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
Can the LG 34WQ75C-B charge my laptop through the USB-C port alone?
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.
What does the built-in KVM switch actually do, and how does it work on this monitor?
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.
Is the 3440×1440 resolution sharp enough at 34 inches?
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.
Does this monitor support HDR gaming or video?
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.
What is the LAN port for, and why does a monitor have one?
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.
