LG 34GX90SA-W, 34″ OLED WQHD 3440×1440, 240 Hz, 0.03 ms, HDMI/DP/USB‑C, AMD FreeSync, HDR400

LG 34GX90SA‑W is a 34" ultra wide OLED monitor aimed at gaming and everyday use, with a serious emphasis on speed and contrast. The combination of 3440 x 1440 resolution, 21:9 format, and curved screen with 800R immerses you much more than a standard 16:9 panel. With a 240 Hz refresh rate and a response time of 0.03 ms, you get extremely smooth motion and minimal motion blur, especially useful in competitive shooters and racers. The OLED matrix with a typical contrast of 1500000:1 and brightness up to 1300 cd/m² provides very deep blacks and strong HDR effect, without the need for local dimming.

What you get

The wide 34" OLED panel with a resolution of 3440 x 1440 gives you more horizontal space for gaming, video editing, or working with several windows side by side, without a second monitor. The 800R curvature makes the image more natural for peripheral vision and reduces the need to “scan” with your eyes, especially in fast scenes. At 240 Hz and 0.03 ms latency, you can maximize the potential of a powerful GPU – frames refresh extremely quickly and the smear typical of LCD is practically absent. Brightness up to 1300 cd/m² and high static contrast are a big plus for HDR content and dark scenes in games, where you easily distinguish details in shadows. Thanks to the ports HDMI 2.1, DisplayPort 1.4, and USB Type‑C Upstream, you have flexible connection options – from desktop PC and console to laptop through one cable.

• 34" Ultra wide OLED panel with 21:9 format, providing more horizontal space for gaming, productivity, and multitasking.
• Curved screen with a curvature radius of 800R for a more immersive picture and more comfortable viewing of the entire screen.

• Refresh rate of 240 Hz and response time of 0.03 ms, suitable for serious competitive gaming with very smooth motion.
• OLED backlighting and static contrast 1500000:1 (Typ.), providing deep black tones and strong visual effect in dark scenes and HDR.
• Maximum brightness up to 1300 cd/m², allowing good visibility even in brighter rooms and more pronounced HDR reproduction.
• Anti-Glare coating and wide viewing angles 178°/178°, ensuring that colors and contrast remain stable, even when you are not directly in front.
• Rich connectivity: 2 x HDMI 2.1 (one with eARC), 1 x DisplayPort 1.4, USB Type‑C Upstream power port, 2 x USB 2.0 Downstream, Ethernet (RJ‑45), and Audio Out for easy integration into a more complex setup.

Who it is suitable for

This monitor is a logical choice if you are aiming for high FPS competitive gaming and want an ultra wide format for better visibility and immersion. It is also suitable for work – timelines in video/audio editors, code, spreadsheets – everything fits more conveniently on 21:9. If your main focus is eSports, but you prefer a smaller diagonal (24–27"), or you do not need 240 Hz and OLED, you might want to look at a more modest and budget model.

The combination of 34" curved ultra wide format, OLED panel, and 240 Hz makes LG 34GX90SA‑W a very strong all-round monitor for gaming and everyday work, maximizing the potential of modern GPUs and high refresh rate games.
