By the way under Windows Control Panel Uninstall, Chromapure's version number is listed as 2.1.

My dvd is the pattern generator, I use the 0 % IRE windowed pattern from the color hcfr pattern set to measure with. Just starting out calibrating with chromapure for the first time but have calibrated my tv using an i1display lt before so do have some knowledge but always learning new things. Let my plasma warm up for at least an hour I have the i1display 3 pro i am not too sure but this doesn't need to be on the panel while it's warming up. Also I don't know if this is a bug but when I click on measure then continuous in the white balance module the 3 RGB bars appear overly big like the entire window is minimized and doesn't fit the screen properly I have to scroll down to see the percentage and then back up to see the xyY data. While I scroll down also i see a completely different module that appears momentarily in the background, like it's see through.

When selected from dropdown menu in 'Color Management' they do not appear to make a Duo selection.
Manually changing pattern causes error message but no 75% pattern.
Incidentally they are not listed within Duo Control Panel either so currently back to using AVS disc from Oppo.
This problem does not appear if the normal 100% patterns are selected.
Could it be that the 'built-in' patterns should be used?

You will need to use the AVCHD disks.

Since I've done that I get a General Fault error concerning "baud rate". Whenever I try to use autocal (or test). CP then closes down. I've tried playing with buad rate settings since but had no luck.
The other guy with the issue is installing for the first time and trying to add in the Radiance. gets the same issue

Just to slightly correct, that I was updating my version of Chromapure Pro to the latest version (having uninstalled the one linked to a few pages back), so not a fresh install. I can use it manually, but the autocal gives me a baud rate error. I'm being sent a known working USB to serial port adaptor to try (thanks to Ricky ) as it could well be this causing the issue (though my existing adaptor can update the Lumagen firmware fine and the config utility works too, but these adaptors can be a bit quirky). I may well receive the adaptor tomorrow or Saturday so I'll post back if it works OK.

If you cannot see the entire white balance RGB chart at once, then your screen resolution is too low. The pattern takes up about 690x610 pixels.

"After running auto-cal for the first time in 2.3.1, when you exit ChromaPure you will get a "Cannot
create XML" error message. The next time you start ChromaPure you will have to setup the signal
generator again. From this point forward, everything will work normally and your settings will be saved
for future sessions."
As per my OP, I have re-added the Lumagen as a signal generator but this is where I have the issue. if I try and use it in an autocal once re-added I get the GPF with the "baud rate" error and CP crashes I cant use the radiance with CP autocal at all. Even hiting "test" for the Radiance produces the error

I used 75%A/75%S from the GCD disk to adjust the cms is this the same pattern needed when I first measure with everything on the tv set to defaults. It's a samsung pn51d6500.

Duo patterns have been at 75% stimulus in the Duo for several years.

Check the Duo patters labeled 75%, these seem to refer to Luminance, not saturation.

No, use 100% saturation for all gamut measurements, except in special circumstances. 75% stimulus is correct.
