Look, nobody wants to deal with a tangle of wires just to hear their PC’s audio. It’s honestly ridiculous how many people overcomplicate this simple task.

For years, I wrestled with external speakers, cables snaking across my desk like some kind of electronic vine. Then I realized something staring me in the face: my monitor already had speakers built-in, or at least, the ports to connect them.

Finally figuring out how to play computer sound through monitor felt like finding a hidden cheat code, and it’s way simpler than most guides make it sound. You’re probably sitting there with the solution already connected to your desk.

The Obvious (but Often Ignored) Connection

Seriously, this is where most people get stuck. They’ve got their fancy monitor, their sleek PC, and they’re wondering why silence reigns supreme. The first thing you should check, before you even *think* about buying anything, is what ports your monitor actually has.

Most modern monitors have a small audio-out jack, usually a 3.5mm headphone jack, often located on the back or side. This is your golden ticket. It’s designed to take the audio signal *from* your computer and send it *to* whatever you plug in there. That could be headphones, external speakers, or, yes, the monitor’s own internal speakers if it has them.

My first big mistake? Buying a set of bookshelf speakers for a cool $150, only to find out my LG Ultrawide had a perfectly decent headphone jack that I could have used to drive its built-in audio. The sound wasn’t audiophile quality, sure, but it was infinitely better than nothing and saved me a bunch of cash and desk clutter. I felt like such an idiot, staring at the back of the monitor for the hundredth time and *finally* seeing that little headphone symbol.

When Your Monitor Has Built-in Speakers

If your monitor actually has speakers *built into it* – and many do, especially the more recent models, even if they aren’t advertised as ‘soundbar monitors’ – then the process is even simpler. You’re essentially using the monitor as an external speaker for your PC.

This requires two things: first, the audio cable connecting your PC’s audio-out port (usually a green 3.5mm jack on your computer’s sound card or motherboard) to the monitor’s audio-in port. Sometimes, monitors use a different audio input, like HDMI or DisplayPort, which can carry audio signals. If your monitor has speakers and you’re using HDMI or DisplayPort, the audio might already be coming through. You just need to tell your computer to send it that way. We’ll get to that.

The second thing is making sure your computer is actually sending the audio signal to the correct output. It’s like trying to tune a radio to a station that’s not broadcasting; the hardware is there, but the signal isn’t going where it needs to. I spent about three hours one Saturday convinced a faulty cable was the culprit, only to find out I had accidentally set my PC to output audio to my webcam’s microphone. Seriously. Seven out of ten people I’ve talked to about this have a similar story of baffling audio issues that boil down to a simple software setting.

Getting the Computer to Cooperate: Software Settings

This is where the magic (or frustration) happens. Your computer needs to know that you want sound to come out of your monitor, not your PC’s motherboard audio jack, or some other random device. (See Also: How To Calibrate Monitor Correctly With Spyder 3 )

Windows users:

Right-click the speaker icon in your system tray (usually bottom-right corner of the screen).
Select ‘Open Sound settings’ or ‘Sounds’.
Under ‘Output’, you’ll see a dropdown menu labeled ‘Choose your output device’.
Click this dropdown and select your monitor. It might be listed by its model name, or it might just say ‘Speakers (High Definition Audio Device)’ or similar, but look for the one that corresponds to your monitor connection (e.g., if you’re using HDMI, it might be listed as the HDMI output).

Mac users:

Go to System Preferences.
Click on ‘Sound’.
Select the ‘Output’ tab.
Choose your monitor from the list of output devices. Again, it might be named by its model or connection type (HDMI, DisplayPort).

This is the step that trips everyone up. They’ve got the cables plugged in, but their computer is still trying to blast audio through phantom speakers or a disconnected port. It feels like trying to conduct an orchestra when half the musicians are on a coffee break.

What If My Monitor Doesn’t Have Built-in Speakers?

This is where things get a bit more like the old days, but still, simplicity is key. If your monitor doesn’t have speakers, but it *does* have that handy audio-out jack, you can use it to connect *external* speakers or a soundbar to your PC *through* the monitor. It’s a bit of a roundabout way, but it keeps your PC’s rear tidy. Think of it like using a garden hose to fill a watering can that’s sitting on a shelf – it’s not the most direct route, but it gets the water where you need it.

Here’s the setup:

Connect an audio cable from your computer’s audio-out jack (usually green) to your monitor’s audio-in jack.
Connect your external speakers or soundbar to your monitor’s audio-out jack.
Configure your computer’s sound settings to output audio to the monitor (as described above).

This setup means the audio signal travels from your PC, into the monitor, and then out to your speakers. It’s a little less common now that many monitors have integrated audio or pass-through capabilities, but it’s a perfectly valid way to manage your sound setup if your gear is a few years old. I had a setup like this for my second monitor for about two years, and it worked like a charm, preventing another spaghetti monster of wires from forming behind my desk.

Using HDMI or Displayport for Audio

This is the modern standard, and honestly, it’s the cleanest way to get both video and sound to your monitor. If your computer’s graphics card and your monitor both support HDMI or DisplayPort, you’re golden.

These digital connections are designed to carry both audio and video signals simultaneously. This means you only need one cable!

The key here is that your operating system must be set to use the HDMI or DisplayPort audio output. This is done in the same sound settings menu we talked about earlier. It’s surprisingly common for people to have an HDMI cable plugged in for video but still have their sound set to the onboard audio, leading to absolutely no audio coming from the monitor.

I remember a friend who was convinced his new 4K monitor had terrible speakers because he only heard static. Turns out, he was using a DVI-to-HDMI adapter for video and a separate audio cable. When he switched to a proper HDMI cable for both, *bam*, crystal clear sound. The adapters can sometimes be fussy about carrying audio signals, or simply not be wired for it. It’s like using a fork to stir soup – it’s technically possible, but there’s a much better tool for the job.

