This shift is introduced by the massive intervent on the hue slider of the cms (+50 if I remind well).

The other thing that you can see in the picture is the collapse of the green 75%sat.
It's too near to the 50%sat.



It's not so irrilevant for a buyer that spend so much money and pretend a correctly working CMS!



Yes, what you say is real but what you describe is the normal working method of a general color slider and not a real CMS.
This CMS works like a general color slider: one for each colors.



I repeat: This blue-hue-shift is so evident without reading it with my i1pro.



No, I remember a good linearity in the thx mode.
Anyway in the next hour I'll give it a full verify.



You're wrong!
A good working CMS DOES NOT CHANGE the saturation of a color when I'm moving the brightness slider of it!
And when I'm moving saturation or hue a GOOD CMS DO NOT CHANGE the luminosity of the related color.

Yes It is true that this programming ERROR is less massive in this firmware release but still persists.
And we have to tell it!

Try to put your i1pro in continuos reading and then play a 75%sat green pattern.
Visualize in HCFR the CIE diagram.
Now you can se the green cue ball on it.
Now change the value of the green brightness in the cms.
Now you can se the mark moving on the CIE diagram.
It goes saturate-desaturate.
It change its x-y coordinates.

In this condition is very difficult to calibrate.

Now I post my pre-cms file, post-cms file and post-cms file only with primaries and secondaries @75%stim.

Acta.
P.S. Can you explain better what is the banding issue (with some screen shot plaese)?

I don't have the same issues. I don't have this blue hue shift. I don't have a linearity problem with saturations either. If I did, I would say so! I was one of those that pushed very hard for a CMS fix.

I don't think the issue is the CMS.

Agreed that the controls would be slightly easier to use if adjusting saturation did not also affect brightness but this is very easy to correct and it does not introduce any issues into the final calibration.

I'll say it again but you have to be very aware of the fact that your i1Pro is going to have issues reading blue correctly. Mine did. You have to trust your eyes quite a bit to know what a 50% Blue sat pattern is supposed to look like.

I actually think that this is reasonably good. Yes, blue is off more than I would like, but you haven't got blue properly calibrated at 100%, so it is not surprising that it is off in the other saturations as well. Other than that, green at one point and yellow at one point are off. The rest are within what I would consider to be a reasonable range of tolerances.

I have a USA HD750 version and would prefer not to void my warrantee.

Is there a USA download site?

Where are the upgrade instructions? I downloaded the file but haven't opened it yet. Is there a read me or text file with instructions in the compressed folder?

I visited the JVC USA support site again today and the firmware link has now been posted.

Have any problems been reported with the FW v1.1 upgrade?
To clarify, not problems doing the upgrade, but problemes with v1.1 itself?

That is the European link. The firmware link and update instructions are now posted on the USA site so I am good as long as Windows Vista 64 supports it. Thanks.

I did the UK v1.1 RS20 update.
In that update it asks you to specify RS20 or 750.
In the US version I see it lists 750 only.
Can that be used for the RS20?
I wouldn't normally think about it except that there was that differentiation for the UK version.

From site:

DLA-HD750BU firmware update
This update improves IR sensor detection and expands Color Management System adjustment range
View the DLA-HD750BU update procedure
Download the DLA-HD750BU update file (zip format)




Thanks.

Mike


- EDIT -
Ok, reading PDF answered:
"Procedure shown in this document is for DLAHD750 and DLARS20"


So, why was it different for UK FW v1.1 update?
Is the US and UK FW v1.1 the same?


Thanks (again)

In this case is very evident! And what I see is confirmed by the blu points in my gamut....
When I play the blu pattern @0%sat I do not see any dominance.
When I play the blu pattern @25%sat I see an evident violet dominance.
When I play the blu pattern @50%sat I see an evident violet dominance.
When I play the blu pattern @75%sat I see an evident violet dominance.
When I play the blu pattern @100%sat the blu returns blu without any evident violet dominance.

Hi, Tom.
Yes blu was intentionally calibrated like that.
In this way I reduced the hue shifts of the other blues (@25%sat, @50%sat, @75%sat).

Before this trick my blu@100sat. was perfectly on target but the blu-hue-slider was @ 60 !!
and the shift of the other sats were much more wide.

Tom I've a question for you: what are the values in the CIE94 column?
Maybe the delta xy ?

thank you,
acta.

There are several dE formulas. CIE94 is a LAB-based formula endorsed by CIE in 1994. It was designed to improve upon some problems found with the 1976 formulas, the LUV version of which is used by HCFR. I try to keep the CIE94 value below 1.5, but anything 2.0 or below is fairly benign.

Hi,

Tom, is it the best result you have had on the HD 750 ?



IMHO, not so far, but the green is very low at 75 % (as the red), no ?

Don't you have in your files, the measures of "Y" (white point and primary and secondary) for each saturation levels ?

