Using a computer to generate the test patterns via HCFR's "View Images" feature is really a big time saver.
I used to use the AVS disc and manually advance each chapter. A single run could take 10 minutes and I had to be there consistently advancing each pattern instead of sitting back having a beer or catching up on reading or whatever.
More importantly, the high “cost” of each run deterred me from making useful but time-consuming measurements: You can discover quite a bit about your display from 20-step grayscale runs or looking at the saturations of all primaries and secondaries, but you’re not likely to bother if you have to manually press a button 50 times for a single run just to see the effects of one settings-change.
Getting the “View Images” feature set up properly has resulted in at least tripling the rate at which I can measure the effects of adjustments, and I am three times more inclined to collect interesting data for later analysis and comparison, and most importantly can I get to a good watchable result (and start viewing actual content!) three times faster.
Even if you are doing all these calibrations with the sole aim of getting movies played on your Blu-ray player to look right, you can still benefit by using HCFR to do most of the calibration work. Once you are pretty satisfied with the measurements your settings produce with HCFR patterns, you can always touch up your settings with the AVS disc.
Two things to bear in mind:
First, your computer and your blu-ray both need to connect (either one at a time or using an HDMI switcher, AVR, VP, or whatever) to the exact same digital input on the display. If your computer has DVI out, it’s a simple matter to get a DVI-HDMI cable and plug it straight into whatever HDMI input your blu-ray player is normally plugged into. (DVI and HDMI use the same video signal- not sure if displayport introduces any issues.)
Second, if you are using a plasma and don’t change the defaults, HCFR will almost certainly appear to produce incorrect results:
Under measures.. generator.. configure, you will probably have to change a few things specific to your situation. In my case I use these settings:
Window size 37% (to match the 37.5% windows used on the AVS disc)
Grayscale (GDI): 16-235 (because my display is expecting video levels)
So if you want to experiment with automated runs in HCFR, go for it, but just be sure to sanity-check this scheme as soon as you set it up: compare two measurement runs using identical settings on the display, one where the patterns were generated by the blu-ray player, one by HCFR, MAKING NO CHANGES (and allowing no time) between the runs. The measured values should be close to identical whether HCFR generates the images or you get them from the AVS disc. If something is obviously wrong (eg black, white, gamma or gamut looks obviously different) then either give up and go back to using the disc, or find the cause and fix it before proceeding.
Final note: The patterns included in the program are adequate for measurement runs, but for setting black levels and certain other activities I still use the AVS disc. It’s still incredibly valuable, even if you don’t use it for each and every grayscale measurement.
