Its your 3 year old D2, get a new one or profile it to someone's probe that you know is working correctly.

@Nashou66

you think the trouble is the colorimeter



but ... is this really for sure?



i prone to buy an i eye one display lt ....


i dont have someone with an probe or an colorimeter that he can borrow me for a few days

Sorry i don't know anything aobut the the average lifetime for an clolorimeter...

The guys at Spectracal told me that the lesser probes like the Spyder,s and the Display2.s are just consumer probes that should be replaced every year. its just how they are made, the sensors are not the types that can be calibrated, you can oly profile them in the software to an known existing probe once they fall out of spec, i had one go bad after 8 months.

@nashou66


okay thanks for help but where i can get an profiles and how do i use them with color hcfr and my meter?


maybe i think about it to buy a new one later maybe an eye one pro... but for now it's to expensive for me

btw: how about the eye one pro? is the lifetime higher than the low price products which you've count.

and does it pay to buy an used eye one pro? or later i ve the same accuracy problems like the other ones


and how about the X-Rite ColorMunki?


thanks for help

I got my i1 LT in the mail yesterday, and I'm wondering if there's something wrong with it. The measurements it takes for luminance and gamma are darn close to what they should be, but the color is way off. It says something like 700% for red, 300% for blue, and -100% for green. When I look at the CIE diagram, all my points are in the black part near magenta. Also my footlamberts are really low, under ten even though I'm using a plasma.

Edit: By the way, I've turned blue and red all the way down and green all the way up, and it still reads red and blue really high and green really low, even when I'm looking at a green field.

Was reading an interesting review about a new set here:
http://hdguru.com/the-new-king-of-hdtv-displays-panasonics-tc-p54v10-reviewed/458/
and came across this:
"The Gamma user control, set to its numerically highest level (”Normal”), measured 2.25 average. There is no service level or user gamma tracking adjustment available, an omission we would like to see remedied in a display of this caliber. Blu-ray discs are mastered for a 2.5 gamma display" (emphasis mine).
Huh?
So I tried desperately to get mine (a different set) to 2.2 and now it's "supposed" to be 2.5?!
Any thoughts?

Hi,

I'm sorry if this has already been asked. Kal's guide states that the correct way to set the Color control is so that the Y value of a 100% red window is 21% of that of a 100% white window. I reckon this is only valid for HD, isn't it? What would the correct percentage be, when calibrating against the SD PAL standard?

Thanks in advance.

Hello Everyone,

Just a quick post to say thanks to Curt for the best guide out there for consumer calibration done with the least expense.

I have been using an Eye One with the GetGray disc and HCFR for the past 5 years. Based on other guides and with effort I have achieved good results on numerous displays.

When I came here today to give the little donation and become a club member I found that I had signed up as a regular member some time back and forgotten about that (my AV bookmark list is way too long). Perhaps too much focus on AVS and all the distraction and time one can spend there.

Anyway, printed out the guide and find that although I have had good results, my methodology has been a bit lacking. As you all understand once familiar with the process, measures in the HCFR program are quite simple. It's the starting point of max luminance that can be hard to get right. Always thought just make sure you don't have the colorimiter in it's shadow, keep the sensors about 3-4" from the screen and go on.

Not so it would appear. Little changes in angle of reflectance, at least with the EyeOne had my range with a 100IRE window at a variance of at least 2 ftL.

Lesson learned.

Just upgraded from a BenQ PE-7700 to a W6000. The 6000 seems to have a very usable CMS with an ISF mode. Should be fun.

Forgive my first, and long winded, post. Promise to keep it pithy in the future.

Happy Holidays,

Joe

This "greyscale calibration" guide into a comprehensive "colour calibration" guide including measuring primaries and secondaries, and complete colour decorder adjustments hue/tint/saturation/etc. It is recommended that HCFR is set with the color space definition that matches the calibration test pattern source. This sets the reference standard within HCFR for the color gamut only and has nothing to do with the greyscale calibration itself, since D65 is the same for all standards.

[Mr Incredible]

I have had a JVC RS20 for about 200 hours use and think it would probably benefit from a calibration. I was reading through the Guide for Dummies to see if perhaps I could give it a go.

One thing I don't quite grasp is why greyscale is adjusted before the primaries. In my mind if the three primary points were way off the REC709 standard "traingle" and I had already done a greysacle adjustment, wouldn't the greyscale be affected by a subsequent change in the one or more primaries?

[fuzzyreets]

Let me first say thank you to Curt for this awesome walkthrough. I'm totally new to all this calibration stuff but I found this and have been reading it for days now. This brings me to my question. The thread is at https://www.curtpalme.com/forum_archived/viewtopic.php@t=22754.html

If anyone has any interest in helping me, I'd greatly appreciate it. Thanks very much.

Hi Kal

Brilliant guide thanks alot.

Im using a LG 50PK990 Plasma, Sony S370 Blu Ray and an EyeOne i want to adjust my colours as in part 8 of the guide but now i'm stuck much to my embarrassment.

I have burnt the AVS HD 709 disk but i cant find the specific window i need could you give me the disk pathway from the opening menu for this instruction please

"Cue up your AVS HD 709 test disc and skip to the 100% white window pattern by selecting "10% Grayscale" -> "100% Gray window". 100% means that the window is at 100 IRE. Write down the Y (Luminance or brightness) reading as seen by the sensor"



and what Y value should i expect to get for my display, is the 39.012 value in the guide for projectors or direct view ?

many thanks

One important question for me.

I tried to set the brightness using the DVE and the result was 47, than itried using the AVS 709 HD disc ant the brightness is 51. Which one is correct????????

[redfox001]

The newer led tv's seem to have sharp peaks in their color spectrum. I heard people say that therefore the color readings from the eye one pro are not accurate. Is there a correction for led tv's in the software or will this be done in future? Regards.

HI!

you tested and compared a Spyder2 and a Display2 with RGB readings
the Display2 reads RED to low it seems?

do you know how the Chroma5 is when reading RGB?
is it more close to a reference meter?


i heard other people saying the same about the Display2
that it reads RED low about 5%

why isnt that compensated in the programs when you calibrate a display2?
i mean if its known that it reads red 5% lower than a reference meter?

if i calibrate my tv that have 10Point IRE adjustments to the same line that the picture shows for the Display2
do i get closer to a correct result ?

[kal]

[kal]

[Patrik G]

ok thanks for the answer.
i also think its strange if all D2 meters have the same error reading.

i had the Display2 with HCFR
sold that meter yesterday

so the next step i would think off is to get the Chroma5 and Chroma Pure program
http://www.curtpalme.com/ChromaPure_Chroma5.shtm

i hope the shippment to sweden is fast
im going to order it pretty soon

as you are the expert here
what version du you think is best for me PRO or Standard?
i own the LG 47LX950N (LX9900 in the US) FULL LED TV
but as i can see that tv has no pre calibrated offsets in Chroma Pure?
can i go for the Standard Chroma5 instead?
or is the PRO still more accurate?

also a dummies guide for Chroma5 and ChromaPure would be great.


also thanks for the dummies guide!
without that it would be impossible for a newbie to do a calibration.
