LED Dell UltraSharp Curved U4919DW 49″

“The first dual QHD 49-inch monitor in the world will help you perform better. For a smooth, ultra wide viewing experience, the large screen with In-Plane Switching technology is equivalent to two 27-inch dual QHD displays without the bezel in between.
Picture-by-Picture enables you to view your information from two distinct PC sources (PBP). Free from the distracting borders, this feature divides the screen into two sides.”
