LG UltraGear evo GX9 Review: Tandem OLED Shines in This Brutalist Gaming Monitor

October 25, 2026 - 22:12

The LG UltraGear evo GX9 is a costly but impressive dual-mode ultrawide gaming monitor. Its image quality ranks among the best we have seen, largely because of the new RGB tandem QD-OLED panel technology inside it.

The display is built for players who want both high resolution and high refresh rates without choosing between them. Its dual-mode design lets users switch between a sharp, detail-rich mode for slower, story-driven games and a faster mode for competitive play. That flexibility is rare in this category and gives the monitor a clear reason to exist beyond its striking looks.

The tandem QD-OLED panel is the real story. It delivers deep blacks, strong contrast and vivid colors that hold up across bright and dark scenes. The RGB tandem structure also helps push brightness higher than earlier OLED designs while keeping color accuracy steady. In practice, games look rich and clean, with fine details visible in shadows and highlights alike.

The monitor's design leans into a brutalist style, with hard lines and a heavy industrial feel. It is not subtle, but it feels purposeful and well built. The stand is sturdy, and the overall construction suggests this is a piece of hardware meant to last.

The main drawback is price. This is not a budget option, and buyers will pay a premium for the panel technology and dual-mode feature set. Still, for those who want one of the best images available in an ultrawide gaming monitor, the GX9 makes a strong case. It is a specialized, expensive display that delivers on its promises.
