Composite 240p Performance

by Eli Krause

For composite decoding this set uses a Sanyo LA76600M-TLM, a 3-line digital comb filter. Depending on the console/revision, blending effects may be broken, and edge artifacts are slight to moderate. It displayed an exceptionally high amount of dot artifacting across all consoles tested. An example of the many dot artifacts are highlighted in the second picture below in red. Using an external notch filter to decode composite instead (such as is available in a RetroTink 2X, 5X, etc.) and sending that to the set's component input would blend all dithering patterns, reduce edge artifacts, and remove nearly all dot artifacts.
