CES 2021: Dell introduces 40-inch ultrawide monitor with 5K2K resolution UltraSharp 40 comes with an ultrawide aspect ratio of 21:9 thus more viewing space than normal monitors. Jan 12, 2021 18:29:35 IST Dell launched its ultrawide curved monitor the UltraSharp 40 at the CES 2021. The 40K curved WUHD monitor is the world’s first 40-inch ultrawide curved monitor to offer 5120 × 2160 resolution or 5K2K (WUHD). This monitor was part of a series of displays featured by Dell at the prestigious annual event. UltraSharp 40 or "U4021QW" comes with an ultrawide aspect ratio of 21:9 thus more viewing space than normal monitors. Its pixel resolution of 5120 × 2160 takes it to the level of a typical 4K screen but more accurately, it is around 140 pixels per inch (PPI). Thus, Dell is marketing the product for those who want higher resolution on a wider screen.
