Third one is IPS and in that regards should be the most expensive but it's the cheapest so I'm questioning it's quality.

first and second if just compareing specs are almost identical and the price difference is around 10-20€.

And advice, or which one would you choose?
Purpose of the monitor:
- reading, working
- multimedia + movies
- games

Edit:
I also have ps3 so I would like to connect that to the monitor and to play 3D on it if possible.
