Looks to me like the probe is seeing a smaller difference than you are seeing by eye...
That wont help.

The plasma being unstable is not good either.
(What patch size are you using on the plasma, and how are you displaying it? I assume you are using the Eizo integration for that display.)

How are you applying the LUT for the displays?

Also, have you re-profiled the displays with the LUTs active and compared those profiles?

Oh - and I should add the Eizo is a lot more accurate than the Plasma's calibration - the plasma values are more inaccurate!
You may just be seeing the limit of the Plasma due to its instability, etc...

With unstable I mean, the 3rd digit behind the comma. Maybe its the plasma noise, since I had a small patch, about 6x6cm?

Haven't tried the eizo integration. I did view a 50% grey with the DI-System and there just loaded the calibration luts for both displays. I feel I can only trust my F32 DLP.

Will try the eizo integration next.

Thanks Steve

What I mean is the xy values read from the Eizo were more accurate to Rec709 than the xy values from the plasma, showing that the Eizo calibration looks to be accurate - while the plasmas looks poor.

The Eizo integration is great! More precise than ever!

Steve, is there a way to influence the brightness?

What do you men?
LUTs should not be used to control brightness - that should be via the display's own controls.

really pleased the calibration with Eizo integration is working well - it should!

In the lightspace's eizo-mode the cg243w is in cal-mode, which gives no control over the display's brightness setting. Its at about 117cd/m². When I work with projector I would prefer of course lowest possible luminance of the gui display.

In that case you can use the 'LUT Manipulation' tools in LightSpace to lower the output.

That will work fine

Thanks! Will try that!

When profiling a K10 to a Jeti 1201 for a plasma is there any settings I should be aware of , or would it be the same as profiling a K10 to a I1Pro ?

All the same.
Chose the best pre-set in the K10 for the display type before matching.

Job done
