My first attempt with HCFR to calibrate a Vizio GV47L 1080p LCD, using getgray, an Optix DPT-94, a Panny S97 DVD set to 1080i via HDMI to the V47.
The V47 has cool, normal, warm and custom in the color temp menu. For custom there are R/G/B adjustments. The usual other user settings are contrast, brightness, backlight, color, tint, sharpness. There has as yet been no reported success to access the service menu.
The V47 was first adjusted using getgray and DVE for BTB (brightness) and contrast. Then with DVE for color and tint using the filters. The R/G/B controls was used to set color temp visually (boy was that way off as I found later).
Set HCFR to the DTP-94, REC 709, camera gamma at 2.22. RGB at 16-235.
Sat the S97 to brightness +2 (to see BTB) and contrast -1, these settings are recommended in the S97 user forum and other reviews.
Then ran the gray scale 0 to 100 IRE getgray, next,
Using continuous measurement the R/G/B controls were adjusted on the 30/80 gray patterns and converged to about 100% on the HCFR info window. Iterated between 30% and 80% and achieved Delta e < 3 for both. The blue was way too high when I started. Reduced from 123 to 92 correct the Blue
Next, ran the primaries and secondaries many times against various contrast/tint settings (Only controls available for the color decoder on the V47), checking the CIE diagram each time. Ran the tint from -5% to + 5% with best at 0%. The color from 59% to 65% with best at 62%.
Final result not bad but blue out of wack below 20 IRE.
Note for owners of the V47:
The V47 'warm' setting was very close to the custom setting arrived at. And I repeated many tests using a Sony HX900 HDD/DVD recorder feeding the V47 via component scaled again to 1080i. The results were virtually the same.
Suggestions/comments welcom. Thought I would add my file since there are so few LCD panels reported, only 32ld700 that I could find
