Overview

The LG 24LM520S-WU runs a 24-inch HD (1366×768) IPS-type panel at 16:9 aspect ratio, paired with LG's WebOS 3.5 smart TV platform. At this screen size and resolution, pixel density lands around 65 PPI — adequate for lean-back TV viewing from a few feet away, but below the threshold where text and UI elements look crisp at a typical monitor distance of 18–24 inches. The wide viewing angle panel is the genuinely useful spec here: image consistency holds whether multiple people are watching from different angles or the display is mounted in an unconventional position. Built-in Wi-Fi and dual 5W stereo speakers make it a self-contained entertainment unit that requires nothing but power and a network connection out of the box.

This display targets users who need a single screen to serve multiple roles — a student who wants a TV for the dorm and a monitor for the laptop, or a guest room that doubles as an office. WebOS 3.5 handles the core streaming use cases (Netflix, YouTube, Prime Video) without friction, though its 2016-era platform means anyone chasing newer apps or services may find gaps. As a PC monitor, the HD resolution is a notable constraint for productivity work — but for email, light web browsing, or a secondary display for reference material, it's functional. The 5W speakers punch at their weight class: clear enough for dialogue, modest for music, and not a replacement for even a basic soundbar in a real entertainment setup.

Pros & Cons

👍 Pros

Dual-function design as both smart TV and PC monitor eliminates the need for two separate displays in space-constrained setups.
WebOS 3.5 provides a polished, remote-friendly smart TV interface with built-in streaming app access — no external media player required.
Built-in Wi-Fi enables wireless streaming and screen mirroring from smartphones without additional hardware.
Wide viewing angle IPS-type panel delivers consistent image quality across horizontal and vertical angles, useful for shared viewing.
Dual 5W stereo speakers provide usable audio output without an external sound system for everyday content.

👎 Cons

HD (1366×768) resolution is below Full HD — fine for casual TV viewing at this screen size, but noticeably soft for PC text work or productivity tasks.
WebOS 3.5 is a legacy platform from 2016 and no longer receives feature updates, meaning app availability and compatibility with newer streaming services is increasingly limited.
At 24" with HD resolution, pixel density is low enough that text rendering at normal desk distances appears softer than a comparable 1080p monitor.
No indication of HDMI 2.0 or high refresh rate support — unsuitable as a gaming monitor where frame rate and input lag matter.

Frequently Asked Questions

Can the LG 24LM520S-WU function as a PC monitor as well as a TV?

Yes — this is a core design intent of this unit. It accepts HDMI input for use as a standard external display while also operating as a standalone smart TV via WebOS 3.5. Switching between sources uses the remote or input selector. Resolution is 1366×768 (HD), so as a PC monitor it's fine for general use but not ideal for high-density text work.

What streaming services are available through WebOS 3.5?

WebOS 3.5 supports major platforms including Netflix, YouTube, Amazon Prime Video, and Hulu through its launcher. Note that WebOS 3.5 is a 2016-era platform — some newer apps may not be available or may have limited functionality compared to current smart TV operating systems.

How does the built-in Wi-Fi perform for streaming?

Built-in Wi-Fi enables direct connection to your home network for streaming without a media stick or external device. Bandwidth requirements for HD streaming are modest (5–10Mbps), well within reach of typical home Wi-Fi, and the LG's wireless radio handles this reliably.

Are the 5-watt speakers adequate for a room environment?

The dual 5W speakers provide stereo output suitable for a desktop or small bedroom setup. At this wattage, they produce acceptable dialogue clarity and music reproduction at moderate volume — but they won't fill a living room or deliver impactful bass. For serious audio, an external speaker or soundbar via HDMI ARC or headphone out is recommended.

What is the maximum resolution this display supports?

The 24LM520S-WU's native resolution is HD (1366×768). It will accept higher-resolution signals from connected sources but will downscale them to fit. Users expecting 1080p or 4K output should look at alternative models.
