I understood what you mean ., but I repeat that I think himedia must change function based on HZ of TV. I don't say only for me but also for people that wants to buy Q10 Pro having a simple HD TV. It's like saying that you can't play with PS4 or XBOX because your TV doesn't suppor it. I find ridiculous that a player of 40 Eur can reproduce perfect a video and a player of 180 Eur not. As Mount81's wrote: "But I agree in some level, that this should be an expected featrure, regardless if it's labeled -also- as a "4K media player", since it is still a Media Player, that should have this feature in it's basics." Anyway next two weeks I'll go at my parents home and I'll test the box on their tv full hd that is more recent instead of mine.
