I know that 99% of all lightguns will not work on a 100hz/plasma/lcd/hd ready/full hd tv. But, I have a question about the 100hz tv's.

I heard that it's possible to change the 100hz setting to 60 or 50hz on a tv. If so, would my lightgun work on that tv? This might be a dumb question, sorry, but I need some confirmation. Thanks :-)
