Abstract
The states of various kinds of control signals, such as a horizontal synchronizing signal, a vertical synchronizing signal, a display timing signal, etc., that are supplied from an external signal source to a display device, are inspected. In the states of various kinds of control signals supplied from the external signal source HOST to the display device DSP, (1) the vertical synchronizing signal (VSYNC) is converted into a display signal of red (R), (2) the horizontal synchronizing signal (HSYNC) is converted into a display signal of green (G), and (3) the display timing signal is converted into a display signal of blue (B) by a control signal inspecting circuit. The states are displayed in color and brightness on the screen of the display device DSP, so that these states can be simply visually inspected.
