I was recently informed that the PAL SNES supported RGB output. And me having a 46" Samsung LCD naturally wanted the best picture quality possible out of my console =)
I've been reading up and I know all about the diagrams and the "official" RGB cable configuration, modding gamecube cables, etc. But when when I got down to business it wasn't quite as clear.
I myself bought a couple of pre-modded cables
One didn't work properly (the bugger forgot to desolder the composite capacitor) and the other worked pretty much as well as the first one after I fixed it.
However, there was one clear issue. The picture looked.. "pixelated".. "dithered" or what not.
Then I got a hold of an unmodded 3rd party Gamecube cable to test for myself
And all I did was to desolder the capacitors and it worked (in my opinion) a lot better!
Now I remember reading on these forums (or some other) that some leads have built in resistors between composite and ground, which these good cables actually have (I verified with a multimeter) so that's really the only difference between the two cables.
I also noticed that the two "bad" cables doesn't even have a pin for ground in the snes connector so they can't be modded to work in the same way! Bastards...
Edit: I just noticed that only one of the cables where missing pins, the other one has a full set. Pretty weird though.
Anywho, when I started to ground R, G and B the picture on the good cable started to look like in the first pic again.
My personal preference is obviously with picture nr 2, but I'm hoping someone could shed some light on the technical details behind this. How is it supposed to look? Maybe my Samsung LE46A656 has a daft scaler? (and the other 50" brand TV at work I tried with, which is not very likely).
Any information would be greatly appreciated!
