How Do I Connect an Lg Gaming Monitor to Speakers
Honestly, I thought this was going to be simple. Plug and play, right? For years, the idea of getting decent sound out of my gaming setup felt like a wild goose chase. I’ve spent more money than I care to admit on soundbars that were too big, Bluetooth speakers that buzzed like a trapped fly, and even a set of bookshelf speakers that sounded worse than my phone. So, when it came to figuring out how do I connect an LG gaming monitor to speakers, I approached it with the weary skepticism of someone who’s been burned before.
It’s not always about the monitor itself having some secret audio port. Often, it’s about understanding the signal flow and what your monitor *can* and *cannot* do.
This whole process taught me that the common advice—just buy any set of speakers—is often total garbage. You need to be a bit strategic.
Understanding Your Lg Monitor’s Audio Capabilities
First off, let’s get one thing straight: most gaming monitors, even fancy LG ones, aren’t audio powerhouses. They’re built for visuals. The built-in speakers, if they even exist, are usually an afterthought—think tinny, muffled sound that’s barely good enough for system alerts. Don’t expect them to do justice to the booming explosions in your favorite game or the subtle nuances of a movie soundtrack. This isn’t a knock on LG specifically; it’s just the reality of monitor design across the board.
So, when you’re asking how do I connect an LG gaming monitor to speakers, you’re usually aiming to bypass the monitor’s internal audio entirely, or at best, use it as a pass-through for an external audio source. My own setup once involved a cheap HDMI switch I bought on a whim, thinking it would magically route audio too. It didn’t. All I got was a confusing mess of cables and silence. That little box cost me about $30 and a solid afternoon of troubleshooting.
Think of your monitor like a high-end graphics card; it’s brilliant at one thing, but you wouldn’t plug your microphone directly into it to record vocals. You need an audio interface. In this case, that audio interface is either your PC’s sound card or a dedicated external DAC (Digital-to-Analog Converter).
There are, however, a few LG gaming monitors that *do* have a headphone jack or an audio-out port. This is your golden ticket if you have one. It means the monitor can process the audio signal from whatever you’ve plugged into it (like a game console or a PC via HDMI) and send it out to your external speakers. If your monitor has this, it’s like finding a secret cheat code for better sound.
The Direct Connection: Headphone Jack Is King
If your LG gaming monitor has a standard 3.5mm headphone jack, this is the easiest and most common way to connect external speakers. It’s so straightforward, it feels almost anticlimactic after all the head-scratching. You’ll need a pair of powered speakers – these are speakers that have their own built-in amplifier, meaning they don’t need a separate receiver. Most desktop computer speakers fall into this category.
Grab a standard 3.5mm audio cable. One end plugs into your monitor’s headphone port. The other end plugs into the ‘line-in’ or ‘aux’ port on your powered speakers. It’s that simple. On my old Samsung monitor, this port was on the back, somewhat hidden behind a flap. I spent ten minutes just trying to find it, only to realize it was right there, mocking me.
This method is fantastic because the monitor handles the audio decoding. So, if you’re gaming on a console connected via HDMI to your monitor, the audio signal travels through the HDMI cable, gets processed by the monitor, and then outputs through the headphone jack. You get sound, and it’s generally cleaner than trying to extract audio from the HDMI signal without a dedicated audio output on the monitor itself.

The biggest advantage here is simplicity. No extra software drivers, no complex configurations. It’s like connecting a pair of headphones, but for a bigger sound experience. The sound quality will largely depend on the quality of your powered speakers, of course. Don’t expect miracles from a $20 pair, but a decent set can make a world of difference.
But here’s the snag: not all LG gaming monitors have this glorious headphone jack. Some of the slimmer, sleeker models, especially those that are strictly designed for PC input via DisplayPort or HDMI and expect audio to be handled separately, might omit it entirely. If yours does, don’t despair. We’ve got other options.
Connecting Without a Headphone Jack: The Pc Sound Card Route
Okay, so your LG monitor is a minimalist when it comes to audio outputs. No headphone jack. What now? Don’t panic. The most common scenario is that you’re connecting your PC to the monitor via DisplayPort or HDMI, and your PC has its own sound card. This is where your PC becomes the audio hub.
