27" IPS display with fine 4K UHD resolution
The LG Smart 27U731SB-W features a 27" IPS panel with a resolution of 3840 × 2160 px, providing a significantly sharper image and ample workspace for documents, spreadsheets, photo editing, and multimedia. The IPS technology delivers wide 178° viewing angles and consistent colour reproduction. The monitor achieves a typical brightness of 350 nits, a refresh rate of up to 60Hz, and a 5ms GtG response time in Faster mode.
HDR10 Pro and DCI-P3 90% for a richer picture
HDR10 Pro technology helps to enhance details in both bright and dark parts of the image and supports greater visual depth. The display also typically covers 90% of the DCI-P3 colour space and can display up to 1.07 billion colours, offering richer and finely graduated colour reproduction for photo editing, movie watching, and other multimedia uses. Additionally, the AI HDR Remastering feature can optimise the colour, brightness, and contrast of SDR content.
AI Picture Pro enhances the image in real time
Advanced AI Picture Pro processing optimises the overall image quality based on the content being displayed. The AI Super Upscaling feature analyses individual objects in the scene to help improve their definition, while Dynamic Tone Mapping Pro adjusts the brightness and detail of individual parts of the image. The result is a cleaner, more balanced picture when watching content through webOS. The model uses a platform with the α8 AI 4K Gen3 processor.
webOS 26 turns the monitor into a standalone entertainment hub
The integrated webOS 26 system allows the LG Smart 27U731SB-W to be used as a standalone smart device. It offers access to supported streaming services, a web browser, and cloud-based work applications. The Home Office environment lets you create and manage documents directly on the monitor, and the Remote PC feature provides remote access to a compatible computer running Windows 11 Pro or a newer system.
Automatic brightness based on ambient light
The Auto Brightness Control function automatically adjusts the screen's brightness to match the intensity of the surrounding light. This means the monitor can increase brightness during the day in a well-lit room and decrease it in the evening, promoting more comfortable viewing in various lighting conditions without the need for frequent manual adjustments.
Smart AI features of the webOS 26 system
The webOS 26 environment offers AI Concierge, AI Search, generative AI, AI Picture Wizard, and AI Voice ID. AI Concierge provides personalised content recommendations based on preferences and usage context, while generative AI allows you to search, discover, and create content, including images and music, directly on the Smart Monitor. AI Picture Wizard learns your preferred image style based on your choices and adjusts the settings accordingly, while AI Voice ID can recognise individual users' voices to offer them personalised recommendations. The availability of these features may vary by region, language, and supported services.
Wireless sharing from your phone and computer
You can stream content from compatible devices to the big screen without any cables. Google Cast makes it easy to send content from supported devices, AirPlay 2 is used for sharing from Apple devices, and Screen Share allows mirroring from Android or Windows, for example. Wi-Fi and Bluetooth are also available for connecting to a network and wireless peripherals.
USB-C with 65W Power Delivery for a Tidier Desk
The USB-C port allows you to transfer video at up to 4K at 60Hz, transfer data, and power a compatible laptop with up to 65W, all through a single cable. There are also 2× HDMI and 2× USB-A 2.0 ports, so you can easily integrate the monitor into your work or home setup with multiple devices.
Gaming Hub for Console-Free Gaming
The LG Smart 27U731SB-W also allows you to use cloud gaming services via the webOS system, without needing to connect a games console. The Gaming Hub offers access to supported services such as GeForce NOW and Amazon Luna, and LG has also announced upcoming support for Xbox Cloud Gaming. The availability of individual services and games may vary by country, and some may require a separate subscription and a compatible game controller.
Built-in Speakers and AI Sound Pro
A pair of built-in 2× 5W speakers allows you to use the monitor for films, TV series, music, and other multimedia content without needing to connect external speakers. AI Sound Pro technology intelligently adjusts the audio according to the content being played, creating virtual 11.1.2-channel surround sound. Furthermore, the AI Object Remastering feature separates dialogue, music, and sound effects, then adjusts them to make voices clearer and allow individual audio components to stand out.
Convenient Control and Security
The LG Smart 27U731SB-W supports the AI Magic Remote, which allows you to control the cursor with movement similar to a wireless mouse and provides quick access to supported voice and AI functions. The webOS environment is complemented by the LG Shield security solution, which helps protect your personal data and the security of the monitor's smart features. The availability of the AI Magic Remote in the box may vary by region.

Colour Coverage (Gamut)
Determines how accurately the monitor can display colours. sRGB is ideal for the web, films, or games. DCI-P3/Adobe RGB will be appreciated by graphic designers or professionals. The higher the value, the better the monitor displays colours.
Maximum Brightness
Given in nits or cd/m², this value determines the brightness of the monitor. A brightness above 400 nits is key for HDR content and readability in sunlight, while standard office monitors are fine with values above 250.
Refresh Rate and Response Time
The refresh rate (Hz) determines the number of frames displayed per second, so the higher the value, the smoother the image and the less eye strain. A lower response time (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
