In low light greyish or blue content I notice White moving bands. I saw this on the native netflix app. When watching the same content on the nvidia shield I don't have these lines. So I don't think the issue is interference related. I paused the content in this video:
It is a little hard to see @Warshooter. Are these horizontal bands moving up the TV screen? Could we also take the full model code and current software version of the TV? Go to Home > Settings > Support > About This TV.
I made another video: https://youtu.be/Lw9zooTw-JM
Should be more clear.
Model code: QE75Q90TALXXN
Software version: T-NKMDEUC-1406.9, B0052200/B60101, BT-S
It are indeed bands that move upwards
