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.
