Thank you very much!

Thank you very much!

Thank you very much!

Why Black 62 61 62 ? can correct 62-62-62 ?
Why Neutral 5 120 120 119 ? can correct 120-120-120 ?
Why Neutral 8 188 188 187 ? can correct 188-188-188 ?
White 224 223 219 ? can correct 224-224-224?

With great respect, Andrei.

It's a fairly inelegant solution. I have no programming knowledge so I appreciate that changing this may require a major software rewrite but bt.1886 has been available for manual calibration in Calman for a long time now.

I wish I could justify the cost of a radiance.

I have no idea. I thought that this was weird too. On the other hand, the difference is negligible.

This is a bug in Excel when opening older versions (97-2003) with the new versions.

Here is one done with Excel 2010.

Tom,
I want to start my auto cal with the new chromapure 2.4 and I don't find the start button?
Please advise
Anybody else has this problem?
Down, on the second page from auto cal I have only generate calibration report and cancel auto calibration.

Trying out 2.4 Tonight: Problem with connecting to my Lumagen Radiance
Select Lumagen Radiance: cannot select any selection in Select Colour Format nor Colour Resolution
Select Duo, then I can make my selections, which then messes up my Radiance. Why can I not make selections when the Radiance is picked?

This is not a connection problem. We have never included color format and resolution options for the Lumagen within CP. These are selected in the device itself. Nothing has changed here.

The Duo selections have no effect on the Radiance.

BTW, there is a good reason why we don not include resolution options for the Lumagen. By default the Lumagen's resolution mode is auto, which means it will automatically detect the display's resolution and then set to that. Having a manual resolution selection only gives users the chance to screw it up. We may enable selection of color format in the future.

Could not get patterns to come up from the Radiance, despite going through all the instructions shown in your Video tutorial. But, choose the Duo and Selections, then the Radiance reacted. When choosing the Lumagen, the current program running stayed on the screen, and no Patterns came up when going to the White Balance, and the Lumagen Bar..

Could you rephrase this? Other than reporting that the Radiance patterns did not come up, I really don't understand what you are saying here.

If test patterns are not appearing, then you need to recheck the signal generator setup window and make sure that all of the correct parameters are selected.

Like maximus said, I too no longer have a "start" button for auto cal. Tom can you please point me in the right direction

thanks
post #4035 of 5348
I was wondering, for a plasma calibration, does the patterns resolution (720p, 1080p) and frame rate (60p, 24p) matter or would any combination yield an identical result? I can image some sort of link between that an a meter being able to "sync." with the screen.
Any opinions on this?

And ps: how about the international keyboard lay out?:-)
post #4036 of 5348
atabea,
If you decrease the size of the chromapure window ,you will see that the start button will move up,or down.
post #4037 of 5348
Thanks Maximus, never had to do that before. Didn't even know i could reduce the size of the window.
post #4038 of 5348
BTW, as I think I have mentioned before, Lumagen recommends that prior to running auto-cal you set the 100% grayscale point using the display's own RGB grayscale control. With recent changes that they've made to the firmware related to 125-point calibration I think that this should now be considered a requirement rather than a recommendation. I am seeing some strange and not-very-good results from auto-cal sessions that require large changes at 100% using the standard Lumagen adjustment.

It might make a difference. I haven't tested this. Feel free to do so and report back.

Every time a new version is released, and I mean EVERY time, someone always has some complaint about this feature or that that didn't make it into this release. There are a lot of pending issues on my plate and not every request will be fulfilled immediately. This is obviously not in this release.

I s'pose that could be a PITA but it's also a good thing.....feature requests mean interest in the product and a desire to see it better. At some point maybe you could consider a release that incorporates most of your outstanding feature requests....In the meantime I'm hoping to give this release a workout in the coming days....

I don't mind feature requests. In fact I encourage them. How else can I know what people want? It is just not possible to incorporate every outstanding feature request in every release. Some issues are more important than others, and I have to assign priorities.

Every feature request will get get released. I just can't guarantee that it will be released on the time schedule that pleases everyone.

If I recall, I got a lot of criticism in a previous release because control of the signal generators within CP was not included. OK, that is now in this release. Other requests will be incorporated in future versions as well. Please be patient.

Count me among the silent majority that appreciates all the work you do, and especially your accessibility and responsiveness to customers.

Problem solved: because I go between 4 different TVs here to calibrate, 1 with the Radiance XE-3D, and the other 3 with iScan Duos, to keep everything on par, the Laptop Serial Port is set to 19200. No problems with the other calibration software, but ChromaPure has to have the Serial Port at 9600. Then it works. Setting the Laptop to 19200, and the Lumagen in ChromaPure to 19200, results only in a secondary flicker, but no Patterns. Set both back to 9600, then the Patterns come up. Probably that's why the Duo got a responce with the Radiance because then the 19200s matched.
post #4045 of 5348
Something I should have mentioned, but simply forgot, is that for reasons that escape my understanding I now find that I get MUCH better results when doing a Lumagen grayscale calibration when It is done from the bottom up (10%-100%), rather than from the top down (100%-10%). In recognition of this, we need to change the order in auto-cal as well. I already have this in beta, so it should be released in the next day or two.
post #4046 of 5348
The ability to control the Radiance and the DUO from inside CP is a great feature and much appreciated. The DUO will wear your hand out and who the heck wants to learn the Byzantine interface on the Lumagens any more than they absolutely have to.

Thanks Tom.

All very good stuff and much appreciated.

Don't have the AutoCal, but your Manual Mode always started at the Bottom. But, I've found, as soon as 100 is brought to spec, it throws all the others off, and they have to be re-done. Then every time 100 is brought back in line again, same again. It appears 100 affects all the others more than, any other reference point. (Forgot, sometimes 10 changes things as well.)

Always found that if I got Green in line from 100 to 10, then Blue, then Red, everything went quicker, and easier, but the Auto function seems to keep working with all 3, and doesn't seem as smooth a calibration.
post #4048 of 5348
If you calibrate the white balance gains in the display at 100% prior to doing anything with the Lumagen, then you should be able to start the Lumagen grayscale calibration from the bottom. Then 100% shouldn't actually need any work when you do get to it. However, you'd probably want to take a 100% reading first to get a reference point for the other levels.

1. Adjust 100% using the Display's own RGB grayscale controls.
2. Using the White Balance module, now adjust every other point using the Lumagen control within CP.

Note: I just found that the relevant variable is not top-to-bottom or bottom-to-top, but what control is used for 100%. The White Color control, which used to work wonderfully at 100%, no longer does. It can be used, but only if calibrating bottom-to-top, and even then you'll have to go back to 80 and 90% to readjust. On the other hand, using the 100% grayscale adjustment in the Lumagen works fine, does not have the interactive effects, and it doesn't matter whether you go top-to-bottom or bottom-to-top.

Finally, Lumagen recommends that you do NOT use the 100% grayscale control. I think because it can result in banding artifacts. This is why they recommend using the display's own control to adjust 100%. Once that is done the rest is a breeze.

FWIW, I am seeing none of these issues using the Duo. Of course, the Duo has other shortcomings, but for basic 10-pt grayscale, gamma, and 6-point gamut calibration it is hard to beat.

Final Note: Other than at 100%, where it may be necessary, you should not adjust green when doing grayscale. Stick to red and blue adjustments only. Green has too much of an effect on gamma.

Tried fine tuning the Lumagen tonight, but found the + or - .5 increments too great. Where can the settings be changed to + or - .1 ? In the lower values, + or - .5 shot the RGB all over and was hard to adjust correctly.
