Thanks, that's useful. I'm going to study the code a bit to figure out where
these extra modes are coming from exactly. They're not in the EDID explicitly,
but there's various logic to add various extra modes based on ... complex
conditions.

Hm, ideally they should have letterboxes on top/bottom in those cases. I'll
have a look at the logic that does the full aspect scaling, it may be
determining width/heights incorrectly.
