I recently purchased a Roku 4k TV and for whatever reason the picture quality on NETFLIX, HULU, AND DISNEY+ are all very poor. The screen is pixelated and spotty. THis doesn't happen on all Netflix shows, but most, and it doesn't happen at all on Prime Video. I have tried everything to fix the picture quality from updating the apps and resetting the tv and the apps as well as my wifi router, but nothing seems to work. HELP!!!
