h4d-40 lcd question

[superswift]

hi i just got a h4d-40. super stoked, but i have a question im hoping another h4d owner might be able to answer.

when i shoot any underexposed image the lcd preview screen comes up with a strange line right down the middle of the image. has anyone ever seen this? and what might it be?

heres a couple pics of it

I think every h4d-40 have this. When the picture is underexposed, then you can see the effect from the "double readout" of the sensor. lg, rem

It happens with H4D-50 too.

My assume is because underexposed, i hope Hasselblad find way to solve the problem.
