I have a Slingbox 350 streaming to the slingplayer up on a Roku and am only getting a max resolution of 1920x540. I have tried streaming from both an iPad and Android device with the same result. I have plenty of bandwidth >50mbps and get full HD resolution when streaming to a web client on the same network, so it's not a network issue. Is this a limit to the slingplayer apps for Roku/iOS/Android? Does the new chromecast support have the same limitations? Is the only way to get full HD streaming to my TV through a connected PC?
