It shouldn't make any difference to to photo frame though.

I can't automatically download the patches on the photo frame, but I guess, here too, the patches used for initial measurement to adjust display are always the same. Am I right? So I can generate them, download them on the photo frame, and use the same pause script with dispcal... >You could create a test 'chart' of a few key colors (ie. 10% step >grey wedges, if you can fit 10 squares and still measure them, >or coarser steps if you have to), and compute the relative Y >values you expect at a reasonable gamma, and then use spotread -dw >to measure the colors to guide your adjustment. Sounds good! Thanks for all these good ideas :o) -- Frédéric
