well after a lot of reading of reviews, comparisons, and models specs i decided to go for the ASUS PA246Q. it seems superior than the others and as i dont plan on changing it until is broken i decided to go with this one. i was looking around for the Dell U2410 because i read that it was better than the U2412m but couldnt find so i took the Asus. Hopefully i will have it by Friday.
thank you all for the feedback
