Thanks. Really useful to copy (and rename) a matrix to a different Klein location

What is wrong with the calculation of Klein Instruments?
What would be the advantage of a different calculation method of the Color-Matrix?
The Black-Matrix and the RGB-Matrix of the K10-A remain the same.

If it's just a matter of making any XYZ correction, it's quite easy to do it with the stored measurement results.
One sets the color matrix of the K10-A to zero (factory) and corrects the XYZ values in the LightSpace result file with the desired matrix. This can be done with Excel macros, for example.
This is a big advantage of the open and well structured XML format of LightSpace/ColourSpace.

Klein doesn't use the "classic" formula. They preferred another RGBW luminance balance which won't give you perfect white luminance. So red luminance might be back into tolerance but white will not be as accurate as with the classic formula.

I already created some Excel spreadsheets by the way, one of them applies TMC to profile created in LightSpace. If you are interested, write me a PM.

The second NIST Yoshi white paper was an enhancement on the classic formula. I believe that is what Klein is doing.

Not exactly Tyler, as far as I remember, the second paper introduced luminance to the first formula with a balanced "mix" between the four colors luminance being considered, where white is the most important. Klein just decreased the "importance" of white in favor of other colors luminance. Which is also suggested/not forbidden from the paper itself. So for example, if with the original luminance balance of your FCCM (made on a WOLED) verification looked like this:
R G B W
Y 1.6% -0.1% 0.4% 0.0%

x 0.00 0.00 0.00 0.00

y 0.00 0.00 0.00 0.00

With Klein custom Y balance, it might look like this:
R G B W
Y 1.2% -0.5% -0.1% 0.4%

x 0.00 0.00 0.00 0.00

y 0.00 0.00 0.00 0.00

Which it might look like a good thing but it's not. You solve a problem to introduce another two. But I'm not blaming Klein in any way, when they did that WRGB panels didn't exist and, in effect, no one even noticed the difference, @ebr9999 did (give to Caesar what's of Caesar).

Here where I have explained what I have computed: https://www.avsforum.com/forum/139-d...l#post59390290


And any Klein matrix I have generated on my OLED has that "smart" adjustement.

If not, let us know and we'll look into adding the required changes.

Hi, Steve,
thank you for your offer, but you have more important things to do at the moment and we want to keep the K10-A-Tool as simple as possible.

Maybe I can give you hope there. The thing with the storing of a finished matrix did not let me rest and in the meantime I succeeded in creating a program on pure C++ basis, which saves any 3 x 3 Colormatrix into the Klein K10-A. Let's see what we can do with it.

Finally! Well done! The only thing we can do with that is using it with RGB panel. With WOLED it might be better to use it with contrast at 100 or measuring with preset 0 (Klein LCD) or blank and wait for a surprise that Riccardo @frumenzio and me are trying to do to you guys... no promises.
