A600HD with LCD32"

What do you mean by "colors flash?"  Why would that happen, even with a not-too-sharp composite connection?

Some LCD TVs do funny things with composite due to the additional processing that goes on before the video gets to the screen.  I've noticed less of this with s-video.

I have a 15" LCD monitor that the colors "flow" on in certain situations when using composite, almost like waves in water.

I've been pretty happy with AmigaManiac's S-video solution, though RGB to component does sound nice, even though I've only got one screen in the house that could take advantage of it (though it won't do 50hz modes, kind of useless..)

The funny thing is that in games, the colours doesn't flah and looks ok.

I've noticed it more on static screens with color gradients/alot of dithering.  Never really bothered me much, given the disparity of the technologies I was combining (1980s with 2000s.)  If it bothered me enough, I've got a nice PAL/NTSC CRT sitting in the garage I could hook up... hey, that screen would look great with my black A500....
