The LG UltraGear 45GX950A-B is a 45-inch curved 5K2K OLED gaming monitor with dual modes: 5120 × 2160 at 165Hz for detailed ultrawide play or Full HD at 330Hz for fast-paced gaming. It suits gamers who want to switch between immersive high-resolution visuals and higher refresh rates.

Recommended For

  • PC gamers who alternate between immersive single-player, racing, or flight-simulation games at native 5K2K/165Hz and faster-paced games at 330Hz in the lower-resolution Dual Mode.
  • People who want one large screen for both PC gaming and wide-canvas work, such as keeping several windows visible alongside games, and are comfortable working with a strongly curved display.
  • Flight- and racing-simulation players who want a wide, curved OLED view and prioritize immersion over a conventional flat-screen layout.
  • Laptop users who want to connect video and charge a compatible computer through one USB-C cable, while using the monitor as a large gaming and work display.
