Help calibrating Pioneer MXE1

[TheCrow]

Hi I purchased a Spyder TV a while ago and have just started to plot/adjust the gamma of my display.

The MXE1 has many adjustable settings most of which I understand but I must admit there is one series of adjustments I do not know the purpose of.
These are the C.Detail adjustments.
The manual states:

C. DETAIL can be adjusted for each color.
• C. DETAIL RED: The – side approaches magenta, and the + side approaches yellow.
• C. DETAIL YELLOW: The – side approaches red, and the + side approaches green.
• C. DETAIL GREEN: The – side approaches yellow, and the + side approaches cyan.
• C. DETAIL CYAN: The – side approaches green, and the + side approaches blue.
• C. DETAIL BLUE: The – side approaches cyan, and the + side approaches magenta.
• C. DETAIL MAGENTA: The – side approaches blue, and the + side approaches red.

Can anyone explain what these settings do, under what situation you need to adjust them and how to do it?

Thanks
Paul

They alter the available gamut of colour the plasma can show. They alter how the colour is mixed within that gamut. They affect greyscale at same time unfortunately. They can really ony be adusted if you have a spectroradiometer ca[able of reading the primary and secondary co-ordinates accurately. My strong advice is to NEVER adjust the RGB only CMY

Gordon...

p.s. or you could pay someone to do it for you...

Thanks for the answer Gordon.
I think I get the gist of what you are saying but it definitely sounds like something I personally should leave alone.
Just out of interest would this be something included in an ISF calibration?

[Gordon @ Convergent AV]

It would be included if the calibrator had the understanding and the tools necessary to adjust it. Accurate measurement of device primaries isn't possible with some tri-stimulus pods that many ISF folk use. Thats why I suggested you need a spectroradiometer. The Tri-stimulus pods get oversaturated and give false readings.
