I currently am using a firestick to view my iptv service...everything works fine but when I try out the multiscreen feature with 3 to 4 streams going at the same time it begins to slow down the streams..making it not run smooth. I tried the app on my phone (note 9) and it worked flawlessly with 4 streams going. That being said..I need a box that has a better processer and can handle 4 streams at once. Was thinking of going nvidia shield..but..I only use it mostly for iptv and netflix or showbox and heard it was overkill for what I use it for. What do you guys recommend?
