There is Dolby digital when you play channel like star or Zee you get Dolby digital logo and you feel the sound difference where their is no Dolby digital I have posted pic with Dolby digital of star plus hd channel only this is even you can select hdr but on diagnostic it say hdr format not supported I will upload video soon with setting and interface
So like xstream 4 , if you select 4k 60hz output, 10/12bit color space format not available, still restricted to 8bit and I was hoping for the picture settings (brightness. Contrast, saturation, sharpness) but sadly those are missing too
Red button is for recording, green button is take you to TV guide along with Epg, yellow button take you to sport channel and blue button take you to airtel special channel .
