How to Play Sound Through External Monitor Easily
So, you’ve got this big, beautiful external monitor, right? Looks great for movies, gaming, or just spreading out your work. But then you try to play some music, and… crickets. Nothing. Just the hum of your computer fan. It’s infuriating, isn’t it? We’ve all been there, staring at a gorgeous display that’s deaf in one ear.
Wondering how to play sound through external monitor shouldn’t feel like deciphering ancient runes. It’s a common problem, and frankly, one that manufacturers could make a lot clearer. I’ve wasted countless hours fiddling with settings that felt like they were designed by sadists.
Honestly, the solution is often laughably simple, yet infuriatingly hidden. Sometimes it’s just a cable choice. Other times, it’s a quick trip into Windows or macOS settings. Let’s cut through the noise.
The Cable Conspiracy: Your First Hurdle
Look, I’ve seen people spend hours in their sound settings, drivers, and control panels, only to realize their monitor doesn’t even have built-in speakers. Or worse, they’re using a cable that *looks* like it should carry audio but doesn’t. HDMI and DisplayPort are generally your friends here, as they *can* carry audio signals alongside video. But not all devices are created equal, and sometimes, the monitor itself is the bottleneck.
My first big monitor purchase, a slick 27-inch behemoth from a brand I won’t name (but they make a lot of TVs), promised the world. It had HDMI, USB-C, the works. Plugged it in, expecting glorious cinematic sound to blast out. Nada. Turns out, while the HDMI *port* was there, the internal audio hardware for that particular model was purely decorative. I felt like such an idiot, having spent nearly $400 on a display that was effectively mute. That was after my third attempt to get it working, convinced it was a software issue.
So, step one is always to verify your monitor *actually has speakers*. Most do if they have built-in sound bars or grille-like openings on the front or bottom. If it’s just a flat panel with a stand, chances are it’s video-only. Don’t assume. Check the manual. Google the model number and ‘speakers’.
When the Monitor Has Speakers, but Plays Nothing
Okay, so you’ve confirmed your monitor *does* have speakers. Great. Now, why isn’t any sound coming out? This is where we get into the nitty-gritty of your computer’s audio output settings.
Think of your computer like a busy train station, with audio signals being the passengers. You need to tell the station master (your OS) which platform (your monitor) the passengers should go to. If you don’t explicitly tell it to send sound to the monitor, it’ll just keep sending it to your default, probably your laptop speakers or some ancient desktop speakers.

Right-click the speaker icon in your system tray (bottom right of the screen). Select ‘Open Volume Mixer’. You’ll see sliders for your overall volume and for individual applications. But more importantly, look for the ‘Output device’ selection. This is where you choose where your sound goes. Your external monitor, if connected properly, should appear here as an audio output device, often listed by its model name or as something like ‘Digital Output (HDMI)’ or ‘DisplayPort Audio’. Select that.
If it’s not there, or if it’s greyed out, we need to go deeper. Head to ‘Sound Settings’ (you can search for it in the Start menu). Under ‘Output’, make sure your monitor is selected as the default playback device. If you don’t see it at all, right-click in the empty space of the ‘Output devices’ list and select ‘Show Disabled Devices’ and ‘Show Disconnected Devices’. Sometimes they just get switched off.
Mac Users: System Preferences is Your Control Panel
On macOS, it’s similar. Go to ‘System Preferences’ (or ‘System Settings’ in newer versions) > ‘Sound’. Click on the ‘Output’ tab. You should see a list of available audio devices. Your external monitor should be listed here. Click on it to set it as the default output. If it’s not showing up, try disconnecting and reconnecting the monitor, or even restarting your Mac. I’ve had it stubbornly refuse to appear after a quick connection, only to pop up after a full reboot.
This process is less about ‘fixing’ a broken device and more about correctly routing the existing signal. It’s like trying to send a letter to the wrong address; the letter isn’t broken, you just need to fix the address. The visual clutter of all those cables and ports can make you overthink the software side, when it’s often just a simple selection. I spent about 45 minutes once, convinced a firmware update was needed, only to find it was set to ‘mute’ in the monitor’s OSD menu!
The Displayport vs. HDMI Debate: Does It Matter for Sound?
When figuring out how to play sound through external monitor, the cable you use can sometimes be the deciding factor. While both HDMI and DisplayPort are designed to carry audio, there are nuances.
Generally, if your monitor has speakers and you’re using an HDMI cable, audio should work out of the box. Same goes for DisplayPort. But I’ve run into situations, particularly with older equipment or very specific monitor models, where one might be finicky and the other isn’t. It’s like trying to fit a square peg into a slightly non-square hole. Sometimes it jams, sometimes it slides right in.
My personal anecdotal evidence suggests DisplayPort is often more robust for high-bandwidth signals, including audio, especially when dealing with higher refresh rates or resolutions. However, HDMI has broader compatibility across a wider range of devices, from gaming consoles to older laptops. If one isn’t working, and your monitor supports both, swapping the cable is a ridiculously simple troubleshooting step that too many people skip. I’ve seen people throw away perfectly good monitors because they were using a DVI cable, which, as we all know, is video-only and completely useless for audio. That’s a classic ‘user error’ mistake, but it happens. (See Also: How To Switch An Acer Monitor To Hdmi )
A quick check of your monitor’s manual or specifications online will tell you exactly which ports support audio output. Don’t guess. Don’t assume. Look it up. The manual is your best friend when you’re wrestling with technology that seems intent on defying logic.