Hi,


I saw your files, it seems you have some problems about luminance on green and yellow (on red too) and another on saturation on blue under 100 %, but at 100 % saturation, all seems "perfect".

If you say you didn't saw the linearity problems in THX, I rather would stick using this mode.

The round dots are the measured points, the square ones are the reference points. Measured with a Minolta CS-200, white luminance of around 13 fL on a Stewart GrayHawk.



The question is: is the linearity better in THX?
Maybe I should try to get the test patterns for measuring the intermediate saturation points, I don't have them for the moment...

Having now completed it, it seems that my earlier calibration was pretty much spot on.

No need to reinvent the wheel and that is a good thing. My numbers ar so close to those posted earlier that I am sure that there is no functional difference between them.

Hi Guys,
I am just starting out on calibration having just obtained an i1Pro and Calman a few days ago.
I would really appreciate it if you could make some comments on my first real run at CMS with my 750.

I have some basic understanding only. The dE results look OK but what about magenta luminance? Any other comments?

I don't know if this has been reported, however I fine tuned the standard "6500" temp setting(not one of the custom settings) using the "offset" adjustments(the only ones available in that mode) entered the service menu while in the THX mode and to my surprise the "altered" 6500 settings had already been picked up by the THX mode.

I can't help you, as I'm a complete newb with calibration myself, but I also use Calman and the i1Pro. I have yet to give calibrating this thing with the new firmware a go though. I think I'll do that tomorrow. However, when I calibrated it before, I had trouble getting accurate results when calibrating the grayscale below 30 ire. I shot the Calman guys an email asking if it would be worth while to train a Spyder to the Pro like LDVD does. The responses I got back were that I need to make sure I enable the low trigger / low light handler. I had no idea there was such a thing, so I'm quite curious to try this again. They assure me that the i1Pro is accurate when using this feature. I just figured I'd throw that out there for you (or anyone else using Calman).

Does anyone else use Calman and the i1Pro?

Hi am new to this .Just wondering can all calibratation done by the cms menu or do we have to go in to service menu for jvc rs20? And if so what keys on the remote have to be pressed? Is it up ,down,right, left and enter in fast sequence? Thanks

Ignace.

Just remember that the locations of the intermediate saturation points are only valid for a gamma of 2.22. If you are using a gamma other than 2.22, the location of the intermediate points changes. There is a tab in my spreadsheet that will show the new locations, calculations provided by Bill Mitchell.

These aren't my measurements. I just plotted the numbers Actarusfleed posted. I only measured 50% saturation points on THX. Yes, green at one point and red at one point are off further than I would like.

I don't see much point in reporting the luminance values for the saturation scales. After all, the purpose is to test saturation linearity, and Y is irrelevant to that issue.

BTW, it is important to put all of this into perspective. When you start measuring saturation scales, you now have 24 data points instead of 6. If you want to look at different levels of stimulus at each, then we are talking about 100 data points (6*4*4+4 levels of white). Thus, if a couple are off that is much less of an issue than it would be if we were only measuring the traditional six points. Also, this is a level of exactitude that professional reviewers and ISF calibrators routinely ignore. I don't mean to suggest that it is not worth doing, but only to emphasize that we are pushing the limits of performance expectations for consumer products.

Very true. At a certain point, we are expecting near perfection for under $7500 msrp. Hard to imagine that 5 years ago we would be even close to expecting this kind of performance in this price range.

I want to purchase a JVC HD-750. Will I be able to use a 92" screen and fill it corner to corner side to side in 16.9 at a throw of 10'9" and a seating position of 8'6"aprx.? I'm looking to mount the projector on my book case which is also my headboard. Ceiling is 8' and so is the built in adjustable book case behind my bed. Thanks

About saturations.
I just finished a complete calibration.
Something is really wrong between 95% and 100% saturation.
My parameters are very close to LDVD settings

I am sure this has been answered elsewhere but I cant find it by searching

I am using a Crystallio II so I can use either RGB, 4:2:2 or 4:4: color space.

Can anyone tell me which would be best and why?
Thanks

I have calibrated my RS20 using the AVSHD patterns out of my PS3 Blu ray player and posted the results earlier in this thread, and now would like to calibrate the Dish Network sat. input. I have the HDNET patterns recorded on my Sat. DVR, but I am not sure those patterns will do any more than setting color, tint, brightness and contrast. How can I adjust grayscale and the CMS for the Sat. input ? I have Avia and DVE dvd's to calibrate my dvd input from my Denon 3910 dvd player, but I am not sure how I can calibrate for the satellite input ??

Are these last questions from we newbies to calibration steering the thread off course? Should we start a thread just for us? ie "New to RS20 Calibration Thread"

Very interesting! You have clearly taken more measurements than anyone else.

I don't have reference to your actual readings right now, but overall I recall this looking very, very good. Something does appear to be going on, mainly between 97% and 100% saturations. What do you think it is? I don't have the tools to take as many readings as you do but I don't see any issue when comparing 100% and 75% saturations.
