I'm confused. When I set my NVidia card to output RGB, then the F8500 HDMI level must be set to Low to show blackest blacks. When I set the card to output YCbCr, the HDMI level is grayed out at Normal, and blacks look the same as RGB with Low setting.

Doesn't this contradict what you said above?

no that means your video card is sending black at 16 and white at 235 over hdmi.

I personally use the particular EODIS3 with all the HCFR (3.A single.6) computer software to calibrate my EPSON TW-9200 projector (5030UB). I??am through Germany and in a German born AV forum you will find a few reports this combination (EODIS3 as well as HCFR) leads to the color red will be measured to be able to lower which this kind of brings about a reddish photo.

Let me see if I get what the implications are.

The PC is an RGB (0-225) device. When using RGB over HDMI, it must be mapping 0-255 to 16-235 before sending, losing color resolution. This would not affect Blue Ray video (from the PC) which is already only using 16-235, but the Blue Ray player must map 16-235 to 0-255? The loss of color resolution would possibly be visible with photographs or other static content as banding or something.

When using YCbCr over HDMI, the PC is again mapping 0-255 to 16-235, with same implications as above.

Is that correct? BTW I couldn't detect a significant difference in HCFR between the two settings (RGB/Low vs YCbCr/Normal).

That will happen if you are not using an appropriate calibration for your display type. I could locate no credible reports of ArgyllCMS/HCFR id13 measurements being less accurate than with any other software. If anyone has a reproducible example of such a thing, then they should bring it forward.

Some video cards scale everything over HDMI to video levels 16-235 so the rendering software (MPC etc.) will have to expand blu-ray to 0-255 first to end up with correct output this way. A better situation is to force the video card to leave the levels alone when outputting RGB over HDMI, that way if you choose to render at video levels or full RGB there will be no scaling in the video card and no possibility of banding. This is the preferred HTPC set-up.

If you set the card to output YCC it will also scale everything to video levels with the possibility of banding.

My preferred calibration set-up is HCFR 16-235 + video card passthrough (0-255) + display set to RGB limited (low).

Hey, can't get my saturation's any better on my 64f8500.
Using oppo-103d set to 4:4:4
GDC disk with 10% APL and hcfr set to 75/75
Cell 17
Contrast 95
Brightness 49
Sharp 6
color 59

The last pic shows saturation sweep using 100/100 and Primary's and secondary's using 75/75.

Anything I can do to improve it? Thanks

It looks great. If you're worried about the numbers, you need to run everything with preferences back to 100%/100%.
Just expect your numbers at 100% to be worse than your numbers at 75% (which is fine).

Looks darn good to me. How are the two skin tones on the color checker patterns and overall average? If they are a little hot you might back off the color control a couple of clicks and/or play with the flesh tone setting to tweak those (mine ended up at +3).
