"Greg" …
Ah, Powerstrip does actually retrieve the LUT successfully after I’ve loaded it from the Windows control panel,
but *only* if Powerstrip is invoked with the "Write directly to palette DAC" already checked. If it’s not
checked before having changed the LUT in Windows, Powerstrip seems to reset the LUT as soon as
the setting is checked, to whatever LUT data Powerstrip currently has in it’s own tables. Very tricky.

Greg, in the moment I don´t have the time to check Powerstrip. I had tried to read and write the LUTs according to the Vesa-Vbe specs, but this didn´t work for my Matrox cards (it´s assembly programming).
I suspect that these specs are not accurately cast into software, because the Windows programmers who know the direct access to the graphics card´s registers don´t care anymore about the Vesa specs. On the other hand I had success programming the pixel clock (vbe-3.0 for Matrox G550).
See you later ..
