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.
