Connecting your laptop to an external monitor can transform your computing experience, offering a larger, more immersive display for work, entertainment, and gaming. However, a common point of confusion arises when users want to enjoy the audio from their laptop through their monitor’s built-in speakers or an attached sound system. This comprehensive guide will walk you through the various methods and troubleshooting steps to ensure you can seamlessly get audio from your laptop when it’s connected to your monitor, covering everything from simple cable choices to advanced audio settings.
Understanding the Connection: How Audio Travels
The journey of audio from your laptop to your monitor is primarily dictated by the type of connection you use. Modern monitors and laptops often support multiple connection standards, and not all of them carry audio signals.
The Crucial Role of HDMI
The High-Definition Multimedia Interface (HDMI) is arguably the most common and straightforward way to transmit both high-definition video and digital audio signals simultaneously from your laptop to your monitor. When you connect your laptop to a monitor using an HDMI cable, the audio data is packaged alongside the video data and sent directly to the monitor. This means if your monitor has built-in speakers or an audio output jack, you can potentially hear your laptop’s sound through it.
- Key takeaway: For seamless audio and video, HDMI is your best bet. Ensure both your laptop’s HDMI port and your monitor’s HDMI port support audio transmission. Most modern devices do.
DisplayPort: A Powerful Alternative
DisplayPort is another digital interface that, like HDMI, is capable of carrying both video and audio signals. It’s often found on higher-end monitors and graphics cards. In many cases, DisplayPort can offer higher bandwidth than HDMI, which can be beneficial for higher resolutions and refresh rates. When audio is transmitted over DisplayPort, it follows a similar path to HDMI, being sent directly to the monitor.
USB-C and Thunderbolt: The Versatile Connectors
USB-C, particularly when paired with Thunderbolt technology, has become incredibly versatile. Many modern laptops utilize USB-C ports for charging, data transfer, and even video output. If your USB-C port supports DisplayPort Alternate Mode (often indicated by a DisplayPort logo next to the port) or Thunderbolt 3/4, it can transmit audio to a compatible monitor. This is especially true for docking stations or monitors that have USB-C inputs that accept audio.
The Limitations of DVI and VGA
Older analog connections like DVI (Digital Visual Interface) and VGA (Video Graphics Array) are primarily designed for video transmission only. They do not carry audio signals. If you’re using a DVI or VGA cable to connect your laptop to your monitor, you will need a separate audio cable to get sound.
Setting Up Your Audio: A Step-by-Step Approach
Once you understand how audio travels, the setup process becomes much simpler. Here’s a breakdown of how to ensure your laptop’s audio is routed correctly to your monitor.
Step 1: Physical Connections
The first and most critical step is establishing the correct physical connection.
- For HDMI: Connect one end of the HDMI cable to your laptop’s HDMI output port and the other end to your monitor’s HDMI input port.
- For DisplayPort: Connect one end of the DisplayPort cable to your laptop’s DisplayPort output and the other end to your monitor’s DisplayPort input.
- For USB-C/Thunderbolt: Connect a compatible USB-C cable (ensure it supports video and audio, and if using Thunderbolt, ensure both devices support it) from your laptop’s USB-C port to the monitor’s USB-C input.
- For DVI/VGA (with separate audio): Connect your DVI or VGA cable for video. Then, locate your laptop’s audio output jack (usually a 3.5mm headphone jack) and connect it to your monitor’s audio input jack (if available) using a 3.5mm audio cable. Some monitors may have separate RCA audio inputs or other connectors, so consult your monitor’s manual.
Step 2: Selecting the Correct Audio Output Device on Your Laptop
After making the physical connection, your laptop needs to be instructed to send the audio signal through the chosen connection. This is done through your operating system’s audio settings.
Windows Audio Settings
- Right-click the speaker icon in the system tray (usually found in the bottom-right corner of your screen).
- Select Open Sound settings or Playback devices.
- In the Sound window or Sound settings page, you’ll see a list of available playback devices. Look for an entry that corresponds to your monitor. This might be named after your monitor’s brand and model, or it could simply be labeled “HDMI Output,” “DisplayPort,” or a similar generic name if the connection is being recognized.
- Select your monitor’s audio output as the default playback device. You can usually do this by right-clicking the device and choosing “Set as Default Device.”
- Test the audio by playing a video or music. You should now hear the sound through your monitor’s speakers or connected audio system.
macOS Audio Settings
- Click the Apple menu in the top-left corner of your screen.
- Select System Settings (or System Preferences on older macOS versions).
- Click on Sound in the sidebar.
- Go to the Output tab.
- You will see a list of available output devices. Select the option that corresponds to your monitor’s audio output. Similar to Windows, this might be labeled with your monitor’s name or a generic connection type like “HDMI,” “DisplayPort,” or “USB-C Audio.”
- Close the Sound settings. macOS usually applies changes immediately. Play some audio to confirm it’s coming through your monitor.
