Do you have a monitor with built-in speakers but can’t get any sound out of it? You’re not alone. HDMI and DisplayPort connections carry audio, yet Windows often picks the wrong output device or simply doesn’t show your monitor speakers at all. By the end of this guide you’ll know exactly which settings to check, how to make your monitor the default audio device, and what to do when nothing seems to work. Let’s fix that silence.
Why Monitor Speakers Might Not Work as Expected
Before diving into steps, it helps to understand the two most common reasons monitor speakers stay silent:
- Windows is routing audio to a different device. Your PC might be sending sound to built-in laptop speakers, a headset, or external speakers instead of the monitor.
- The connection type doesn’t support audio. Not every cable carries sound. DVI and VGA never do. Some DisplayPort cables or adapters also skip audio — especially older or passive adapters.
In practice, the easiest fix is telling Windows “this is your new speaker” (steps below). If that still fails, you probably have a hardware or driver issue.
Step 1: Connect Your Monitor Correctly
Check that your monitor’s audio can actually reach your PC. Modern monitors use these cables:
| Cable / Port | Carries Audio? | Notes |
|---|---|---|
| HDMI | Yes | Most common. Works with GPU or motherboard HDMI. |
| DisplayPort | Usually yes | Confirm both your GPU and monitor support audio over DP. |
| USB-C / Thunderbolt | Yes | Common on newer laptops and monitors with built-in USB hubs. |
| DVI, VGA | No | No audio signal possible. You’d need a separate audio cable. |
If your monitor has a 3.5 mm audio‑in port (often labelled “Audio In” or “Line In”), you can connect it directly to your PC’s headphone/speaker jack with a standard auxiliary cable. That bypasses HDMI/DP audio entirely.
A common mistake is plugging a monitor into a graphics card’s DisplayPort that was not designed for audio output. Most modern GPUs do pass audio, but some budget or older cards don’t. When in doubt, try an HDMI connection first.
Step 2: Access Windows Sound Settings (Quick Route)
- Right-click the speaker icon in your system tray (bottom‑right of the taskbar).
- Select Sound settings (on Windows 11) or Open Sound settings (Windows 10).
This opens the main Sound page. If you prefer the classic control panel, right‑click the speaker icon and choose Sounds instead — that opens the Playback tab directly.
Step 3: Select and Enable Your Monitor as the Default Playback Device
Once you’re in Sound settings, look under Output or Choose your output device. Your monitor should appear as an option, often named after the brand (e.g., “Dell S2721QS” or “LG UltraFine”) or as “Digital Audio (HDMI/DisplayPort)”.
- If you see your monitor, click it and select Set as default.
- If you don’t see it, scroll down and click Sound Control Panel (under “Advanced” on Windows 11) or go directly to the Playback tab.
In the Playback tab:
- Right‑click any empty space and check Show Disabled Devices and Show Disconnected Devices. Your monitor may appear greyed out.
- Right‑click the monitor entry and choose Enable (if disabled).
- Then right‑click again and select Set as Default Device.
- Click Apply then OK.
After that, play any audio — a YouTube video, a system sound, or a music app. Sound should now come from your monitor speakers.

Step 4: Fine‑Tune Speaker Properties
Default volume isn’t always optimal. To adjust:
- In the Playback tab, right‑click your monitor device and select Properties.
- Go to the Levels tab. Make sure the speaker icon isn’t muted (no red circle) and drag the slider to a comfortable level — around 60–80 % is a good starting point.
- Switch to the Enhancements tab. If your monitor supports it, enable Loudness Equalization to boost quieter content. Some monitors also offer Virtual Surround — toggle it on and test.
- Open the Advanced tab. Here you can raise the Default Format (sample rate and bit depth). A higher quality like 24 bit, 48000 Hz (Studio Quality) often improves clarity. Click Test to hear a sample.
A quick note: not all monitor speakers can reproduce deep bass. Turning on loudness equalization can help, but it won’t turn tiny drivers into a subwoofer.
Step 5: Test Your Audio Output
The fastest test is right inside the Properties window:
- On the Advanced tab, click Test — you should hear a left‑channel tone, then a right‑channel tone.
- If you hear both, your monitor speakers are working correctly.
- If only one channel plays, check the Levels > Balance slider — it may be skewed to one side.
You can also test with a YouTube video or the Windows troubleshooter:
- Go to Settings > System > Troubleshoot > Other troubleshooters and run Audio.
- The troubleshooter will reset the default device and check drivers.

Troubleshooting Common Monitor Speaker Issues
If you’ve done the steps above and still get silence, work through this checklist:
No Sound at All
- Check the monitor’s own volume. Many monitors have a physical mute button or a volume rocker on the side or bottom bezel. Look for speaker icons on the monitor’s OSD (on‑screen display) menu.
- Try a different cable. HDMI cables can fail intermittently. Swap with another known‑good cable.
- Test the monitor with a different device (e.g., a laptop). If it works there, the issue is your PC’s settings or drivers.
Sound Is Quiet or Muffled
- Monitor speakers are physically small — they have limited bass and volume. That’s normal. If the sound seems unusually quiet, check the Levels tab in Windows (Step 4) and raise the slider.
- Disable any “night mode” or “quiet mode” in your monitor’s OSD.
Sound Crackles or Drops Out
- This often points to a driver issue or interference. Update your audio and graphics drivers (see below).
- If you’re using a long HDMI cable (10 m+), signal degradation can cause audio glitches. Consider a shorter cable or an active repeater.
Windows Does Not Detect the Monitor Speakers at All
- Right‑click in the Playback tab and select Show Disabled Devices and Show Disconnected Devices again — sometimes the monitor appears only after a fresh cable reconnection.
- Reboot your PC with the monitor powered on and connected.
Update Your Audio Drivers
Outdated or missing drivers are a common culprit, especially after a major Windows update. Here’s how to update:
- Press Win + X and choose Device Manager.
- Expand Sound, video and game controllers.
- Look for your monitor’s audio driver (e.g., “NVIDIA High Definition Audio” or “AMD High Definition Audio Device” or “Intel Display Audio”). If you see a yellow exclamation mark, the driver needs attention.
- Right‑click it and select Update driver > Search automatically for drivers.
You can also download the latest driver from your GPU manufacturer’s site (NVIDIA, AMD, Intel). For most integrated graphics, run Windows Update — it often includes audio driver patches.

When Monitor Speakers Aren’t Enough
Built‑in monitor speakers are convenient, but they rarely match the quality of dedicated desktop speakers or headphones. If you find the audio flat or too quiet for gaming or video calls, consider adding external speakers. They’ll connect via the 3.5 mm audio out on your monitor or directly to your PC.
Even with external speakers, you may still want to keep the monitor as the default device for system sounds while routing media to your speakers. Windows lets you set per‑app audio output — right‑click the speaker icon, go to Volume mixer, and assign different apps to different devices.
Frequently Asked Questions
How do I enable monitor speakers in Windows?
Open Sound settings, locate your monitor in the Playback tab, enable it (if greyed out), and set it as the default device. Then adjust volume in Properties.
Why can’t I hear sound from my monitor speakers?
The most common reasons: the monitor is not set as the default playback device, the cable doesn’t carry audio (DVI/VGA), or the monitor’s own volume is muted. Double‑check all three.
Can I use monitor speakers without external speakers?
Yes — that’s the whole point. As long as your monitor has built‑in speakers and the correct cable (HDMI, DisplayPort, or USB‑C), you don’t need any extra hardware.
How to fix no sound from monitor speakers?
Update audio drivers in Device Manager, verify cable connections, enable the device in the Playback tab, and test with the Windows troubleshooter.
Conclusion
