IPS Monitor, 23" 1080p or better, for $250 USD

Hi I'm looking for an IPS monitor for about $250 USD to replace one of my old 19" TN.

It has to be 23" and 1080p or larger, with emphasis on image quality and not too slow for gaming.

The Dell U2312HM looks very good all round and is popular so I'm looking for something in it's league or better. I don't mind spending more for better image quality as long as it doesn't hit $300.


Any suggestions are welcome!
Thanks in advance! :)
