Design and Build
The LG 34WR55QK-B features a three-sided virtually borderless design, which helps it blend cleanly into a multi-monitor setup or stand alone as a sleek centerpiece. The curved panel is intended to provide a more immersive viewing experience and reduce eye strain by bringing the edges of the wide screen closer to the user’s natural field of view. The matte screen surface helps minimize glare from ambient lighting.
Ergonomics are addressed through a stand that offers both height and tilt adjustment, allowing users to find an optimal viewing position. This flexibility supports longer work sessions by promoting better posture. The overall aesthetic is professional and modern, suitable for both home offices and corporate environments.
Performance and Features
Display Performance
The core of this monitor is its 34-inch UltraWide WQHD (3440 x 1440) curved IPS panel. The 21:9 aspect ratio is the standout feature for productivity, allowing users to view multiple full-size windows side-by-side without the need for a dual-monitor configuration. The 100Hz refresh rate offers smoother motion than standard 60Hz office monitors, providing a slight benefit for general use and casual gaming, though it is not targeted at competitive esports. HDR10 support and up to 99% sRGB color gamut coverage are listed, suggesting the monitor is capable of vibrant and reasonably accurate colors suitable for general creative work and media consumption.
Connectivity and Ports
Connectivity is a major strength. The inclusion of a USB Type-C port with up to 65W power delivery simplifies connectivity for modern laptops, allowing video, data, and charging over a single cable. This is complemented by two HDMI ports, a DisplayPort, two USB ports, and a headphone jack. This array supports connecting multiple source devices simultaneously, which is essential for the Picture-by-Picture (PbP) functionality.
Key Features and Software
LG’s OnScreen Control software is a significant feature, enabling users to easily split the screen into various window configurations and adjust monitor settings via their mouse. This enhances the multitasking potential of the wide screen. The Picture-by-Picture (PbP) mode allows the display to show content from two separate input sources at the same time. For user comfort, Reader Mode reduces blue light emission to help minimize eye strain during extended reading or work sessions. The manufacturer does not list specific security or software update features.
Setup, Support and Ownership
Setup is straightforward, leveraging the standard VESA mount compatibility implied by the adjustable stand and the variety of included video cables typical for a monitor in this class. The USB-C connection offers a particularly clean setup for laptop users. Regarding support and ownership, LG provides standard manufacturer warranties, though the specific duration is not listed in the provided data. The availability of firmware updates or dedicated support software is also not specified. The monitor’s design suggests it is a standalone product without mandatory proprietary accessories.
What Owners Say
Owner feedback indicates a high level of satisfaction with this model. The overall rating is strong, with praise frequently directed toward the immersive UltraWide screen real estate for productivity and the convenience of the USB-C connectivity. The curved design and image quality are also commonly noted as positive aspects. While specific critical excerpts are not provided in the data, the high rating suggests that most concerns are minor relative to the praised features.
Pros and Cons
Pros
- Excellent multitasking capabilities with 21:9 UltraWide aspect ratio
- Versatile connectivity featuring USB-C with 65W power delivery
- Useful productivity software with OnScreen Control and PbP mode
- Good color performance with HDR10 and 99% sRGB coverage
- Ergonomic stand with height and tilt adjustment
- Eye comfort features like Reader Mode for reduced blue light

Who Should Buy It (and Who Should Skip It)
The LG 34WR55QK-B is an ideal choice for productivity power users, remote professionals, and students who benefit from having multiple documents, browsers, and communication apps open concurrently. It is also well-suited for those with modern laptops seeking a single-cable docking solution via USB-C. Creative professionals doing color-sensitive work may find the 99% sRGB coverage sufficient for non-critical tasks, but those requiring wider gamuts like Adobe RGB or DCI-P3 should look elsewhere.
This monitor is not the best fit for competitive esports gamers who prioritize very high refresh rates, or for graphic designers and video editors who require absolute color accuracy and flat panels for layout work. Users who need built-in audio should also consider adding external speakers. For more options on curved UltraWide displays, see our guide on the best UltraWide curved monitors.
Final Verdict
The LG 34WR55QK-B successfully carves out a niche as a highly functional productivity monitor. Its greatest strength lies in its thoughtful integration of a expansive 21:9 curved display with practical features aimed at streamlining the workspace. The USB-C port with power delivery is a standout, reflecting modern connectivity needs. While its performance specifications are solid rather than exceptional, they are well-matched to its intended use cases of office work, content creation, and casual entertainment.
When weighed against its potential drawbacks, the monitor’s value proposition is clear. It offers a cohesive package that enhances multitasking efficiency and user comfort. For anyone looking to consolidate their setup and expand their digital canvas without moving to a multi-monitor array, the LG 34WR55QK-B is a compelling contender. It exemplifies how thoughtful feature integration can create a monitor that is more than the sum of its specs. For broader monitor comparisons, visit our reviews category.
FAQs
Does the LG 34WR55QK-B have built-in speakers?
No, the LG 34WR55QK-B does not have integrated speakers according to the provided specifications. It includes a headphone jack for audio output, so users will need to connect external speakers or use headphones for sound.
Can this monitor charge a laptop through the USB-C port?
Yes, the USB Type-C port on this monitor supports power delivery up to 65W. This is sufficient to charge many modern laptops while simultaneously handling video and data transmission, creating a clean single-cable setup.
Is the LG 34WR55QK-B good for photo editing?
It can be suitable for general photo editing due to its 99% sRGB color gamut coverage and WQHD resolution, which provides good detail. However, professionals requiring absolute color accuracy for print or wider color gamuts like Adobe RGB may need a monitor specifically calibrated and designed for that purpose.
What is the benefit of the Picture-by-Picture (PbP) mode?
Picture-by-Picture mode allows the monitor to display content from two different input sources simultaneously. For example, you could have a work laptop connected via USB-C and a personal desktop connected via HDMI showing on the same screen at the same time, which is useful for comparing information or multitasking across two separate systems.
