Never seen a one on my Samsung 61 inch LED RPTV and by BD55 using SD-DVD. Same is true for my Pioneer DV-610 and sd-dvd and my Samsung 61 inch LED RPTV. Do you have a sd-dvd that you use that shows them clearly on your monitor Winston?
"'Jaggies' is the informal name for artifacts in raster images, most frequently from aliasing,[1] which in turn is often caused by non-linear mixing effects producing high-frequency components and/or missing or poor anti-aliasing filtering prior to sampling.
Jaggies are stairlike lines that appear where there should be smooth straight lines or curves. They can occur for a variety of reasons, the most common being that the output device (display monitor or printer) does not have enough resolution to portray a smooth line. In addition, jaggies often occur when a bit-mapped image is converted to a different resolution. This is one of the advantages that vector graphics has over bit-mapped graphics — the output looks the same regardless of the resolution of the output device. The effect of jaggies can be reduced somewhat by a graphics technique known as anti-aliasing. Anti-aliasing smooths out jagged lines by surrounding the jaggies with shaded pixels. This can be done in a computer or in a printer."
