LCD MONITOR for PS3, questions

I'm pretty much a noob when it comes to technical specs and what to look for. But I know if I want to play a PS3 on a monitor it needs to be HDCP. With that being said I came up with this one.

If any of you have/are using a monitor how does it look. I've heard sometimes the picture will stretch. Will this be the case on the one listed?

yes it will stretch, either you get a 1440 x 900 and run 720p or something more than 1080 and run 1080p
not saying that 1050 will necessarily not do a good job, it depends on the scalar in it

i'll leave the rest to those who own a dell monitor, i know nothing about them
