I redo the calibration this morning. Here are the results I was able to reach

I started with Color Management First and I worked on RVB curvers and Gamma after...

I will tune the Plasma tonight but the results are already excellents...

I found the 9 point control useful in sorting out the 90IRE. Basically I adjusted the 80IRE gamma point and it flatened the grayscale at 90 and 100. I found that if you try to adjust all the gamma points results go way off. I think they should only be used in certain areas in addition to the RGB Highs and Lows.

I'm looking into using CalMAN to use a custom white point target where I use the primary colors and D65 without using the Pioneer CM.

I do think we are splitting hairs though and just trying to eek out the last drop from the display. The pic quality is absolutely stunning. Even my wife commented on it last night and she is a technophob.

You make a good point. There doesn't exist a perfect display (or video chain) so you will always have to make sacrifices.

My entire point is about where to make that sacrifice during calibration of a Pio G8 with ISF C3 interface. Since I think that when using Color Space 2 with Pio 8G you are very close to standard already, it is best to sacrifice using the CM at all and instead focus on adjusting grayscale and gamma as best you can using the primary colors unadjusted.

Last time I started with Gamma and RVB and I saw a big impact when I changed colors...This time I do the opposite and it was easier to calibrate...

I needed to change a lot the primary colors (all colors). The values are in comments in the HCFR files...

But the impact on the grey scale was manageable...

Do you know what input do we need to use to put my settings (Input 4) as a basis for DTV ?
And For Home Gallery (For photo...)

I have always started with adjusting CM since the grayscale depends on RGB coordinates and white point coordinate.

What source are you calibrating against?

It's very interesting that you don't get much of an impact on the grayscale when moving the color using Color Management. I certainly don't get that behavior

I have Input 1 through 9 listed in ControlCAL. I believe that DTV is Input 5. No idea about Home Gallery though.

Thanks I will test Input 5...

The source is a PS3. It's globally a neutral source...

The behavior of my display is propably different...

Default Some results

I can't get consistent result with the ISF, During Cal. Blue will shoot off the chart then return to normal. The results I get with CalMAN are far more volatile than with HCFR, I'll to get those to you.

Here you go. Let me know what you think
These were taken 24 hours apart no changes other than results.

The grayscale has some changes..... do you think they're acceptable?

Here are the final results regarding ISF NIGHT:

They are better....

Delta E : below 1.6 (from 20IRE to 100) except one value at 30 IRE : 3,2
Gamma : between 2.16 to 2.21
Excellent CIE Diagram...

So it's possible with a LX508D to reach something close to perfection....

I'm not surprised because the ColorHCFR does an average of measures (and it far better I think)

The Input 5 is in fact the PC Entry...

The measurements seem good, although not moving the primaries.

What sensor are you using? Could you perform some "day after" measurements and post them?

What do you mean? My English is not good and I don’t understand the end of this sentence.
Does it mean that I didn't change a lot the primary?

The sensor is an I1PRO and I will do again measure tonight. But I'm sure of the results. It will be very close...The I1PRO is excellent and gives repetitive results day after day...

I mean you didn't move the red,green & blue position using the colour management....

It's false. I changed to followings parameters :

R : +6
Y : +3
G : -9
C : +2
B : +4
M : -3

Hmm, OK, sorry for leading you the wrong way. Did you find the correct Input # for DTV? I use an exteral box so I use one of the HDMI inputs.

Hum.... looking at the CIE chart the primaries look out of target...was it your choice or you couldn't get them in place?

What ColorSpace are you using in HCFR Colorimeter SDTV or HDTV?

My Calibration has been done in SDTV (if it's not the case at your side you can change the value). Red Value and Blue Value will be perfect. Green will be a little bit over saturated...

Many of the DVD I see are standard DVD so I choose this option...

What I see is: It should be easier to adjust the colour to the reference using HDTV.....Because for me the most difficult thing was to adjust the green colour...I needed to increase red and blue colour. It I decrease a little bit these values the results will be perfect...

.............. SDTV. But as most valuable calibrators state, it is more important to gain a flat grayscale and gamma curve rather than primaries in place...
