Stylish ultra-flat front design makes the ProLite XUB2792QSU perfect for multi-monitor set-ups. The IPS panel technology offers accurate and consistent colour reproduction with wide viewing angles and the QHD (2560 x 1440) resolution means the XUB2792QSU can accomodate almost 77 more information on the screen than a Full HD display. High contrast and brightness values guarantee the monitor will provide excellent performance for photographic and web design, and the height adjustable stand ensures you can easily adjust the screen position to your preferences. It is a great choice for both multi-monitor Digital Signage and office applications.
