       * The clock rate must be at most 65MHz, which is the maximum allowed value on Vampire boards.       * The clock rate must be at most 65MHz, which is the maximum allowed value on Vampire boards.

-        * If the horizontal resolution is less than or equal to 500, then the RTG driver will pixel-double the resolution horizontally.  If the vertical resolution is less than or equal to 300, then the RTG driver will pixel-double the resolution vertically.  This will help most low RTG resolutions to reach the minimum allowed Digital Video resolution (640x480), with the notable exception of 320x200, which will only reach 640x400. +        * Many monitors and TVs are flexible and support resolutions that are even lower than this minimum value.
