The Fast VA 1500R curved panel delivers immersive visuals, while HDR400 enhances color and contrast. Equipped with an ergonomic stand, USB hub, and G-Menu software for customizable settings, this monitor is designed for gamers who demand precision and comfort.

What's new compared to the AOC CU34G2XP

  • Refresh Rate: Significant upgrade from 180Hz to 240Hz, offering top smoothness for the ultrawide category.

  • Response Time: Improvement in Gray-to-Gray (GTG) reaching 0.5ms (compared to 1ms), drastically reducing ghosting.

  • Panel Quality: Use of a new VA panel with increased curvature and improved viewing angles for a more immersive experience.

  • HDR Performance: Upgraded brightness and HDR certification providing more vivid colors and intense contrast.

  • Design: New, more aerodynamic chassis in the G4 series with improved airflow and a sturdier support base.

WQHD Resolution

With a resolution of 3440 x 1440 Wide Quad HD (WQHD), it offers superior image quality and clear images that reveal every detail.

The 21:9 widescreen aspect ratio is ideal for watching movies in extended format or immersing yourself in the latest game, while providing more space when it's time to work.

VA Panel

1MS MPRT

MPRT is an acronym for Moving Picture Response Time. MPRT technology turns off and on your screen's backlight during image changes.

With the reduced time a frame appears on the screen, "ghosting" and "blurring" effects are minimized, resulting in a smoother, more "fluid" gaming experience.
