Hi All

I've just followed the excellent calibration guide and after a few runs have obtained good greyscale and colour calibration results in ColorHCFR. Unfortunately whilst the grey scale looks great the colours look pretty terrible so much so that I have resetted the CMS to standard settings.

Can you advise on what might be the cause?

I am using a eye-one display 2 coloremeter, dve hd basics disk and the AVSHD709 disk (for the colours).

Thanks

Got any before and after primary CIE diagrams?

Hi Kal
Firstly, thankyou for such an indepth and well written guide.

Foolishly I don't think I saved the 'before' colour figures but I remember the Delta E were well above 10. Will record tonight and post. I've included the HCFR results for the 'after' config.
Not sure if this is a factor or not but it seemed to be impossible to get the x/y value to change for the blue. Also, tint did not have any effect on the calibration - I assumed this is because I was connecting via HDMI (PS3).

Any help would be greatly appreciated.

Thanks again

Hi
Bit of an update (if anyones interested!) - would like to hear peoples thoughts.
When tuning the colours the Y value changes when tweaking the x and y values (via hue and saturation). The guide states that if the Y value changes I should leave the x and y values as they are. This mean't that the green was way off on the CIE and seemed to be messing everything else up. So to address this I set the x and y values and the changed the brightness (of that colour) to keep the Y where it should be. This seems to have sorted the problem as my DeltaE across the greyscale and colour are all well below 10 and mostly under 3.

Have I done something stupid here??

I also turned off xvYCC.which seemed to be messing things up too.

Please share your thoughts - would be grateful to hear from the experts.

Cheers

Hi

Attached is the CIE diagram for the calibrated display - as best as I can get after a couple of passes. While whatching Sky SD and HD the skin tones look a little washed out to me and on the orange side of things.

Thoughts and comments welcome.
