Help needed, brightness problem

[dellight]

Hey guys, i just bought 3x Benq GW2250HM full HD monitors for my 7970.

The problem is:

connections:
1. DVI->DVI
2. DVI->DVI to Mdisplayport adapter->minidisplayport
3. DVI->DVI to Mdisplayport adapter->minidisplayport

I set up eyefinity, but my middle screen is a lot brighter than the side ones!!
I tried calibrating the middle monitor but it didn't get any better...

what to do?..

thanks

try changing middle Monitor with left Monitor!
If the middle Monitor is still brightest then its a viewing Problem.
if the left Monitor is the brightest its either wrong settings or production fault.
