Snapshot

The 30-Second Version

The LG UltraGear 45GX900A-B is a colossal 45-inch OLED gaming monitor with a wild 800R curve and blistering 240Hz speed. Color and contrast are among the best we've seen, but the low PPI means text isn't crisp. A newer 5K2K version exists now, so hunt for a deal on this one or step up for sharper visuals.

Pros & Cons

Pros

  • Absolutely stunning immersion from the 45-inch screen and 800R curve. 98th
  • Blazing fast 240Hz refresh and 0.03ms response with perfect motion clarity. 97th
  • Excellent color accuracy (98.5% DCI-P3) and high peak brightness for HDR. 88th
  • Comprehensive connectivity including USB-C with 65W power delivery. 86th

Cons

  • Text clarity is mediocre due to low pixel density at this size.
  • Extreme curve can feel overwhelming or cause distortion in some scenarios.
  • No 4K option, resolution is capped at 3440x1440.
  • Newer 5K2K OLED ultrawides like the 45GX950A-B make this feel last-gen.

The proof

Performance

Speed-wise, this monitor is among the best we've tested. At 240Hz with OLED response times, motion blur is virtually non-existent. FreeSync Premium Pro and G-Sync compatibility both work flawlessly, so you get tear-free gameplay on AMD and NVIDIA cards. The 3440x1440 resolution at this size means pixel density sits around 84 PPI, similar to a 27-inch 1080p screen. It's fine for gaming but can make text look soft. HDR content shines with those deep OLED blacks and 1300-nit peaks, though DisplayHDR True Black 400 certification doesn't tell the full story, highlights are genuinely striking. Input lag is imperceptible, and the panel handles fast-paced shooters without a hint of ghosting.

vs Competition

The LG 45GX900A-B now faces its own successor, the 45GX950A-B, which bumps resolution to 5K2K (5120x2160) and adds DisplayPort 2.1, fixing the text clarity complaint while keeping that massive 45-inch OLED canvas. The ASUS ROG Strix XG27AQDMG is a totally different beast, a 27-inch 1440p 240Hz OLED that's sharper and far more desk-friendly, but it can't touch the LG's sheer scale. MSI's MPG 272URX QD-OLED goes 4K at 27 inches with quantum dot color, perfect if you want pixel density and vibrancy over size. Dell's U4025QW remains the productivity king with its 5K2K IPS Black panel and built-in KVM, but it's a 60Hz panel that gamers will find sluggish. This LG is still the pick for pure, unapologetic gaming immersion, just know a sharper version now exists.

Price

Value & Pricing

Pricing on this monitor is a mess. We've seen it listed from around $1,000 all the way up to an absurd $30,384. At the low end, it's a fantastic value for a colossal OLED gaming experience. At the high end, you're getting ripped off. Shop around aggressively and don't pay anywhere near the upper range. If you can snag it near $1,000, it's a compelling piece of kit that undercuts many smaller high-refresh OLEDs on a dollar-per-inch basis.

Overview

The LG UltraGear 45GX900A-B is a bold statement. It's a massive 45-inch curved OLED that prioritizes sheer immersion over pixel-perfect clarity. If you want a display that wraps around you and makes every game feel like an IMAX experience, this thing delivers in spades. The 800R curve is aggressive, but it pulls you deep into the action, and the 240Hz refresh rate with 0.03ms response time keeps motion ridiculously smooth.

We've seen our share of big screens, but this one stands out for its contrast and HDR punch. Peak brightness hits 1300 nits in small highlights, and the 98.5% DCI-P3 color coverage means games look vibrant without feeling oversaturated. Just know that 1440p stretched across 45 inches isn't the sharpest for desktop work. Text clarity takes a hit, and you'll notice it if you read a lot. For gaming, though, it's an absolute beast.

Common Questions

Q: Does this monitor actually work with NVIDIA G-Sync?

Yes, it's G-Sync Compatible certified. We've tested it with an RTX 4090 and experienced no tearing or flickering, even in demanding games.

Q: Is 1440p sharp enough on a screen this big?

For pure gaming, yes. Graphics look great and you don't notice pixelation during fast motion. But for reading text or coding, the lower pixel density (around 84 PPI) can make fonts look a bit fuzzy.

Q: Can I mount this to a monitor arm?

Absolutely. It supports VESA 100x100 mounting. Just make sure your arm can handle the 13.5 kg (29.8 lbs) weight, this thing is heavy.

Who Should Skip This

Skip this one if you need sharp text for work or plan to split-screen documents all day. The low PPI will annoy you. Also pass if desk space is tight, it demands serious real estate. And if you're sensitive to aggressive screen curvature, the 800R bend might feel disorienting rather than immersive. For productivity-focused users, a 4K flat ultrawide like the Dell U4025QW makes way more sense.

Verdict

This monitor is for gamers who want the biggest, most immersive ultrawide experience possible without buying a projector. It's incredible for sim racing, RPGs, and anything atmospheric. The speed is top-tier, and OLED contrast makes every scene pop. Just don't expect it to double as a sharp productivity monitor, text lovers will wince. The new 45GX950A-B fixes the resolution complaint, so if you can swing the higher price, that's the smarter long-term buy. But if you find this one at a deep discount, it's still one heck of a ride.
