Dell 2007FP monitor difference..

[dynamitetalks]

Hi.

I want a monitor setup with three screens..
My main monitor is a DELL U3011 and with a google search I found out that everyone was recommending to use 2 * Dell 2007FP on the sides of the U3011.

So I brought one Dell 2007FP REV A12
and now another used have appeared at the secondhand website I tend to use, but it is a
REV A02

I can read that from the REV 02, 03 and to 04 the panel is random either an IPS or PVA

So here is my question, do I just buy the REV A02 and hope it seems okay in comparison to the newer A12 or should I wait till a newer model comes for second hand sale and if how much newer of a model should it be or does it have to be identical and be an A12 version too?

Thanks and best regards
