LG 39GX90SA-W 39-inch Ultragear WQHD (3440×1440) OLED Curved Gaming Monitor
In actual use, the OLED monitor panel and 240Hz refresh rate should combine to produce a display that feels both visually rich and very fast – with the OLED response time being unbeatable. The ultrawide format can improve immersion significantly in supported titles, while the OLED panel gives dark scenes and HDR content more depth than typical LCD alternatives. The smart TV-style features also make it more flexible outside traditional PC gaming than most high-end monitors.
What we like about this LG UltraGear OLED Curved gaming monitor
Huge 39-inch OLED ultrawide creates a very immersive gaming setup
A 39-inch 21:9 OLED panel already makes this monitor feel more dramatic than a standard 27-inch display, and the 800R curve pushes that sense of immersion even further. It is clearly aimed at users who want to feel surrounded by the game rather than simply looking at a screen.

240Hz refresh rate and 0.03ms response give it genuine speed
This is not just a cinematic ultrawide. The 240Hz refresh rate and near-instant OLED response time give it real competitive performance credentials, helping fast movement look clearer and making the display feel more responsive in games where timing matters.
OLED contrast and strong color coverage make it visually rich
OLED remains one of the most attractive panel technologies for gaming because of its deep blacks and high perceived contrast. Combined with up to 98.5% DCI-P3 coverage and True Black 400 support, this monitor should look striking in both HDR-capable games and media.
webOS adds standalone streaming and cloud gaming utility
The inclusion of webOS gives the monitor a more unusual role than most gaming displays. It can act as a screen for streaming apps and cloud gaming services even without a PC attached, which adds flexibility for users who want an entertainment display as well as a gaming monitor.
800R curve is aggressive in a way that suits the format
On a screen this wide, the steep 800R curvature is not just a gimmick. It helps keep the edges of the display in your field of view and makes the ultrawide experience feel more cohesive, especially in cockpit games, racing, and first-person titles.
Who’s this OLED gaming monitor for?
This monitor is best suited to gamers who want a very immersive ultrawide OLED display with high refresh performance, and to users who like the idea of combining gaming and built-in streaming in one large premium screen.
