How to Output Sound with External Monitor Guide
You buy a shiny new external monitor, all crisp resolution and vibrant colors, and you hook it up. Everything looks fantastic. Then you try to watch a video or play a game, and… silence. Utter, deafening silence. It’s like that moment when you finally get that fancy coffee machine, only to realize you forgot to buy beans. So, how to output sound with external monitor becomes the burning question, and frankly, it’s a bigger pain than it should be.
Suddenly, you’re digging through settings you never knew existed, convinced you’ve broken something expensive. I’ve been there, staring blankly at my screen, muttering curses at a perfectly good piece of hardware that’s decided to ignore audio entirely. It’s not just you; this is a surprisingly common frustration.
Figuring out why your monitor isn’t spitting out sound is less about a magic trick and more about understanding a few specific connection types and software hiccups. We’re going to cut through the noise.
Why Your Monitor Isn’t Making Noise
First off, let’s get this straight: not all external monitors have built-in speakers. It sounds obvious, but you’d be surprised how many people buy a display thinking it’s an all-in-one entertainment hub. If your monitor’s spec sheet doesn’t mention ‘speakers’ or ‘audio output,’ congratulations, you just bought a very pretty picture frame. That’s mistake number one, and it cost me around $150 back when I was first setting up my ‘home theater’ PC in a cramped apartment. I thought the slim profile meant it had everything. Nope. Just a sleek chassis and a whole lot of silence.
If your monitor *does* have speakers, the problem usually boils down to one of three things: the physical connection, the operating system’s audio settings, or the monitor’s own internal settings. Honestly, I’ve found the OS settings to be the most frequent culprit. It’s like trying to conduct an orchestra where half the musicians are playing silent instruments because the conductor (your computer) hasn’t told them what to do.
Checking the Cables: The Obvious First Step
This sounds like something out of a bad tech support script, but seriously, check your cables. How are you connecting your computer to the monitor? Are you using HDMI, DisplayPort, or USB-C? These modern connectors often carry both video and audio signals. If you’re using one of these, and you *still* have no sound, it means the signal is either not being sent by your computer, not being received by the monitor, or it’s being rerouted elsewhere.
Using an older DVI or VGA connection? Those only carry video. If you’re rocking a DVI or VGA setup, you’re going to need a separate audio cable, usually a 3.5mm jack running from your computer’s audio-out port to your monitor’s audio-in port. This is where many people get tripped up; they assume the ‘video’ cable will magically carry sound. It won’t. A separate audio cable is non-negotiable in this scenario.

I remember spending an entire Saturday afternoon once, convinced my brand-new graphics card was faulty, all because I’d forgotten to plug in the tiny 3.5mm audio cable when I’d switched from HDMI to a dual-monitor setup with DVI. The video was perfect; the audio was… non-existent. The tiny jack, barely thicker than a headphone plug, held all the power. Funny how something so small can be so vital. It felt like trying to fill a bathtub with a leaky eyedropper.
The Operating System Audio Settings
Now, onto the digital side. Your computer, whether it’s Windows or macOS, has a sound control panel. This is where you tell it where to send the audio. Often, when you connect a new display, especially via HDMI or DisplayPort, your operating system might not automatically switch the default audio output to it. It’s like plugging in a new printer; sometimes you have to tell Windows, ‘Yes, THIS is the printer I want to use.’
Windows Users: Right-click the speaker icon in your system tray (usually near the clock). Select ‘Open Sound settings’ or ‘Playback devices’. You should see a list of all available audio output devices. Look for your external monitor. It might be listed by its model name or simply as ‘HDMI Output’ or ‘DisplayPort Audio.’ If it’s not already set as the default device, right-click it and select ‘Set as Default Device.’ Make sure the volume isn’t muted here, either. I’ve seen countless times where it was set to default, but the volume slider was all the way down. So, two checks: is it default, and is the volume up?
macOS Users: Click the Apple menu, go to ‘System Settings’ (or ‘System Preferences’ on older versions), then find ‘Sound.’ Under the ‘Output’ tab, you’ll see your audio devices. Select your external monitor from the list. Again, check the volume slider. Sometimes, the audio output is set to ‘Internal Speakers’ or another device even after you’ve connected the monitor. It’s a simple oversight, but one that causes hours of frustration if you don’t know where to look.
The sheer number of times I’ve seen people panic because their audio isn’t working, only to find it’s just set to the wrong device in their OS sound settings, is probably in the dozens. For some reason, computers seem to enjoy keeping audio a secret from the devices we actually *want* to hear it from.
Monitor Settings: The Hidden Controls
Some monitors, especially those with more advanced features or built-in soundbars, have their own on-screen display (OSD) menus. These menus are usually accessed via buttons on the monitor itself, often on the bottom or back. Within these menus, there might be an audio setting that needs to be enabled or configured. For example, some monitors have an ‘Audio Output’ setting that you can switch between ‘Internal Speakers’ and ‘External Speakers’ (if you’re connecting a separate soundbar or headphones *to* the monitor).

This is less common for basic monitors but worth checking if you’ve exhausted all other options. It’s like trying to get a smart fridge to connect to Wi-Fi when it’s just a regular fridge; sometimes the feature just isn’t there, or it’s buried so deep you’d need a spelunking guide to find it.
