    Well, now we have those references in an Amiga web site post.

    FitzSteve, Good luck on the manual!

    I'm using mt A1200T on a 4x3 screen at the moment with native screen of 1024x768 but I will be testing with a Widescreen TV when I setup my A4000/Mediator Elbox Tower

    Ok I have thus far figured out some more useful info based on examples in the mediator voodguide, picasso guide and what p96prefs has and the modeline calculator (http://www.arachnoid.com/modelines/index.html) shows:

    p96prefs->modeline results:

    clock = 21: [PIXEL FREQ]
    horizontal framesize = 20: [TOTAL PIXELS]
    vertical framesize = 10: [TOTAL V LINES]
    horizontal position = 18: [H FRONT PORCH (PIXELS)]
    horizontal syncsize = 17: [H SYNC (PIXELS)]

    I'm comparing the example 1360x768 in voodooguide with the modeline calculator and those are the closest results I can find so far.

    I'll attempt to follow this method to at least get some variables close to what they should be for 1440x900.

    Ok guys, I have some fantastic news:
    I have attached a screenshot of the result
    Not the greatest quality snap, but the specs are as follows:

    Samsung 940BW:
    Horizontal sync: 30-81kHz
    Vertical sync: 56-75Hz
    Resolution: 1440x900@60Hz
    Max Pixel Clock: 135MHz

    I provide the above so others with monitors with similar range syncs should be able to use the settings below too:
    P96 Prefs:
    Clock: 106.36MHz
    Interlace: No
    DoubleScan: No
    Framesize: 1904 (H), 932 (V)
    Bordersize: 0 (H), 0 (V)
    Position: 80 (H), 3 (V)
    SyncSize: 152 (H), 5 (V)
    SynPolarity, No (H), No (V)
    Frequency: 56kHz (H), 59Hz (V)

    Thanks once again to bdb. That Modeline Calculator helped me figure out at least enough of the required settings to make it play nice with my TFT

    Roy-Bates, there is an AmigaKit tutorial on that; it is only odd because half of it is drag-and-drop and the other half a combination of trial-and-error and electrical engineering voodoo

    Thank you for that doc, Johnim. I hope my discoveries helped too

    This is definately going to be very helpful to not only me, but probably many others that use mediators and others.
