    I have a moiré pattern on my F77 that I cannot get rid of.
    When I adjust the focus control on the flyback transformer the
    interference pattern disappears but the focus is too bad.

    I was told it could be the dynamic focus that is not working well. I
    did some measuments on the dynamic focus signal and found out that the
    amplitude of the high frequency part is less then the EIZO
    specifications.

    Did someone else experience this problem and have it repaired? I would
    be very interested in any experience regarding this problem.

    Best regards

  2. What resolution are you running your display at?

    Some monitors can run at resolutions well above those "supported" by the dot
    pitch of the tube...which IIRC will cause an unremovable moire distortion.
