And though it seems to me that the latest firmware update only served to improve overall clarity and transparency; even off angle. My set has 9 months of use. It may be fair to say that as the dynamic artifacts are reduced, you will start to see other remnant artifacts, that were there before, but just not so noticeable. Also , if these vertical bands are only seen with camera motion, it could be the sets image retention artifact. I see that if there are lots of vertical details and the camera pans sideways quickly. But in still shots, the transparency is breathtaking to me, especially nighttime wet road scenes. And I am only talking SD. For reference, I have the brightness on 17, clearness on 1. smoothness on 3. Color Temperature on Neutral. The only factory setting I have altered is color to 55. Contrast is set with the munsil disc, I believe it is on 90.