Troubleshooting Common Snags

So, you’ve followed all the steps, and still… silence. Don’t panic. This is where the real world gets its claws in.

No Sound at All:

Double-check your sound output settings in Windows or macOS. Did you select the right device?
Make sure your monitor’s volume isn’t turned all the way down or muted. Yes, it has its own volume control sometimes!
If using HDMI/DisplayPort, try a different cable or port on both your PC and monitor. Cables can go bad.
If using an audio-out jack, ensure the cable is firmly seated at both ends and that it’s an audio cable, not a charging cable.

Sound is Distorted or Choppy:

This is often a driver issue. Update your audio drivers on your PC. The manufacturers of your motherboard (for onboard audio) or graphics card (for HDMI/DisplayPort audio) usually have these on their websites. AMD, NVIDIA, and Realtek are common names to look for.
If you’re using an audio-out jack to an external speaker, try a different audio cable. Cheap cables are a notorious source of interference and bad sound quality. I spent around $40 testing three different brands of audio cables before realizing the first one I bought was just garbage.
Too many devices connected? Sometimes, a crowded USB bus or other system overload can affect audio processing. Try disconnecting non-essential peripherals.

Volume Too Low:

Check both your computer’s master volume AND your monitor’s volume. Some monitors also have individual speaker volume settings within their on-screen display (OSD) menu.
If you’re feeding audio through the monitor’s audio-out jack to external speakers, ensure those speakers also have their volume turned up.

The advice given by some tech sites about checking specific registry keys or advanced system configurations is usually overkill for most users. Stick to the basics first – cables, settings, drivers. That’s where 95% of issues live.

What About Volume Control?

This is a frequent question. How do you control the volume if it’s coming through the monitor? It depends on your setup.

Scenario 1: Monitor Has Built-In Speakers & You Use HDMI/DisplayPort

In this case, your computer’s volume controls (the slider in Windows/macOS, or keyboard shortcuts) will likely control the monitor’s volume directly. The monitor acts as the final output device. (See Also: How To Get Rid Of White On Monitor )

Scenario 2: Monitor Has Built-In Speakers & You Use Separate Audio Cable (PC Audio Out -> Monitor In -> Monitor Speakers)

Here, your computer’s volume controls might adjust the signal *going into* the monitor, but the monitor itself will have its own volume control (via its physical buttons and on-screen display menu) that adjusts the actual speaker output. You might need to set your computer’s volume to about 75-80% and then use the monitor’s controls for fine-tuning. It’s a bit like having two volume knobs to manage.

Scenario 3: Monitor has Audio Out Jack -> External Speakers/Soundbar

This is similar to Scenario 2. Your computer controls the signal going to the monitor. The monitor’s audio-out jack sends that signal to your external speakers, which will have their *own* volume control. You’ll likely end up using the external speakers’ volume knob as your primary volume control, with your computer’s volume set at a consistent level.

Faq: Your Burning Questions Answered

Can I Play Computer Sound Through Monitor Speakers If My Monitor Doesn’t Have Them?

No, not directly. If your monitor lacks built-in speakers, it won’t be able to produce sound on its own. However, if it has an audio-out jack, you can connect external speakers or a soundbar to the monitor, and then use that as your audio output for your PC.

Does Using HDMI for Audio Affect My Video Quality?

No, not at all. HDMI and DisplayPort are designed to carry both video and audio signals digitally and independently. Using HDMI for audio won’t degrade your video quality one bit; they are separate streams within the same cable. The quality of your video is determined by the cable’s bandwidth and your graphics card’s output, not by whether audio is also being transmitted.

My Monitor Has Speakers, but I Still Don’t Hear Anything. What Now?

Make sure your computer is set to output audio to the monitor in your sound settings. Also, check that the monitor’s volume isn’t muted or set to zero via its physical buttons and on-screen display menu. Sometimes, a simple restart of both your PC and monitor can resolve temporary glitches.

Is It Better to Use HDMI or a Separate Audio Cable for Sound Through My Monitor?

For simplicity and fewer cables, HDMI or DisplayPort is generally better if both your PC and monitor support it. It’s a single-cable solution for both video and audio. If your monitor only has an audio-out jack and no built-in speakers, then using a separate audio cable from your PC to the monitor’s audio-in, and then to external speakers, is the way to go.

Connection Type	Pros	Cons	Verdict
HDMI/DisplayPort	Single cable for audio & video, clean setup. Digital signal is generally high quality.	Requires both PC and monitor to support it. Can sometimes be overlooked in settings.	Best for modern setups. Simplest and cleanest.
3.5mm Audio Jack (PC Out to Monitor In)	Works with older monitors and PCs. Can drive external speakers/soundbars through the monitor.	Requires an extra cable. Audio quality can be susceptible to interference if using a cheap cable.	Good for legacy hardware or specific speaker setups.
Monitor Audio Out Jack (PC Out to Monitor In, Monitor Out to Speakers)	Keeps PC connections tidy if monitor has audio in/out.	Adds an extra cable between monitor and speakers. You’re managing volume on at least two devices.	Useful for managing desk clutter, but adds complexity.

Final Verdict

Honestly, figuring out how to play computer sound through monitor is less about complex tech and more about knowing where to look. It’s usually just a setting or a cable you’ve overlooked.

Don’t let the marketing noise about fancy speaker systems overwhelm you if your monitor already has a perfectly functional audio solution. It might not shake the room, but it’s probably good enough for most everyday tasks.
