Advertisements Hello, I recently received a Tivo Stream 4K for the holidays and have hooked it up to my Sony Bravia 4K XBR-49X900F TV. The problem I am seeing is that the Tivo 4K picture is no where near as sharp as the 2 year old Amazon FireTV 4K Cube I have previously been using. If I check the picture output on the TV while using each device, the Sony shows "3840x2160p 4K - 16:9 - Dolby Digital Plus" for both the Tivo Stream and Amazon cube. Both devices are using my home wifi and I checked the network strength on the Tivo Stream which says "Excellent". Ive tried watching movies and sports using both devices through the tv, swapping them out on the same HDMI port. and there is a big noticeable difference in the pictures. The football game and movies through the Amazon cube was so vivid, clear and bright, while the Tivo Stream was noticeably duller and colors no where near as vivid. I used the same HDMI port and different apps, and the picture output remained the same. Is this just normal? Is the Amazon cube supposed to give a better picture than the Tivo 4K stick? Or are there video settings which should be modified on the Tivo stick? I figure 4K is 4K, regardless of the streaming device so I am really disappointed as I have been a big Tivo fan since the early days, and love the Tivo Stream app. But lower quality picture would obviously be a deal breaker for me.
