HiIn the winter of 2016 I bought a Beovision Avant 85 (and Beolab 5 and 18) from B&O retailer in Sweden. Since then I discovered that the entire screen has vertical stripes which are most visable during camera panoramic movement or when there is one bright colour on the screen or parts of it (see attachment) I have tried with different sources and with adjusting the settings but nothing has worked.
In my opinion the screen must be defected. I have contacted B&O HQ in Denmark but they refuse to help!! They give the following response:
Beovision 7-55 Mk2, Avant RF 28, Beolab 9, Beolit 15, Beoplay A1/A2, Beocom 2, Beotime, H3 ANC/H8/H6/H2, Form 2, Beoplay A3, Beovision 5-42 connected to a DVD1
I still would like to see better pictures of the issue. Many times it looks exaggerated through a camera and also some issues due to the backlight is unfortunately impossible to make anything about. By the way, the new screens (55 and 75") are global dimming = just one big zone so there's a change the issue is less apparent on the new models but they would then lack the possibility to dim better at dark zones without making bright ones dark. The 85" is still 2D dimming though.Here is an example of how clouding might look through a camera (even my Avant that looks nice shows signs of clouding in the corners through a camera) http://screen-uniformity.wikia.com/wiki/CloudingI don't want to stand on anyones side here but I think that A) the evidence (the picture) is really bad and B) it is very hard to say what the issue looks like IRL and C) the issue might be a part of how the screen technology works - not much different than any other manufacturer would also have in their local dimming sets possibly. And D) There is other issues as well, the algorithm for smoothing (interpolating) frames to make them more fluid (step up from 25 fps to 50/60/100/120hz) creates extra frames that the software cant make properly in all situations, especially panning - so on any Avant (or any TV with this kind of tech) there will be some strange glitches in certain situations (you can also turn the feature off and get a more choppy video).
