100Hz and NTSC?

[fattyboombatty]

does a 100hz pal tv show ntsc material in 100hz or 60hz? i force my dvd player to output pal, even for ntsc material. so is the ntsc material being shown in 100hz? did that make sense to anyone?

apart from the slight jerk on panning shots, which i hardly notice, it looks great.

If the player is doing a NTSC-PAL conversion then yes the output would be 100Hz.

Not if you're just outputting NTSC though.

I don't know if this is right or not, but I read that 100hz tv's display NTSC as 120hz.

I doubt your player is outputting 50Hz PAL, more likely it's PAL60 in which case the tv will double the refresh rate to 120Hz.

The jerkiness you see may well be due to the ntsc to pal conversion - several people i know thought what they where seeing was 3:2 pulldown when it was simply the ntsc - pal conversion, try using a pure ntsc signal in rgb

no, it really is. when it outputs pal it doesn't stretch the pic upwards/downwards like pal60/ntsc does. you know what i mean, don't you?

anyway, i watched return of the king R3 last night and the jerkiness was the worse i'd seen, so i switched the player back to ntsc/multi and it was fine. the matrix R1 doesn't seem to mind being forced into pal, so i guess it depends on the disc.

If PAL60 or NTSC are stretching the picture it sounds like you need to get into the service menus to change the vertical height and position settings for 480 line / 60Hz sources.

Whether you put 50 hz or 60hz pictures into a 100Hz tv, the tv will double the refresh rate.
