TOPIC


    Does Apple have a listing of Composite Monitors/TV Tuners that are
    compatible with the 660AV & 840AV computers?. Most monitors seem to scan
    in such a fashion that the menu bar and right side of the screen are lost.
    Has Apple tested the AV's to see which monitors compensate for this?

    I'm running out of the Video-out RCA jack into the monitor and switching
    in the control panel according to the AV documentation.

    A number of schools have brought this up as an issue. Is there a
    difference if we use the S-video output?


DISCUSSION


    It sounds as though you are using the monitor in the overscan mode. This is
    exactly how a television set operates--a portion of the video display is
    off the screen. This is not a problem when watching television but it is a
    serious inconvenience when using a NTSC receiver (TV) as an output to a
    computer generated signal. The solution is to operate the TV in the
    underscan mode. To do this you must open the monitor control panel and
    select the lower resolution (512 x 384) via the options button. This is
    the underscan mode and will allow you to see the entire raster when you
    "switch" to the TV.

    Using the S-video output from the computer to drive an S-video
    compatible monitor will provide a slightly improved signal. However, the
    improved performance is very subtle and may not even be discernible under
    certain displays.

    Finally, because of the almost endless number of third party monitors in
    the marketplace, Apple does not keep track of nor maintain a list of those
    which may or may not be compatible with our ever growing CPU line. I
    recommend you contact the individual vendors who will inform you as to
    their compatibility with a particular Apple computer.
