881/882 Video Test Generator User Guide (Rev A.22) 55

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.
