Report Adding support for Nvidia Shield TV in General Questions Posted November 20, 2018 Hi folks, need some help optimizing my setup (Shield TV/Flirc/Harmony 900). I just replaced my Nexus Player with a Shield TV. I had my Harmony 900 working perfectly with my old setup and it's working with the new one but the lag is just horrible on the Shield. I had no lag with the Nexus Player so I can't figure that out. I've played with adjusting the response time settings in the remote but that hasn't helped. FYI, with the Harmony 900 I have to use the old desktop software. Do you think this is a remote issue, Shield, or Flirc?
