TOPIC



    We would like to utilize the AV technology in the Quadra or Power Macintosh computers, but we understand it has an auto-gain feature that cannot be turned off via software, or at least in the Quadra 840AV.

    There are some indications that the auto-gain feature in the Power Macintosh may be turned off under software control and the gain adjusted manually. How can this be done?


DISCUSSION


    The Fusion Recorder utility program that comes bundled with the Macintosh Quadra 840AV and the Power Macintosh AV models doesn't support video gain (black level or white level), or contrast control. If you purchase VideoFusion software from VideoFusion, Inc., you will have the ability of adjusting the contrast control on only the Power Macintosh AV models.

    There are third-party companys that provide hardware like the Radius' Video Vision or SuperMac's Video Spigot for greater video control on the Quadra 840AV.

    To locate a vendor's address and phone number, use the vendor's name as a
    search string in the Tech Info Library.
