Snapshot

The 30-Second Version

The 34BQ77QE-B scores 73.9 out of 100, with connectivity and features in the 97th percentile but performance in the 22nd. It's a 34-inch ultrawide productivity monitor with USB-C 90W power delivery and an integrated KVM, which is rare at this size. The 60Hz refresh rate is the main compromise, and US prices swing wildly from $330 to $960, so shop carefully.

Pros & Cons

Pros

  • USB-C with 90W power delivery charges your laptop while driving the display 97th
  • Integrated KVM lets you switch peripherals between two computers 96th
  • 97th percentile connectivity score with HDMI, DisplayPort, USB-C, and Thunderbolt 81st
  • 99% sRGB coverage is well above average for color work 81st
  • 3440 x 1440 resolution gives you tons of horizontal workspace

Cons

  • 60Hz refresh rate lands in the 22nd percentile for performance
  • 5ms response time is slow for fast-moving content
  • 300 nits brightness makes HDR10 support mostly cosmetic
  • Portable score of 14.7 out of 100 means this thing stays on your desk
  • 10.1kg weight makes mounting or moving it a two-person job

What owners think

The Word on the Street

4.2/5 (18 reviews)
👍 Video and photo editors are enthusiastic about the ultrawide format, with several saying they were initially hesitant but now fully recommend it for editing workflows.
👍 Buyers appreciate the extra horizontal space for multitasking, with the 3440 x 1440 resolution being a common highlight in positive feedback.

The proof

Performance

Let's be blunt: the 60Hz refresh rate and 5ms response time are the weak links here. In our database, this monitor's performance lands in the 22nd percentile, which means most displays we test are faster. If you're coming from a 144Hz or 160Hz panel, you'll notice the difference immediately when scrolling or moving windows around. But for static work like documents, spreadsheets, and photo editing, 60Hz is perfectly fine. The 5ms GtG response time won't cause ghosting in office apps, though fast-moving video can look a little soft.

The IPS panel itself is a strong performer for color work. The 99% sRGB coverage puts it in the 79th percentile for color, which is well above average for a productivity monitor. The 8-bit+FRC panel handles gradients smoothly, and the 300 nits brightness is enough for most indoor environments. Just don't expect HDR to blow you away. HDR10 support on a 300-nit IPS panel without local dimming is more about compatibility than actual high dynamic range performance.

vs Competition

Compared to the competition, the 34BQ77QE-B is a specialist. The ASUS ROG Strix XG27UCDMG and MSI MAG 271QPX QD-OLED E2 are gaming-focused OLED panels that run circles around this LG on refresh rate and response time, but they're smaller and lack the ultrawide aspect ratio. The Samsung Odyssey G60SD and Gigabyte M Series OLED MO27U2 SA are similarly performance-oriented. The Alienware AW2725D is a 27-inch 1440p panel that's faster but gives up the extra horizontal space. What none of those competitors offer is the combination of 34 inches of ultrawide real estate, 90W USB-C power delivery, and an integrated KVM. If you need to run two computers through one display and one set of peripherals, this LG is in a class of its own. If you want smooth motion and high refresh rates, every single one of those competitors beats it.

Price

Value & Pricing

Pricing on this monitor is all over the place. US listings range from $330 to $960, which is a $630 spread across five vendors. That's not a typo. The same panel can cost nearly three times as much depending on where you buy it. If you're shopping in the US, do your homework and don't pay anywhere near the top of that range. The $330 price point is genuinely competitive for a 34-inch ultrawide with USB-C and KVM, but at $960 you're entering OLED territory where this monitor gets absolutely destroyed on performance. Canadian buyers see a tighter spread at CAD 1,253 to CAD 1,320, and Japanese buyers have a single listing at JPY 177,119. The value proposition hinges entirely on finding a good price, so shop around before you commit.

Overview

The LG UltraWide 34BQ77QE-B scores a 73.9 out of 100 in our database, which puts it in a weird spot. It's a productivity monster with connectivity and feature scores in the 97th percentile, but the 60Hz refresh rate and 5ms response time drag its performance score down to the 22nd percentile. This is not a gaming monitor, and it doesn't pretend to be. It's a workhorse for people who live in spreadsheets, timelines, and code editors.

The 34-inch 3440 x 1440 IPS panel is curved at 3800R, which is gentle enough to avoid distortion but immersive enough to feel like you've got two monitors without the bezel in the middle. The 99% sRGB coverage and 300 nits brightness are solid for office work, though HDR10 support is more of a checkbox than a feature at this brightness level. The real story here is the USB-C port with 90W power delivery and the integrated KVM, which means one cable can charge your laptop, drive the display, and let you switch peripherals between two machines.

Common Questions

Q: Is this monitor good for gaming?

Not really. The 60Hz refresh rate and 5ms response time put it in the 22nd percentile for performance in our database. You can play games on it, and the 3440 x 1440 ultrawide resolution looks great for slower titles, but fast-paced games will feel sluggish compared to the 144Hz and 160Hz panels available at similar prices.

Q: Can this monitor charge my laptop?

Yes. The USB-C port delivers up to 90W of power, which is enough to charge most ultrabooks and many mid-range laptops while simultaneously driving the display. That's one of the standout features here, and it's part of why the connectivity score lands in the 97th percentile.

Q: How does the KVM feature work?

The integrated KVM lets you connect two computers to the monitor and switch between them using a single keyboard and mouse. You can also use Picture-in-Picture or Picture-by-Picture mode to view both machines simultaneously. This is a huge time-saver for anyone who juggles a work laptop and a personal desktop.

Who Should Skip This

If you care about smooth motion, skip this. The 60Hz refresh rate and 5ms response time put it in the 22nd percentile for performance, which means it's slower than the vast majority of monitors we test. Gamers, video editors working with high-frame-rate footage, and anyone who's used to a 120Hz or 144Hz panel will feel the difference immediately. The 300 nits brightness also means HDR content looks flat, so if you're buying for HDR movies or games, look elsewhere. And at 10.1kg with a portable score of 14.7 out of 100, this is a permanent desk fixture, not something you'll be moving between rooms or taking on the road.

Verdict

The LG UltraWide 34BQ77QE-B is a purpose-built productivity monitor that nails its niche. The 97th percentile connectivity and feature scores tell the real story: this is a display for people who need to manage multiple devices and want a clean, cable-minimal setup. The 73.9 overall score reflects the performance trade-off, but if you're not gaming or watching fast-action content, that trade-off is worth it. The 4.4 out of 5 customer rating from 22 reviews backs this up. Buyers who use it for video editing and photo work are happy. Just make sure you're paying a fair price, because the $330 to $960 US spread means some vendors are charging way too much for what you get.
