Hello all, I bought my first ACD 9 days ago and now I'm on my third one! They've had varying problems but the 2nd and the 3rd have been fairly similar. On a white background there is a definite colour gradient from a slight pink hue to white horizontally. I've tried calibrating, changing between graphic cards on my MBP but nothing has helped. The problem on the 2nd display was slightly different as there was a gradient from green to pink diagonally and because of this I've ruled out the problem cause being the MBP. This issue is driving me nuts! If someone could shed some light or have any possible solutions I'd be extremely grateful.
