UltraWide display offers more space
The curved 34" VA display with a resolution of 3440 × 1440px and a 21:9 aspect ratio provides a wide workspace suitable for multitasking, content creation and multimedia entertainment. The 1800R curvature brings the edges of the screen closer to your natural field of view, helping to create a more impressive experience when watching films or gaming. The VA panel offers a typical contrast ratio of 3,000:1, a typical brightness of 300 nits and wide 178° viewing angles.
144Hz for smoother motion
The up to 144Hz refresh rate ensures smoother motion during daily work, content browsing and gaming. The monitor supports AMD FreeSync and VRR, which help to synchronise frames and reduce unwanted screen tearing. The gaming features are complemented by Dynamic Action Sync, Black Stabilizer, Crosshair and an FPS counter.
HDR10 Pro and 99% sRGB for balanced colours
HDR10 Pro technology helps to enhance detail in bright and dark areas of the picture and supports greater visual depth when watching content via webOS. The display offers a typical 99% coverage of the sRGB colour space and can display up to 1.07 billion colours, contributing to finer colour transitions and consistent colour reproduction.
AI Picture Pro enhances the displayed content
AI Picture Pro technology optimises the picture according to the content being displayed. AI Super Upscaling analyses individual objects in the scene and helps improve their definition, while Dynamic Tone Mapping Pro adjusts the brightness and detail of individual parts of the image. The result is a cleaner and more balanced display when using content via webOS.
Automatic brightness according to ambient lighting
The Auto Brightness Control feature automatically adjusts the screen brightness according to the amount of light in the room. This means the monitor adapts the display to the current conditions without the need for frequent manual adjustments, ensuring comfortable use during the day and in the evening.
webOS 26 combines work and entertainment
The integrated webOS 26 system also allows you to use the LG Smart 34U640SB-W without a constantly connected computer. It provides access to supported streaming services, a web browser and other smart features, while also allowing you to use the monitor for home office tasks. Access to webOS network features requires an internet connection and an LG account.
Smart AI features of the webOS system
The webOS environment offers AI Search, AI Concierge, Generative AI, AI Picture Wizard and AI Voice ID. AI Concierge provides personalised content suggestions and related information, while Generative AI allows you to discover and create content directly through the Smart Monitor. AI Picture Wizard learns your preferred picture style, and AI Voice ID can recognise individual users by voice in compatible apps to offer them a personalised experience. Availability of individual features may vary by region, language and service.
Wireless sharing across devices
You can stream content to the monitor wirelessly via Google Cast, AirPlay 2 and Screen Share. Google Cast extends the streaming options from supported mobile devices, AirPlay 2 makes it easy to connect to Apple devices, and Screen Share allows mirroring from devices such as Android or Windows computers. Wi-Fi and Bluetooth are also included.
AI Sound Pro for a more impressive sound
AI Sound Pro technology intelligently adjusts the audio according to the content being played, creating a virtual 11.1.2-channel surround sound. AI Object Remastering separates dialogue, music and effects, and then adjusts each component to make voices clearer and the music and effects tracks stand out better. The monitor is equipped with built-in speakers, so you don't need to connect external sound for normal multimedia use.
Gaming Hub for console-free gaming
The Gaming Hub provides access to supported games and cloud gaming services directly through the webOS. The offerings include, for example, GeForce NOW and Amazon Luna, and also plan for Xbox Cloud Gaming support. Supported games can be launched without an external games console, with some services requiring a separate subscription and a compatible game controller. Availability may vary by country and service.
USB-C with Power Delivery up to 90W
The USB-C port handles video, data and power delivery to a connected device with up to 90W. This means you can connect a compatible laptop to the monitor and charge it at the same time with a single cable. Other devices can be connected via 2× HDMI and 2× USB 2.0, making it easy to create a tidy workstation with fewer cables.
Convenient control and privacy protection
The LG Smart 34U640SB-W supports the AI Magic Remote, which uses a motion sensor and scroll wheel to control the cursor like a wireless mouse and to use supported voice and AI functions. The AI Magic Remote is sold separately. The LG Shield security solution helps protect your personal data and network communications when using the monitor's smart features.
LG Switch and Quick Control for easier work
The LG Switch application allows you to organise windows, manage smart functions with the keyboard and mouse, and switch between your computer and the webOS environment using keyboard shortcuts. The Quick Control feature provides quick access to frequently used menus and settings directly within the webOS environment.
Height and tilt adjustment
The stand allows you to adjust the screen position with an 80mm height adjustment and a tilt from −5° to 15°. The monitor also supports mounting on a VESA 100 × 100mm standard bracket, so you can arrange your workspace to suit your needs.

Colour Gamut
Determines how accurately the monitor can display colours. sRGB is ideal for 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
The value, given in nits or cd/m², determines the brightness level of the monitor. A brightness of over 400 nits is key for HDR content and readability in sunlight, while standard office monitors are fine with values over 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
