I have a Samsung, and this is how I connected my NES, it works fine. Well as fine as an NES can on an LCD anyway.
I guess that only works for Samsung. I just tried it for my PS1 on my Sharp that does have composite inputs and it will only show up in black & white from the green input in the component section.
