Grab two of those AOC E2250Swdak monitors for under £160 from Dabs and enjoy a very decent multi-display set-up; that's what I'd suggest to any businesses who would like to enjoy a boost in productivity.
You will need to enter the code MEGA10a at checkout in order to cut the original selling price of the AOC E2250Swdak from £88.17 to £79.35 and the offer ends on 31 May at 23:59.
The display has a thin 18mm bezel and a fairly traditional design with a 1,920 x 1,080 pixel resolution with a 0.248mm pixel pitch, a brightness of 250cd/m^2, a contrast ratio of 1000:1, a 5ms response time, DVI-D and VGA connectors and a whopping three year warranty.
The monitor can only tilt and cannot pivot; it does come with a VESA mount which is always handy if you want to put it on monitor stands and it consumes only 32W when in use and a mere 500mW when in standby.
Interestingly enough, it does have a pair of tiny speakers (although you will need to connect a separate audio cable to get any sound out of it). AOC is the sister company of Philips and is owned by a Chinese company.
