## Long description

The LG 39GX90SA-W is a 39" OLED monitor with a 3440 x 1440 Wide Quad HD resolution and a 21:9 aspect ratio. The curved OLED panel delivers deep contrast and wide 178° viewing angles, while built-in speakers and VESA mount compatibility support both multimedia and ergonomic installations.

Advantages
OLED panel technology provides high contrast and deep blacks with a typical contrast ratio of 1,500,000:1. The ultrawide 21:9 resolution increases horizontal screen space for multitasking and immersive content. A fast response time (0.03 ms) and a maximum refresh rate of 240 Hz reduce motion blur for fast-moving images. The curved screen and wide viewing angles preserve image quality across the display, and integrated speakers plus multiple video inputs (HDMI and DisplayPort) simplify connectivity.
Suitable for
Multitasking and productivity with wide 21:9 workspace
Content creation and color-critical previewing on OLED
Gaming that benefits from high refresh rate and low response time
Media playback and office use with built-in speakers

For gaming, select the higher refresh rate and ensure connected hardware supports the desired output. Use the headphone output or built-in speakers for audio playback.
Usage recommendations
To maintain image quality and maximize panel lifetime on an OLED display, avoid static high-contrast images for extended periods and use screen savers or power-saving modes when the monitor is idle. For best results in color-critical work, allow the panel to warm up and calibrate using appropriate tools.
