    I'm wondering if it's available (free or paying for it) a full
    electrical specification of VESA standards with tolerances, es

    vga is [email protected]:
    hsync= 31,46KHz
    bsync = 60Hz
    what is the tolerance on HSINC and VSYNC?

    is that standardized?

    Thanks,
    Fil

    probably.

    In my experiance with old fixed or multi-sync displays 0.5Khz horizontal and 2hz vertical can
    make a difference. modern displays with microcontrollers and OSD are much more lenient.

    Computer video cards derive the sync rate from ordinary quarts crystal
    clocks, if you do the same you should be fine.

    Bye.
