You are right. When I tested, I tried to create edid, but first of all, 24fps>24fps 30fps>30fps with cvt rb standard, but 60fps still output 30fps. The level used the default ICVFX LEVEL.
And when full standard was used, 24fps> 12fps 30fps>15fps 60>30fps all fell by half. Before edid creation, 60fps was possible, but now it’s not only 60fps. The more you do it, the more it feels like a labyrinth.
