LG 34GX90SA-W OLED gaming monitor 34-inch
Product description
A high refresh OLED gaming monitor is all about making motion feel effortless, and the LG 34GX90SA-W is built around that idea. With a 240Hz refresh rate and extremely fast response timing, gameplay can feel smoother and more responsive during fast action. It also brings an ultra wide 34-inch curved WQHD display for deeper immersion, plus smart entertainment options through webOS. 🎮
If you want a single screen that supports competitive gaming while also serving as a streaming and cloud gaming display, this LG Ultragear model gives you that flexibility. The steep 800R curve helps pull your view toward the center of the action, and the OLED picture aims for deep blacks and bright highlights for high contrast scenes. 🖥️
Key features
The 34-inch WQHD OLED curved panel is designed to keep you fully engaged with the game, not just watching it. The 800R curve wraps around your field of view, extending your peripheral presence so action feels more immersive. This kind of curvature is especially noticeable when you are tracking movement across the screen during gameplay. For many players, that “in the action” feeling is as important as raw performance.
Speed is a core part of the experience here. The monitor is described as delivering up to 240Hz refresh rate and near instantaneous OLED response performance at 0.03ms GtG. According to LG, the faster OLED speed can help reduce lag and ghosting, which matters when you are reacting quickly to opponents. With that combination, smoother scenes and steadier motion are the goal when things get hectic. 🚀
Frame sync support helps keep visuals consistent across supported gaming systems. The monitor is listed as NVIDIA G-SYNC compatible and AMD FreeSync Premium, targeting smoother, tear free visuals and reduced stutter. In practical terms, that can make fast scenes feel more stable when your frame rates fluctuate.

What to know
This display also focuses on immersion and clarity through its curve and anti glare approach. The 800R curve is called out as a steep curvature that surrounds you in the action, extending your periphery and pulling you deeper into what is happening on screen. At the same time, the anti glare design is meant to reduce reflections and light distractions so you can stay focused during longer sessions. If your room lighting tends to create glare on screens, the anti glare surface can be a meaningful day to day benefit.
For picture performance, LG highlights OLED benefits such as deep blacks and brilliant detail. The monitor is described as supporting DisplayHDR True Black 400, which targets strong contrast for dark scenes and bright highlights. The original product description also references high color coverage with up to 98.5% of DCI-P3 and a 1.5M:1 contrast ratio. While actual results can vary by content and settings, the intent is clear: make in game visuals look more vivid and less washed out.
The smart side is handled through webOS, turning the monitor into a streaming and cloud gaming screen without needing a separate gaming device for every session. The listing mentions built-in access to streaming apps such as Netflix, Prime Video, the Apple TV app, Disney+, and HBO Max, along with webOS cloud game connectivity. It also references NVIDIA GeForce NOW, amazon Luna, and Blacknut accessible directly from the webOS home screen. If you want one display that can switch between gaming and entertainment quickly, that built in platform is a major convenience. 📺
Who it’s for
It’s a solid pick if you play fast paced games and care about motion smoothness and reduced visual disruption during action. You’ll appreciate it if you want an ultra wide curved display for immersive gameplay, plus a smart TV like platform through webOS for streaming and cloud gaming. It may not be a great match if you only game casually and don’t need a high refresh OLED setup or an ultra wide curved format. If your priority is maximum simplicity without smart platform features, you may prefer a more basic display setup.
