The Dell UltraSharp U4919DW is the first 49-inch QHD ultrawide monitor to hit the market. Others with a 32:9 aspect ratio have a vertical resolution of 1080p. 
The result may be a wide, but concise user interface. But in the case of the Dell UltraSharp U4919DW, there are more pixels and a better viewing angle.

What makes the U4919DW very different from other 32:9 monitors is its dual QHD display with a resolution of 5120×1440 pixels. In addition to this screen resolution, the monitor features a 3800R curvature with support for 109 pixels per inch and 100% sRGB for much more accurate colors. Like any other ultra-wide monitor, it features HDMI/DisplayPort/USB-C support, as well as KDM (keyboard, video, and mouse) functionality.
Using the U4919DW's KDM, you can connect one machine via USB-C and a second via HDMI/DisplayPort with USB upstream. Of course, you can use keyboard shortcuts via Dell to manage both systems and their peripherals.
Dell says the UltraSharp U4919DW will cost $1,599, a price that doesn't seem that expensive considering what it offers.
