    I have my Roamio OTA running into a HDMJ matrix and a HDMI extender via Cat6 to a LG 4K TV.

    The Tivo will not let me select anything but 480i, or 480P. The other selections are grayed out.

    Everything connected to the Tivo supports at least 1080P, so what could be the issue?

    Test each resolution under the Tivo/Settings menu.

    How can I test them? I cannot select anything other than 480P.

    ALL of the others are grayed out, so it's not possible to select and test.

    What brand of HDMI Matrix?

    Sounds like the TiVo is getting incorrect information on the HDMI cable.

    What if you set the TiVo up separately from the Matrix and then reconnect it?

    I had this issue. All but 480 greyed out. Made for horrible menu guide graphics.

    What worked for me was going thru a setup, (don't recall specifics, sorry) and after the TiVo tests each resolution and selects them via check mark, but before moving on to next step, I deselected all but the 720p & 1080 ones.

    This has resulted in my Roamio outputting minimum of 720p, even if the show is in 480. YMMV.

    Edit: I found that I can press the up arrow key above the select key on my remote to cycle between 720p & 1080p & 1080i.
