Smart gaming monitor with webOS 26
You don't just have to use the LG UltraGear 34GX90SB-W as a display device connected to a computer. The webOS 26 system provides access to streaming services, LG Channels, and other smart features directly from the monitor. The Gaming Portal also provides access to supported cloud gaming services like GeForce NOW and Amazon Luna, so you can run compatible games even without a separate console or gaming PC.
α8 AI Processor Gen3 optimises both picture and sound
The powerful α8 AI Processor Gen3 continuously analyses the content being played and adjusts the picture and sound settings accordingly. AI Picture Pro uses AI Super Upscaling to enhance the quality of individual objects in the scene, and Dynamic Tone Mapping Pro optimises brightness and detail. The result is a clearer, more balanced picture when using content via webOS.
AI Sound Pro for more impressive surround sound
AI Sound Pro technology creates virtual 11.1.2-channel surround sound and adapts its character to the content currently playing. AI Object Remastering separates dialogue, music, and sound effects, then adjusts each component for better clarity and a more balanced delivery. The monitor has a pair of integrated 5W speakers.
UltraWide OLED with a dramatic 800R curve
The curved 34" OLED display with a 3440 × 1440 px resolution and a 21:9 aspect ratio provides a wide field of view and more space on the sides than a classic 16:9 display. The dramatic 800R curvature surrounds your field of view, enhancing the sense of immersion in racing, action, and other games. The OLED panel also delivers very deep blacks and a typical contrast ratio of up to 1,500,000:1.
Bright OLED picture with MLA+ technology
The OLED panel uses Micro Lens Array+ (MLA+) technology, which increases light efficiency and helps to achieve a peak brightness of up to 1300 nits. Support for VESA DisplayHDR 400 True Black, HDR10, and 98.5% coverage of the DCI-P3 colour space contributes to striking contrast, rich colours, and well-rendered dark scenes. The display can show 1.07 billion colours.
240Hz and 0.03ms response time for fast-paced gaming
A 240Hz refresh rate combined with an extremely fast 0.03ms GtG response time displays fast-paced action with high fluidity and minimal motion blur. NVIDIA G-SYNC Compatible, AMD FreeSync Premium Pro, and VESA AdaptiveSync technologies synchronise the refresh rate with the graphics card's output, helping to reduce screen tearing and stuttering.
Gaming features for better control of the action
The LG UltraGear also features Dynamic Action Sync to help reduce input lag, and Black Stabilizer for better visibility of detail in dark scenes. Crosshair adds a virtual crosshair to the centre of the screen, and the FPS Counter lets you monitor the current frame rate.
USB-C, HDMI 2.1 and DisplayPort
The monitor offers 2× HDMI 2.1, DisplayPort 1.4 with DSC and USB-C, so you can easily connect it to your gaming or work setup. The USB-C port supports data transfer and can power a compatible laptop with up to 65W. There are also two USB 2.0 ports, a LAN connector and a headphone output. WQHD picture at 240Hz can be achieved via DisplayPort 1.4 or HDMI 2.1.
Slim stand and four-sided borderless design
The four-sided, virtually borderless design is complemented by a space-saving L-shaped stand and Unity Hexagon Lighting RGB backlighting on the rear. The stand allows you to adjust the height, tilt and swivel of the display. VESA 100 × 100mm standard is available for mounting the monitor on a bracket.

Colour gamut
Determines how accurately the monitor can display colours. sRGB is ideal for web, films or games. Graphic designers or professionals will appreciate DCI-P3/Adobe RGB. 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 picture 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
