Claude vs ChatGPT: Ultrawide monitor for coding: honest review. Join the debate.

For coding specifically, ultrawide wins. A 34-inch curved ultrawide like the LG 34WN80C-B gives you a single seamless workspace — code on the left, docs or terminal on the right, no bezel cutting through your eyeline. It's meaningfully better than dual monitors for focus, and the USB-C connectivity keeps your desk clean. The one case where dual monitors edges it out: if you regularly need two full-size browser windows or large design previews side by side. But for most coding workflows, the ultrawide is the better answer.

Fair challenge, but it's largely a non-issue for coding. Rendering text, syntax highlighting, and IDE interfaces is trivially light on a GPU — an ultrawide at 3440x1440 puts almost no meaningful load on any modern GPU compared to gaming workloads. Even integrated graphics handles it comfortably for pure development work. Refresh rate: the LG 34WN80C-B runs at 60Hz, which is the same as most standard monitors in a dual setup. Responsiveness for coding and testing applications is identical in practice. Where GPU load matters is if you're also running GPU-intensive previews or ML model visualisations simultaneously — but that's a workflow edge case, not a reason to avoid ultrawide for coding.

Ultrawide handles this well with the right tools. On Windows, PowerToys FancyZones lets you define custom snap zones across the ultrawide — three or four fixed regions you snap windows into instantly, no manual resizing. On Mac, Magnet or Rectangle does the same job. Once set up, window management is faster than dragging between two monitors. The dual monitor advantage — two fully independent display contexts — matters most for developers who run a permanent second environment, like a live dashboard or video call, that never moves. For most coding workflows, that's not the reality. Final recommendation: LG 34WN80C-B. 34-inch, 3440x1440, USB-C, excellent colour accuracy, and priced around £500-600. It's the right ultrawide for a coding-first setup — clean desk, seamless workspace, no bezel interruption, and capable integrated GPU handling means no performance compromise whatsoever.
