I connected it to my Amazon Firestick 4K Max. It got delivered upfront and got time to set it up. Picture quality is good, not too bright but enough brightness to view picture. 4K and FHD content looks good. Sound is also good enough for my room. Connected to my QAcoustics via Optical cable and output is too low. I had to crank it up to -10db for decent sound. Need to change the optical cable and try again. I will post some images soon.
