Dell UltraSharp U4025QW is the biggest productivity ultrawide on this list. Dell lists a 39.7-inch IPS Black panel at 5120 x 2160 and 120Hz, which gives 140 pixels per inch, so text looks closer to a 4K monitor than to a 3440 x 1440 ultrawide. Native contrast is 2,000:1, brightness is 450 nits with a 600 nit peak, and Dell lists VESA DisplayHDR 600 and 99% DCI-P3. The 2500R curve is gentler than the 34-inch models. The hub goes further than the U3425WE: the Thunderbolt 4 upstream port charges at up to 140W EPR, enough for large laptops, and the monitor adds 2.5GbE Ethernet, a KVM switch, a downstream Thunderbolt 4 port and two 9W speakers. The warranty is 3 years limited with Advanced Exchange Service. The cost is the drawback: Dell.com listed it at $1,749.99, down from $2,399.99, when we checked. We compared documented features and published prices only.
