L-2442WD issue...

[weird_dave]

I just got a DGM L-2442WD monitor, elsewhere unfortunately. When I view it straight on, the top is dark and the bottom light, if I stand up, it's uniform. I've asked to RMA it but am now concerned about buying another LCD. Any thoughts?
How do I add a picture? Then you could all see just how bad it is.....

Hopefully this will work....

I did take the plastic cover off, just left the tape on around the sides.
I made the screen green to show up the problem, blue works well too.
White looks kinda grey at the top.
I went to a local shop and saw the iiyama prolite 2607wsv, and it suffers exactly the same problem!
I'll have to try and find the other thread that mentions this problem.
This leaves me wondering what monitor to go for....
