Expert review by : Mike Jennings (

BenQ BL2420Z


This no-nonsense business monitor doesn't have the kind of flashy design that'll help it stand out in a stylish office, but it makes up for its lack of style with a solid range of features.

Ben Q BL2420Z


This is an LED backlight monitor that is kind to the eyes and also is part of their value series. So what does this have to offer that will tempt you away from whatever you are currently using.

The Ben Q BL2420Z is available with free delivery.
