This paper analyzes the jagged effect that occurs in raster image display devices.Our main goal is to identify the true causes of the jagged effect, and the initial hypothesis is that between sampling and reconstruction errors the latter is the only cause. The developed methodology used to perform the research about the true causes of the jagged effect is based on the creation of four test situations where we control the occurrence of the two possible causes to be tested. In each test situation we investigate the occurrence of it, sampling error and reconstruction error in the time and frequency domains. The final conclusion based on the result of these analyses is that between the reconstruction and sampling errors, the reconstruction is the only one that produce the jagged effect.
