I will have to remind you of the importance of an IPS monitor (as I was recently reminded of myself).
And what is that?
I have 3x P2310H in landscape and they're perfectly fine.
I think the P2310H keeps going out of stock due to all the eyefinity users grabbing it as the perfect DP monitor. It took mine 2 months to ship back in december (got it in Feb.)... and a lot of eyefinity users I spoke to were also waiting on this monitor or already had it.
i managed to get 2 of the dell monitors, scan got them back in stock, is the resolution that windows shows (6048*1080 rather than 5760*1080) because of bezel correction? also is there a firefox addon to make it open on only one screen or make it open an instance on each screen?
Yes that's bezel correction. You don't need a firefox addon. Use hydragrid.
