In order to test the problems in my signature I tried the different resolution modes only yesterday, and it worked. (That is aside from the bug in my signature error tivo then ignores and picks the lowest resolution or 2160 if you have that picked. But the 1080i setting itself is saved)
Which firmware version are you and I'll compare tomorrow.
---------------------------------------------------------- 2011 TiVo scaling bug
Did anyone get to the bottom of this? Is it a confirmed bug, as I have the same issue.
I have a HDMI splitter that goes to a 4k capable TV, a 1080p capable TV, and a HDMI > Scart converter for distribution around the house on Coax (via a RF modulator).
To try and keep everything stable I have set the Video Output to be 1080i. Everything else is unticked.
This works to an extent but only if the TV's are on when you set this setting. If for example I turn all the TV's off except the 4k TV, then I start to hit problems. The 4k TV on it's own seems to invoke the v6 box to change the Video Output setting! I go into the menu and it's set at 2160p, on its own accord. The 1080i setting is lost and I get no output on the other TV. The only way to fix it is to manually change the Video Output setting all over again to 1080i. This will only work until the next time I happen to turn TV's on/off in a way that means the V6 box changes the setting again to 2160p.
I have tried other combinations of resolution on the output setting but it still wants to reset to 2160p only.
I have tried a different splitter (a 2 output one) with just the 4k TV and the 1080p TV on it, but the same thing happens. The 4k TV always seems to manage to change the v6 box video output setting.
Any advice? I did think about purchasing a different splitter that had a top capability of 1080p.
