The iiyama ProLite LE5540UHS-B1 is a large format 4K display for displaying information and images. You hang it at the office, or in your company or school to show information in large dimensions and at a high resolution. The AMVA3 LED panel displays colors exactly as you intend them. With a viewing angle of 178 degrees, you can also see images when you're standing almost next to the screen. Because of the thin bezel, you only see the information that matters. You can use this screen for up to 18 hours a day, 7 days a week. This way, you can be sure that your screen will last throughout the working day.
