All told, this ultrawide monitor should feel fast, fluid, and visually striking. The 240Hz OLED panel gives motion superb clarity, while the 800R curve wraps the image around your field of view more than many ultrawide displays – improving immersion. HDR content benefits from OLED’s perfect blacks, and adaptive sync support helps keep gameplay smooth across both NVIDIA and AMD systems.
What we like about the LG UltraGear 39GX90SA-W
Immersive 39-inch ultrawide OLED panel
The LG 39GX90SA-W uses a 39-inch 3440 x 1440 OLED panel with a 21:9 aspect ratio and steep 800R curve, giving it a highly immersive feel for racing games, cinematic RPGs, simulators, and wide-field competitive titles. The expanded horizontal space also makes it useful for multitasking, timeline editing, and productivity.
240Hz refresh rate with OLED response
The combination of a 240Hz refresh rate and 0.03ms response time makes this monitor exceptionally fast. OLED pixel response helps reduce smearing and ghosting, while the high refresh rate gives fast-paced games a smoother, more responsive feel. NVIDIA G-Sync compatibility and AMD FreeSync Premium further help reduce tearing and stutter.
Strong HDR and color performance
With OLED contrast, a claimed 1,500,000:1 contrast ratio, up to 98.5% DCI-P3 coverage, and VESA DisplayHDR True Black 400, the 39GX90SA-W is built for deep blacks, rich color, and strong highlight detail. It should be especially effective in darker games, HDR films, and visually rich single-player titles.
Built-in webOS adds extra flexibility
Unlike a traditional gaming monitor, this model includes LG’s webOS platform, giving access to streaming apps and cloud gaming services without needing a PC or console switched on. That makes it a more versatile entertainment display, particularly for users who want one screen for gaming, movies, and casual streaming.
Who should buy this ultrawide OLED gaming monitor
The LG 39GX90SA-W is best suited to gamers who want an immersive ultrawide OLED experience rather than a standard 27-inch esports screen. It is especially appealing for players of racing games, open-world titles, flight sims, and cinematic single-player games, while still offering enough speed for competitive play.
