I am hoping that either Robert Clark or Mflaster answer these questions. I read earlier where Mike was able to correct his gamma tables using the Davis programming cable. I also read where Milori and Mike were able to create a gamma.exe file that allowed one to fix via HTPC their gamma tables. The gamma.exe way seems too burdensome( hard ) for me. If I could get some pointers on how to proceed I will be forever in your debt as I am forever in debt.
