NEO GEO AES 3-5 board RGB Checkerboard fix without mod

I brought a SCART cable that said to eliminate checkerboard pattern, well it actually works!!

It turned out that its just 2x 130ohm 1/4 resistor in the scart connector wired between pin 7-11 and 15 (The Red, blue and green signal) to the sync (pin20).

The yellow wires...




I cutted them just to check (just basically just making it like any other scart cable) and now I have a slight checkerboard effect....

Now I guess I am just gonna solder them back together.....

Just curious as how just putting 260ohm resistance per color signal to the sync fixes it?

Anybody can explain that as I would like to know more about this....

Thanks

Interesting info. Where did you buy the cable from?

I guess if you ask the seller he can also tell you the philosophy behind this implementation.
