Could you please check those freq. specs again ?
I am under the impression that all those models will accept both 60Hz and 50Hz signals, that is on the component input (if fitted) YPbPr you could input both 480p@60 (NTSC) and 576p@50 (PAL).

You would want your display to support both freqs in order to watch NTSC and PAL under the best conditions.
