LG UltraGear OLED GX9 45-inch Ultrawide Gaming Monitor
Product description
This 45-inch ultrawide OLED monitor from LG brings immersive curved visuals and rapid response for focused gaming and content creation. The WOLED panel with MLA+ technology yields deep blacks and vivid colours, helping scenes appear more natural while keeping motion crisp for fast-paced play.
Key Points
The monitor targets gamers who prioritise fluidity and image quality. With a 3440 x 1440 WQHD ultrawide resolution it offers more horizontal screen space for simulation titles, RPGs and productivity across multiple windows. The curved 45-inch format enhances immersion and reduces peripheral distortion during long sessions. 🎮
Colours are close to developer intent thanks to a wide DCI-P3 coverage and DisplayHDR True Black 400, which emphasises both bright highlights and inky blacks. Support for variable refresh technologies like G-SYNC and FreeSync Premium Pro means fewer tears and smoother frame pacing with compatible GPUs. For competitive players, features designed to improve motion clarity are part of the experience. ⚡
Benefits
Low latency and high refresh deliver a responsive feel in fast games and simulations. The 240Hz panel frequency, combined with a very short grey-to-grey measurement, reduces perceived blur and improves target tracking in action scenes. Connectivity is versatile, with DisplayPort 1.4, HDMI 2.1 and USB-C enabling high-bandwidth inputs from modern consoles and PCs. For those who also stream or create content, the ultrawide aspect gives more room for timelines and chat windows without needing a second display. 🎯
Consider that OLED panels may exhibit different ageing characteristics compared with LCDs, according to the manufacturer, and extreme static imagery over very long periods can increase burn-in risk. Also, the peak brightness is optimised for contrast rather than sustained extreme luminance.

Usage Recommendations
Place the monitor at a comfortable viewing distance to make the most of the curved ultrawide field and reduce eye movement across the screen. For competitive gaming enable the variable refresh option in your GPU control panel to match frame output with the 240Hz refresh. When using the monitor for colour-sensitive editing check calibration with a hardware colourimeter, as the wide DCI-P3 gamut will otherwise differ from sRGB-centric workflows. Also, use dynamic content and avoid prolonged static elements to minimise potential OLED retention effects.
