Looking at a screen for long hours can be quite tiring for the eyes, but it doesn’t have to. The new 27’’ iiyama ProLite E2791HSU is big enough to make sure you can clearly see every detail and it comes equipped with technologies to help keep your vision intact. The panel backlight is flicker free and the blue light reducer function limits the amount of blue light emitted by the screen. VGA, HDMI and DisplayPort inputs along with a USB hub assure broad connectivity options. As the monitor offers 1ms response time and supports FreeSync technology, it can serve not only as your workplace companion, but also to play games and watch movies.

HAS + PIVOT
With a height adjustable stand you will create an ergonomic work posture and position that meets all health and safety requirements. This will not only prevent any health issues but will also increase your productivity. The pivot function allows the screen to rotate from landscape to portrait orientation. This functionality can be useful if the application requires more height than width.
