39-inch 800R Curved OLED Gaming Monitor

The LG UltraGear 39GX90SA-W combines a 39-inch WQHD OLED panel with an 800R curve, 240Hz refresh rate and 0.03ms response time. Built-in webOS provides direct access to streaming apps and cloud gaming services without a separate PC or console. The white cabinet includes a height-adjustable, swivel and tilt stand.

Suits Competitive and Immersive Gamers

Players who want ultra-fast motion clarity on a wide 21:9 curved OLED will benefit from the 240Hz panel and 0.03ms GtG response. FreeSync Premium and G-Sync Compatible support covers both AMD and NVIDIA GPUs. Buyers needing 4K resolution, higher typical brightness than 275 cd/m², or a flat screen should consider other models.

800R Curvature Defines the Viewing Experience

The 800R curve wraps the 3440 x 1440 panel tightly around the viewer’s field of vision, creating a more immersive feel than shallower curves or flat panels. This curvature radius is the key specification that determines whether the monitor matches the user’s preferred viewing distance and desk setup.
