If your desk currently holds two mismatched monitors and a nest of cables, a single 34-inch ultrawide solves both problems at once. The LG 34WR55QK-B targets exactly that setup: one curved panel, one USB-C cable to your laptop, and enough horizontal room to keep a document, a browser, and a chat window visible without constant shuffling.
This LG 34WR55QK-B monitor review focuses on where the 3440 x 1440 panel earns its keep: everyday work with heavy multitasking, light creative editing, and casual gaming at 100Hz.
- 21:9 UltraWide - The 21:9 UltraWide WQHD (3440 x 1440) monitor is great for work. The widescreen allows you to see everything you're working on, with multiple windows open, all on one screen.
- Color Gamut - Immerse yourself in a world of brilliant color from HDR10 that helps enhance picture quality and up to 99% sRGB color gamut expression to make games pop.
- OnScreen Control - You can customize the workspace by splitting the display or adjusting basic monitor options with just a few mouse clicks.
The spec sheet reads like a productivity monitor with gaming manners: a VA panel with a 3000:1 contrast ratio, HDR10 support, FreeSync, and 65W power delivery over USB-C. The stand adjusts for height and tilt, while the three-sided slim bezel keeps the frame mostly out of your peripheral vision.
Bottom Line
For anyone replacing a dual-monitor setup or docking a laptop daily, this ultrawide covers the practical bases at a sensible price. Check current availability and pricing on Amazon.

For a broader look at the category, our roundup of top ultrawide gaming monitors covers higher-refresh alternatives.
21:9 Curved WQHD Workspace
Horizontal space is the main reason to buy this panel. At 3440 x 1440, you get roughly 34% more pixel width than a standard 27-inch 1440p display, which translates to three usable columns of windows instead of two cramped ones.
The 0.23mm pixel pitch keeps text sharp at a typical desk distance without scaling. Spreadsheets extend farther right before you scroll, and timeline-based work in video or audio editors benefits from the extra width, obviously.
LG’s OnScreen Control software handles window splitting through screen presets, though many people find Windows Snap or a third-party tiling tool faster. The gentle curve also reduces the head-turning a flat 34-inch panel demands.
USB-C Laptop Docking and Connectivity
A single USB-C cable carries video, data, and up to 65W of charging power, making this a functional laptop dock for most ultrabooks. That 65W figure handles a MacBook Air or a 13-inch Windows laptop comfortably; a 16-inch workstation under heavy load will drain slowly, so keep the original charger nearby.
Two HDMI inputs plus DisplayPort mean a desktop, a console, and a laptop can all stay connected. The two downstream USB ports handle a keyboard and mouse, though anyone needing Ethernet or card readers will want something like a USB-C multiport adapter alongside it.
100Hz Motion and HDR10 Color
The 100Hz refresh rate with FreeSync makes cursor movement and scrolling noticeably smoother than on a 60Hz panel. It also handles single-player gaming well.
VA panels bring strong contrast, and the 3000:1 ratio shows in dark scenes where blacks look deep instead of grey. The tradeoff is dark-scene smearing in fast motion, which competitive shooter players will notice.
Dynamic Action Sync helps trim input lag, but this panel targets a different audience than a 240Hz OLED. HDR10 support works more as a compatibility feature than a spectacle, since 300 nits of peak brightness limits real highlight impact.
The 99% sRGB coverage keeps colors accurate for web and office work. Reader Mode cuts blue light for long document sessions.
Ergonomics and Desk Fit
Height and tilt adjustment come standard, which is uncommon at this price and genuinely useful for getting the top of the screen at eye level.
At 31.9 inches wide and 10.2 inches deep with the stand, the monitor needs a desk of at least 40 inches to feel comfortable. The 15.2-pound weight makes repositioning easy for one person.
Swivel and pivot are absent, so a wall or arm mount is the answer if you rotate your display often. Pairing it with ergonomic peripherals rounds out a workstation that stays comfortable through long sessions.

- Two HDMI ports plus DisplayPort for multi-device desks
- Picture-by-Picture displays two sources side by side
Cons
- No built-in speakers, so external audio is required

Customer Reviews
Buyer feedback skews strongly positive, with most owners describing it as a straightforward upgrade from smaller or older displays.
What Buyers Praise Most
Picture quality draws the most consistent praise, particularly from people running multiple applications simultaneously. Several owners mention it replaced an older setup and immediately felt like a step forward.
The USB-C connection gets specific mention from laptop users who appreciate the single-cable simplicity. Adjustability of the stand comes up repeatedly, as does the ease of wall mounting with the right hardware.
Value for the money is a recurring theme, with buyers noting the feature set feels generous for the price. Repeat LG buyers point to consistent build quality across their purchases.
Concerns Buyers Mention
The missing speakers surprise some buyers who assumed a display this size would include them. One reviewer described picture quality as adequate for business use without being exceptional, which fits a VA panel at this tier.
USB-C charging strength drew a note from one laptop user: it maintains the battery under normal load without charging quickly.
Conclusion
For laptop-based work that needs more room and fewer cables, the 34WR55QK-B delivers the essentials without asking you to pay for gaming features you will not use.
Skip it if you play competitive shooters, need HDR with real punch, or want built-in audio. Choose it if you spend your day in documents, spreadsheets, and browser tabs, and you want one cable running to your laptop.
Budget an extra $30 to $60 for desk speakers or a soundbar, then plan on a desk at least 40 inches wide. Anyone wanting higher refresh rates should compare it against the LG 34WP60C-B ultrawide before deciding.
Frequently Asked Questions
Is the LG 34WR55QK-B good for working from home?
Yes, it suits home office work well, with the 3440 x 1440 resolution fitting three window columns side by side. The height-adjustable stand and Reader Mode help during long sessions at the desk.
Does the LG 34WR55QK-B have built-in speakers?
No, this model ships without integrated speakers. You will need desktop speakers, a soundbar, or headphones connected through the monitor’s headphone jack or directly to your computer.
Can the LG 34WR55QK-B charge a laptop through USB-C?
Yes, the USB-C port supplies up to 65W of power delivery while carrying video and data on the same cable. Ultrabooks charge normally on that budget, while larger laptops with 90W or higher requirements will hold their charge under light use but drain during demanding tasks.
Is the LG 34WR55QK-B suitable for gaming?
It handles single-player and casual gaming well, thanks to 100Hz refresh, FreeSync, and a 5ms response time. Competitive players will want a faster panel, since VA response times produce visible smearing in dark, fast-moving scenes.
Can the LG 34WR55QK-B display two input sources at once?
Yes, Picture-by-Picture splits the screen between two connected devices, such as a work laptop and a gaming console. Setup runs through LG’s OnScreen Control software, which you can download from LG’s support site.
