Just recently purchased a 2018 Chevy Tahoe premier with the RSE package. I’m having an issue with the HDMI resolution when trying to hook up an Apple TV or Roku device. The resolution is not going any higher than 480. I’ve seen folks on the forum having this issue but I’m not sure what the fix is. I’ve got to believe that the HDMI port will allow 720 or 1080, especially for a 70,000 vehicle.
