I'd like to stay away from the TN panels. It's my understanding that the image quality goes right out the window in portrait mode.
I am interested in the LP2275 however. This is the first mention I've seen of it, of course I have been looking for ips but pva should give just as good angles.
Let me ask this, would running 3x lp2275w and 2x 2209wa be viable.
They're both 22" 1650x1050, my concern however would be mixing the ips vs pva screens and having different input and video lags between them. This would however give me the 3x native dp screens required, and save roughly 300$ total.
3x lp2275 = 1050
2x 2209wa = 420
It puts me square into the price range of the 5x NEC's but gives me the 16x10 resolution that I'd prefer. The only concern I have regarding the lp2275 is this:

It appears, although I admit it's tough to tell, that the base extends a few mm's past the sides of the screen in portrait mode. That would mean either dropping more cash for mounts, or having alignment issues.
