I've pretty much ruled out the 23". I don't want to go smaller and I'd be giving up 1" of vertical height even with the added 1.5" width. So I'm looking for a 24" whether it's 16:10 or 16:9. So far I'm looking at the Dell U2412M, which is an eIPS 1920x1200 display or the ASUS VS248H-P. Everywhere I look the reviews are pretty much the same for both. The only complaint I see about the Dell is the anti-glare coating seems to bother some people. The ASUS being a TN panel has the typical viewing angle issues, and some complaints about the stand (which won't effect me as I'll be mounting it on an arm). I hope this monitor will power up tomorrow because I doubt I'll make up my mind tonight.
I'm still slightly leaning toward the Dell because of the higher resolution. I don't think the anti-glare coating will bother me. The monitor I had before this one was an anti-glare matte screen and sometimes I wish this one had it instead of being glossy.
