Excellent monitor....
In my opinion, the value for money is excellent. There's no need to worry about installation, and compared with two separate screens, you save on the mess of cables!
Just beware of the weight of the screen when you're handling it.
For office use, there's no problem at all: you can work with four windows displayed simultaneously, all of which are a good size and easy to read.
In my opinion, this screen is perfect for multi-window use.
