The ICT spec doesn't allow the turning off of outputs, only constraining the resolution. I was wrong about the resolution, it just has to half the 1080 lines, to 540, so not quite as low as DVD's 480, but definitely not HD.

It's the player which has to do the resizing (which is why it was kept a simple 1/2 so no complicated scaling has to be done).
