I just checked my "Video" options and 1080p was not checked. I have a Sony EX700. The 1080p also has "(24fps, pass-through only)" next to it. I don't know if that means 1080p/60 is not supported. I then ran the video test. The result is now ALL boxes are checked. I can't speculate why it wasn't checked before, but I have changed cables. I also don't have a native mode on the TiVo that I could find. I seem to remember setting 1080i at one time to fix the output at 1080i before I got my cable card. No conclusions, but I would run the video test again.
BTW, the TiVo feeds a Yamaha AVR set to "Pass-Through".
Hi Joe, I just ran the video test again and the Tivo still says: 1080p (not supported). The Tivo selects the 1080i format as optimal and there is not option for selecting 1080p.
I did also just play a YouTube 1080p video through the Tivo. It did play, but the Sony TV said it was 1080i formated. It was interesting to see that the Tivo appeared to be sending the full 1920 samples x 1080 lines. I had a very clear picture will high detail. I forgot to mention to Kelson, that the Tivo tech did say that the Tivo would output the full 1920 x 1080 quality only if the programming material was 1080p. Also my Tivo is a Premiere 4 and my TV is a Sony KDS-50A2020.
