The LG 27US500-W.AUS is a 27-inch 4K UHD monitor designed to deliver sharp, detailed visuals with accurate color for digital imagery work. It targets creative professionals and multimedia users who need a high-resolution display with features like HDR10 support and a wide color gamut, all housed in a borderless, white design. While it offers impressive picture quality and user-friendly software controls, its stand provides limited adjustability and it lacks built-in audio, making it a strong choice for visual tasks but less ideal for those needing extensive ergonomic customization or integrated sound.
This monitor’s bottom line is clear: it prioritizes visual fidelity and software-driven convenience over physical flexibility, making it a solid pick for stationary, color-sensitive workstations where the primary focus is on the screen’s output rather than its adjustability or multimedia features.

Design and Build
The LG 27US500-W.AUS sports a clean, modern aesthetic with a white finish and a borderless design on three sides, which helps maximize the screen real estate and reduces visual distraction when used in multi-monitor setups. The overall build quality aligns with LG’s reputation for reliable consumer displays. The stand, while described as ergonomic, offers tilt adjustment as its sole physical customization option. This means users cannot adjust the height, swivel the screen side-to-side, or pivot it into a portrait orientation without a third-party monitor arm. The monitor is VESA mount compatible, providing a path to greater flexibility for those willing to invest in a separate mounting solution.
The screen features a matte finish, which is effective at minimizing glare and reflections from ambient lighting, a practical choice for office or studio environments. From a connectivity perspective, the ports are conveniently located for access. The packaging includes the necessary stand components, screws, a power adapter, and an HDMI cable, allowing for a straightforward out-of-the-box setup for a basic single-cable connection.
Performance and Features
Visual Performance
The core appeal of the LG 27US500-W.AUS lies in its 4K UHD IPS panel. The 3840 x 2160 resolution on a 27-inch screen delivers a high pixel density, resulting in exceptionally sharp text and detailed imagery that benefits creative professionals working with digital assets. LG emphasizes a 1000:1 contrast ratio, which it states provides deeper blacks than conventional IPS panels, contributing to more lifelike visuals. With a brightness of 300 cd/m² and support for HDR10 content, the monitor is capable of handling a dynamic range suitable for multimedia consumption and content creation that utilizes HDR metadata.
A key performance specification is the wide color gamut, covering up to 90% of the DCI-P3 spectrum. This elevated color expression is crucial for tasks requiring color accuracy, such as photo editing, video work, and design, ensuring colors appear vibrant and true-to-source. The IPS technology ensures consistent color and contrast across wide 178-degree viewing angles, which is essential for collaborative reviews or when viewing the screen from off-center positions.
Connectivity and Ports
The monitor provides standard connectivity options for a display in its class. It includes two HDMI ports and one DisplayPort, offering flexibility to connect multiple source devices like a desktop PC and a gaming console or media streamer simultaneously. The inclusion of an HDMI cable in the box is a welcome convenience for immediate setup. Notably, the specification data lists Adaptive Sync technology, specifically FreeSync, which can help reduce screen tearing during video playback or less demanding gaming, though the 60Hz refresh rate limits its utility for high-frame-rate competitive gaming.
Key Features and Software
LG differentiates this monitor with its OnScreen Control software. This feature allows users to adjust monitor settings, split the screen into customizable layouts for multitasking, and manage basic options directly from their computer with mouse clicks, bypassing the traditional on-screen display (OSD) buttons. This can significantly streamline workflow efficiency. For user comfort, the monitor incorporates Flicker Safe technology to reduce screen flicker and a Reader Mode designed to minimize blue light emission, both aimed at reducing eye strain during long work sessions.
Setup, Support and Ownership
Setting up the LG 27US500-W.AUS is a simple process. The stand assembles quickly with the provided screws, and connecting a source via the included HDMI cable is straightforward. For those seeking more advanced ergonomics, the VESA mount compatibility (100x100mm) allows for installation on a wide range of monitor arms or wall mounts, which would address the limitation of the tilt-only stand. The monitor does not have built-in speakers, so users will need to rely on external speakers or headphones for audio playback.
LG provides a standard one-year warranty for parts and labor. Support resources, including driver and software downloads like the required OnScreen Control application, are available through LG’s official support website. As with many modern monitors, long-term ownership is generally maintenance-free, with performance reliant on the inherent quality of the panel and its components.
What Owners Say
Overall feedback from users is positive, reflected in the strong average rating. The majority of reviews are highly favorable, with praise frequently directed at the monitor’s 4K clarity, color accuracy, and the value it offers for the price. A significant portion of users appreciate the sharp image quality for both work and media consumption. Critical feedback tends to focus on the limitations of the stand, specifically the lack of height and swivel adjustments. Some users have noted the absence of built-in speakers as a minor inconvenience. The general consensus confirms that it performs well for its intended use cases, particularly for office work, content creation, and general home computing.

