LG UltraWide 34U511A-B 34" Black 2025

The LG UltraWide 34U511A-B is a 34-inch 21:9 IPS monitor with 100Hz refresh and 400 nits brightness. It's a multitasking beast at the right price, and Newegg has it for USD 181, which is USD 119 less than the high end of the market. The 2560 x 1080 resolution means text isn't razor sharp, and the 5ms response time isn't great for competitive gaming. But for productivity-focused buyers who want ultrawide real estate without breaking the bank, this is one of the best values out there.

Let's talk numbers. The 100Hz refresh rate is a nice step up from the standard 60Hz you get on most office monitors. Scrolling feels smoother, and in games you'll notice the difference immediately if you're coming from a 60Hz panel. The 5ms GtG response time is fine for casual gaming, but it's not going to impress anyone who's used to a 1ms gaming monitor. There's a reason this sits right around the middle of the pack in our performance rankings, at the 54th percentile.

The 400 nits of brightness is genuinely useful. It's bright enough to fight off glare in a well-lit office, and the DisplayHDR 400 certification means it can technically accept an HDR signal. Just don't expect real HDR performance. With 90% sRGB coverage and an 8-bit panel, colors are decent but not spectacular. The color performance lands in the 83rd percentile, which is well above average for this class. For productivity work, that's plenty. For color-critical photo or video work, you'll want something with wider gamut coverage.

The ultrawide space has gotten crowded, and the 34U511A-B sits in an awkward spot. Compared to something like the Samsung Odyssey G7 G75F, you're giving up a lot of gaming performance. The G7 has a much higher refresh rate and faster response time, but it's also a 16:9 panel and typically costs more. If gaming is your priority, the G7 is the better call. If productivity and screen real estate matter more, the LG makes a stronger case.

Against the MSI MAG 271QPX QD-OLED or the ASUS ROG Strix XG27ACDNG, there's really no contest on image quality. Those are OLED panels with vastly better contrast and color. But they're also 27-inch 16:9 displays and cost significantly more. The LG's advantage is raw screen width and price. The Dell S2725QC is another interesting comparison, it's a 27-inch 4K panel that will give you much sharper text, but you lose the ultrawide aspect ratio and the 100Hz refresh. Different tools for different jobs.

Here's where things get interesting. The price on this monitor swings wildly depending on where you buy it. In the US, we're seeing listings from USD 181 all the way up to USD 300. That's a USD 119 spread, which is significant. If you can snag it near the low end of that range, this is an absolute steal. At the high end, you're getting into territory where you could start looking at 1440p ultrawides or higher refresh rate panels.

Newegg has the best deal right now at USD 181, and that's the price that makes this monitor make sense. At that price point, you're getting a 34-inch IPS ultrawide with 100Hz refresh for less than what many 27-inch 1080p monitors cost. The value proposition is strong, but only if you shop around. Don't pay USD 300 for this when you can get it for USD 181 with a little patience.

The LG UltraWide 34U511A-B is one of those monitors that makes you wonder why you put up with a 16:9 screen for so long. It's a 34-inch IPS panel with a 21:9 aspect ratio, which means you get a whole lot of horizontal room. The resolution is 2560 x 1080, so it's not a pixel density monster, but for the price this thing often sells at, it's a compelling way to get into the ultrawide game without selling a kidney.

Who's this for? Honestly, it's for the multitasker who lives in spreadsheets, code editors, and browser tabs. The 21:9 format lets you run two full-size windows side by side without feeling cramped. LG markets it for both work and casual gaming, and that's fair. The 100Hz refresh rate and FreeSync support mean it's not a slouch for lighter titles, but the 5ms response time and 1080p vertical resolution tell you this isn't a competitive esports panel.

What makes it interesting is the value proposition. You're getting a 34-inch ultrawide IPS screen with 400 nits of brightness and DisplayHDR 400 certification. The social proof on this thing is through the roof, sitting in the 95th percentile in our database. People who buy it tend to really like it. But there are trade-offs, and we'll get into those.

If you're a competitive gamer, this monitor isn't for you. The 5ms response time and 100Hz refresh rate are fine for casual play, but they'll hold you back in fast-paced shooters or fighting games where every millisecond counts. Look at something like the Samsung Odyssey G7 G75F or a dedicated gaming panel with 144Hz or higher refresh and 1ms response.

Also skip this if you do color-critical work. The 90% sRGB coverage and 8-bit panel are fine for general use, but if you're editing photos or video professionally, you'll want something with wider gamut coverage like Adobe RGB or DCI-P3. And if you're sensitive to pixel density, the 2560 x 1080 resolution on a 34-inch screen might bother you. Text won't be as crisp as it would be on a 27-inch 1440p or 4K panel. In that case, the Dell S2725QC with its 4K resolution would be a better fit, though you'd lose the ultrawide aspect ratio.

For the multitasker on a budget, this monitor is easy to recommend. If you spend your days juggling spreadsheets, documents, and browser windows, the 21:9 format is genuinely transformative. The 100Hz refresh rate makes everything feel snappier, and the IPS panel gives you good viewing angles. At USD 181 from Newegg, it's a no-brainer.

For gamers, it's a more nuanced call. The 100Hz refresh and FreeSync support make it perfectly fine for casual gaming, but the 5ms response time and 1080p vertical resolution hold it back. If you're into fast-paced shooters or competitive games, look elsewhere. If you play slower games or mostly use your PC for work with some gaming on the side, this monitor does double duty admirably.
