One of the questions I asked Nikon at Photokina more than a week ago was this: how the heck do you get the promised uncompressed HDMI out of the camera? The D600 doesn't have the same Advanced options on the HDMI menu, meaning that you can't really control overlay or size of the output. As many people are beginning to notice, it's not obvious how you get clean HDMI out of the D600. Indeed, hooked to all three of my HDMI systems, I get 95% output, which isn't exactly right.
Nikon promised to get back to me. So far: nada.
