+       There are several LCD test programs available.  One is built into this
+       configuration:  apps/examples/nx.  The NX example is a simple test
+       using the NuttX graphics system (NX).  This test case focuses on general
+       window controls, movement, mouse and keyboard input.  It requires no
+       user interaction.
+
+       There are several simple graphics examples under apps/examples/ that
+       could be configured to verify LCD/graphics operation:
+
+         a. nxhello.  Just displays "Hello, World!" at the center of the
+            display.
+         b. nximage.  Displays the NuttX logo in the center of the display.
+         c. nxlines.  Shows many fat lines.  This generally looks like a
+            "clock" with a cicle and a rotating line in the center.
+         d. nxtext.  This demonstrates scrolling text with pop-up windows on
+            top of the test.  The pop-up windows come and go without
+            corrupting the scrolling text.
+
+       See apps/examples/README.txt for information about configuring these
+       examples.
