LG UltraWide 34WR55QC-B 34"

Manufacturer: LG

The LG UltraWide 34WR55QC-B is a 34-inch curved ultrawide monitor built around a VA panel with LED backlighting. It carries a 3440 x 1440 resolution at 109 ppi, a matte anti-glare surface, and wide 178-degree viewing angles both horizontally and vertically, making it a versatile screen for extended desktop work and multimedia use. The monitor supports VESA mounting, tilt adjustment, and portrait mode, and weighs in at 6894 g with a footprint of 810 x 358 x 91 mm.

On the display side, the panel delivers a typical brightness of 300 nits, a contrast ratio of 3000:1, 16.7 million colors, and 99% sRGB coverage with support for color calibration. The refresh rate sits at 100Hz with a 5 ms response time and AMD FreeSync for adaptive sync. Connectivity includes two HDMI 2.0 ports, one DisplayPort 1.4 output, a USB-C port, three additional USB ports, and a 3.5 mm audio jack; there is no Wi-Fi, Ethernet, Thunderbolt, DVI, or VGA. Operating power consumption is rated at 38.4W, dropping to 0.5W in standby, and the monitor does not include built-in speakers, a camera, or a remote control.

Pros
  • The 3440 x 1440 VA panel covers 99% of the sRGB color space and supports color calibration, making it a reliable choice for color-sensitive work
  • A 3000:1 contrast ratio, which is a characteristic strength of VA panels, delivers noticeably deeper blacks and more distinct shadow detail than typical IPS displays
  • The matte, anti-glare surface reduces reflections during use in environments with ambient lighting, without the distortion of a glossy panel
  • Wide 178-degree viewing angles in both directions mean the image remains consistent when viewed from off-center positions
  • VESA mount support combined with tilt adjustment and portrait mode capability provides meaningful flexibility in how the monitor can be positioned and integrated into a workspace
  • Standby power consumption of just 0.5W indicates efficient idle power draw
Cons
  • At 100Hz and with a 5 ms response time, the display falls short of what dedicated gaming monitors offer in terms of refresh rate and motion clarity
  • The monitor has no built-in speakers, so external audio hardware is required for any sound output
  • There is no swivel stand, which limits horizontal angle adjustments without repositioning the entire display or using an aftermarket mount
  • With no Thunderbolt support and HDMI capped at version 2.0, high-bandwidth connection options are restricted for users with newer hardware
  • The absence of Picture-in-Picture means users cannot display content from two sources simultaneously on the same screen
Who is this for?

The LG UltraWide 34WR55QC-B is well-matched to users who spend long hours working across multiple windows or applications, as the 3440 x 1440 ultrawide curved panel provides a substantially wider field of view that supports side-by-side workflows without needing a second monitor. The 99% sRGB coverage with color calibration support makes it a reasonable fit for creative professionals who work in color-managed environments and need reliable, consistent color reproduction. Users who value ergonomic flexibility will also appreciate the VESA mount support, tilt adjustment, and portrait mode capability, which allow the display to be adapted to a range of desk setups and working postures.

Who is this NOT for?

Users looking for a dedicated gaming monitor may find the 100Hz refresh rate and 5 ms response time limiting, as these figures leave noticeable room for improvement when it comes to fast-paced motion clarity and competitive responsiveness. Those who rely on audio output directly from their display will be hindered by the absence of built-in speakers, requiring a separate audio solution. The monitor also lacks Thunderbolt connectivity and caps HDMI at version 2.0, making it a less suitable choice for users with newer, high-bandwidth devices who expect faster or more versatile connection options from their display.
