    3537Description 
    3638----------- 
    37 This driver provides some access to the Brooktree bt869 found on some video 
    38 cards (like the 'Voodoo3 3000').  Typically, the output can be either an 
    39 s-video connection or composite video.  Resolutions supported using the 
    40 chip's built in configurations are 640x480 or 800x600.  Other possible 
    41 implementations may allow for double resolutions with some decimations 
    42 (e.g., a monitor running at 1280x960 but the TV out getting every other 
    43 pixel for 640x480).

     44800x600.  In addition, a 720x576 PAL mode and a 720x480 NTSC mode, 
     45both without overscan compensation, are supported - a convenient 
     46configuration for video playback.

    4653Driver Features 
    4754--------------- 
    48 Stanards: (US) NTSC or PAL (PAL untested) 
    49 Resultions: 640x480 and 800x600 
    50 Depths: 16 bit or 32 (I forgot if 24 bit worked OK, it probably does) 
     55Standards: (US) NTSC or PAL 
     56Resolutions: 640x480, 800x600, 720x576 (PAL only), 720x480 (NTSC only) 
     57Depths: 16, 24 or 32 bits 
    5158Colorbars: Switch on the built-in color bar generator. (FYI- using a blue 
    5259filter, you should see only alternating bright stripes of equal brightness. 
    5360Adjust your TV's color and saturation if this isn't the case.) 
     61SVideo: composite or s-video output.  Also, theoretically, RGB output, though 
     62this isn't tested and will require that your card presents all three DAC outputs 
     63(the 3dfx Voodoo3 doesn't) 
    5464 
    5565In your XF86Config file, you should have these entries for NTSC output:
