I tried to watch my 1080p videos through my hdtv using the stock gallery app. The reproduction was not fluid at all. Both sound and picture kept stuttering. There wasn't any problem with 720p videos. I know galaxy s4 can send 1080p videos via dlna without problem. If it isn't a snapdragon 600 issue, is there anything can do to watch my videos through my tv? A setting or another app maybe?
