I'm wondering whether simply obtaining the DVE filters is better than just using my blue filter since I didn't like the results I was getting with a colorimeter.
The calibration guides I have read so far instruct to adjust the color setting by measuring the red Y value so that it is as close as possible to 21% of the white's Y reading. I would assume that the reason for adjusting color against the red primary is mainly for sets that have color management systems that allows you to adjust the other primaries and secondaries after color is adjusted.
When using a blue filter to adjust color, we are eyeballing the color setting so that the blue primary Y value matches the white's Y value. Since on our set we can only adjust color and tint, maybe the goal for adjusting color would be to minimize the Y difference between the target and what we get for all three primaries. On my tv it seems that the best "color" setting for the red is a bit low for the green, even more so for the blue. If you adjust "color" to get blue Y = 8% of the white's Y value, I would assume that the end result would be very close to what you had using the blue filter.
I'm thinking that since we have a single setting for all primaries, the most accurate setting for "color" would not be based on only the red, but it would be the setting that minimizes the Y difference between what is read for each primary versus their target values:
red Y target: about 21% of the white's Y value;
green Y target: about 71% of the white's Y value;
blue target: about 8% of the white's Y value.
Maybe on a PZ80 there is a single color value that produces Y readings on target for all three primaries. If not, do you find adjusting color against the blue primary better looking?
My TV is a 50FD18 and I am far from trusting my old Spyder 2 meter, but the readings I'm getting with the factory settings are similar to what is presented here for the UK version of it:http://www.hdtvtest.co.uk/news/panas...0080514109.htm
which differ from what I have seen reported for the US PZ80 quite a bit regarding the grayscale and the gamma, and there is not a color value that produces perfect intensities for all three primaries. I'll know for sure when I'll have the opportunity to measure my tv with a decent meter.