- User-friendly OnScreen Control software for easy adjustments
- Borderless design maximizes screen space
- Includes HDMI cable and power adapter in the box
- Matte screen finish minimizes reflections
- Flicker-safe and reader mode for reduced eye strain

Who Should Buy It (and Who Should Skip It)
The LG 27US500-W.AUS is an ideal choice for creative professionals, graphic designers, photo editors, and anyone whose work benefits from high-resolution, color-accurate displays. It’s also well-suited for general multimedia users and office workers who prioritize screen clarity for documents and spreadsheets and appreciate software-based control conveniences. Users looking for a clean, borderless monitor for a multi-display setup will find its design appealing, especially if they plan to use VESA mounts.
This monitor is not the best fit for competitive gamers who require high refresh rates, as its 60Hz panel is geared towards visual fidelity over speed. Users who need extensive physical adjustability directly from the stand, such as height and swivel, should look for models with more ergonomic options or be prepared to purchase a separate arm. Those who rely on monitor speakers for audio should also consider other options or factor in the cost of external speakers.

Final Verdict
The LG 27US500-W.AUS successfully delivers on its primary promise: providing a high-quality 4K visual experience with strong color performance at a compelling value point. Its strengths in resolution, color gamut coverage, and innovative software controls like OnScreen Control make it a productivity-focused display that can enhance workflows for creators and professionals. The inclusion of comfort features like flicker reduction and a matte anti-glare screen further solidifies its position as a thoughtful tool for extended use.
However, its compromises are clear and largely physical. The tilt-only stand feels restrictive in a market where height and swivel adjustments are increasingly common, pushing users toward VESA solutions for true ergonomic comfort. The lack of built-in speakers is a minor but notable omission for a full multimedia experience. Ultimately, if your priority is outstanding image quality for static or creative content and you can work within its ergonomic and audio limitations, the LG 27US500-W.AUS represents a very capable choice.

FAQs
Does the LG 27US500-W.AUS have speakers?
No, the LG 27US500-W.AUS does not have built-in speakers. Users will need to provide their own audio solution, such as external desktop speakers, a soundbar, or headphones connected directly to their computer or other audio source device.
Can the monitor height be adjusted?
The included stand only allows for tilt adjustment. It does not offer height adjustment, swivel (side-to-side rotation), or pivot (portrait orientation) capabilities. For these adjustments, the monitor is VESA mount compatible (100x100mm), allowing it to be attached to a third-party monitor arm or stand that provides the desired ergonomic flexibility.
What is OnScreen Control and is it required?
OnScreen Control is a software utility from LG that lets you adjust monitor settings and split your screen into multiple window layouts using your mouse and computer, rather than the physical buttons on the monitor. It is not required for basic operation, but it is required to access those specific software-based customization features. The application must be downloaded and installed from LG’s support website.
Is this monitor good for gaming?
The LG 27US500-W.AUS is suitable for casual gaming and single-player experiences where visual quality is paramount, thanks to its 4K resolution and HDR10 support. However, its 60Hz refresh rate and 5ms response time make it less ideal for fast-paced, competitive gaming where higher refresh rates (e.g., 144Hz or 240Hz) are preferred for smoother motion. It does support Adaptive Sync (FreeSync) which can help reduce screen tearing.
