The PC software may reads that coefficients from device memory (firmware) and use the coefficients to interpret the sensors data. The every type of display should have it's own coefficients in a colorimeter. > > Please note that only the single shaper matrix profile looks good on > my screen...

The device sensor may be just dirty. Or the devise may be broken. Do You insured, that You have select the correct display type while dispcal and dispread?
