Recently, the picture quality on the Q90T appears grainy (a lot more noise). This seems to be the case with cable on hdmi and streaming. It seems to be associated with older content. However, up until recently that same content was clearer. On new content (e.g., live news) the picture isn't as sharp as before. I don't know if its associated with the recent 1403 firmware update. But that is the only change that has happened (no change to picture settings).
Has anyone else noticed any change in picture quality since the recent update?
