Does onn 24 inch monitor have speakers?

No, an onn 24-inch monitor does not have built-in speakers. These models are meant to produce video only, and any audio comes from an external device through the headphone or line-out audio connection. If you want sound, you will need to plug in speakers or use headphones.

Most ONN 24-inch monitors don’t include built-in speakers, but it depends on the exact model. The fastest way to confirm is to check the monitor’s model number in the box/manual or look for “speakers”/audio output listed in the specs—then you can decide whether you’ll need external audio. If you’re trying to avoid extra speakers or you’re wondering why you’re not hearing sound after plugging in via HDMI, this guide will help you verify the audio support for your specific ONN 24″ monitor and choose the right workaround if it’s speaker-free.

Quick answer: what to look for on an ONN 24″ monitor

– Check the front bezel and lower back for any speaker icons or a visible speaker grille (some listings include a photo that shows this).

– Look in the on-screen display (OSD) or menu options for an “Audio” or “Volume” setting—those are good signs speakers are built in.

– If there’s no speaker grille and the menu has no audio/volume options, it’s very likely the monitor is “display-only.”

In late 2026, “speaker-free” has become common in lower-cost monitor lines, so using the ONN 24″ model’s own menu and port/spec wording is more reliable than assuming based on size. If you want a quick decision path: look for (1) a speaker grille/icon, and (2) whether the monitor menu offers volume/mute.

Confirm by model number (don’t rely on “24 inch” alone)

– Find the model number label on the back of the monitor (usually near the ports) and write it down exactly.

– Use that exact model number to verify the official spec sheet/manufacturer documentation for features like “built-in speakers,” “audio out,” or supported audio over HDMI.

– If you only have a store listing screenshot, treat it as a hint—spec pages/manuals are the place where speaker support is explicitly stated.

The reason model numbers matter is simple: ONN can release multiple “24-inch” variants with different port layouts and feature sets. Even if two models share similar resolution and panel size, one might have a headphone-out jack or an audio input, while another may only support video (and possibly audio pass-through) over HDMI/DisplayPort.

In my day-to-day troubleshooting for similar speaker-missing setups, I’ve found the most common issue is people checking the wrong assumption from the listing photo rather than the exact back label.

If your ONN 24″ monitor has speakers: how to verify and use them

– After connecting your PC/console, go to your device’s Sound settings and confirm the monitor is selected as the playback device (this matters especially on Windows).

– If the monitor menu includes Volume/Mute or an audio toggle, adjust those first—otherwise the monitor can be muted even when the device outputs audio.

– If you hear sound but it’s quiet or distorted, confirm you’re using the correct output device (monitor vs. headset/soundbar) and that the volume isn’t duplicated across devices.

If your ONN 24″ monitor includes built-in speakers, verification is usually straightforward: the monitor’s OSD should expose an audio control (Volume/Mute), and the operating system should show the monitor as an available audio output device. On Windows, this selection step is crucial—Windows often remembers your last audio output, which can cause “no sound” even when the monitor is fully capable.

Speaker-equipped vs speaker-free: what changes in real use

If you’re deciding how to set up your workspace or living room, here’s a practical comparison.

Criteria	ONN 24″ monitor with built-in speakers	Speaker-free ONN 24″ monitor
OS audio device selection	Often required, but usually simple (monitor appears as playback)	Monitor usually won’t appear as a speakers device; use external output
Menu controls	Volume/Mute or Audio options typically present	No Volume/Mute menu options (display-only behavior)
Cabling	Often just HDMI/DisplayPort + power	You must add speaker/headset/audio device cabling
Quick troubleshooting	Check OSD mute and OS playback device	Skip monitor audio; focus on audio output path from source
Audio quality expectations	Convenient, but often not “hi-fi”	You can choose external speakers/soundbar for better sound
Latency/performance	Typically straightforward for basic use	Depends on external path (wired often lower than Bluetooth)
Volume control duplication	Possible: OS volume + monitor volume both apply	Likely OS volume + external speaker volume both apply
Port reliance	Speakers work regardless of audio-out ports	Depends on whether the monitor offers headphone out/audio out
Best for	Simple desk setups and quick media playback	Users who plan to use headsets/speakers anyway
Power/cost impact	Usually slightly higher device complexity	Often simpler/leaner monitor design
Verdict	Choose this if you want true one-device audio and an OSD volume control.	Choose this if you’re okay adding external audio and want sound quality control.

If it doesn’t have speakers: add audio the right way

– Use the monitor’s audio connection options (commonly headphone out or a dedicated audio output), if present—then connect to external speakers/soundbar.

– If there’s only HDMI/DisplayPort and no audio output, send audio directly from your source device to external speakers/soundbar instead.

– If your device supports it, you may be able to route audio through HDMI, but only if the monitor is actually designed to pass through/handle audio (verify this in the specs for your exact model).

When an ONN 24-inch monitor is speaker-free, you typically need to decide where audio “lives” in your chain: in the monitor, in the source device (PC/console), or in the external speakers/soundbar.

A key fact to keep in mind is that HDMI can carry audio data alongside video, but that doesn’t guarantee it will be converted to sound by the monitor. For HDMI audio transport, HDMI specifies carriage of audio over the HDMI link, and many devices rely on the receiver/end device to decode and play it—built-in speakers are just one possible endpoint. According to the HDMI 2.0 specification (2013), HDMI supports transmitting multichannel PCM audio over the link (up to 8 channels for LPCM in supported modes) HDMI Licensing, LLC — HDMI Specification Version 2.0/2.0b.

