wow thanks for the swift reply.

Indeed I don't have serial ports on this computer.

I will enable one tomorrow.

Yes, I use Haali's Renderer to watch movies, and it does make use of the LUT

I already used the Spyder2pro ICC profile software, and it works really fine on 
the projector.

But I'd like to try with your software because it seems to achieve better 
deltaE measurements through the HCFR software.

I only want to enable full screen tests patterns so the spyder2 can offer 
proper measurements.

so after I have a .cal file, can I convert it to .icm or do I have to use 
dispwin ?

Thanks again!
