The models' case: 27\" IPS 4K at ~$300 with built-in USB-C 65W charging, height/tilt/swivel stand, and Dell's reliable color accuracy and warranty make it the most complete value pick under. The models' main caveat: Bump the 60Hz panel to 120Hz+ so it competes with the gaming-capable screens at this price. The strongest alternative is Gigabyte M28U — 28\" 4K 144Hz IPS with HDMI 2.1, KVM switch, and ~1ms response lands near $450, giving console and PC gamers true high-refresh 4K that the cheaper. Not unanimous: ChatGPT picks MSI MAG 322URDF; Gemini picks ASUS ProArt PA279CRV.
