4K UHD3840×2160 — 4K UHD — is a 16:9 resolution with 8,294,400 pixels. At this pixel count, you'll typically want OS display scaling above 100% for readable text.
4K UHD is four times the pixels of Full HD and the standard for TVs, streaming, and high-end monitors. At desktop sizes it usually runs at 125–175% OS scaling for sharp text, and driving games at native 4K remains one of the heaviest workloads you can give a graphics card.
