Overview

The LG 34WQ75C-B is a 34-inch curved IPS panel running 3440×1440 — the QHD UltraWide resolution that has become the de facto standard for productivity-focused large monitors. At 109 PPI across 34 inches, sharpness is solid rather than exceptional, but the resolution is not the story here. The headline capability is the port configuration: a single USB-C connection delivers 90W of charging power, video signal, data, and network pass-through (via the built-in RJ-45 LAN port) to a connected laptop. The built-in KVM switch then lets a second computer share the same keyboard, mouse, and display without a separate switch box. That combination — one cable, two computers, wired ethernet included — is the engineering case for this monitor over simpler alternatives.

The 34WQ75C-B is designed for professionals who hot-desk between a laptop and a desktop, or who manage two machines simultaneously. Developers, creative professionals, and hybrid-work users who want a clean desk without a proliferation of adapters and cables will find the feature set well-matched to that workflow. The 99% sRGB coverage makes it usable for color-sensitive work without requiring external calibration for standard web and print outputs. The 21:9 aspect ratio adds meaningful horizontal workspace for multi-window layouts, code editors with split panes, or video timelines. The 7W×2ch MaxxAudio speakers are better than average for integrated monitor audio — acceptable for calls and reference listening without reaching for external speakers.

Pros & Cons

👍 Pros

  • 90W USB-C Power Delivery charges most laptops while carrying video and data — a true single-cable docking solution.
  • Built-in KVM switch eliminates the need for a separate hardware unit when managing two computers from one desk.
  • 3440×1440 IPS panel covers 99% sRGB (typical), providing accurate color reproduction for photo editing and design work at 21:9.
  • Integrated RJ-45 LAN pass-through adds wired ethernet to laptops over the USB-C connection without a dongle.
  • 7W×2ch speakers with MaxxAudio are genuinely usable for video calls and casual media — a rare quality at this monitor tier.

👎 Cons

  • HDR 10 support is entry-level — the IPS panel lacks local dimming zones, so HDR performance is noticeably below OLED or mini-LED alternatives.
  • No USB-C upstream port pairing with the KVM means the second computer must connect via DisplayPort or HDMI, losing the single-cable docking benefit for that host.
  • Curved IPS panels at this radius can exhibit slight color shift at extreme horizontal viewing angles compared to flat IPS alternatives.
  • At 34 inches with 3440×1440, pixel density is adequate but not high-DPI — users moving from a Retina-class display will notice the difference.
  • The 21:9 aspect ratio requires application-level support for optimal window management; some legacy software does not scale well to ultrawide.

Frequently Asked Questions

Yes. The USB-C port delivers 90W of power — enough to charge most mainstream business and creative laptops while simultaneously transmitting video and data over a single cable. Check your laptop's USB-C power draw; units requiring more than 90W may charge slowly under load.
The KVM (Keyboard, Video, Mouse) switch lets you control two connected computers using one set of peripherals — keyboard and mouse plugged into the monitor's USB hub switch between hosts. Combined with the Dual Controller software, you can operate both machines from a single workspace without a separate hardware KVM box.
At 34 inches, 3440×1440 yields approximately 109 PPI — comparable to a 27-inch 2560×1440 display. Text and UI elements are crisp for typical desktop viewing distances, and the extra horizontal real estate (21:9 aspect ratio) is the primary productivity advantage over a 16:9 equivalent.
The 34WQ75C-B supports HDR 10, which enables improved peak brightness and contrast metadata compatibility with HDR content. Note that IPS-based HDR implementations at this price tier are functional rather than reference-grade — local dimming depth is limited compared to OLED or high-zone FALD panels.
The RJ-45 LAN port lets you run a wired ethernet connection from your router to the monitor, which then passes the network connection to your laptop via the USB-C cable. This eliminates a separate ethernet adapter when docking a laptop that lacks a native ethernet port.
