Guys having a problem with the firestick 4k on my 4k tv. The picture quality is really poor running iptv trough vivid media app and smart iptv app. Perfect picture on the smart iptv app just trough the tv itself but when running both apps with the firestick the picture quality is poor? Anyone else had this problem and solved it? TV is samsung nu7300. Tried different settings on firestick in display but as i say picture quality is poor?
