{"slug":"best-office-monitor-under-400","title":"Best office monitor under $400?","question":"What is the best office monitor you can buy for under $400?","verdict":"As of 2026-07-01, ChatGPT, Claude and Gemini collectively rank ASUS ProArt PA279CRV #1 for office monitor under $400 on ModelsAgree by aggregate score. The models' case: Factory-calibrated 4K IPS panel with 99% DCI-P3 color accuracy, a versatile 96W USB-C power delivery hub, and an excellent ergonomic stand. The models' main caveat: Upgrade the refresh rate from 60Hz to 100Hz or higher for smoother desktop navigation. The strongest alternative is Dell UltraSharp U2724D — 27\" QHD IPS Black at 120Hz hits the sweet spot for office work — sharp text, smooth scrolling, excellent contrast and color accuracy, full USB-C dock. Not unanimous: ChatGPT picks Dell Pro 27 Plus P2725QE; Claude picks Dell UltraSharp U2723QE.
