[EDIT 06-05-09: I have edited this first post to add some info from the first calibration thread and to make it a useful table of content to the new calibration and CMS thread]
This thread is a continuation of the original official RS20/hd750 calibration and CMS thread here http://www.avsforum.com/avs-vb/showt...8#post15314888 .
As the old calibration thread is mostly obsolete regarding CMS calibration with the arrival of the new firmware, we have decided to start afresh!
First things first, you need to upgrade the firmware before using the tips available in this thread.
A - NEW FIRMWARE
Where to get the firmware update (and common installation issues): http://www.avsforum.com/avs-vb/showt...8#post16355768
CAUTION: the new firmware erases ALL settings, so if you have general settings or calibration settings you wish to keep, make sure you make note of them before upgrading.
There is a wealth of knowledge regarding greyscale and gamma calibration in the original calibration thread. So here is a list of the most important posts which are still mostly relevant with the new firmware:
B - GREYSCALE: (from original thread, but info still relevant)
Before we get into CMS settings, the first thing to do is to get the best possible greyscale using only color temps adjustments, as this will make a huge difference with THX (and other presets). As already reported, some excellent tips are available here to achieve this from Mark Petersen Official JVC RS20 / HD750 Calibration and CMS thread - Page 22 - AVS Forum and also from Googer and others in the rest of the thread, here is one of Googer's great posts about gamma: http://www.avsforum.com/avs-vb/showt...#post15522847]
C - TWEAKED THX (from original thread, but info still relevant)
Once you have a custom color temp that gives you as perfect a greyscale as possible, the next step is to select the THX preset and enter the service mode (up/down/right/left/enter as fast as possible, either on the remote or the pj). [DISCLAIMER: be very careful when in this mode, you enter it at your own risks, if you make a mistake, don't blame me!]. You can then select a different color temp (for example the custom one you've just tweaked
), and this will be the color temp used by THX. You can now exit the service mode. This will make a HUGE difference to the ootb THX preset, as it will use a greyscale which is likely to be pretty good from 30 IRE up to 100 IRE, instead of a greyscale which is quite flat but off badly over the whole range, whether in normal or high lamp. More info about achieving this here Official JVC RS20 / HD750 Calibration and CMS thread - Page 29 - AVS Forum
If you like this "tweaked THX" preset, which is very close to rec709 - although slightly undersaturated for some - with a standard gamma, you can stop here and enjoy your PJ. If you do find it undersaturated, you can add anything from 1 to 12 - depending on your taste - to the general color control (I personally add 1-5 depending on source). That's it. Job done.
If you want to go one step further, and be able to use a custom gamma, sharpness and detail enhancement controls and adjust the gamut to Rec709, SMPTE-C or to your own taste, then have fun with the next section which is mostly about custom CMS settings...
D - CUSTOM SETTINGS, REPORTS and CALIBRATION TIPS with the NEW FIRMWARE
As members post reports/settings and calibration tips in the thread, I'll try to update this section with the most significant contributions (in chronological order).
Please let me know if I have forgotten something or if I get sloppy updating...

REST OF INITIAL POST:
I have done a first attempt with the new firmware, and the news is mostly good!
- The range for the controls has been extended from -60 to 60 (instead of -30 to 30), which gives enough range to dial the gamut perfectly without touching the general color control. Well done JVC!
- The linearity is good but not perfect. Most colors stay where they should, but green seems to be a bit oversaturated at 75% when calibrating at 100%. Nothing compared to the first firmware, but still not perfect. [edit: this was due to an error on my side, there is NO LINEARITY problem with the new firmware].
- I had only time for a quick calibration today, so I'll post more later. I attach my HCFR files for those who want to have a look at the details (EDIT: I used a brand new i1pro to calibrate).
If you want to try my settings (only after upgrading the firmware), here they are:
[EDIT: please do not use these settings, I and others have posted updated settings, see links above].
Contrast=0
Brightness=0
Color=0
Tint=0
Color temp (new lamp, probably not useful for most of you)

Red -4 -23 7
Yellow 22 -44 38
Green -5 -39 44
Cyan -3 -48 39
Blue 37 -8 -4
Magenta -6 0 -3
I didn't have time to do any fine-tuning on gamma etc...
