Testing digital computer (IT) FPDs
This section describes how to test digital computer (IT) displays. You can test DVI on
digital computer displays using the 882C up to single link through the HDMI connector.
However you can test DVI digital computer displays up to full dual link on the 882D through
the dual link DVI connector. The procedures below describe how to test DVI computer
digital displays using the 882D.
To set up the generator to test a digital FPD:
1. Connect a single or dual link DVI cable between the DVI connector on the generator
and the DVI connector on the display under test.
2. Determine the formats to test. See “ Setting Source list of formats ” on page 43 for
instructions.
3. Determine the images to test. For digital flat panel displays, you typically want to select
images to test for pixel anomalies, persistence, photometry, and resolution-related
problems. For more information, see “
Selecting image ” on page 47 or Appendix B,
“ Image Reference .”
To activate the HDMI-D interface on the output port:
1. Press the Interface key. A listing of signal interfaces appears on the generator’s display
as shown below.
2. Choose the DVI-D item by pressing the adjacent soft key. The interface is activated and
the port outputs the currently selected image and format that is compatible with the
interface. An asterisk is shown beside the selected interface.
Alternatively, to activate the interface through the command line interface, enter the
following commands:
XVSI 2 // Selects the HDMI-D interface
ALLU // Applies the interface setting to the generator
To verify the test set-up:
1. Press the Source key to access the list of formats.
2. Choose a standard format (for example, DMT0660) by pressing the adjacent soft key.
Alternatively, you can load the format with the following command:
FMTL DMT0660
FMTU
3. Press the Content key to access the list of images.
