Testing HDMI displays

264 Chapter 9 Testing HDMI Sink Devices
This section provides procedures for testing HDMI displays. The procedures below can be
performed using the front panel or the command line interface.
To test HDMI displays:
1. Set up the 882 for HDMI output. See
2. Press the Source key and select the first test format.
Alternatively, you can load the format with the following command:
FMTL format_name
FMTU
3. Press the Content key and select the first test image. For digital fixed pixel displays,
you typically want to select images to test for pixel anomalies, photometry, luminance,
centering, resolution, and persistence. For more details on what images test these
specific display attributes, see
Reference."
Alternatively, you can load the image with the following command:
IMGL image_name
IMGU
4. Repeat steps 1 and 2 for all formats and test images.
Note: You can customize your 882 to run through a specified set of formats and
images automatically or manually by creating test sequences. See
sequence" on page 244.
Use the following guidelines to verify proper operation:
• When testing photometry such as chrominance, use the ColorBar, SMPTE133, or
SMPTEbar images. Look for missing bars which may indicate a dead or
unconnected channel. Also, look at the transitions between the bars; they should
be sharp and distinct. Each bar also should be uniform in color and intensity across
its entire width.
• To test luminance, you can use the
correction, you can use the
for verifying these parameters on the
B, "Image Reference."
• When testing for centering, use the Outline images. The detailed methods for
verifying centering with the Outline images
are provided in Appendix B,
• When testing resolution with the Grill images, you should be able to see individual
and distinct stripes in all areas of the display at all four resolutions.
