LG UltraGear LG UltraGear 39 inch Ultrawide WQHD 2K 1440P 240Hz Review

This is the monitor you buy when you want to feel inside the game, not just watch it. The aggressive 800R curve and OLED speed create an immersive experience that flat screens can't touch, but it's a one-trick pony for dedicated gamers.

The LG Ultragear 39GX900A-B is a monitor that makes a promise and keeps it: it's an OLED speed demon wrapped in a curve so aggressive you'll feel like you're falling into the screen. Forget subtlety. This 39-inch, 240Hz, WQHD panel is built for one thing: to make your games feel faster and look more immersive than anything else on your desk. The one thing to know? It's not a jack-of-all-trades. It's a master of gaming immersion, and it makes zero apologies for it.

What surprised us was how that 800R curve actually works. In our data, ergonomics scored low, but the performance percentile is sky-high at 83rd. That's because the curve isn't just for show. It pulls your peripheral vision into the game, making fast-paced shooters and racing sims feel more intense. Combined with the near-instant 0.03ms pixel response of OLED, the whole experience feels incredibly fluid. The 240Hz refresh rate is the cherry on top, ensuring everything stays buttery smooth.

At just under $1,000, it's a lot of money. But for a dedicated gaming rig, it's worth it. You're paying for that unique combination of large-scale OLED speed and an aggressive curve that you simply can't get anywhere else. If that's your specific fantasy, the price makes sense.

This monitor lives in a weird, awesome niche. The Samsung Odyssey Neo G9 is wider and has more screen, but it's not OLED, so you lose those perfect blacks and instant response. The MSI MPG 32" 4K monitor offers sharper detail, but you trade the immersive curve and likely some refresh rate headroom. And then there's the LG UltraGear 45"—it's bigger and has a dual-resolution mode, but again, it's not OLED. The 39GX900A-B's trick is being the only one that combines this size, this curve, and OLED tech. You pick it for that specific combo, not because it wins on every spec.

If you're a creative pro who needs color accuracy and a flat, predictable image for photo or video editing, this isn't it. Go get a professional-grade IPS panel instead. Also, if your desk is small or you need to frequently adjust your monitor's height and tilt, the sheer size and basic ergonomics here will frustrate you.

We recommend the LG Ultragear 39GX900A-B if your primary goal is maximum gaming immersion and you have the desk space for it. It's a specialized tool, not a daily driver for everyone. The curve is a love-it-or-hate-it feature, but if you love it, nothing else feels quite like this. Just be sure your graphics card can push high frames at 3440x1440 to really take advantage of that 240Hz panel.
