This screen look like it as very tick side and would not be good for a multi-monitor setup... Well you are dead wrong !!!
Take a look at those Disassembley Instrucktions:

The trick is that after removing the plastic cover around your monitor you can still screw back the stand right back in the skeleton of the monitor and it looks very awesome !!! and you will end up with a 1cm side screen... for a really cheap price...
