The 30-Second Version

A stunningly immersive 39-inch OLED gaming monitor with a curve so deep it feels like a hug for your eyeballs. If you want to be in the game, not just watching it, this is your screen.

Overview

The LG UltraGear 39 inch Ultrawide is the monitor you buy when you're done pretending a flat screen is immersive enough. That aggressive 800R curve wraps around your field of view in a way that feels less like a monitor and more like a cockpit. It's a massive 39-inch OLED panel running at 3440x1440 and a buttery 240Hz, and the image quality is genuinely stunning. If you're a gamer who wants to be pulled into the world, not just look at it, this thing delivers. The one thing to know? This is a gaming-first, entertainment-second monitor that can do some work on the side, but its moderate pixel density means it's not a text-sharpness champion.

Performance

The speed here is ridiculous, and that's not hyperbole. A 240Hz refresh rate paired with a 0.03ms response time puts this in the 98th percentile for performance in our database. It's one of the absolute best right now for motion clarity. What surprised us most wasn't just the speed, but how the OLED panel's perfect blacks and 98.5% DCI-P3 color coverage make even fast-paced competitive games look like art. You're getting elite-level responsiveness without sacrificing visual fidelity, and the G-Sync and FreeSync Premium Pro support keeps everything tear-free. The 275-nit typical brightness might sound low on paper, but that 1300-nit peak in small highlights makes HDR pop in a dark room.

The Word on the Street

4.4/5 (68 reviews)
👍 Owners are blown away by the sheer immersion of the 39-inch size and 800R curve, saying it's the perfect sweet spot for a desk without being overwhelming.
👍 The color quality and perfect OLED blacks get a ton of love, with many users calling the picture exceptional right out of the box.
🤔 A recurring nitpick is that the stand design is a bit of an eyesore and takes up too much desk space, though the monitor itself feels premium.

Value & Pricing

Pricing on this monitor is all over the map, with a wild spread from $997 to over $476,000 across vendors. Obviously, ignore the absurd high end and look for it around that $1,000 mark. At that price, it's a strong value for a large-format OLED gaming display. Multiple owners specifically call out the value for the price as a pleasant surprise, and we agree. Just make sure you're buying from a reputable store_name with a sane price tag.

vs Competition

The most direct competitor is the Alienware AW3423DWF, a 34-inch QD-OLED that's been the reigning champ for ultrawide gaming. The LG fights back with a bigger 39-inch canvas and a much more aggressive curve that the Alienware simply doesn't have. The Alienware gets brighter in SDR and has a slightly sharper image due to the smaller screen, but the LG's sheer size and immersion are on another level. If you're considering a super-ultrawide like the Samsung Odyssey Neo G9 57", know that the LG is a more manageable, less demanding beast for your GPU and your desk. For pure gaming immersion, the LG is the new one to beat.

Common Questions

Q: Is the 800R curve too aggressive for everyday use?

Not at all. It looks severe in photos, but in person it wraps your peripheral vision naturally. Several owners use it for work and streaming all day with zero complaints. You adapt to it in about five minutes.

Q: Can I use this monitor with my PS5 or Xbox Series X?

Yes, and it works great. The HDMI 2.1 ports support 120Hz from consoles, and while you won't get the full 240Hz or ultrawide aspect ratio in every game, the OLED picture quality and low input lag make it a killer console display.

Q: How are the built-in speakers?

Surprisingly decent for monitor speakers. They're clear and get loud enough for casual gaming or YouTube. You'll still want a headset or desktop speakers for anything serious, but they're not the tinny afterthought you might expect.

Who Should Skip This

If you're looking for a razor-sharp productivity monitor for reading and writing all day, this isn't it. The 3440x1440 resolution stretched across 39 inches gives you a moderate pixel density that makes text look a little soft. Go get a 4K panel like the Dell UltraSharp U4025QW instead. Your eyes will thank you after hour eight of staring at spreadsheets.

Verdict

The LG UltraGear 39 inch is a phenomenal gaming monitor that nails the immersive experience. The 800R curve and OLED panel combine to create something special that flat or even mildly curved screens can't touch. It's not the best all-rounder if you're splitting time 50/50 with spreadsheet work, but if your primary goal is to get lost in your games, this is an easy recommendation. Buy it for the immersion, stay for the speed and stunning picture quality.
