I have a lg 55ub820v. I am happy with the picture quality when streaming but when I okay a bluray ( either ps4 or Xbox one) the picture is a bit grainy and doesn't look great at all. I understand they are probably not the best bluray players but the picture really should be better. It is more like 720p rather than 1080p let alone the TV actually doing any upscaling. I've played with the settings but no luck. Am I missing something? Any ideas?
