Advertisements This situation has happened twice in the past few months as I have bought two separate 1080p displays (one of which I returned). When swapping from one 1080p display to another, Tivo Roamio seems to revert back to 480p. The first time it happened, on my Panasonic ZT60, I was able to easily go into Roamio's Video Settings and change the output to 1080p. Now with my second 1080p display, the Samsung F8500, Roamio won't allow me to change to any 1080 settings. It will certainly DETECT that there is 1080i/1080p support, but will not allow me to choose the option when I try and save those settings. Anyone else having this problem? And while I am at it... What is the official Tivo setting for HD displays? Is it 1080i? Is it 1080p? Or is it 1080p Pass-Through? (I think those are the exact choices) Thanks in advance for the assistance.
