Default Pioneer PDP-LX608D ISFccc Calibration with ColorHCFR

Ok so it's been a number of years since I ventured into calibrating my display. I decided to give it another tune up with the help of the newly invigorated HCFR and ControlCal.

I would appreciate any help with the results. My intention was to fit gamma to a BT.1886 curve and colour to Rec.709. I seemed to have a lot of trouble with blue.

Here's the HCFR calibration file and here were my settings:

Contrast: 28 (I targeted a luma of circa 120 cd/m2 which also seemed to match full range without clipping)
Brightness: 0 (it was marginal as to whether this should have been 0 or 1, ideally I would have been able to split the difference)
Sharpness: -5
Color: 3
Tint: 0

Color Temp: Manual
R-High: -4
G-High: -2
B-High: 2
R-Low: 0
G-Low: 2
B-Low: 0

Colour Space: 2
Colour Management:
Red -4
Yellow +3
Green +2
Cyan +1
Blue +5
Magenta -2

Black Level, CTI, ACL, Intelligent Mode, DRE, 3DNR, Mosquito NR, Field NR, Block NR all "off"
IP Mode: 1
3DYC: Mid
Enhance Mode: 2
Pure Cinema: Standard
Text Optimisation: On

Gamma settings were:

1. R=1, G=1, B=0
2. R=0, G=0, B=0
3. R=0, G=0, B=-1
4. R=0, G=0, B=-1
5. R=0, G=0, B=1
6. R=0, G=0, B=0
7. R=0, G=0, B=0
8. R=0, G=0, B=0
9. R=0, G=0, B=0

BT1886 Actual
0.05 0.05
1.00 1.06
3.64 3.71
8.39 8.56
15.57 15.96
25.44 26.08
38.25 38.39
54.18 54.22
73.44 73.14
96.19 96.39
122.60 122.60

Thanks in advance for the help. I used an i1DPro calibrated with my i1 Pro and JohnAD's spreadsheet for 4-color correction. The player was an Oppo 93 and connectivity was HDMI via my Casablanca III HD. I'd also be interested in whether people think I should pass Y'CbCr 4:4:4 or RGB to this display given the Oppo. Pattern resource was AVS HD 709 disc.

I'm also interested in calibrating for SD and would be interested in a recommendation as to where to download a set of test patterns for this.

Thanks for posting Steve...

On the Pioneers, I'd recommend RGB vs Y'CbCr 4:4:4

Thanks Turbe. Presumably that RGB should be full range "PC" as I understand certain 16-235 Y'CbCr values fall outside RGB 16-235.

no, I (and Pioneer Gurus like D-Nice) recommend video levels, RGB 16 - 235 on the Kuros

some info Here, Here and Here

Also, do not have any Energy Save modes enabled

See this post here:

http://www.avsforum.com/t/1313052/th...#post_22171419

The answer as to whether to send Y'CbCr 4:2:2 or 4:4:4 or RGB should depend on which device is better at doing the conversion. I'm wondering of the Oppo with its relatively advanced video engine would do this better than the Pioneer. Even if true, I question whether limited range RGB is right.

that is in general, you need to know about the source's output but you need to find out what's best for your display. for the Kuro's, it's RGB 16-235.

That's what recommended, of course you can input another

You may also want to take a read in the 8G Thread

Lastly, if the Input is setup for Signal Type PC, several key controls are disabled.

Agree I need to test but if RGB has to be restricted to 16-235 then I would keep sending it Y'CbCr to avoid loss.

I have skim read the 8G Thread.

"Lastly, if the Input is setup for Signal Type PC, several key controls are disabled."

The only input I am using is HDMI from my Casablanca. (I won't even bother to calibrate satellite tv as I never watch it.)

I wasn't sure if you were doing this and I wanted to note the control limitation, but you can (or should be able to) select 'PC' for Signal Type on HDMI Inputs... options should be 'Video' or 'PC'

Ok I am now absolutely convinced that ControlCal is causing my display to tint away from blue even when the OSD is off. I can have, say, a 50% patch up with Controlcal running and HCFR running continuous measures. When I end calibration, as soon as I get the message that the session with the display has ended, the blue balance in HCFR bounces about 5% i.e. the blue bar moves from c100% to c105%. I can have nicely balanced greyscale and then when I end the Controlcal session my greyscale is off again - too much blue. it's driving me nuts.

That definitely is not normal behavior in ISFccc..

Are you pressing the SAVE Button (you need to in each memory to commit changes) before END CALIBRATION?

Also, does this behavior happen when also inputting RGB 16-235? I asked because I believe you are not inputting RGB 16-235 so it would be great to check that.... (I would not set the Input Set to Auto on the Pioneer for this check.

What about when you are calibrating with the OSD actually enabled?

You could also reset that ISFccc memory - RESET CURRENT

Yes I hit save. Actually I do this about twice after every change as I am so paranoid about it.

Have not tried RGB 16-235. Have not checked with OSD on.

But I can watch the levels in HCFR, end the calibration in ControlCal, watch the blue level jump, open the calibration in Controlcal and watch the blue level drop back down.

Are the settings still the same as in post #1?

What Drive Mode are you using?

Hi. "Page 2" settings have not changed. Others have.

The blue shift occurs as soon as I select "ISF Night" in ControlCal. It doesn't matter whether the OSD is on or off. So, given the calibration done with ControlCal on has too much blue, when I monitor the colour balance of, say, 60% grey via HCFR continuous measures without ControlCal engaged I see that blue is too high (e.g. 104%). I start calibration in ControlCal, select input 4, set and then as soon as I hit "ISF Night" blue drops back to a balanced reading. End the calibration setting and as soon as the message appears, blue bounces back up.

Drive mode is set to 1. (Thinking about it, I should probably change it to 3 but I would not expect this to be the culprit.)

EDIT: I've just had one thought as to the potential reason for the problem but won't be able to test it until tomorrow...

Unfortunately not. I've been crushed by work and haven't gotten back to it. Hopefully this week.
