I've noticed that in dark scenes there is a narrow band about an inch wide running total height of display, about mid position, that does not go as dark as the adjacent area and has a faint shimmer. It's as if the pixels are not able to turn off and it looks like noise. I've run the display test and no issues but the test image is bright and full colour. The band is noticeable to others and I've checked signal strength, high 90s, but quails low. The other areas of the display do not show same issue despite the scenes causing the issue moving across that area. All under guarantee but explaining this may be an issue. Has anyone else had this problem?
