reddeercity, I use a 60D for work, and I've looked up and down these forums, the ML wiki and the ML site for confirmation of uncompressed, clean, HDMI output, and it just hasn't been done. The best ML gets is a clean but cropped image. The output is a true 1920 x 1080, but the actual image is only 1620 x 1080, flanked by black bars on either side of the screen. It basically looks like you are watching an old TV show shot in 3:2 on a widescreen display.
So my point is that real, true, clean (sans black bars), uncompressed HDMI has yet to be achieved by ML. In early 2012, this article (
http://nofilmschool.com/2012/02/magic-lantern-unified-clean-uncompressed) came out, which might be what you're thinking of. Uncompressed, clean HDMI out is possible, it just hasn't been done yet. That is why I'm so excited that it's come to a sub-$2,000 camera that also happens to have a lot of other great features. Now if only they would send the audio through that same HDMI output...
