{"slug":"best-4k-monitor-under-800","title":"Best 4K monitor under $800?","question":"What is the best 4K monitor you can buy for under $800?","verdict":"As of 2026-07-01, ChatGPT, Claude and Gemini collectively rank ASUS ProArt Display PA279CRV #1 for 4k monitor under $800 on ModelsAgree by aggregate score, though no single model picks it first. The models' case: 27\" 4K IPS with 99% AdobeRGB / 99% DCI-P3 and Calman factory calibration for genuine creator-grade color, 96W USB-C, and a usually-sub-$500 price that makes it the best. The models' main caveat: Add real local-dimming/mini-LED so HDR is more than a token VESA DisplayHDR 400 badge. The strongest alternative is Dell UltraSharp U2725QE — 27\" 4K IPS Black panel with class-leading contrast and deep blacks, factory-calibrated near-100% sRGB plus excellent uniformity, built-in 90W USB-C. Not unanimous: ChatGPT picks MSI MPG 321URX QD-OLED; Claude picks Dell UltraSharp U2725QE; Gemini picks MSI MPG 272URX QD-OLED.
