Do you use a specific pixel format for the pattern generation? 4:4:4 or 4:2:2? I believe the F8500 is nattively 4:2:2 so that may be best. My assumption is you don't want to use RGB Full or Limited as the color processing would be done on the video card then.
Yes, you'll be doing yourself a huge favor by setting up the internal generator. Once you're set up to match your BD player's output, you are good to go. You'll want to use RGB full from the PC with raw output and set the generator to 16-235. I also suggest saving the MPEG version of the GCD disk and getting a player that will also match up with your BD for occasional non-HCFR generated patterns. I've found VCL Media Player to work well for this purpose.
In addition to pure convenience and efficiency, you'll be able to customize the number of divisions in a sweep (such as for saturation tracking).
Many of us have found that we are unable to match up the CIE at 100% color/luminance (or that 100% does not look good for various reasons) and opt for the 75% color space. The 75% space is, in essence, making the most out of a particular display's capabilities. Sweeping saturation over 8-10 points is taking this concept 1 step beyond. Combining the multi-point sat sweeps with color check patterns (and optimizing dE on color check) has provided me with the best picture on display's I've calibrated. (Thanks again, user nulsul!)
Once HCFR is generating patterns you can literally collect a 90 pt sweep (66 pt sat sweep + 24pt color check) while you take a short break. You're back and it's done. You can, for instance, make one adjustment to your gamma settings, and take a sweep in just a few seconds. This is particularly helpful when one point on the curve affects the point ahead and behind the point you're adjusting.