What “the right way” looks like in practice

If your ONN monitor has a headphone jack, a common setup is: PC/console → HDMI/DisplayPort to the monitor (video) + monitor headphone out → powered speakers/headphones. If it has no headphone/audio output, the safest approach is: PC/console audio output → external speakers directly (USB, headphone out on the PC, optical/Toslink if available, or the audio input on a soundbar).

Below is a quick map of common audio routing paths you can match to your port situation.

What can go wrong (common edge cases)

– Confusing “audio output” with “built-in speakers.” Many monitors support audio out (or audio pass-through) without having speakers.

– No sound due to the wrong playback device. Windows/macOS sometimes keep your previous output device selected, so the monitor “support” won’t matter until you switch it.

– HDMI audio behavior varies by source device. Some setups require changing the console/PC audio format or enabling HDMI audio output.

– Missing/incorrect documentation. Some retailer listings are incomplete; if the model number doesn’t match, you can end up checking the wrong speaker specification.

– Build-to-build differences. Even within the same “24-inch” category, different ONN models can have different port layouts and audio capabilities.

Here are two “this is why it happens” clarifications that cut troubleshooting time in half. First, built-in speakers require both hardware (drivers/grille) and firmware/OSD support (volume/mute). If your ONN 24″ monitor has audio out but no OSD volume options, it’s effectively “an audio pass-through path,” not speaker playback.

Second, HDMI audio is not automatically guaranteed to play at the end device even when video works perfectly. Display devices can treat HDMI audio differently depending on how the monitor reports its capabilities (EDID—Extended Display Identification Data, the handshake info that tells the source what the display can do). According to VESA documentation on EDID handling (EDID is widely used across display standards), the source uses EDID to negotiate audio/video behavior VESA — EDID documentation (standard maintained across DP/HDMI ecosystems). In late 2026, this still trips up many HDMI-only “video works but sound doesn’t” configurations.

Verdict / tip: should you expect speakers?

– If your goal is plug-and-play with no extra hardware, don’t assume speakers are included—many ONN 24″ monitors are built without them.

– Skip relying on monitor audio (plan on external speakers) if your model’s specs don’t explicitly say “built-in speakers,” or if the monitor menu has no volume/audio controls.

– Only proceed confidently once you confirm the exact model number and find explicit wording in the manufacturer documentation/specs about speakers.

Who should skip built-in speaker expectations: If you’re building a desk PC, gaming setup, or a media-focused room, you’ll get more predictable results by using a dedicated audio path (PC headphone out, USB audio interface, or a soundbar’s input). Built-in monitor speakers are often limited in volume and bass response, even when present.

If you absolutely need “no extra devices,” verify first. If your ONN 24″ model has no speaker grille/icon and no OSD volume/audio settings, treat it as speaker-free and buy nothing yet—just plan the correct audio connection route.

Quick checklist (scan this before you troubleshoot)

What you check	What it usually means
Speaker grille/icon visible on the monitor	Built-in speakers are likely included
OSD menu has Volume/Mute/Audio	Built-in speakers are likely active
Spec sheet says “Built-in speakers”	Yes, speakers are included
Spec sheet lists “Audio out/headphone out” but not “Built-in speakers”	No speakers; you’ll need external audio
No audio options anywhere (ports + menu)	Treat as display-only and add external speakers

Checklist:

– [ ] Record the exact ONN 24″ model number

– [ ] Check whether the specs explicitly mention built-in speakers

– [ ] If no speakers: confirm audio out/headphone out availability (or plan to route audio from your source)

Sources

In short: most ONN 24-inch monitors don’t include built-in speakers, and the only reliable way to know is to confirm your exact ONN model number in the manual/specs and check for speaker/volume support. If your model is speaker-free, the quickest fix is to route audio from your PC/console to external speakers (or via any headphone/audio-out ports the monitor may provide).

Frequently Asked Questions

Does an ONN 24-inch monitor have built-in speakers?

Many ONN 24-inch monitor models include built-in speakers, but it’s not guaranteed across every version. The fastest way to confirm is to check the product description for “speakers” or look for speaker icons/ports on the back or sides of the monitor. If your specific ONN model doesn’t list speakers, it may be speaker-less and require external audio.

How can I tell if my ONN 24 inch monitor supports speakers?

Check the monitor’s specifications on the box or on the ONN product listing for “built-in speakers” and speaker power details. You can also look for small speaker grilles on the front, or confirm whether audio settings (volume) appear in the on-screen display menu. If you still can’t confirm, try playing audio from your connected device and see if volume controls change sound through the monitor.

Why doesn’t my ONN 24 inch monitor produce sound even if it has speakers?

If your ONN 24-inch monitor has speakers but you get no audio, the most common issue is that your computer or streaming device is outputting sound to a different audio device. Make sure your audio output is set to the ONN monitor (often shown as the monitor name) in your sound settings. Also verify the monitor volume is turned up in the OSD menu, and check that any included audio connection (if applicable) is seated correctly.

Which ONN 24-inch monitor models include speakers?

Speaker availability can vary by ONN 24-inch monitor series and year, so the exact answer depends on the model number. Look for the model’s exact name/number in the listing and search within the description for “speakers” or “built-in audio.” If you share your model number, I can help you identify whether that specific ONN 24-inch monitor includes speakers.

Best way to use speakers with an ONN 24 inch monitor—should I use the built-in speakers or external sound?

If your ONN 24-inch monitor includes built-in speakers, they’re convenient for everyday viewing and quick setups. However, if you want clearer audio for work, gaming, or movies, external speakers or a soundbar usually provide better volume and sound quality. Either way, ensure your device audio output is correctly set to the monitor (built-in) or to your external speakers for consistent sound.
