Testing Video Displays
General video display testing procedure
This section provides an overview of the video testing process, which involves connecting
the generator to the display under test, selecting a format appropriate for the display, and
then selecting images to exercise the display to ensure proper functioning.
Making physical connections
Use the following table to connect the generator with display under test.
Setting the video output mode
If the application involves testing similar displays with one type of video signal output for
extended periods of time (for example, in a production environment), use one of the
following modes:
•
Digital Friendly mode
– Digital formats are output without change, while analog
formats are temporarily switched to digital. This mode is available only if the generator
has a digital option (DVI, LVDS, or HDMI) installed.
•
Analog Friendly mode
– Analog formats are output without change, while the digital
formats are temporarily switched to analog.
For information about using these modes, see “
Summary of special modes
” on page 19.
When you need to test various video signal outputs and color encoding methods (for
example, in a repair center), disable all friendly modes, and enable the Status Display
mode (see “
LCD
” on page 7) so that you can determine the current configuration. Then,
