    A few issues to remember when connecting VGA monitors to the
    Macintosh LC III:

    * VGA monitors may have variances when purchased from different VGA
    monitor vendors. Test a particular monitor for compatibility with the
    Macintosh LC III before buying.

    * VGA monitors from different vendors have different image quality
    specifications. There may be significant differences between Apple-
    brand monitors and VGA monitors. Look at the monitors side-by-side before
    buying.

    * When a VGA monitor is connected as described above, the resolution is
    640 x 480.

    * The bit depth supported depends on the amount of VRAM installed. The
    Macintosh LC III ships with 512K of VRAM in one VRAM SIMM socket and is
    expandable to 768K.
