    While browsing the new features of the C3X I noticed that you can not only adjust the color temp like other Sim's, (but in a different easier way), you can adjust 'Gamma'.
    I understand that it somehow defines the linearity of the black to white steps, but I was wondering if there's any pattern and/or method you should use to adjust the gamma on your projector. I heard that NTSC should have a gamma of 2.2 and PAL a bit higher (could find the exact figure), but if you don't have some sort of tool to correctly measure it, how do you set up gamma with DVE or other tool?

    Thanks for your help.

    There is a gamma test chart on Avia.

    Thanks Jeff. I don't have Avia so I was wondering if there's any kind of pattern on DVE that can help me with this.

    I don't use DVE so not sure if it has gamma adjustment tests. Maybe someone familiar with DVE will let you know.

    No gamma tests in DVE.
