And for the record, this is his other TV (available at the same paste
url as above):
Video data block
VIC 16 1920x1080@60Hz (native)
VIC 34 1920x1080@30Hz
VIC 32 1920x1080@24Hz
VIC 5 1920x1080i@60Hz
VIC 4 1280x720@60Hz
VIC 3 720x480@60Hz
VIC 2 720x480@60Hz
VIC 1 640x480@60Hz
Extended HDMI video details:
3D present
3D-capable-VIC mask present
3D: Side-by-side (half, horizontal)
3D: Top-and-bottom
3D VIC indices: 2 4
VIC index 0 supports side-by-side (half, horizontal)
VIC index 1 supports side-by-side (half, horizontal)
VIC index 2 supports side-by-side (half, horizontal)
VIC index 3 supports side-by-side (half, horizontal)
VIC index 4 supports side-by-side (half, horizontal)
After some more conversations with Alastair, it sounds like what's
actually going on is that it's just the frame-packing modes that
aren't working, but all the side-by-side and top-and-bottom modes from
the "mandatory" list work. At this point, I'm more inclined to believe
that there's an issue in the nouveau implementation for frame-packed
modes. But it could still be the TVs themselves that don't support
that at all.
