LG UltraGear LG UltraGear GX9 34" UWQHD 2K 1440P 240Hz w/ Review

The LG UltraGear 34GX900A-B is a 34-inch 1440p OLED gaming monitor with a 240Hz refresh rate. It offers exceptional motion clarity and perfect blacks for immersive gaming at a relatively affordable price point, though its brightness is modest. It's a great pick for gamers who want top-tier responsiveness without the premium cost of the latest QD-OLED panels.

If you're hunting for a high-refresh ultrawide gaming monitor that doesn't break the bank, the LG UltraGear OLED 34GX900A-B is a serious contender. It's a 34-inch curved OLED panel with a 3440x1440 resolution and a blistering 240Hz refresh rate, all for around $750. That combo puts it in a sweet spot for PC gamers who want immersive, buttery-smooth motion without needing a supercomputer to drive it. The 800R curve is pretty aggressive, which helps pull you into the action, and you get a decent set of features like a USB-C port with 65W charging and integrated speakers. Our database scores it highest for gaming, which makes sense, but it also holds up well for professional and office work thanks to that OLED contrast.

This thing is fast. The 0.03 ms gray-to-gray response time is essentially instant, which means you get zero ghosting or smearing in fast-paced games. The 240Hz refresh rate lands in the 83rd percentile for performance, so it's near the top of the heap for smoothness. In practice, that means everything from first-person shooters to racing games feels incredibly fluid. The trade-off for that speed is brightness; at 275 nits, it's not the brightest monitor out there. HDR content looks good thanks to the perfect blacks of OLED, but don't expect the eye-searing highlights you'd get from a Mini-LED panel. For SDR gaming in a dim or normal room, it's more than enough.

At around $745, this monitor sits in a interesting spot. It's significantly cheaper than the newer 240Hz QD-OLED ultrawides from brands like Alienware or ASUS, which often start well over $1,000. You're trading some peak brightness and maybe a few extra features for that lower price. If your main goal is getting OLED motion clarity and high refresh rates on a budget, this LG is one of the most accessible ways to do it. Just know that you're buying a slightly older OLED panel tech, not the latest and brightest generation.

The most direct competitor is probably the ASUS ROG Swift 32" 4K QD-OLED. That one is bigger, has a higher 4K resolution, and uses newer QD-OLED tech for better brightness and color volume. But it's also more expensive and 'only' runs at 240Hz for 4K, which is much harder to drive. The LG gives you a more manageable 1440p ultrawide resolution that's easier to hit high frame rates with. Then there's the Samsung Odyssey Neo G9 series. Those are super-ultrawide or dual 4K beasts with Mini-LED backlights for insane brightness, but they use VA panels with slower pixel response times. If your priority is pure speed and contrast over brightness, the LG OLED wins. For a more productivity-focused alternative, a Dell UltraSharp with an IPS panel would be brighter and sharper for text, but you'd lose the gaming performance.

Skip this monitor if you work in a super bright, sunny room—the 275-nit brightness will struggle. Also, if your daily workflow involves leaving static spreadsheets or toolbars on screen for 8+ hours, the risk of OLED burn-in might cause you anxiety; a good IPS monitor would be a safer bet. And if you're looking for the absolute best HDR experience with bright highlights, you'll want a monitor with a higher peak brightness, like a Mini-LED model.

So, should you buy it? If you're a PC gamer who values smooth, clear motion above all else and you've been wanting to try OLED without spending a fortune, this is a fantastic gateway drug. The 240Hz refresh and instant response make games feel incredible, and the ultrawide format is immersive. But if you work in a very bright room, need a monitor for color-critical HDR work, or are paranoid about OLED burn-in from static desktop elements, you should look at a bright IPS or Mini-LED model instead. For the right person—a gamer who plays in a controlled light environment—this LG delivers a premium experience at a mid-range price.
