Chapter 2 Testing Video Displays

Testing digital component video HDTV (CE) FPDs

This section describes how to test digital DVI and HDMI component video for HDTV flat
panel displays. The display responses shown as examples in the procedures use the
882C. However, you can also test dual-link digital component video with DVI using the
882D. The different selection options are provided for the 882D throughout the procedure.

To set up the generator to test a digital DVI component video HDTV display:

1. Connect an HDMI to DVI cable between the HDMI OUT (1 or 2) connector on the

generator and the DVI connector on the television display under test.

Note: If the display under test has a DVI-D connector, you will need a DVI-I to DVI-D
adapter.

2. Identify the high-definition component television formats to test. These formats are

listed after the composite television formats in the generator’s default Source list. Begin
with the first format (720p) in the range of high definition component television formats.
See

Setting Source list of formats

” on page 43.

3. Determine additional formats to test based on the resolution of the television display.

The television product specification sheet will provide information on what resolutions
to test. It is necessary to test only those resolutions with the supported scanning type
(typically interlaced for a high definition television).

4. Determine the images to test. For digital television flat panel displays, you would

typically want to select images to test for pixel anomalies, persistence, photometry, and
resolution-related problems. For more details on which images test these specific
display attributes, see

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

HDMI-D item by pressing the adjacent soft key. The interface is activated

and the port outputs the currently selected image and format.

Alternatively, to activate the interface through the command line interface, enter the
following commands:

VGA
