methods for verifying these parameters on the SMPTE133 image are provided in

Appendix B, “Image Reference.”

• When testing for centering, use the Outline images. The detailed methods for

verifying centering with the Outline images (Outline0, Outline1, Outline2, Outline3)

are provided in Appendix B, “Image Reference.”

• 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 (

Cubes and 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 Chapter 8, “Working

with Test Sequences.” for details.