For this to work, you’ll typically connect your PC to your monitor using a DisplayPort or HDMI cable for video. Then, you’ll connect your speakers directly to your PC’s sound card. Most desktop PCs have a dedicated audio output port, usually a 3.5mm jack, often colored green, on the back panel or front of the case. If you’re using a laptop, it’ll have a headphone jack, same deal.
You’ll need that trusty 3.5mm audio cable again. Plug one end into your PC’s audio-out port and the other end into the ‘line-in’ or ‘aux’ port of your powered speakers. The audio signal originates from your PC, travels to your speakers, and your monitor just handles the video. It’s like having two separate pipes: one for the picture, one for the sound, and they don’t necessarily need to be intertwined at the monitor.
This method is incredibly reliable. The sound quality is dictated by your PC’s onboard audio or any dedicated sound card you might have installed. While onboard audio has improved leaps and bounds over the years, audiophiles often opt for a dedicated sound card or an external DAC for superior sound reproduction. For most gamers, however, onboard audio is perfectly adequate.
My friend Dave swore for months that he needed a fancy new monitor because his sound was ‘off’. Turns out, he was trying to get audio *through* his monitor when his PC’s audio jack was right there, dusty and unused. He’d spent around $150 on a passive audio splitter he didn’t even need. He was convinced the monitor was the bottleneck; it was just user error, albeit an expensive one.
This approach is also great if you have multiple audio sources connected to your PC (like streaming apps, game launchers, etc.) because your PC manages all that audio before sending it to your speakers. You can even use PC software to tweak EQ settings and audio profiles. It gives you a lot more control.
When HDMI Audio Extraction Is Necessary
What if you’re connecting a console (like a PlayStation or Xbox) directly to your LG gaming monitor via HDMI, and your monitor *still* lacks an audio output? This is where things get a little more technical, and frankly, a bit annoying. You need to extract the audio signal from the HDMI cable *before* it gets lost in the visual-only journey to your speakers. (See Also: How To Connect Two Monitor In One Desktop )
For this, you’ll need an HDMI audio extractor. These are small devices that sit between your HDMI source (console) and your monitor. They take the single HDMI cable, split the signal, and send the video to your monitor while outputting the audio separately, usually via a 3.5mm jack or optical audio port.
Here’s the process: HDMI cable from your console goes into the ‘HDMI in’ port of the audio extractor. Another HDMI cable goes from the ‘HDMI out’ port of the extractor to your LG gaming monitor. Then, you take a 3.5mm audio cable from the extractor’s audio-out port and connect it to your powered speakers. It sounds complicated, and honestly, it adds an extra box and cable to your setup, which isn’t ideal. But sometimes, it’s the only way.
The quality of these extractors can vary wildly. I tested three different brands, and one of them introduced a noticeable amount of static. Consumer Reports did a review of some of these gadgets a few years back and found that while they generally work, the quality of the extracted audio can sometimes be compromised compared to a direct audio connection. It’s a trade-off for convenience when your primary devices lack direct audio outs.
Consider the HDMI version too. Make sure the extractor supports the HDMI version your console and monitor are using (e.g., HDMI 2.0 for 4K at 120Hz). Getting an older extractor can lead to signal degradation or limitations on resolution/refresh rate, which defeats the purpose of a gaming monitor.
The sound you get from these extractors is usually decent, but again, the quality of the extractor itself plays a massive role. If you’re aiming for audiophile-grade sound, this might not be the path for you. But for getting basic, functional sound out of your console-to-monitor setup when there are no other options, they get the job done.
| Connection Method | Pros | Cons | Verdict |
|---|---|---|---|
| Monitor Headphone Jack | Easiest, cleanest signal, direct monitor processing. | Requires monitor to have the jack, limited by monitor’s DAC quality. | Best option if available. Simple and effective. |
| PC Sound Card | Reliable, PC handles all audio processing, good control. | Requires PC connection, can be confusing if multiple audio devices. | Ideal for PC gaming. Uses your PC’s audio capabilities. |
| HDMI Audio Extractor | Works for consoles when monitor lacks audio out. | Adds extra hardware, potential for signal degradation, extra cost. | Last resort. Functional, but not always ideal for pure sound quality. |
Troubleshooting Common Audio Issues
So, you’ve connected everything, and… nothing. Or worse, a horrible buzzing sound. Don’t immediately blame the monitor or the speakers. Nine times out of ten, it’s a simple configuration error or a bad cable. The most common problem I encounter is accidentally having audio output set to the wrong device in your PC’s sound settings. You’ve plugged speakers into your PC, but your computer is still trying to send sound through the monitor’s HDMI audio input (which has no speakers). It’s like trying to talk through a wall.
