Color/Graphics Display Test
When you choose the Color/Graphics Display Test, selection 6 on the
Main Menu screen, the program tests nine different characteristics of
the display and shows nine messages in succession as the characteris­
tics are passed (see Figures 4-19 to 4-27). If any of the characteristics
fail the test, the error message shown in Figure 4-28 is displayed.