Step 3: Adjusting Monitor Volume and Settings
Even if the audio signal is successfully reaching your monitor, you might not hear anything if the volume is turned down or muted on the monitor itself.
- Use the monitor’s physical buttons: Most monitors have buttons on the front, side, or back to control volume, select inputs, and access the on-screen display (OSD) menu.
- Navigate the OSD menu: Look for a “Volume” or “Audio” section within the OSD menu. Ensure the volume is turned up and that the audio output isn’t muted.
- Check for specific audio modes: Some monitors have different audio modes (e.g., “Cinema,” “Game,” “Standard”). Experiment with these to see if it improves the sound quality.
Troubleshooting Common Issues
While the process is generally straightforward, you might encounter a few hiccups. Here are some common problems and their solutions:
No Sound at All
- Verify the Cable: Ensure your HDMI, DisplayPort, or USB-C cable is fully plugged into both the laptop and the monitor. Try a different cable if possible, as cables can be faulty.
- Confirm Audio Support: Double-check your laptop’s specifications and your monitor’s manual to confirm that the connection type you are using supports audio transmission.
- Default Playback Device: Revisit your operating system’s sound settings and ensure the correct audio output device (your monitor) is selected as the default.
- Monitor Volume and Mute: As mentioned earlier, check the volume level and ensure the monitor isn’t muted through its on-screen display.
- Laptop Volume:** Ensure your laptop’s volume is not muted or turned down.
Sound Only Through Laptop Speakers
This almost always points to an incorrect audio output selection on your laptop. Go back to your operating system’s sound settings and explicitly choose the monitor’s audio output as the default device.
Distorted or Choppy Audio
- Check Cable Quality: Lower-quality or damaged cables can sometimes lead to audio artifacts. Try a different, certified cable.
- Lower Audio Sample Rate: In some advanced audio settings on your laptop, you might be able to adjust the sample rate and bit depth. Sometimes, a lower setting can resolve issues. On Windows, this is typically found under the “Advanced” tab of the playback device properties.
- Update Audio Drivers: Outdated or corrupted audio drivers on your laptop can cause performance problems. Visit your laptop manufacturer’s website or the manufacturer of your sound card to download and install the latest drivers.
- Check for Interference: Other electronic devices can sometimes cause interference. Try moving your audio cables away from power supplies or other potential sources of electromagnetic interference.
Audio Works, But Video Doesn’t (or vice versa)
This usually indicates a problem with the cable or the ports themselves.
- Test Ports: Try connecting your laptop to a different display using the same cable, or connect your laptop to the monitor using a different cable. This helps isolate whether the issue is with the cable, the laptop port, or the monitor port.
- Update Graphics Drivers: Sometimes, integrated graphics drivers can affect the transmission of both video and audio over digital connections. Ensure your graphics drivers are up to date.
Advanced Considerations and Workarounds
In some cases, you might have a monitor that doesn’t have built-in speakers or an audio output, or perhaps you want to use a specific set of external speakers.
Using a Separate Audio Cable (for DVI/VGA or Monitors Without Audio Input)
If you are using DVI or VGA, or if your monitor lacks audio input capabilities but has an audio output jack, you will need a separate 3.5mm audio cable.
- Connect your video cable (DVI, VGA, or even HDMI/DisplayPort if the monitor’s audio input isn’t working).
- Connect a 3.5mm audio cable from your laptop’s headphone jack to your monitor’s audio input jack.
- In your laptop’s sound settings, ensure the correct audio output device is selected. If you’re using a separate cable directly from the laptop’s headphone jack, you’ll likely select your laptop’s internal sound device as the output.
Connecting External Speakers or Soundbars
If your monitor has an audio output jack (often a 3.5mm port), you can connect external speakers or a soundbar to it.
- Connect your laptop to the monitor via HDMI or DisplayPort for audio and video.
- Connect a 3.5mm audio cable from your monitor’s audio output jack to the input jack on your external speakers or soundbar.
- Ensure your laptop is set to output audio to the monitor. The sound will then be passed through the monitor to your external audio system.
- Adjust the volume using either your laptop, your monitor, or your external speakers, depending on how they are configured.
Using USB Audio Devices
Some users prefer to use USB audio interfaces or DACs (Digital-to-Analog Converters) for higher-quality audio.
- Connect your monitor to your laptop via HDMI or DisplayPort for video.
- Connect your USB audio device to a USB port on your laptop.
- In your laptop’s sound settings, select your USB audio device as the default playback device.
- Connect your speakers or headphones to the USB audio device.

Getting audio from your laptop to your monitor is a fundamental aspect of a well-integrated setup. By understanding the role of different cable types, correctly configuring your operating system’s audio settings, and performing basic troubleshooting, you can ensure a seamless audio experience. Whether you’re enjoying movies, gaming, or working on multimedia projects, having your audio routed effectively to your external display will significantly enhance your overall productivity and entertainment. Always refer to your specific laptop and monitor manuals for detailed information regarding their audio capabilities and connection options. With a little attention to detail, you’ll be enjoying rich, clear sound through your monitor in no time.
