The verdict

Not unanimous: Claude picks Dell S2721QS; Gemini picks Dell S2725QC.
As of 2026-07-01, ChatGPT, Claude and Gemini collectively rank ASUS ROG Strix XG27UCG #1 for 4k monitor under $300 on ModelsAgree by aggregate score. The models' case: 4K 160Hz IPS plus 1080p 320Hz dual-mode, fast 1ms response, strong VRR support, sharp 27-inch pixel density, and rare gaming performance at $299. The models' main caveat: Add real HDR hardware with local dimming. The strongest alternative is Dell S2721QS — 27" 4K IPS panel with accurate factory color, a genuinely ergonomic stand (height/tilt/swivel/pivot) that's rare at this price, and Dell's reliability. Not unanimous: Claude picks Dell S2721QS; Gemini picks Dell S2725QC. Source: https://modelsagree.com/best/best-4k-monitor-under-300 (modelsagree.com, CC BY 4.0).
