That guy told me, that strong BLB is "normal" And he has talked about problems which i dont have with my monitor (which leads to a motherboard replacement, instead of fixing the BLB with a new panel).
I've get a new XL2730Z from BenQ now, not because of the BLB, but because of two defect, shining pixels. I don't hope the new one has the same problems. So i don't have to let my anger free on the service hotline.
