Predator X27 Light banding due to fald

ChrisKar

Hi to all. I would like to share something about the predator x27 and maybe if noticed by Acer could be fixed in future firmware updates. When and only when fald is on, in mostly dark uniform content - colors there is slight vertical and horizontal banding visible  which is clearly the result of the underlying Led grid. A note here. If you go full screen with the solid color banding disappears probably because the local dimming algorith changes the way that the entire panel is illuminated. You have to have a solid color covering portion of the screen and not 100%  in order for the banding to appear. This is not DSE effect or uniformity problem inherent to panel itself. When you turn off fald banding completely disappears. This exact sort of banding exists also in some fald tv sets and in many cases it has been fixed or at least improved with firmware updates that improved the local dimming algorith. So if anyone is reading this post from Acer can you guys check this out? I would not even bother about it but the thing is that you can actually notice it in games when you have panning shots for example when looking to the sky (solid uniform colors) .
