I have to give a nod to Denon with the inclusion of both HDMI and DVI ports. The whole DVI-HDMI chipset issue that causes loss of blacker than black is something to be concerned about with an HDMI only player, I can't remember if it's only for DVI -> HDMI or vice versa, or both. It is an issue that you need to be aware of though.
Of course, if you have HDMI on your display, then it's a moot point (;
There has been a significant amount of debate on this issue. And, I haven't seen a well-written conclusion that makes clear sense. In an effort to resolve the issue, I'd like document the conclusion I've formed. (Feel free to let me know if I've got it wrong)!
In another thread, a video cabler/designer confirmed that pin configurations are NOT the cause. In fact, he said there is a 1-to-1 mapping of the pins when using a DVI=>HDMI or HDMI=>DVI adapter (or cable). Additionally, I understand the HDMI specification to target standard 0-255 video levels. That means an HDMI input port should expect to receive these values. However, DVI was designed more as a computer interface (at least at the beginning). And, that means the narrower bit values (7-255) can be expected by some displays.
If you feed a 0-255 signal (standard video levels) to a port which only "see's" 7-255 (PC levels), you'll lose/crop below-black information. The result is that deep blacks won't be available. Conversely, if you send a DVI (PC) signal to an HDMI port, below-black information is displayed, but because it was already compressed (crushed) up into the values above it, some detail will be lost. This "crushing" means that fewer shades of black are retained. (Realize that a DVI PC signal will also look the same when fed into a DVI port).
My conclusion is that you need to investigate the video levels of your source device and your display device. If your source device does not send the full 0-255 range, you'll never get to see as much black detail. If your display device does not look for the full 0-255 range, you probably won't see the darkest blacks possible. Knowing these parameters should make it simple to predict how your display will react to a particular input device and/or cable conversion.
