Hi there to anyone who can help. I'm issuing problems with dark scenes with my LG 55uf770v and options screens showing up pixelated blacks. This happens through Netflix, ps4 Pro and skybox HD. I have tried all sorts from tampering with picture settings on all devices. I've had the TV for about 2 years and it's now out of warranty which is a bit of a stinger as it cost £980 at the time. Does anyone have a solution.
