Looking at a screen for long hours can be quite tiring for the eyes. But it doesnt have to. The new 27 iiyama ProLite B2791QSU 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 B2791QSU offers WQHD (2560 x 1440) resolution meaning the screen can accommodate almost 77% more information than a Full HD display. E-mail and excel will fit in nicely next to each other. The panel backlight is flicker free and the blue light reducer function limits the amount of blue, the most unfavorable, light emitted by the screen. The height adjustable stand allows you to easily adjust the screen position to make sure you are looking at it at the right angle. DVI, HDMI and DisplayPort inputs along with a USB hub assure broad connectivity options. And 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.
