2. Using the Image knob, select the first test image.
3. Repeat steps 1 and 2 for all formats and test images. 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 transition 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
gamma correction, you can use the
detailed methods for verifying these parameters on the
provided in Appendix B,
• 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.
• When testing for pixel anomalies use the Flat, Raster and Ramp images. Use the
Raster and Flat images to look for pixels that may be stuck On or Off, respectively.
The luminance should increase uniformly for the Ramp image. Also, look for
sparkles indicating problems with sampling.
• When testing for persistence with the animated images (for example,
Persist), look for bleeding or trails in the wake of the moving object.
Note: You can customize your generator to run through a specified set of formats and
images automatically or manually by creating test sequences. See
sequence" on page 87 for details.
