  • Using PowerDesk to drive a fixed frequency monitor

    I've got a Cornerstone Color 19 (which is a
    OEMed HITACHI Model: HM-4419-D) that I want to use with a Millennium by modifying the MGA.MON file.

    The monitor, according to: http://www.bigmonitors.com/support/p...s/pdf/rc19.pdf
    Has a range of 27-79kHz for the Horizontal Scan and a range of 55-80Hz for the Vertical.
    Pixal Clock is 135Mhz, and they recommend 1280x1024 @ 63.5 Hz...

    According to: http://si87.com/Support/a-to-h.html
    the CORNERSTONE COLOR 19 CD1619S/30
    has a Horizontal Frequency of 78khz
    and a Vertical Frequency of 72hz
    Sync Type(s) Supported: Composite Sync, Separate Sync, Sync on Green
    Maximum Resolution: 1280 x 1024

    I have had some luck creating custom settings using a Horizontal Frequency of 78kHz @ 640x480, 800x600 and 1024x768, but whenever I adjust the Horizontal, the Vertical changes itself & sets itself to Hz settings over 100... What I get is doubled images stacked vertically. Positive and negative sync both "work", giving the same results.

    If anybody knows what I need to change / how to calculate the settings for MGA.MON to use this monitor, I would be grateful.

    Thanks! Quin
