LG 27UP850K-W UltraFine 4K review

LG 27UP850K-W is the 4K monitor to buy if you want good color and a USB-C connection without paying UltraSharp prices. LG lists a 27-inch 4K IPS panel with up to 95% DCI-P3 and VESA DisplayHDR 400 certification, so photos and video look richer than on a basic sRGB office screen. The stand adjusts for height, tilt and pivot, which means you can turn the screen vertical for long documents, and the LG Switch app splits the screen into custom layouts. LG.com listed it at $349.99 when we checked and offered a 2 year Premium Care plan for $1 until December 6, 2026. The product page we checked did not state the USB-C charging wattage in its key features, so confirm the figure on the spec sheet if you plan to power a laptop from it. There is no Ethernet port or KVM switch, unlike the Dell U2725QE. We compared documented features and published prices only.
