My d800 clusters boxes of 8x8 pixels in every Image. This makes it look more like a puzzle than a picture. We even reproduced this at Nikon HQ Switzerland. After two days they told me this was normal behaviour and a fault of my viewer Software - But its even visible on the LCD of the Camera itself. Could any kind soul please hit me with a bowling pin, if I didn' get a thing right or tell me if you had the same experience respectively how to convince Nikon to fix this issue?
Any help is appreciated by an absolute newbie.
I use win 64 with DxO 7.5.1, Lightroom 4.1 with Camera RAW 7.1.