This brings us to an interesting point: some older monitors might have an audio-in jack. This is for when your graphics card or computer doesn’t send audio over its video cable (like DVI or older VGA). You’d then need a separate 3.5mm audio cable from your computer’s headphone jack to the monitor’s audio-in port. It feels archaic now, but for certain setups, it’s the only way. It’s like having to bring your own extension cord to a power outlet – inconvenient, but functional.
What About Monitor Audio Settings? (yes, They Exist)
This is the part that catches people off guard. Most external monitors that have speakers also have their own On-Screen Display (OSD) menu. You access this using buttons usually located on the bottom or back of the monitor bezel. Within this menu, there are often audio settings. And guess what? Some of them can be set to ‘mute’ or have volume levels cranked down to zero.
I once spent an hour trying to get sound out of a brand new monitor, only to find the volume in the monitor’s own menu was set to 5. FIVE. After I cranked that up, the computer’s audio settings suddenly started behaving. It was utterly bizarre, like the monitor was saying, “I *could* play sound, but I’ve decided not to, just to mess with you.”
So, when you’re troubleshooting, don’t just live in your computer’s settings. Cycle through your monitor’s OSD menu. Look for ‘Audio’, ‘Sound’, or ‘Volume’ sections. Make sure the volume is up and that it’s not set to an input or output that doesn’t exist. It sounds obvious, but in the heat of troubleshooting, the simplest things are often overlooked. It’s similar to how a chef might forget to turn on the oven before putting the roast in – a fundamental step that, when missed, leads to a lot of confusion.
Remember that the monitor’s OSD is a separate system from your computer’s. They can sometimes conflict or, as in my case, one can override the other in a way that isn’t immediately intuitive. It’s a dual control system, and both sides need to be configured correctly.
Troubleshooting Common Issues: When All Else Fails
If you’ve gone through all the above and still have no sound from your external monitor, it’s time for some more drastic measures. First, test with a different cable. Seriously, cables go bad, and you might have a faulty HDMI or DisplayPort cable that’s only passing video.
Next, try a different port on your computer if available. Maybe the HDMI or DisplayPort on your graphics card or motherboard is acting up. This is where you start isolating variables, like a detective trying to figure out who’s been messing with the wiring in a building. (See Also: How To Monitor My Sleep With Apple Watch )
If you have another device handy, like a laptop or even a gaming console, try connecting that to your monitor with the same cable. If you get sound then, the problem is almost certainly with your computer’s settings or drivers. If you *still* get no sound, the monitor itself is the culprit, or the cable is definitely bad.
Driver Nightmares
Graphics card drivers are notorious for causing audio issues, especially if they’re outdated or corrupted. Open your Device Manager (search for it in Windows). Under ‘Sound, video and game controllers’, you’ll see your audio devices. Right-click your graphics card’s audio device (often listed as NVIDIA High Definition Audio or AMD High Definition Audio) and select ‘Update driver’. If that doesn’t work, try ‘Uninstall device’ and then restart your computer. Windows will usually reinstall the driver automatically. Sometimes, you might need to download the latest drivers directly from NVIDIA’s or AMD’s website. This is a common fix for a lot of weird audio glitches across various display setups. I’ve seen corrupted audio drivers cause sound to cut out intermittently, not just fail entirely.
The FAQ Section: Quick Answers to Lingering Questions
My Monitor Has Speakers but I Don’t See It in the Sound Settings?
This usually means the cable isn’t transmitting audio, or the monitor’s audio feature is disabled. Ensure you’re using HDMI or DisplayPort. Try showing disabled/disconnected devices in your sound settings. Also, check your monitor’s OSD menu to ensure audio is enabled and volume is up.
Can I Use a USB-C Cable for Audio and Video to My Monitor?
Yes, if both your computer and your monitor support DisplayPort Alternate Mode over USB-C. This is a common feature on modern laptops and many high-end monitors. It’s a single cable solution that’s incredibly convenient.
My Monitor Has an Audio-in Port, What Do I Do?
If your monitor has an ‘Audio In’ jack (usually a 3.5mm headphone jack port), and you’re not getting audio via HDMI or DisplayPort, you’ll need to connect a standard 3.5mm audio cable from your computer’s headphone output to the monitor’s audio-in port. Then, select the ‘Line In’ or ‘Audio In’ as your audio output device in your computer’s sound settings.
Verdict
Figuring out how to play sound through external monitor often boils down to a few key checks: confirm the monitor has speakers, use the right cable (HDMI or DisplayPort), and tell your computer to send audio to the correct output device. It’s rarely a deep technical problem, more like a communication breakdown between your PC and the display.
Don’t get bogged down in driver updates or complex settings if you haven’t first confirmed the basic connections and selections. I’ve seen people spend three days trying to fix a software issue when all they needed was to plug their HDMI cable in all the way, or select the monitor from a dropdown menu. It happens.
If you’ve tried all this and it’s still silent, and you’ve tested with another device and cable, then it’s sadly possible your monitor’s audio component has finally given up the ghost, or there’s an internal fault. But before you declare it dead, give it one last wiggle of the cable and a thorough check of every single menu option. Sometimes, persistence (and a bit of frustration) pays off.
