First I'd just like to say thanks docrings for the HUGE amount of very useful info you've posted here about the HL-S TVs. I've learned a ton already and I just started to do a self calibration on my 5087 with HCFR and a i1-LT. I do have some questions though...
I'm doing my initial cal using a PS3 over HDMI. I did my grayscale last night using AVIA, being upscaled in the PS3, but I'm going to do it again tonight using the 1080p .ts stream IRE/pri/sec fields that found somewhere. (rename them from .ts to .mpg and the ps3 will play them natively). I'm guessing if I set the PS3's display output to RGB full range, that I have to calibrate to 0-255 and not 16-235.
- Spyder2 probe, change 300ms-->500ms, extend time for dark, average readings
Should I do this with the i1-LT as well? It seemed to give pretty stable dark readings with it off. I didn't change the delay.
- DNIe menu: Use a 100% (or 100 IRE) window with HCFR/Spyder probe, and adjust sub-contrast to a constant reading (xyY) of Y to ~100 (best in a dark home theater setting). [One can also opt to adjust the DB iris in manual mode to the same Y luminance to ~100. (For me that was an iris setting of ~145, but I'm back to DB on now. See this link for changing to manual iris)]. For my TV with a new bulb, it was a subcontrast setting of 97.
When using manual iris control to adjust the Y luminance, what should the sub-contrast be set at? Also, 100cd/m^2 is too dim for my taste. My HT is in my livingroom, and it's the family TV that we watch all the time with brighter than optimal room lighting. Should I just set the iris to get a Y of 100 for the calibrations, and then just go back and open it back up when I'm finished?
When adjusting the grayscale, are the WB_color_B_COEFF and WB_color_C_COEFF the only settings that I have to adjust the grayscale over the entire luminance range?
On to color....
- Input HCFR colorx,y & White x,y readings into the CCA menu for Redx, Redy, RedY, Greenx, Greeny, Whitex, Whitey, etc. Be mindful that the Y values must be multiplied by 4 prior to entry into the menu. To change luminance (big Y), you must next adjust the bigY value in CCA so that each color/hue is a standard % of WhiteY value (which you earlier set to a readout of 100). See the HD table at the bottom for values. Spyder2 readout values should be: RedY 21% of WhiteY, GreenY 71% of WhiteY, BlueY 8% of WhiteY.
So after I do a primaries and secondaries sensor acquisition, I just plug those numbers into the CCA menu, multiplying the Y values by 4 right? And then I go back and divide the whiteY value by the corresponding % for each pri/sec and then change those numbers again? Or do I throw up the color fields and _measure_ the Y values again, and adjust them so that they're correct % of whiteY in HCFR? This step really confused me.
- Scroll down to WB SPREAD. Activate by selecting it and hitting the right arrow on your remote, and get the OK. [It is very important to note that it "spreads" this calibration to ALL the other input channels. Only do this on the FIRST channel you calibrate! For others, just manually to fine-tune ONLY the input channel you are currently calibrating.]
What settings does WB Spread actually "spread"? Is it everything, or just the settings for grayscale and color? (iris?, gamma?, NR?...)
Sorry for the novel, thanks in advance!
