 The number of pixels in the shift register is automatically computed from these values.
 
+``n_planes`` controls the color depth of the panel. This is separate from the framebuffer
+layout. Decreasing ``n_planes`` can increase FPS at the cost of reduced color fidelity.
+The default, 10, is the maximum value.
+
+``n_temporal_planes`` controls temporal dithering of the panel. The acceptable values
+are 0 (the default), 2, and 4. A higher setting can increase FPS at the cost of
+slightly increasing the variation of brightness across subsequent frames.
+
+For simple panels with just 1 connector (2 color lanes), the following constructor arguments are available:
+
 ``serpentine`` controls the arrangement of multiple panels when they are stacked in rows.
 If it is `True`, then each row goes in the opposite direction of the previous row.
+If this is specified, ``n_lanes`` cannot be, and 2 lanes are always used.
 
 ``rotation`` controls the orientation of the panel(s). Must be one of the ``Orientation``
 constants. Default is ``Orientation.Normal``.
