LG OnScreen Control

LG OnScreen Control is a free desktop utility for arranging windows and managing selected settings on compatible LG monitors. It is best suited to LG monitor owners who want those controls alongside screen-layout tools, though model and connection requirements narrow its appeal.

Overview

The app combines workspace layout tools with monitor adjustments and firmware updates. That is a useful mix if you already have a supported LG display: Screen Split helps organize windows, while picture and game settings are accessible from the PC. It is not a universal monitor-control solution, and relying on the wrong display mode or an unsuitable connection can block key functions.

Key features

Screen layout and picture presets

Screen Split divides the monitor into regions to suit a work environment, giving users a way to arrange a display around recurring tasks. My application Preset changes the picture mode to a selected preset when a user clicks a particular application window, which is useful when different apps call for different monitor modes. 5:9 Preview lets users preview an application in a 5:9 area and move it to a chosen position; it is a specialized preview tool rather than a general window-management feature.

Monitor and gaming controls

Users can adjust brightness, contrast, and other monitor settings, as well as game-related settings. These controls require a USB connection between the PC and monitor. A non-genuine cable or adapter can prevent DDC/CI communication, and using a third-party monitor may limit some features, so the app is most dependable as a companion for supported LG hardware.

Firmware updates

OnScreen Control can update monitor firmware when the PC has internet access and is connected to the monitor using a supported USB cable. This puts updates alongside the other monitor tools, but the connection and internet requirements make it a conditional convenience rather than a cable-free maintenance option.

Pricing

OnScreen Control costs nothing. The free download includes access to the app for supported monitor models on Windows or macOS; there is no paid tier or free trial to weigh against it. Its main cost is compatibility: the free plan is useful only if the monitor model is supported, and LG advises checking the owner’s manual.

Platforms

LG provides installers for Windows and macOS. The app does not support the PC’s Duplicate display setting; if its menu does not appear, LG advises switching to Extend mode. Monitor settings and firmware updates also require the specified USB connection, while firmware updates need internet access.

Who it's for

Choose it if you use a supported LG monitor and want screen regions, application-triggered picture presets, game settings, or PC-based access to monitor controls. It is a weaker fit if you need one utility to work across monitor brands, if your model is unsupported, or if your setup depends on Duplicate display mode. LG’s U.S. monitor support page offers 24/7 chat support, video tutorials, and phone, chat, or email contact options.

Pros and cons

• Pros: Screen Split, monitor controls, game settings, and firmware updates bring several monitor tasks into one free utility.
• Pros: My application Preset can switch picture mode when a chosen app window is clicked, avoiding manual mode changes for that workflow.
• Cons: Availability is limited to certain LG monitor models, so the app is not a safe choice before checking model support.
• Cons: USB connection requirements for settings and firmware, plus the Duplicate-mode restriction, can make it unsuitable for some desk setups.
• Cons: Third-party displays and non-genuine cables or adapters can limit features or disrupt DDC/CI communication.

Alternatives

For a broader shortlist, browse Monitor Control Software or Color Management Software.

• Monitor Switch is a free option for API, Linux, self-hosted, or web environments, but it is usable and not yet released and requires a Raspberry Pi.
• AOC G-Menu is another free Windows utility for supported AOC devices, making it the more relevant pick for those displays.
• ASUS DisplayWidget Center is free for compatible ASUS monitors and runs on Windows and macOS, so it suits users with that hardware instead.
• ddcutil is a free GPLv2 option for Linux, API, or self-hosted use.
• Lunar offers a free version on macOS, with a free trial also available.
• Monitor Brightness Control is a free Linux tool for DDC/CI-compatible monitors with I2C access.
• Twinkle Tray is a free Windows 10 and Windows 11 option for most laptops and DDC/CI-enabled monitors.
• ClickMonitorDDC is free for personal use on Windows.

Verdict

LG OnScreen Control is a sensible free choice for owners of a supported LG monitor who want desktop layout tools and selected monitor controls together. Its combination of Screen Split, picture presets, game settings, and firmware updating is the main reason to choose it. Look elsewhere if your display is unsupported, you need Duplicate mode, or you want a utility intended to serve monitors across brands.
