About the LG 34WQ75C-B

The 34WQ75C-B has a 34.14-inch IPS panel with a 3800R curve and a 3440 x 1440 resolution. Refresh rate tops out at 60Hz with a 5ms response time (GtG at Faster). LG gives typical brightness as 300 cd/m² and typical contrast as 1000:1, with 99% typical sRGB coverage. HDR10 is supported, but the LG page lists no DisplayHDR certification, and there is no FreeSync, G-Sync or other adaptive sync.

The back panel has one USB-C port that carries video, data and up to 90W of power to a laptop, plus two HDMI inputs and one DisplayPort 1.4. There is an RJ45 network port and a built-in KVM switch, so one keyboard and mouse can move between two computers. USB-A is one upstream (2.0) and four downstream (two 3.0, two 2.0). A 3.5mm headphone output sits alongside two 7W MaxxAudio speakers.

The One Click Stand tilts from -5° to 20° and raises the screen by 0 to 110mm. It does not swivel or pivot. The monitor weighs 8.6kg with the stand and 6.7kg without, and the stand-free body fits 100 x 100mm VESA mounts. LG lists USB-C, HDMI and DisplayPort cables as included.

What owners report about the LG 34WQ75C-B

Owner feedback we could find for this exact model is thin. The one long-term account we found is from an owner who has used it daily for about six months for coding, work and video, and reports no faults.

That owner likes the whites and general picture quality, and finds the curve keeps the screen edges easy to see. At QHD, Windows scaling can stay at 100%, where their earlier 4K screens needed more. They run two windows side by side, sometimes three.

Complaints are small. The monitor is heavy, so setting it up needs care. Moving down from 4K felt like a step back at first, and the owner has never used the built-in speakers. They also note an ultrawide adds little if you mostly use one app full screen.

Who the LG 34WQ75C-B suits

Buy it if you work from a laptop and want one cable for video, charging and wired network, or if you switch one keyboard and mouse between two computers. It also suits anyone who keeps several documents or windows open at once.

Look elsewhere for gaming: 60Hz with no adaptive sync is the wrong fit, and the Dell UltraSharp U3225QE runs at 120Hz. If you want sharper text, a 4K screen such as the LG 27UP85NP-W is a better fit. The stand does not swivel or pivot, so a monitor with the full ergonomic stand, such as the AOC Q27E3UMF, suits changing desk layouts.

How we score it

Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 17 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
