Curved UltraWide® Display With G-SYNC™

  • The 34UC89G combines an immersive IPS Curved UltraWide screen with NVIDIA G-SYNC compatibility, a 144Hz refresh rate, plus a dedicated Game Mode and Black stabilizer for ultimate domination.

NVIDIA G-SYNC™ Compatible

  • This monitor supports NVIDIA G-SYNC* , an advanced display technology that synchronizes refresh rates to the GPU inside GeForce GTX-powered PCs, eliminating screen tearing and minimizing stutter and input lag for a smoother, faster gaming experience.

144Hz Refresh Rate

  • Games played on the LG 34UC89G are noticeably smoother and clearer when compared to game play on monitors with refresh rates of 60Hz or 75Hz. Combine the clarity and smooth action with the curved screen, and gamers will fall in love with an optimized and immersive gaming experience.

UltraWide For A Gaming Advantage

  • The graceful curve of the screen offers an immersive gaming experience. The wider displays allows enhanced game play with the ability to see more of the gam than on a 16:9 monitor.


  • With the Crosshair feature, gamers can take their skills to the next level. By placing the striking point in the center of the display, the feature enhances firing accuracy in first-person shooter games.

Advanced Gaming Features

  • Serious gaming features for serious gamers. Quickly optimize monitor settings to activate Black Stabilizer to reveal superior detail in dark scenes while the Dynamic Action Sync feature assures smooth, fluid gaming action.

21:9 Supported Games

  • With the increase of demand for 21:9 monitors, more game publishers are designing games to support the more immersive 21:9 aspect ratio experience.

OnScreen Control

  • Watch how OnScreen Control puts a host of essential monitor settings into a handy window for quick, easy access. Volume, brightness, picture mode presets, Screen Split 2.0 and more can now be adjusted with just a few clicks of the mouse, instead of hard buttons on the monitor.