Troubleshooting Specific Connections
HDMI and DisplayPort: As mentioned, these are the most common culprits for carrying audio. If you’re using HDMI and have no sound, double-check that your graphics card drivers are up to date. Outdated drivers can cause all sorts of weird behavior, including audio dropouts or failure to recognize audio streams. A quick update can often fix a multitude of sins. I spent three hours once trying to get audio over HDMI, convinced the cable was bad, only to find out my NVIDIA drivers were about six months out of date. Updating them fixed it instantly. It was less a hardware issue and more a software ‘oops.’
USB-C: This is becoming more prevalent, especially with laptops. If your monitor supports audio over USB-C, ensure your laptop is configured to send audio through that port. Some laptops have specific settings to enable or disable audio over USB-C, and it’s worth checking your laptop’s manufacturer support pages if you’re unsure. It’s a cleaner connection, but sometimes those simpler connections hide their own unique quirks. Think of it like a perfectly designed minimalist kitchen; everything is sleek, but if one tiny screw is loose, the whole aesthetic is ruined.
Audio Extractor Boxes: For the truly adventurous, or for those dealing with older setups or specific signal routing needs, an HDMI audio extractor can be a lifesaver. This little box sits between your source (computer) and your display. It takes the HDMI signal, splits off the audio to a separate output (like optical or analog RCA), and passes the video through to your monitor. This is often overkill, but when you’ve tried everything else, and you absolutely *need* audio from an HDMI source to a device that doesn’t have its own audio output, these boxes are fantastic. I used one for a while when I was running a gaming console through a KVM switch that stripped out audio. It looked like a bunch of wires tangled in a bird’s nest, but it worked flawlessly.
| Connection Type | Audio Capable? | Notes/Troubleshooting | My Verdict |
|---|---|---|---|
| HDMI | Yes | Check OS default, ensure cable is securely plugged in at both ends, update graphics drivers. | Usually the easiest and most reliable if your hardware supports it. |
| DisplayPort | Yes | Similar to HDMI. Ensure correct port is selected in OS sound settings. | Just as good as HDMI for audio, often preferred for higher refresh rates. |
| USB-C (with DP Alt Mode) | Yes | Verify laptop settings and monitor compatibility. May require specific drivers. | Super clean, great for laptops, but double-check device support. |
| DVI | No | Requires a separate 3.5mm audio cable connection. | Old school. Only good if you have to, and requires extra steps for sound. |
| VGA | No | Requires a separate 3.5mm audio cable connection. Picture quality is often inferior. | Avoid if at all possible. Better off using a modern connection. |
When to Consider External Speakers
Let’s be brutally honest here. Most monitor speakers are, to put it mildly, mediocre. They’re often tinny, lack bass, and generally sound like they’re coming from inside a cardboard box. If you’ve gone through all the steps and your monitor *does* have speakers, but the sound quality is still abysmal, it might be time to accept that the monitor’s audio capabilities are just not up to par. This is where the common advice to ‘just use monitor speakers’ falls apart. I’ve tested at least ten different monitors with built-in speakers over the years, and maybe two of them had sound that was genuinely listenable for more than a quick notification. The rest were so bad I seriously considered returning the monitor.
In these cases, the best solution is often to buy a separate pair of computer speakers or a decent set of headphones. You can find surprisingly good budget speaker sets for under $50 that will blow the built-in monitor audio out of the water. You plug these directly into your computer’s audio jack or a USB port, and then you set *that* as your default audio device in your operating system. It’s a simple, effective workaround that sidesteps the monitor’s audio limitations entirely. A friend of mine bought a $500 monitor and then complained about the tinny sound for months, even after I showed him how to fix the OS settings. He finally bought a $40 speaker set, and his whole setup changed. It’s not about the monitor; it’s about the sound output quality. (See Also: How To Monitor My Sleep With Apple Watch )
Is My Monitor’s Audio Port for Input or Output?
Typically, if your monitor has a 3.5mm audio jack and it’s labeled ‘Audio Out,’ ‘Headphone,’ or has a headphone icon, it’s for outputting sound from the monitor to headphones or external speakers. If it’s labeled ‘Audio In,’ it’s for receiving audio from another source, which is less common for general monitor use. Always check the monitor’s manual or labels for clarity.
Can I Use My Monitor’s USB Ports for Audio?
Some monitors have USB hubs. If your monitor has USB-C that supports audio or DisplayPort Alternate Mode, it can carry audio. However, a standard USB-A port on a monitor is usually just for data transfer (connecting keyboards, mice, etc.) and won’t handle audio on its own. You’d still need a separate connection for sound unless the monitor specifically advertises USB audio capabilities.
Why Is My Monitor Volume Control Not Working?
The physical volume buttons on your monitor often only control the monitor’s internal speakers. If your computer isn’t sending audio to the monitor, or if the monitor’s internal speakers are disabled in favor of an audio output port, those buttons might do nothing. The primary volume control for an external monitor’s sound output will almost always be within your operating system’s sound settings.
Final Verdict
So, there you have it. Figuring out how to output sound with external monitor is usually a process of elimination. You check the physical connections, then you dig into your operating system’s audio settings, and if all else fails, you might glance at your monitor’s own cryptic OSD menu. Don’t let the silence get you down; most of the time, it’s a simple setting that’s been overlooked.
My honest advice? If your monitor’s built-in speakers sound like a dying kazoo, just get a cheap pair of external speakers. Seriously. It’s not worth the headache, and the audio quality difference is night and day. You’ll thank yourself for it, and your ears will too.
Consider this your final nudge to tackle that silent screen. Go on, dive into those sound settings. I’m betting you’ll find the culprit hiding in plain sight, just like that stray sock that always disappears in the laundry.
