LG UltraGear LG UltraGear 45" WQHD 2K 1440P 240Hz AMD FreeSync Review

The LG UltraGear 45GX900A-B is a massive, curved OLED gaming monitor built for immersion. Its 240Hz OLED combo delivers buttery smooth motion with perfect blacks. Just know the 275-nit brightness is modest for HDR, and the pixel density isn't super sharp. Prices range from $950 to $1,186, so shop around. Recommended for dark-room gamers who want a cinematic, fluid experience above all else.

Let's talk about the LG UltraGear 45GX900A-B. It's a 44.5-inch curved OLED ultrawide that wants to be your entire gaming command center. With a 240Hz refresh rate and that classic OLED infinite contrast, it's built for immersion first and everything else second. You're not just buying a monitor, you're buying a viewport.

This thing is for the PC gamer who wants to feel surrounded by the action without needing a triple-screen setup. The 800R curve wraps around you, and at 21:9, games that support the aspect ratio feel incredibly cinematic. It's also surprisingly good for productivity, scoring a 73.8 in our professional category, thanks to that massive real estate for multitasking.

What makes it interesting is the combination of OLED's perfect blacks and a 240Hz refresh rate. That's a pairing you don't see every day, especially at this size. It promises buttery smooth motion with the pixel-level precision and instant response that OLED is famous for. It's a spec sheet that reads like a wishlist for competitive and immersive gaming.

The numbers back up the hype. A 240Hz refresh rate puts it in the 83rd percentile for performance, which means it's faster than most gaming monitors out there. Combine that with the near-instant 0.03ms GtG response time of OLED, and you get motion that's essentially blur-free. Fast-paced shooters and racing games feel incredibly crisp, with no smearing to distract you. The G-Sync Compatible and FreeSync Premium Pro support means screen tearing is a non-issue, keeping everything smooth even when frame rates dip.

Now, the elephant in the room is the brightness. At 275 nits, it's not the brightest panel. In our data, its color score lands in the 83rd percentile, which is great for contrast and color volume, but HDR highlights won't sear your retinas like on some Mini-LED screens. The HDR10 support works with that infinite contrast to deliver deep, realistic shadows, but don't expect a sunbeam to blind you through your window. For a dark room setup, it's phenomenal. For a very bright, sunlit room, you might wish for more punch.

Pricing is a bit of a spread, swinging from $950 to $1,186 across different vendors. That's a $236 difference, so shopping around is crucial. At the lower end of that range, you're getting a lot of screen and premium tech for the money. At the higher end, it starts to bump against more feature-packed or higher-resolution alternatives.

You're paying for the OLED panel and the high refresh rate first. The value proposition is clear: if your top priorities are infinite contrast, perfect blacks, and super smooth motion in a huge, curved format, this monitor delivers a specific experience that's hard to replicate. Just know that you're trading off peak HDR brightness and pixel sharpness for that OLED magic.

The most direct competitor is probably the ASUS ROG Swift 32" 4K QD-OLED. That one gives you a higher pixel density and likely better brightness, but on a smaller, flat screen. It's a trade between sheer immersive size and curve versus sharper image quality. The Samsung Odyssey Neo G9 57" is a different beast entirely, with a dual 4K resolution and Mini-LED backlight for insane brightness, but it's also in a completely different price league.

Then there's LG's own UltraGear 45" with Dual Mode. That one can switch between 4K and a super high FHD refresh rate, offering more versatility but likely without the perfect blacks of OLED. And if you just want a big, fast screen and don't care about OLED, the MSI 32" 4K 240Hz offers blinding speed and resolution in a more traditional package. This LG carves its niche by being the biggest curved OLED gaming screen at this refresh rate.

Skip this monitor if you're a competitive esports player who needs the absolute fastest pixel response above all else and plays in a bright room. While the 240Hz is great, there are faster TN or dedicated 360Hz+ panels that might give a slight edge in the most reaction-time-sensitive scenarios, and they're often brighter. Also, skip it if you're a graphic designer or video editor who needs color-accurate, bright HDR for professional work. The color volume is great, but the 275-nit peak brightness and potential text fringing on non-gaming content make it less than ideal for color-critical production. For those users, a high-brightness, flat 4K IPS or a professional-grade OLED would be a better investment.

Buy the LG UltraGear 45GX900A-B if your gaming den is dimly lit and you live for immersion. It's for the player who values fluid, blur-free motion and the dramatic depth of OLED's contrast above all else. The curve and size make single-player campaigns feel epic, and the high refresh rate keeps competitive games feeling responsive. It's a fantastic centerpiece for a dedicated gaming setup.

Think twice if your workspace is flooded with sunlight, if you do a ton of text-based work where pixel sharpness is critical, or if you need to move your monitor around. The lower brightness and pixel density are real compromises. Also, with so few user reviews, it's a bit of a leap of faith compared to more established models. For those folks, a 32" 4K OLED or a high-refresh Mini-LED monitor might be a safer, more versatile bet.
