LG UltraFine 27US550-W 27" 4K UHD IPS Monitor, HDR10 White — Open Box

The LG UltraFine 27US550-W puts 4K UHD (3840×2160) on a 27" IPS panel with 178° viewing angles, HDR10, and 90% DCI-P3 color coverage — the kind of color fidelity photographers, video editors, and designers actually need. At 300 nits brightness with a 3-side virtually borderless design, it's a clean, distraction-free workspace whether you're editing in Premiere, coding two split panes, or running a video call. Whether you're upgrading from a 1080p panel or stepping into 4K creative work for the first time, 27 inches at this resolution is the productivity boost most desks are missing.
