Whenever I do the black level pattern test, I can tell that my blacks do not align properly, some bars are purplish, some greenish, some reddish... slightly, yet I can tell. I remember the original HCFR 220.127.116.11 did show 0-10% IRE/gray scale but each reading would provide different results. AFAIK you need a spectrometer to properly measure blacks. I do know that at some point I had my blacks almost perfect to my eye, but now any attempt to fix them results in screwed up RGB WB 10-90% IRE.
It does show 10%. HCFR probably doesn't display errors at 0% video levels because most meters can't read color accurately that low anyway, spectros included (spectros generally have worse low-light ability). You can do a 20pt run and see how 5% video levels are measuring by going to Measures -> Parameters -> and setting the number of grayscale levels to 20; then use the 5% step grayscale patterns.
But you're still obviously limited by the controls on your display and how the display performs. Remember that the software only sees the points that you're measuring... it doesn't see the in-between points. If you have a 10pt white balance, doing a 2pt calibration first might help with banding. Other than that, there's not much else you can do about that. Some displays with 10pt systems are just a pain in the ass to get smooth gradients, while others with even just a 2pt system might have a smoother looking grayscale, albeit probably with higher errors overall.
I use my HDTV as a PC monitor in PC 4:4:4/RGB Mode and I use 0-255 full range! Maybe 0-10% IRE affects only full 0-255 range, but not 16-235???
If your display is expecting the RGB range that your PC is outputting then it shouldn't matter if you use full range or limited range. Although I recommend full range whenever possible when it comes to PCs, because outputting limited can sometimes cause banding.Edited by rahzel - 11/10/13 at 1:12pm
