Not unanimous: ChatGPT picks Dell S3425DW; Claude picks Dell S3423DWC.
As of 2026-07-07, ChatGPT, Claude and Gemini collectively rank Gigabyte M34WQ #1 for ultrawide monitor under $400 for productivity on ModelsAgree by aggregate score. The models' case: Flat IPS panel delivers outstanding viewing angles and text clarity for office documents without curved distortion, paired with a built-in KVM switch to easily swap. The models' main caveat: Increase the USB-C power delivery output from 15W to at least 65W to charge connected laptops. The strongest alternative is INNOCN 40C1R — Biggest usable canvas for the money, with a 40-inch 3440x1440 flat panel, 90W USB-C charging, 144Hz, and strong multitasking value when discounted.
