When I send my video out (through the svideo) to an external video(ntsc) monitor, the image on the TV appears to be a lower color pallet compared to what is displayed on the monitor. For example imaging a spot light pointing directly onto a flat object, the fall off area seems to be banded/dithered similar to if you were using 256 colors. Also the image seems a little fuzzy. Is there any way to improve the output color to not create this banding from appearing around gradiants.
You could "calibrate" color video and sharpness out via video panel, but be aware that results will vary widely between television screens. Also, I wouldn't use S-Video out if you're using a modern teevee screen; modern tvs have much better comb filters in them than older S-video hardware has, though I'm not certain this will solve your problem.
