2209WA closest replacement for P2210

Hi, I have 2 Dell P2210 monitors and am looking to add a third monitor.  My setup is a year old and I was hoping to add the same type of monitor.  It seems that the 2209WA is the closest replacement for the P2210 based on the resolution and the stand / bezel appearance.  Does anyone have any first hand experience with this?  I don't want to end up with vastly different monitors in my setup as I find it a bit of a visual distraction.

My only issue with the P2210 is that the screen fades towards the edges depending on where I am sitting (which is probably too close!).  I had originally been planning 3 monitors in portrait mode but the screen fade out means that you can't see all the screens from one position.  (For some reason the fade out effect is less pronounced with the monitors in landscape mode.)

I am sort of hoping the 2209WA doesn't have this same problem, does anyone know?  Is there a way to measure actual viewing angle on monitors?

Thanks
