Been using my Iiyama ProLite 431SB for the last couple of weeks. My first LCD and I am extremely pleased. Really bright, to the point of having to turn it down in a dark room. NO dead pixels on arrival, none since. Really nice design (none of the awful mix of silver and black just a deep black), really sharp screen. As you'd expect integrated speakers aren't up to much except system sounds. I've not tested out its 16ms capability with any games yet but will do shortly. As to how they compare with the others you mention, I don't know sorry.
