Hi all , bit of an update with this , I've set the fire tv cube 3 to 2160p 50hz and I've tried smarters and xc app and both apps playing 50hz (25fps or 50fps) play fine, play anything U.S and it drops frames because it's 60hz in U.S , fire tv cube 3 auto resolution default is 60hz ! Set cube to 2160p 60hz and U.K drops frames but U.S is fine , now I tried the cube on my Sony 32" tv and it plays everything fine on 50hz and 60hz set to auto resolution , on my main Samsung tv that's when all the issues start , I've tried MX player and vlc and they don't help . I do have a 4k max fire stick and that plays the same content on my Samsung tv set to auto resolution without issue but the cube won't, Any ideas ?