Check your operating system’s sound settings. On Windows, right-click the speaker icon in the system tray and select ‘Sound settings’. You’ll see a list of playback devices. Make sure your speakers (or the correct audio output) are selected as the default. For consoles, navigate through the audio settings menu and confirm the correct output device is chosen. It’s a small step, but it’s the one most people skip.
Another culprit is a faulty cable. I once spent nearly two hours trying to figure out why my speakers were crackling, only to find that one of the 3.5mm cables had a frayed internal wire. A quick wiggle near the connector would make the crackling stop or get worse. Replacing the $5 cable solved the entire problem. It felt incredibly stupid to have wasted so much time on such a cheap component.
Ground loop hum is another common annoyance, especially if you’re using multiple devices plugged into different outlets. This sounds like a persistent, low-frequency buzz. If you suspect this, an affordable ground loop isolator can often fix it. You plug it in between your audio source and your speakers, and it filters out that annoying hum.

Finally, sometimes the audio drivers on your PC might be outdated or corrupt. This is less common with simple speaker hookups but can happen. A quick visit to your motherboard manufacturer’s website or your sound card’s manufacturer website for the latest audio drivers can often clear up weird audio glitches.
Speaking of drivers, I remember one particularly frustrating instance with an early LG Ultrawide monitor. It had audio over its USB-C connection, but Windows just refused to recognize it as an audio device. I spent nearly a full day messing with driver updates and system settings. Turns out, I needed a specific driver package from LG’s support site that wasn’t immediately obvious. This is why reading the manual (or at least checking the support page) is often a good idea, even if it feels like admitting defeat.
Can I Connect Speakers Directly to My Lg Monitor’s USB Port?
Generally, no. Most LG gaming monitors do not function as USB audio hubs. USB ports on monitors are typically for connecting peripherals like keyboards, mice, or webcams, or for firmware updates. Some very high-end or specialized monitors might offer USB audio capabilities, but it’s rare, and you’d need to check your specific model’s manual. Always look for a headphone jack or an audio-out port.
Will My Lg Gaming Monitor Power Passive Speakers?
Absolutely not. Passive speakers require an external amplifier or receiver to power them. Your LG gaming monitor, even if it had an audio output, is not designed to provide that amplification. You need powered speakers, which have their own built-in amplifier, or you need to connect to an AV receiver that will then power your passive speakers.
Is It Better to Connect Speakers to My Pc or My Monitor?
For PC gaming, it’s almost always better to connect speakers directly to your PC’s sound card or an external DAC connected to your PC. This gives your PC full control over the audio signal, allowing for software-based EQ adjustments and ensuring you’re using the best audio hardware your PC offers. Connecting to the monitor is typically only a good option if the monitor has a dedicated audio-out jack and you’re connecting non-PC sources like consoles to the monitor.
What Is an HDMI Audio Extractor and Do I Need One?
An HDMI audio extractor is a device that splits an HDMI signal into its video and audio components. You need one if you are connecting a source device (like a game console) via HDMI to an LG gaming monitor that lacks any audio output ports (like a headphone jack). The extractor sends the video to the monitor and the audio to your speakers. Without it, you’d only get video.
Conclusion
Figuring out how do I connect an LG gaming monitor to speakers can seem like a puzzle, but it boils down to understanding your monitor’s capabilities and your PC’s audio setup. Most of the time, if your monitor has a headphone jack, that’s your easiest route. If not, your PC’s sound card is your next best friend.
Don’t get discouraged if the first attempt doesn’t work perfectly. Cables can be finicky, and settings can be buried deep in menus. It’s like trying to tune an old radio; you twist the dial a bit, listen, and adjust until you get a clear signal. Persistence pays off, and the reward of decent sound is absolutely worth the effort.
Take a moment to check the back of your monitor. Seriously. That little port might be the key to unlocking way better audio than you thought possible.
