio and video signals from various sources, processes them, amplifies the audio, and then sends the appropriate signals to your speakers and display device. Your AVR is equipped with multiple input and output ports, the most critical for this discussion being HDMI inputs for your sources and an HDMI output (often labeled “HDMI Out” or “HDMI Monitor Out”) that connects to your projector. The AVR also handles audio decoding (Dolby Atmos, DTS:X, etc.) and speaker management, ensuring a rich and enveloping sound experience.
The Essential Connections: HDMI is Key
The most common and recommended method for connecting a projector to an AVR is through HDMI (High-Definition Multimedia Interface) cables. HDMI is a digital standard that transmits both uncompressed audio and video signals over a single cable, simplifying your setup and ensuring the highest possible quality.
Why HDMI? The Advantages
HDMI offers several significant advantages for home theater setups:

Before you begin connecting any cables, it’s crucial to power off all your equipment (projector, AVR, and source devices). This prevents potential electrical surges or damage to the devices.
Step 2: Connect Source Devices to Your AVR
This is where your AVR shines as the central hub.
- Take an HDMI cable and connect one end to the HDMI output of your first source device (e.g., Blu-ray player).
- Connect the other end of this HDMI cable to an available HDMI input on your AVR. Your AVR will have several HDMI inputs, often labeled with names like “Blu-ray,” “Game,” “AV 1,” “HDMI 1,” etc. Choose an input that makes sense for the device you’re connecting.
- Repeat this process for all your source devices, connecting each one to a different HDMI input on your AVR.
Step 3: Connect Your AVR to Your Projector
This is the key step for sending the processed video and audio to your display.
- Locate the HDMI output port on your AVR. This is usually labeled “HDMI Out,” “HDMI Monitor Out,” or “HDMI ARC/eARC.”
- Take another HDMI cable and connect one end to this HDMI output port on your AVR.
- Connect the other end of this HDMI cable to an available HDMI input port on your projector.
Step 4: Connect Your Speakers to Your AVR
While not directly part of the projector connection, this is essential for the audio experience. Your AVR will have speaker terminals on the back. Connect your front left, front right, center, surround, and any height speakers according to your AVR’s manual and your desired speaker configuration (e.g., 5.1, 7.1, Dolby Atmos). Ensure you match the positive (+) and negative (-) terminals correctly.
Step 5: Power On Your Devices (in the Correct Order)
Once all connections are made, it’s time to power things up. The recommended order is generally:
- Turn on your AVR first.
- Turn on your projector.
- Turn on your source devices.
This order helps ensure that the devices handshake correctly, allowing the AVR to recognize the connected display.
Step 6: Select the Correct Input on Your Projector
On your projector’s remote control or via its on-screen menu, you’ll need to select the HDMI input that you connected your AVR to. If you connected your AVR to HDMI 1 on your projector, select HDMI 1.

What is an AVR and why is it important for connecting a projector?
An AVR, or Audio/Video Receiver, is the central hub of your home theater system. It’s responsible for receiving audio and video signals from various sources like Blu-ray players, streaming devices, and game consoles, processing them, and then routing them to the appropriate output devices – in this case, your projector for video and your speakers for audio.
The AVR’s importance in connecting a projector lies in its ability to handle multiple inputs, upscale video signals, manage complex audio formats (like Dolby Atmos or DTS:X), and switch between different sources seamlessly. Without an AVR, you’d have to directly connect each source to your projector, which would severely limit your audio options and create a mess of cables.
What are the most common connection methods for linking a projector to an AVR?
The primary and most recommended connection method is using an HDMI cable. HDMI carries both high-definition video and multi-channel audio signals over a single cable, simplifying the setup and ensuring the best possible signal quality. You’ll typically connect an HDMI output from your AVR to an HDMI input on your projector.
For older projectors or AVRs that may lack sufficient HDMI ports, you might encounter component or composite video connections. However, these are significantly inferior in terms of picture quality and do not carry audio, requiring separate audio cables. It is always advisable to use HDMI whenever possible for a true cinematic experience.
How do I ensure the audio from my sources plays through my home theater speakers, not the projector’s built-in speakers?
To ensure audio plays through your home theater speakers, you need to correctly configure the audio output on your AVR. When you connect your sources (e.g., Blu-ray player, streaming device) to the AVR via HDMI, the AVR will automatically detect and process the audio. You then select the appropriate speaker output settings within the AVR’s menu to direct that audio to your connected sound system.
The key is to route all your audio sources through the AVR. Your projector should primarily receive the video signal. By ensuring your AVR is set as the audio destination for all your connected devices, and that the AVR’s audio outputs are connected to your speakers, you’ll bypass the projector’s internal speakers entirely, delivering rich, immersive sound.
What are the essential cables and accessories needed for a successful projector-to-AVR connection?
The most crucial cable is a high-quality HDMI cable, preferably one that supports the latest HDMI standards (like HDMI 2.0 or 2.1) to ensure compatibility with high resolutions, refresh rates, and HDR content. You’ll also need speaker wire to connect your AVR to your surround sound speaker system.
Other useful accessories might include an HDMI splitter if your AVR has limited outputs or if you wish to send the signal to both a projector and a TV simultaneously, and potentially an audio extractor if you need to separate audio from a signal for specific audio processors. Surge protectors are also recommended to safeguard your valuable AV equipment.
How do I configure my AVR’s settings to send the correct video signal to my projector?
Within your AVR’s setup menu, you’ll need to identify the HDMI output port that is physically connected to your projector. Assign this port as the primary video output for your system. Most AVRs offer an on-screen display (OSD) that guides you through these settings, allowing you to select the correct output for your chosen input source.
You should also ensure that the video resolution and aspect ratio settings on the AVR are compatible with your projector’s native resolution and capabilities. Many AVRs have auto-detection features, but manually adjusting these settings, such as enabling 4K passthrough or setting the correct color space, can optimize the picture quality and prevent compatibility issues.
What troubleshooting steps should I take if I’m not getting a picture or sound from my projector?
Start with the most basic checks: ensure all cables are securely plugged into the correct ports on both the AVR and the projector. Verify that both the AVR and the projector are powered on and set to the correct input source. If using HDMI, try a different HDMI cable or port to rule out faulty hardware.
If you still have no picture or sound, reboot your AVR and all connected sources. Check the AVR’s menu for any audio or video output settings that might be incorrectly configured, such as muted outputs or incorrect resolution settings. Consulting the user manuals for both your AVR and projector will provide specific troubleshooting guidance for your models.
Can I connect multiple devices to my AVR and output to both a projector and a TV simultaneously?
Yes, many modern AVRs are equipped with multiple HDMI outputs, allowing you to connect and send the same video and audio signal to two different displays, such as a projector and a television, at the same time. This is incredibly useful for switching between a large-screen cinematic experience and a more casual viewing option.
When setting this up, you’ll typically connect one HDMI output to your projector and another to your TV. Within the AVR’s settings, you’ll need to configure which output is active for each input source, or if you want them to mirror each other. Be mindful of potential resolution differences; the AVR will usually output the lowest common resolution supported by both displays.
