Some LG 34-inch monitors have built-in speakers, but the screen size alone does not tell you whether yours does. Check the complete model number and the specification for your region. LG lists audio output rated 7 W × 2 for the UK versions of the 34WN650-W and 34WN750-B, and describes the US 34U530A-W as having built-in speakers. The available LG listings for the 34WN80C-B and 34WP500-B do not establish whether those models include speakers.
How to check whether your LG 34-inch monitor has speakers
Find the full model number, including its letter suffix, on the monitor label, in its on-screen information, or in the documentation that came with it. Then look up that exact model on LG’s product page or in its manual and check for a speaker or audio-output specification. Do not rely on “LG 34-inch” as a complete model description: features can vary by model and regional version.

For example, LG UK specifies 7 W × 2 audio output for the 34WN650-W and 34WN750-B. LG US describes the 34U530A-W as having built-in speakers, but the cited support listing does not state their wattage. These are examples, not proof that every LG monitor of this size has speakers.

Connecting a computer, console, or other source
For the 34WN650-W, LG UK lists two HDMI inputs and one DisplayPort input for video. Choose a cable or adapter only after checking which output your computer, console, or other source device provides and which input the exact monitor has. These ports are documented for this model; do not assume every LG 34-inch monitor has the same set.
The 34WN80C-B is identified as a USB-C monitor in LG’s US support listing, but that listing does not establish its complete port specification or the functions supported by USB-C. Check the product page or manual for your regional version before relying on USB-C for video or any other purpose.

Using external speakers or headphones
The 34WN650-W specification lists a headphone output, which provides a documented route for wired audio on that model. To connect external speakers, confirm that the monitor’s output and the speakers’ input are compatible. The cited specification does not establish a universal connection method for other LG 34-inch monitors, so check the exact model before buying a cable or adapter.

What to verify before choosing a monitor
- Confirm the full model number and regional version, rather than comparing monitors only by screen size.
- Look for an explicit built-in-speaker or audio-output specification; do not infer speaker presence from a model’s other features.
- Check the video inputs against the outputs on the device you plan to connect.
- If you want wired external audio, confirm that the monitor has an audio output and that it matches your headphones or speakers.
- Use the exact regional product page or manual when a support listing does not give complete specifications.
