The Dell Ultrasharp U3818DW is a 38-inch curved ultrawide screen suitable for using multiple windows at the same time. With the 21:9 aspect ratio and the 3840x1600-pixel resolution, you'll have more than enough screen space, and you can use different programs side by side. You could open your browser and work on a presentation without switching between the 2 windows. Thanks to the screen's curved shape, you won't have to turn your head as much, and you can see the whole screen at a single glance. Connect your desktop or laptop using the two HDMI ports or the DisplayPort connector, and connect all your peripherals with the integrated USB hub. This Dell monitor also provides sound with two 9W stereo speakers integrated in the screen.Note: For a 4k output, you need a modern laptop or PC with a fairly powerful video card. Make sure it has at least a DisplayPort 1.2, HDMI 2.0, or Thunderbolt 2 connection.