Why isn’t my monitor producing sound from my laptop?
There are several common reasons why you might not be getting sound from your monitor when connected to your laptop. The most frequent culprit is incorrect audio output selection within your operating system’s sound settings. Your laptop might still be set to output audio through its internal speakers or headphones, rather than the display. Additionally, ensure that your monitor itself has built-in speakers or an audio output port that is being utilized correctly.
Another possibility is that the audio cable you are using is faulty or not fully connected. If you are using an HDMI or DisplayPort cable, these often carry audio signals alongside video. A loose connection at either the laptop or the monitor end, or a damaged cable, can interrupt this signal. It’s also worth checking if your monitor has its own volume control or mute button that might be inadvertently engaged.
What are the different ways to connect my laptop for audio output to a monitor?
The most common and often simplest method is through a single cable that carries both video and audio signals, such as HDMI or DisplayPort. When you connect your laptop to your monitor using one of these cables, the audio signal is typically transmitted directly. Ensure that both your laptop and monitor support the version of HDMI or DisplayPort you are using, and that the cable itself is rated for audio transmission.
Alternatively, if your monitor does not have built-in speakers or an audio output, you might need to use a separate audio cable. This could involve connecting your laptop’s headphone jack (or a dedicated audio output port) to the monitor’s audio input jack using a 3.5mm audio cable. Some monitors also have USB ports that, when connected to your laptop, can enable audio transfer if the monitor has integrated sound capabilities or a USB audio passthrough feature.
How do I select the correct audio output device on my laptop?
To select the correct audio output device on your laptop, you’ll need to access your operating system’s sound settings. On Windows, you can usually do this by right-clicking the speaker icon in the system tray (bottom right corner) and selecting “Open Sound settings” or “Playback devices.” From there, you should see a list of available audio output devices.
Once you’ve opened the sound settings, identify your monitor in the list of playback devices. It might be named after your monitor’s model or simply appear as a digital output. Right-click on the monitor’s output and select “Set as Default Device.” This will direct all audio from your laptop to be sent through that connection.
What if my monitor has speakers, but I’m still not hearing any sound?
If your monitor has speakers and you’ve confirmed your laptop is sending audio to it, the issue might lie with the monitor’s internal settings. First, check if your monitor has its own physical volume control or a mute button. Ensure the volume is turned up and that the monitor isn’t accidentally muted. Many monitors also have an on-screen display (OSD) menu that you can access using buttons on the monitor itself.
Within the monitor’s OSD menu, look for audio settings. You might need to select the correct audio input source if your monitor has multiple input options (e.g., HDMI 1, HDMI 2, DisplayPort). Also, ensure that the monitor’s internal speakers are enabled and not set to an external audio output if you intend to use the monitor’s own sound.
Can I get audio through my monitor if I’m only using a video-only connection like DVI or VGA?
Generally, you cannot get audio through your monitor if you are using a purely video-only connection like DVI or VGA. These older connection standards were designed exclusively to transmit video signals and do not have the capability to carry audio information. Therefore, if your laptop and monitor are connected using only DVI or VGA, you will need a separate audio connection.
To achieve audio output to your monitor’s speakers (if it has them) or through an audio output jack on the monitor when using DVI or VGA, you will need to run a separate audio cable. This typically involves connecting your laptop’s headphone jack to the monitor’s audio input port using a 3.5mm audio cable, or connecting it to external speakers if the monitor doesn’t have audio capabilities itself.
How do I troubleshoot a “no sound” problem when using USB-C for audio and video?
When using USB-C for both audio and video, ensure that your USB-C port on the laptop and the monitor both support DisplayPort Alternate Mode or Thunderbolt, as these protocols are typically required to carry audio signals. Check your laptop and monitor specifications to confirm this capability. Also, verify that the USB-C cable you are using is rated for data, video, and audio transmission; not all USB-C cables are created equal.
Once you’ve confirmed hardware compatibility and cable type, access your laptop’s sound output settings as described previously. Your monitor should appear as an audio output device when connected via USB-C. If it doesn’t, try updating your laptop’s USB-C drivers and graphics drivers, as these can sometimes influence audio routing. Restarting both your laptop and monitor after making any changes is also a good troubleshooting step.
What if my laptop’s built-in speakers are disabled when I connect to the monitor?
It’s common behavior for some operating systems and driver configurations to automatically disable internal laptop speakers when an external audio output device, such as a monitor, is detected and set as the default. This is usually intended to prevent audio from playing from two sources simultaneously. To re-enable your laptop’s speakers, you’ll need to go back into your sound settings and manually set the internal speakers as the default audio output device.
If you wish to have both your laptop speakers and your monitor’s speakers playing audio at the same time, this is often not directly supported by default operating system settings. You might need to explore third-party audio routing software or configure advanced audio settings if your laptop’s sound card and drivers allow for multiple simultaneous outputs, which is a less common setup.
